Note The floor covering must be suitable for the respective loads, observe the manufacturers instructions.
Determination of the permissible load capacity The basis for the stated load capacities on pages 9 to 15 are real load tests according to the following test procedure: Single load (point load) The specifications for the permissible point loads are based on:
Loading area Ø 50 mm Spacing from edge ≥ 25 mm Deflection ≤ 3 mm
50≥ 25
50 ≥
25
High load zone Whether point or area load: Within the scope of the specified values the fitness for use of a floor is assured for the entire floor surface. The possible deformation on the edge of a surface is higher than in the middle of the surface when under load conditions. The probability of a deformation is reduced with the increasing distance from the edge and the capacity of the floor also increases. The monolithic pre-fab floor screed Brio exhibits a considerable increased capacity at just 25 cm from the edge. Knauf defines this areas as the high load zone, which can be used with an increased point load and/or area loads. The constructions marked with a in the tables on pages 9 to 15 feature a high load zone. For these Brio systems when the spacing to the edge of 25 cm, a 1 kN enhanced point and/or area load can be planned. For the required Brio system and possible floor covering you can receive the increase in load capacity of the high load zone on request. A high load zone is always significant when heavy furniture or room elements are placed. For example, a representative conference table, a large aquarium or a book shelf that divides the room. Brio offers sufficient safety reserves in these cases. Dimensions in mm250

Introduction Note
Usage instructions Notes on the document Knauf System Data Sheets are the planning and application basis for the planners and professional installers with the application of Knauf systems. The contained information and specifications, constructions, details and stated products are based, unless otherwise stated, on the certificates of usability (e.g. National Technical Test Certificate (AbP) and/or general building authority approvals abZ) valid at the date they are published as well as on the applicable standards. In addition, design and structural requirements and those regarding building physics (fire protection and sound insulation) are considered. The contained construction details are examples and can be used in a similar way for various structures of the respective system. At the same time, the demands made on fire resistance and/or sound insulation as well as any necessary additional measures and/or limitations must be observed.

Intended use of Knauf systems Please observe the following:
Caution
Knauf systems may only be used for the application cases as stated in the Knauf documentation. In case third- party products or components are used, they must be recommended or approved by Knauf. Flawless application of products/systems assumes proper transport, storage, assembly, installation and maintenance.
General notes on Knauf systems Terms Knauf Pre-Fab Floor Screed systems are screed systems made of high- quality monolithic gypsum fibre units.
Field of application Knauf Pre-Fab Floor Screed systems are used in interiors in dependence on the load, substructure and floor covering as systems on insulation layers, separating layers, on light levelling mortar and equalization materials or as heated screed. The systems save on installation thickness and weight due to the low layer thicknesses. They are thus ideal for renovation of older buildings or for new constructions with tight deadlines due to its drywall construction method. Knauf Pre-Fab Floor Screed systems improve the fire protection and sound insulation without introducing additional moisture into the building. Knauf Pre-Fab Floor Screed systems are also suitable for domestic areas of high humidity and barrier-free bathrooms. Application areas
Residential buildings Office construction Schools Hospitals, etc.
Top coverings Prefabricated parquet and mosaic parquet (chequered design) Floating laying of parquet Carpet, PVC and linoleum Tiles and natural stone up to 120 cm edge length
Fire resistance effect Knauf Pre-Fab Floor Screed systems protect the floor slab from the upper side of the room against the effects of fire as a floor construction and assures the stability of the basic floor/ceiling for the duration of the fire resistance class classification.
Sound insulation Lw,R = weighted impact sound improvement index of the pre-fab floor screed system (calculation value)
Lw,P = weighted impact sound improvement index of the pre-fab floor screed system (test value)
The verification of the new DIN 4109:2016-07 is no longer implemented using the calculation value ΔLw,R, but rather the “test stand value” ΔLw,P. Only at the end of the forecast after consideration of all the perimeter surfaces (flanking surfaces) involved in the transmission of sound is an element of forecast uncertainty included in dependence on the type of separating constructional component. For a transitional period both the test stand values and the calculation values used up to now will be stated in Knauf System Data Sheets.
Mechanical load performance Imposed loads Imposed loads are variable or movable effects on the building element (e.g. persons, furnishings and fittings, unloaded lightweight partitions, stored materials), which have to be specified by the planners in accordance with the intended usage. This System Data Sheet includes constructions for the standard specified imposed loads (load capacities). Knauf Pre-Fab Floor Screed systems are designed for example for residential and office areas as well as hotels and hospitals. Resistance to castors of chairs Brio elements, Brio composite elements and Vidiwall 1Mann are resistant to castors of chairs without additional measures.

