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

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,

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.

APPLICATION:Wall insulation – internal wall

Jablite Premium board is suitable for insulating the internal face of all types

of external wall construction, and can be used either in conjunction with

12.5mm plasterboard, or as the insulation part of a proprietary laminate.

Product: Jablite Premium Board

Jablite Premium boardJablite Premium board is available in a

range of thicknesses for use in different

wall-lining systems. It is an economical

method of providing good thermal

insulation and of reducing heating costs.

Walls which have been internally insulated

with Jablite Premium board respond rapidly

to heat input and good standards of

comfort are readily obtained. In buildings

which are only heated intermittently, the

risk of surface condensation is minimised.

Easy to handleJablite Premium board is manufactured

from low lambda expanded polystyrene

(EPS), which is lightweight and easy

to handle.

PermanentJablite Premium board is rot-proof and

durable and will remain effective for the

life of the building; the recommended

fixing methods will retain the boards

permanently in position. It also has the

added advantage of being flood-proof.

Easily cut to fitIf required, boards can be easily cut to

length using a sharp knife. No specialised

trades or equipment are required. Although

this technique is commonly used to

upgrade existing buildings, it is equally

applicable to new build.

EnvironmentExpanded polystyrene has been awarded

an A+ rating by the BRE’s Green Guide to

Specification.

TypeJablite Premium board is supplied as EPS

70 as defined in BS EN 13163 – Reaction

to Fire Class E, containing a flame-

retardant additive.

DimensionsStandard size: 2400 x 1200mm

Standard thickness: 25, 30, 40, 50, 60, 75,

and 100mm.

FireJablite Premium board is manufactured

containing a flame-retardant additive.

When properly installed, the insulation is

protected by the plasterboard (or other)

lining and will have no adverse effect on

either the surface spread of flame rating or

the fire performance of the wall.

Thermal ResistanceThe thermal resistance, R-value, of

Jablite Premium board for a range of

common thicknesses is as follows:

25mm 0.83m2K/W

30mm 1.00m2K/W

40mm 1.33m2K/W

50mm 1.67m2K/W

60mm 2.00m2K/W

75mm 2.50m2K/W

100mm 3.33m2K/W

Water vapour transmissionJablite Premium board has a significant

resistance to the passage of water vapour,

but should not be regarded as a vapour-

control layer. The risk of interstitial

condensation can be reduced by placing

a vapour-control layer between the

Jablite Premium board and the

plasterboard facing.

U-valuesTables 20.1 – 20.6 show a selection of

common wall constructions using a range

of materials and give the U-values

achieved according to the thickness of

Jablite Premium board used. The values

given are based on a k value of

0.030W/mK for the insulation.

INSTALLATION

Figures 20.2 – 20.4 show typical methods

of installing Jablite Premium board.

Single layer of JablitePremium board Treated timber battens should be attached

to the wall surface at appropriate centres

to suit the plasterboard. The size of the

battens and the method of fixing should

always be in accordance with the

plasterboard manufacturer’s instructions.

The Jablite Premium board is tight-fitted

between the battens. If the plasterboard

does not incorporate a vapour control

membrane, then a separate vapour-control

layer, consisting of a minimum 1000g

polythene, should be placed over the

insulation, and the edges and joints sealed.

Finally, the plasterboard should be fixed to

the battens in accordance with the

manufacturer’s instructions, and finished

as required. (See figure 20.2).

Double layer of JablitePremium boardThe method of installation is generally as

described above for a single layer system

but a second layer of Jablite Premium

board is fixed across the battens, taking

care that the joints do not coincide. These

boards should be pinned to the battens.

The vapour control layer should be placed

between the plasterboard and the second

layer of insulation. (See figure 20.3).

Composite boardsThe manufacturers of proprietary

EPS/plasterboard and other EPS insulated

composite boards have developed a range

of adhesive and mechanical fixing systems

for their products, and their

recommendations should be followed.

(See figure 20.4).

Further information on manufacturers and

suppliers of these products is available

from Vencel Resil's technical department.

Vapour-control layerJablite Premium board should not be

regarded as a vapour-control layer. The risk

of interstitial condensation can be reduced

by placing a vapour-control layer between

the Jablite Premium board and the

plasterboard facing, or by using

plasterboard which incorporates an

integral vapour-control membrane.

Solid-wall constructionsRegardless of the method chosen for fixing

Jablite Premium board, if the underlying

structure consists of a solid, rather than

cavity wall, a cavity should be provided

between the wall and the insulation in

accordance with the requirements of

Building Regulations Approved

Document C, Section C4.

ServicesService runs should be fixed before the

lining is installed. Any chasing for services

should be made in the wall itself and not

into the insulation. Jablite Premium board

should not be allowed to come into direct

contact with PVC-sheathed cable, nor

closer than 12mm to hot-water pipes;

cables should be protected by the use of a

physical barrier, for example by being

enclosed in a conduit.

ReferencesBuilding Regulations Approved Document C, Sections 5.10 and Diagram 11.

BS EN 13163 Thermal insulation products for buildings – Factory made products of expanded polystyrene (EPS) – Specification


Choice of insulationthicknessIn most cases, the use of a single layer of

insulation fitted between battens will not

provide a U-value which satisfies the

Building Regulations, and the use of a

second layer of Jablite Premium board,

fixed over the battens, rather than

between, can be used to improve the

insulation value to an acceptable level.

(See tables 20.1 – 20.6).
