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

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.