Notes on fire resistance The specifications marked with offer additional application options, which are not directly included in the Certificate of Usability. On the basis of our technical assessments, we assume that these marked design solutions can be assessed as a non-significant divergence. We can make the documentation on which this assessment is based, such as surveyors' reports or technical assessments, available to you together with the Certificate of Usability on request. We recommend that a non-significant divergence be coordinated and authorised in advance in consultation between the persons responsible for fire resistance and/or the relevant authorities. The stated constructional and structural properties, and characteristic building physics of Knauf systems can solely be ensured with the exclusive use of Knauf system components, or other products expressly recommended by Knauf. The validity and up-to-datedness of the stated proofs have to be considered.
Pre-fab floor screed elements for drywall based screed systems Brio consists of homogenous gypsum fibre elements with milled rebates. Brio elements are 18 or 23 mm thick gypsum fibre boards in a format of 0.6 m x 1.2 m with milled 35 mm wide rebate. The elements are adhesively bonded in the notch area using two beads of Brio Joint Adhesive and then screwed or stapled together. Suitable for underfloor heating. Brio composite elements, thickness 18 mm, laminated with 10 mm wood fibre footfall sound insulation layer or with 10 mm mineral wool (total thickness 28 mm) / 20 mm polystyrene thermal insulation layer (total thickness 38 mm) or Brio elements, thickness 23 mm, laminated with 10 mm wood fibre footfall sound insulation layer (total thickness 33 mm).
Pre-fab floor screed is separated from the substrate on Schrenzlage synthetic coated kraft paper or an applied stable equalization layer to compensate for unevenness under the pre-fab floor screed.
Pre-fab floor screed on a separate insulation layer, as a composite element (Knauf Brio WF/EPS) or on light levelling mortar, to achieve fire protection, sound insulation, thermal insulation or a height equalization.
Pre-fab floor screed on underfloor heating with heating tubes underneath the screed (construction type B).

Additional measures required
On Knauf Pre-Fab Floor Screeds, the drywall partitions can be positioned with a load per unit length, which complies with the point load of the Brio + 2.0 kN, at every position on the floor without the need for additional measures.
Drywall partitions with a load per unit length of more than the value of the point load of the Brio + 2.0 kN can be installed after an increase in the load capacity of the pre-fab floor screed.
With loads greater than the previously stated expected loads of partitions or cantilever loads, the Brio supporting layer thicknesses must be increased and/or foundations with a higher load capacity must be installed.
It is beneficial to install the partitions directly on the basic floor due to the better sound insulation and stability of the construction.
It is recommended that partitions are not installed on pre-fab floor screed with underfloor heating due to temperature-based expansion.
Refer to the System Data Sheets of the individual Knauf partition systems for the specifications of the weights.
Data for planning Load capacity I Fire resistance
Data for planning Fire resistance
General notes on fire resistance The values in the following tables apply with single sided fire exposure from the top of the ceiling. The specified supporting layer thickness is the required minimum thickness for fire resistance. Larger screed thicknesses that are structurally necessary must be considered. The sequence of the layers as listed in the table as required for fire protection is absolutely mandatory. Intermediate layers permissible for fire resistance purposes, with the exception of sheet metal can be installed additionally between the necessary layers.
Non-combustible building materials for example are: Mineral fillers, Knauf boards (GKB/GKF/Vidiwall), Trockenschüttung PA dry bulk leveller.
Flammable building materials for example are: Wood fibre (WF or cementitious lightweight wood wool), ≤ 60 mm EPS/ XPS without/with FHS, EPO-Leicht.
Note
EPS/XPS is only permissible up to a total thickness of 60 mm; EPO-Leicht up to a total thickness of 80 mm (with trapezoid sheet metal the depths of the corrugations are not included).
≤ 5 mm separating layers for example are: Knauf Schrenzlage, Knauf Integral Auflagerdämmstreifen support insulation strips, Malervlies fleece layer, Wellpappe corrugated cardboard, PE foil.
Construction Brio should be aligned and applied with a minimum 500 / 200 mm joint stagger joint offset, joints and screw/staple heads must be filled with Uniflott.
Bonding of the rebates with Knauf Brio Joint Adhesive or Knauf Weissleim (PVA glue), fastening of the rebates with Knauf gypsum fibre screws or staples.
On trapezoid metal sheets with top spacing ≤ 100 mm, filling the corrugations with a stable and substantial material can be omitted.
Edge design Edge insulation strips: Building material class A, melting point ≥ 1000 °C, density ≥ 90 kg/m³ (e.g. Knauf Edge Insulation Strips made of mineral wool).
Layers above the base substrate Above Brio constructions with a fire resistance classification, either a thin-layer underfloor heating system (e.g. Uponor Minitec) with N 440 or alternatively and additional Brio board layer for accepting special cut heating pipe grooves can be installed.
Standard floor coverings such as Brio pre-fab floor screed constructions can be applied.
Floor constructions on trapezoiodal metal sheet Floor construction on trapezoiodal metal sheet with/without filled corrugations In case of application on trapezoidal metal sheet, the corrugations should normally be filled with a stable and substantial material or bridged with a suitable board
With Dry Bulk Leveller PA: min. 20 mm above top of trapezoidal sheets
≥ 20
With EPO-Leicht: Fill at least up to top of trapezoidal sheets
Cover trapezoidal sheets with a bridging wooden board or GIFAfloor (non- combustible)
On trapezoid metal sheets with top spacing ≤ 100 mm, filling or bridging the corrugations can be omitted.
Cover trapezoid metal sheet with fleece, glue on Knauf Integral Auflagerdämmstreifen support insulation strips
No insulation layers permissible between trapezoid metal sheet and pre- fab floor screed
Laying of the Brio elements laterally to the corrugations ≤ 100
Note The trapezoid metal sheets must have the necessary load capacity for the expected / planned loads at every point.

