Table 1: Product Range

Quinn-Lite B3 is certified for use in theconstruction of internal walls, including use ininner leaf of cavity walls. The use of Quinn-Lite

B3 blocks below dpc level is not recommended. Itcan be used as a foundation block under thecontrol of an engineer after checking the soil forsuitability in respect of sulphates.

Quinn-Lite B5 and B7 are certified for use in theconstruction of loadbearing and non-loadbearinginternal and external walls above and below dpclevel, including use in inner and outer leaves ofcavity walls. If placing slabs on blocks, aminimum size of 150mm block is recommended,however approval must be obtained from anengineer to ensure the strength of the blocks willcarry the weight of the slabs.

When used below dpc level, includingfoundations, it is recommended that the mortarfor the laying of the blocks be 1:1:4cement/lime/sand.

For external build, Quinn-Lite Aircrete blocksmust be rendered using Weber.pral D render.Details of approved applicators must be obtainedfrom Weber Building Solutions Ltd.

Quinn-Lite B3, B5 and B7 are CFC and HCFCfree and therefore have zero ozone depletionpotential (zero ODP).

2.2 MANUFACTUREThe blocks are manufactured in accordance withthe test requirements of IS EN 771-3:2005Specification for masonry units Aggregate

concrete masonry units (dense and lightweightaggregates) and IS EN 771-4:2005 Specificationfor masonry units Autoclaved aerated concretemasonry units.

2.2.1 Quality Contro lQuality control checks are carried out on theincoming raw materials, during production and onthe finished product. These checks includecompressive strength, density and dimensionalaccuracy.

2.3 DELIVERY, STORAGE AND MARKINGThe blocks are supplied banded and shrink-

wrapped on pallets, with a label showing themanufacturers name, IAB identification mark andIAB Certificate number. Each block type has adifferent coloured band: yellow for B3, blue for B5and red for B7.

The blocks must be stored clear of the ground ona firm level surface and protected from saturation.The shrink-wrapping should be kept in place untilthe blocks are ready for use.

2.4 INSTALLATIONBedding Mortar Detail1:1:6 Cement/lime/sand mix must be used above

dpc level 1:4 cement/sand with plasticizer is tobe used for below dpc level. Moisten lime to forma lime putty before adding the cement and sand.A dash of mortar mix may be added. Ifnecessary, dampen the blockwork with a brushto overcome surface absorption before laying themortar. Alternatively other designation IIIreadymix mortar can be used as listed in BS5628-3:2005 Code of practice for the use ofmasonry Materials and components, designand workmanship.

LintelsSteel lintels are recommended when usingQuinn-Lite Aircrete blocks to prevent coldbridging. If full fill insulation is used in the cavity,concrete lintels can be used but metal lathingshould be placed over the face of the lintel(extending 300mm over each edge) beforeplastering. Concrete lintels can also be used overinternal doors.

External FinishThe external render must be Weber.pral D, usedwith a Weber.rend aid stipple coat. Thisrendering system must be applied on site bytrained approved applicators (see Section 2.1).

Chasing

In accordance with the Building Regulations1997 to 2006, vertical chasing in walls should notbe deeper than one third the thickness of the


4/13


wall, and horizontal chasing not deeper than onesixth the thickness of the wall.

Quinn-Lite Aircrete blocks are easily sawn,chased and drilled with standard tools. A discsaw is ideal for cutting tracks in the wall, and a

chisel is then used to remove the excessmaterial. Tools with hammer actions must not beused to remove excess material.

FixingsCut nails or spiral nails can be used forlightweight fixings. Figure 1: Cavity Wall Tie

Nylon plugs, suitable for hanging kitchen unitsand frame fixers, can be used for heavyweightfixings. Expanded metal fixings or plastic plugsare not to be used.

Not all standard fixings suitable for use with

dense aggregate blocks can be used in similarsituations with aircrete blocks. Quinn-Litetechnical department should be contacted forfurther information on fixings.

Movement JointsMovement joints to be used as per IS 325-2:1995The maximum recommended spacing ofmovement joints should be 5m and bed jointreinforcement should be used at window opes.

Temporary propping should be considered wherehigh walls are being constructed. It is advisableto prop gable walls and any long stretches of wallwhere return walls have not yet been built untilpermanent bracing is provided by the roofstructure.

Party WallsQuinn-Lite B5 or B7 blocks are suitable for use inparty wall construction. There are two types ofparty wall that can be used: a solid block 215mmthick, sheeted on both sides with 50mmMoyisover Calibel insulated plasterboard slab; ora cavity wall comprising two leaves of 100mmblock with a 75mm cavity between them, and50mm Moyisover Calibel board on the room sideof each leaf. The inner leaf of the perimeter wall(flanking wall) adjoining the party wall must also

be lined with Moyisover Calibel board. The partywalls and flanking walls should be plastered priorto the fixing of the Moyisover Calibel boardswhich should cover all areas, including thespaces between ceiling joists. No cut-outs forservices such as electrical plugs and switchesshould be made in the Moyisover Calibel boards.

Quinn-Lite B3 is suitable for use in theconstruction of internal walls, including use ininner leaf of cavity walls.

Part Four / Technical Investigations 4

4.1 BEHAVIOUR IN FIREQuinn-Lite Aircrete B3, B5 and B7 blocks have aClass 0 fire rating. The required thickness ofmasonry wall for a lightweight concrete block fora particular duration of fire resistance is given inTable 16a of IS 325-2:1995. The table shows thata Quinn-Lite Aircrete block has the sameperformance as a conventional dense aggregateblock.

4.2 PHYSICAL EFFECTS OF MOISTUREWhen used externally, the blockwork shall berendered as detailed in Part 2 of this Ceritifcate inaccordance with IS EN 13914-1:2005 Design,

preparation and application of external renderingand internal plastering External rendering. Theadvice of IS 325-2:1995 should be followed inrespect of exposure analysis and building details.

4.3 SOUND INSULATIONThe sound insulation of Quinn-Lite B5 and B7used in party wall construction (as detailed inPart 2 of this Certificate) have been assessedand shown to be in compliance with Part E of theBuilding Regulations 1997 to 2006.

4.4 THERMAL INSULATIONThe thermal conductivities of Quinn-Lite B3, B5

and B7 are shown in Table 1. Typical U-valuesare shown in Table 2, calculated in accordancewith Part L of the Building Regulations 1997 to2006.

4.5 CONDENSATIONCalculations in accordance with BS 5250:2002Code of practice for control of condensation inbuildings, show that the level of insulationprovided by the Quinn-Lite block masonry wallswith Weber.pral D render externally and 13mmlightweight plaster internally should minimise therisk of surface or interstitial condensation in allnormal environments in dwellings. As with all wallconstruction, care must be taken when installingthe dpc below windows to ensure that anycondensation occurring on the window is drainedoutwards.

4.6 DURABILITYBuildings constructed using Quinn-Lite B3, B5and B7, when constructed in accordance with themanufacturers instructions and the requirementsof this Certificate and all relevant codes ofpractice, will have a design life of60 years inaccordance with BS 7543:2003 Guide todurability of buildings and building elements,products and components. Buildings based onthe manufacturers recommendations, provided

they are properly erected and that construction iscarried out properly and accurately, should givegood performance under all relevant headingsthroughout their working life.
