Technical supportVencel Resil provides technical and
design support and has a dedicated
team of professionals who have
extensive experience of working in the
industry. Many clients find the technical
support they receive invaluable in
ensuring that specifications are in line
with modern building requirements.
Being more than just a manufacturer of
EPS products, it is the company’s
expertise within this sector and the
knowledge within its team which
establishes Vencel Resil as one of the
leading providers of high performance
insulation.
Jablite – a market leadinginsulation materialVencel Resil has a major UK
manufacturing base, where its Jablite
expanded polystyrene products can be
produced to specific grades and
thicknesses to suit clients’ needs. As
such, the company is constantly seeking
ways to enhance the performance of the
range. Jablite EPS is a proven insulation
material, widely regarded as one of the
most effective on the market, offering
high thermal performance, unrivalled
sustainability credentials, long-term
durability, whilst ensuring its cost
effectiveness in the market.
Jablite PremiumJablite Premium is an innovative Low
Lambda (EPS) insulation material that
has the capacity to enhance a building’s
thermal performance by up to 20%. This
enables builders and contractors to meet
ever tightening Building Regulations
without having to change their build
practices
A relatively new innovation in EPS
insulation, Jablite Premium is becoming
widely used in the floors, walls and roofs
of domestic, public sector and
commercial buildings. Instantly
recognisable by its distinctive grey board
with orange speckles, it provides the
reassurances to architects, specifiers and
contractors that the material used on
site is the same as the one specified and,
crucially, that the resulting performance
matches the approved design intent.
A major benefit of Jablite Premium is
that it offers improved U-values without
having to alter the thickness of the
cavity wall or change the construction
of the floor or roof. This ensures
contractors on site maintain their
efficiency, whilst clients benefit from
maximum internal floorspace and low
running costs.
Vencel Resil is one of the UK’s largest manufacturer’s of expanded
polystyrene (EPS) and under the Jablite brand, supplies a range of
bespoke insulation products and solutions to the construction,
industrial and housebuilding markets. Vencel Resil specialises in
providing industry-leading insulation solutions that meet current
and future Building Regulations requirements for the
specification of floors, walls and roofs of commercial, public
sector and residential buildings.
Established in 1973, the company has been a member of the Synbra Group since
1996. Synbra is a multi-national organisation specialising in producing high quality
EPS products throughout Europe. Being part of a European group means having the
benefit of access to extensive resources and technology.

BRE Green Guide toSpecification The Green Guide, produced by the
British Research Establishment (BRE),
assesses a range of building
products’ environmental
performance over their full life-span
and awards them with a
sustainability rating.
EPS has achieved an A+, which is the
highest rating possible and clearly
demonstrates the material’s
excellent thermal and environmental
credentials. The BRE ranks materials
on the basis that the benefit of using
any of the insulation types listed in
the guide will outweigh
the embodied environmental impact
of their manufacture, installation
and end-of-life disposal.
Environmental credentialsExpanded polystyrene is recognised
for its excellent energy efficiency
and low environmental impact.
It has an ODP (Ozone Depletion
Potential) of zero and a low GWP
(Global Warming Potential), which is
exemplary. Vencel Resil is fully
committed to sustainability in all
areas of its operation. Energy saving
and modern methods of
construction are all carefully
considered when researching and
developing new products, as well as
end of life recyclability.

Jabfloor Premium insulation can be used in all floor constructions for both domestic and
commercial buildings. The application will determine the grade of Jabfloor Premium
required for your project. Jabfloor Premium 70 is mainly used for domestic floors, whereas
Jabfloor Premium 100 is widely used for commercial floors where higher loadings are
likely to be encountered.
Products: Jabfloor Premium 70 and 100
Jabfloor PremiumJabfloor Premium 70 and 100 can be used
below the concrete slab in solid ground-
floor constructions to satisfy the relevant
U-value requirements.
Easy to handleJabfloor Premium is manufactured from
expanded polystyrene (EPS) which is
lightweight and easy to handle on site
PermanentJabfloor Premium is rot-proof and durable
and will remain effective for the life of the
building. It also has the added advantage
of being flood-proof.
Rapid constructionNo specialised trades or equipment are
required.
VersatileJabfloor Premium can be used above or
below the damp-proof membrane.
EnvironmentExpanded polystyrene has been awarded
an A+ rating by the BRE’s Green Guide to
Specification.
TypeJabfloor Premium is supplied as EPS 70 and
100 as defined in BS EN 13163 – Reaction
to Fire Class E, containing a flame-
retardant additive.
ApprovalsJabfloor Premium has been assessed and
approved by the British Board of Agrément
for use below the concrete slab in solid
ground floors; Certificate number 87/1796.
DimensionsStandard size: 2400 x 1200mm.
Standard thicknesses: 25, 30, 40, 50, 60,
75, 100, 120, 150 and 200mm
(Other thicknesses available to order)
FireSolid ground floors are not required to
provide fire resistance. When properly
installed, Jabfloor Premium is fully
protected by the concrete slab, and will
have no adverse effect on the fire
performance of the floor.
U-valuesThe rate of heat loss through a ground
floor varies with its size and shape. The
thickness of insulation required to meet a
given U-value will similarly depend on the
size and shape of the floor. Approved
Documents L1A , L1B, L2A and L2B guide
you to BS EN ISO 13370 as the method
for determining floor U-values based on
the floor perimeter and floor area where:
“P” is length of exposed perimeter in
metres and “A” is floor area in square
metres.
The measurement of both the floor area
and perimeter should be made on the
internal finished surface of the walls
enclosing the heated space; unheated
areas such as garages, porches and storage
spaces need not be included. For buildings
such as terraces or blocks of flats and
apartments, the measurement should be
taken over the total gross
ground-floor area.
Table 1.1 shows the required thicknesses of
Jabfloor Premium 70 and 100, to meet
U-values of 0.25, 0.22, 0.20, 0.18, 0.15 and
0.10W/m2K. These values are based on the
following k-values:
Jabfloor Premium 70 0.030W/mK
Jabfloor Premium 100 0.030W/mK

INSTALLATION
Damp-proof membraneJabfloor Premium should not be regarded
as a damp-proof membrane (DPM).
A suitable DPM must be provided,
positioned either above or below the
Jabfloor Premium, or on top of the
concrete slab; (See figures 1.2 – 1.4).
Liquid membranes are positioned above
the slab. The hardcore should be blinded
before receiving either the Jabfloor
Premium or the DPM. If a liquid DPM is
used, care should be taken that it is
compatible with the Jabfloor Premium and
that it is completely dry before the
insulation is laid.
Jabfloor PremiumJabfloor Premium should be loose-laid over
the prepared surface; all joints should be
tightly butted. If the concrete slab is to be
poured directly onto the Jabfloor Premium,
the joints should be covered with
75mm-wide adhesive tape to prevent the
ingress of concrete or grout between the
boards. Vertical upstands of Jabfloor
Premium edge strip should be used around
perimeter to prevent cold bridging, as
detailed in BRE Report 262.
Concrete slabThe concrete slab is laid to the required
thickness and either tamped or power-
floated to provide the required finish.
During these operations, the surface of
Jabfloor Premium or the DPM should be
protected from impact damage or
excessive trafficking by the use of
spreader boards.