Data for planning Thermal insulation
Requirements on constructional components in case of remodelling/renovation acc. to EnEV 2014 – U value (W/m2K) Cellar floor insulation to the soil
Cellar ceiling insulation for an unheated cellar
Insulation of top storey floor slab for an non-converted attic
Insulation in heated area 0.50 unheated area 0.30
Insulation of the floor slab with new buildings is generally implemented as thermal insulation (perimeter insulation) underneath the floor slab. On old buildings the insulation is retrofitted above the floor slab. The composite element Brio 18 EPS and an additional thermal insulation layer made of EPS/ XPS can be used for quick and energy-related modernisation purposes.
It is recommended that the cellar ceiling be insulated to prevent heat transfer through a storey floor slab to an unheated cellar. On the top this can be implemented using the composite unit Brio 18 EPS. If insulation from above is insufficient, e.g. as not enough space is available, the bottom can also be insulated with insulation of the cellar ceiling (e.g. with products from Knauf Insulation).
Missing thermal insulation of the top storey floor slab to the unheated attic leads to high heat losses, and there is a danger of formation of condensation leading to moisture damage. Furthermore, a high room temperature may result in summer. In non-converted attics that are only conditionally walkable, insulation of the upper side of the ceiling (e.g. with products from Knauf Insulation) is prudent.

Details
Area of application Brio can be used in domestic bathrooms and kitchens, in bathrooms of hotel rooms or rooms with similar exposure to moisture. A sealant is required. Brio is not suitable for wet areas where slopes and drains are intended, (e.g. commercial kitchens, communal showers, swimming pools). Brio may be used in bathrooms with flush-to-floor (barrier-free) shower elements, if the shower tray is applied as a separate element complete with its own slope (see F127.de-V31). Shower elements also for subsequent installation. Sealing Apply Knauf Flächendicht or Knauf Flex-Dicht 1) to the entire surface. Execute the connections to the walls with Knauf Flächendichtband sealing tape. Joint between Brio and shower element – barrier free bathroom Seal the joint with a sealing strip and integrate into the area sealing of the pre-fab floor screed and shower element. Recommended area sealing is a suitable cementitious sealing slurry (e.g. Knauf Flex-Dicht1)). Insulation layers – barrier free bathroom EPS DEO (compressive strength ≥ 150 kPa) with footfall sound insulation use of wood fibre insulation max. 10 mm, e.g. wood fibre insulation board WF
Levelling For dynamic loads (e.g. washing machines), do not use Trockenschüttung PA dry bulk leveller, use Knauf EPO-Leicht. Use a rigid substrate leveller for the barrier free construction type, e.g. not the flexible light levelling mortar Knauf EPO-Leicht or the Knauf jointing compounds.

Installation and application Height equalization of the basic floor I Substrate
Height adjustment of the basic floor The surface must be sufficiently even – check the height! Pre-fab floor screed must be applied to the entire surface. Minor unevenness For levelling low height differences, use Knauf leveller and equalization compounds after application of a suitable primer.
Gypsum based leveller and equalization compounds: 0 – 10 mm N 410 3 – 10 mm N 410 Flex 2 – 30 mm N 430 10 – 40 mm N 430
Cementitious leveller and equalization compounds: 0 – 20 mm N 320 Sprint 3 – 20 mm N 320 Flex 0 – 30 mm N 330 Premium 5 – 40 mm N 340 2 – 40 mm N 340 Sprint
Wooden substrates Use corrugated cardboard or a felt base as levelling for minor unevenness on worn old floorboards and direct laying of the pre-fab floor screed without insulation layer.
Wooden substrates can be filled with N 410 Flex or N 320 Flex. Seal the joints and knotholes beforehand. Application of Knauf Spezialgrund primer is necessary.
Major unevenness Trockenschüttung PA dry bulk leveller (grain size 1 to 6 mm, weight per unit area approx. 5.5 kg/m² per cm height, residual moisture ≤ 1 %), leveller height 20 to 100 mm, from approx. 50 mm leveller height additional compression of the bulk leveller is required. To simplify the process, cover the bulk levellers with a Vidiwall 1Mann or Knauf Holzfaserdämmplatte WF wood fibre board; under the mineral wool insulation layer or underfloor heating, this covering is required and under EPS it is recommended. Trickling protection with Knauf Schrenzlage synthetic coated kraft paper is required on wood joist ceilings. Do not use Trockenschüttung PA dry bulk leveller on wooden plank stack slab ceilings. Dry bulk leveller may not be used in rooms subject to high dynamic loads (e.g. washing machines, tumbler driers).
With constant height adjustment or in case of installation tubes installed on the basic ceiling: Polystyrene EPS DEO or cementitious or magnesite bonded wood wool boards (EN 13168). Encase tubes with mineral wool, EPS or multi-layer wood wool slabs should be applied to the tubes accordingly.
EPO-Leicht is a quick-setting and water-free levelling mortar for layer thickness' of 15 to 800 mm with a weight per unit area of approx. 2 kg/ m² is walk-on-able after 24 hours. EPO-Leicht is used for levelling uneven floors and for filling cavities and height adjustment particularly where high dynamic loads occur (e.g. washing machines, tumbler driers). EPO-Leicht can also be used for concrete slabs underneath any necessary sealing required.
Substrate Check the substrate and any applied height adjustment layer (unevenness, height difference, load bearing capacity).
Ensure that there is a fully stable, load-bearing substrate made of planking or wooden composite boards together with wood joist ceilings (deflection max. l/300). No direct laying of pre-fab floor screed on wooden joists (only possible with the Knauf GIFAfloor LBS F191/F192). Application over dead floor and levelling with bulk leveller or EPO-Leicht only if sufficient bearing capacity of the dead floor is assured.
On reinforced concrete slabs, apply a cover of PE-Foil of least 0.2 mm thickness as protection against rising residual moisture from the floor that overlaps by at least 20 cm and up the walls to the height of construction.
On concrete slabs contacting the soil, apply sealing against ground moisture in acc. to DIN 18533 using Katja Sprint sealing membrane.
Apply 12 mm thick Knauf Mineralwolle-Randdämmstreifen mineral wool edge insulation strips for the connection to the walls.
Insulation layers: The technical specifications of the respective manufacturer apply as proofs of suitability.
In case of direct laying of Brio elements without insulation layer on the even or filled basic floor or on EPO-Leicht, apply painters fleece (side with foil pointing upwards), soft cardboard or similar to avoid clicking and rattling noises between Brio and solid ceiling when walking.
Laying on pre-fab floor screed Brio General Brio elements can be applied without joints as unheated constructions. Structural joints must be implemented in the screed. Lay the elements continuously in the door area or form butt joints underneath the door leaf and underlay with approx. 100 mm wide strips made of Brio elements or wooden material board strips ≥ 19 mm and adhesively bond with elements/boards (using Brio Joint Adhesive) and screw fasten. Lay the elements continuously, using the cut section from the previous row ≥ 200 mm to start the new row at an offset (no cut waste). In case of connections of pre-fab floor screed to other floor constructions (e.g. with flowing screed), provide limit or separating rails or movement joint profiles and pull the foil upwards. Precompact the dry bulk leveller well in the connection area. First wall connection element row Cut off the notch with connection to wall
Laying on a separating layer/insulating layer Start laying on the left of the wall opposite the door. The elements can be laid continuously in the door area (if butt joint at door area, please underlay) Laying on Vidiwall 1Mann Floating application with a joint stagger to Vidiwall 1Mann joints ≥ 200 mm. Full surface adhesive bonding is permissible. Laying on Trockenschüttung PA dry bulk leveller Start at the right when laying on the door side. Apply underlay to the element joint in the door area. It is recommended that the dry bulk leveller is covered with a covering board for saving time when laying the elements. In this case laying should begin at the wall opposite the door starting on the left.

Adhesive bonding + screw fastening / stapling Fixed, rigid connection by gluing and sealing the Brio element joint connections in the notch with Brio Joint Adhesive (2 beads of adhesive).
Alternatively, the notch can be adhesively bonded with Knauf PVA glue (Weißleim). The setting time is extended and you should not walk on the Brio directly after adhesive bonding. Laying starting at the door and into the room is not possible.
Fasten the Brio elements in the notch area with Gypsum fibre board floor screws SN, 17 mm (Brio 18) or 22 mm (Brio 23) long or using staples (spacing ≤ 300 mm).
When screw fastening/stapling the element to be fastened should have the body weight applied to it.

After laying the pre-fab floor screed using Brio Joint Adhesive, do not walk on the surface for about 4 hours, and when using PVA glue for about 8 hours (temperature dependent) to ensure that the adhesive can set properly.
Note
Protect the screed surface against building site traffic. It is highly advisable to apply the screed when all other work has been completed. For laying instructions refer to the Application Instructions F12LD.de

Heating floor screed Brio elements can be applied on underfloor heating. The installation of movement joints is recommended in doorways and when edge lengths exceed about 20 m. The flow temperature may not exceed 55 °C. Use of electrical underfloor heating or electrical temperature control of tiles is only suitable under certain conditions. A heat build up (e.g. under wardrobes, carpets) must be excluded. The screed element may not exceed a temperature of 45 °C at any point. For laying a thin-layer heated screed on pre-fab floor screed, refer to System Data Sheet FE22.de.
Note Protect the screed surface against building site traffic. It is highly advisable to apply the screed when all other work has been completed. For laying instructions refer to the Application Instructions F12LD.de
Installation and application Surface treatment and floor covering
Surface treatment and floor covering Board joints Fill the board joints with Uniflott if necessary. With fire protection from above, always fill the joints and screw heads and staples with Uniflott. Repairs Smaller holes and damage should be sealed with Uniflott. Larger holes and damage in pre-fab floor screed can be repaired with Knauf Stretto. The screed surfaces must be primed with FE-Imprägnierung impregnation agent for this purpose. Stretto is subsequently applied wet on wet. Protection against moisture in wet rooms On surfaces where water is expected in domestic bathrooms and kitchens, apply full surface sealant with Knauf Flächendichtband sealing tape. Resistance to castors of chairs Pre-fab floor screed Brio and Vidiwall 1Mann are resistant to castors of chairs without additional measures. Priming Before laying the floor covering and before full surface levelling, Brio and/ or Vidiwall 1Mann must be primed with Knauf Estrichgrund screed primer (diluted 1:1 with water) or Knauf Schnellgrund primer (undiluted). When applying parquet, apply a preliminary layer of system compliant adhesive. Elastic thin-layer floor coverings With elastic thin-layer floor coverings (e.g. PVC, Linoleum), Knauf Pre-Fab Floor Screed must have a full surface application of at least a 2 mm thick layer of N 410 applied. Fill the board joints beforehand with Uniflott and subsequently prime with a full surface application of Knauf Estrichgrund screed primer (1:1) or Knauf Schnellgrund primer (undiluted). Prefabricated parquet or mosaic parquet Multi-layer prefabricated parquet or mosaic parquet (chequered design) are suitable with full surface adhesive application on pre-fab floor screed. After consultation with Knauf or the adhesive manufacturer, e.g. Uzin Utz AG in Germany (Tel. +49 (0)731 / 40 97-0; www.uzin.de), other types of parquet can be laid. On a separating layer or with bracket mounting other types of parquet can always be used. Should Knauf Pre-Fab Floor Screed be levelled with N 410 before the parquet is laid, proceed as described in “Elastic thin-layer floor coverings”. Ceramic tiles and natural stone Use flexible adhesive systems. The processing requirements of the adhesive manufacturer for the tile size used, particularly the stated minimum thickness of the adhesive bed, must be observed, if necessary, install fabric or fleece. Lay stoneware and natural stone using the buttering-floating method, and push the tile with side motion into the adhesive bed while pressing it in. Lay floor tiles with a format of max. 33 cm edge length using the thin bed method. Large format floor tiles and natural stone can be laid on Knauf Pre-Fab Floor Screed up to 120 cm edge length. For more details see the load tables on pages 9 to 15.
