Kay Metzeler expanded polystyrene EPS70 Insulation Boards
Kay-Metzeler EPS70 Floor insulation
EPS-70 can be used below the concrete slab in domestic
solid ground-floor constructions to satisfy the Building Regulations'
U-value requirements
EPS-70 can be fitted between or below the joists to
provide insulation to suspended timber ground floors.
EPS-70 can also be used below a sand/cement screed, above
either a concrete slab, precast suspended concrete floor or beam and
block floor system in domestic ground-floor constructions to satisfy
the Building Regulations U-value requirements. It can also be used in
conjunction with underfloor heating systems to reduce downward heat
loss.
Product Details
Type
Kay-Metzeler EPS-70 is supplied as EPS 70 as defined in BS EN 13163.
Dimensions
Standard size, 1200 x 2400mm. Thickness, 25, 50, 75, and
100mm
U-Values
The 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.
Low thermal transmittance
Thermal Value of 0.030 & 0.033 W/mK
Rapid construction
No specialised trades or equipment are required
All-dry construction
The use of EPS-70 with a chipboard finish provides an
all-dry method of construction, saving up to one week in site time
compared to a wet screed.
Permanent
EPS-70 is long lasting efficient thermal insulation which will remain effective for the life of the building. Performance does not deteriorate with age
Cost-effective
EPS-70 provides a cost-effective
solution to floor insulation.
Easy to handle
EPS-70 is manufactured from expanded polystyrene (EPS),
and is lightweight, easy to handle abd cut, and simple to install without the need of special tools
Approvals
EPS-70 has been assessed and approved by the British
Board of Agrément for use below flooring grade chipboard on a concrete
or precast ground floor; Certificate number 89/2196.
Product Specifications

Compressive Strength at 10% Compression (kPa) = 70
Cross Breaking Strength (Bending Strength) (kPa) = 115

Thermal Conductivity Value =0.038
Installation
The product is for use on ground-supported and suspended floors and may be installed on:
a concrete floor with a cement-based screed overlay; or
a concrete floor with wood based overlay board; or
hard core bases of ground floors with the concrete placed over.
It is used to reduce the thermal transmittance of new or existing floors.
In ground-supported concrete floors, the concrete floor slab over which the boards are laid
should be left as long as possible to maximise drying out and dissipation of constructional
moisture, in accordance with BS 8203 : 2001, Section 3.1.2.
The floor surface should be smooth and flat to within 5 mm when measured with a 3 m straight
edge. Irregularities greater than this must be removed. Minor irregularities (up to 10 mm) may be levelled with mortar.
The boards can be used on beam and block suspended concrete floors that are subject of a
current Agrément Certificate and installed in accordance with, and within the limitations
imposed by, that Certificate.
Where the boards are used over ground supported concrete floor slabs a suitable damp-proof membrane in accordance with BS 8102 : 1990 and CP 102 : 1973 should be incorporated to resist moisture from the ground. If a liquid-type damp-proof membrane is applied to the slabs, it should be of a type compatible with expanded polystyrene and be allowed to dry out fully before laying the boards.
Where the boards are used on hard core bases under ground-supported concrete slabs, the
hard core must be blinded before application of the boards.
Where a screed or concrete slab is laid over the product, vertical upstands of insulation should be provided and be of sufficient depth to separate fully the screed or slab from the wall and provide a minimal thermal resistance of 0.75 m2KW–1.
A suitable cavity or external wall insulation material can be extended below the damp-proof course level to a minimum of 150 mm below the top of the floor insulation to provide additional edge insulation.
Behaviour in relation to Fire
The boards do not prejudice the fire resistance properties of the floor.
When properly installed, the boards will not add significantly to any existing fire hazard. The
polystyrene boards will be contained within the floor by the overlay until the overlay itself is
destroyed. The boards therefore will not contribute to
the development stages of a fire or present a smoke or toxic hazard. Electrical cables running within the boards should be separated from it by enclosing them within a suitable conduit, eg rigid PVC.
Floor loading
The design loadings for self-contained dwelling units as defined in BS 6399-1 : 1996 are:
intensity of distributed load (kPa) <1.5
concentrated load (kN) <1.4
The boards covered with overlay board or screed, can support these design loadings without
undue deflection.
A BRE survey of imposed floor loading in domestic buildings (see BRE current paper No 2/77
Floor loadings in domestic buildings — the results of a survey) indicates that loadings in flats are
commonly in the region of 0.6 kPa and loadings of 1.5 kPa are normally associated with fixed items.
Where the boards are used under a concrete slab, resistance to concentrated and distributed
loads is a function of the slab specification.
It is recommended that with heavy, vibrating items, such as washing machines, the overlay is supported on timber battens of the same thickness.
Precast concrete floors
Where EPS-70 is used in precast concrete floor, care
should be taken that there is not excessive variation in level between
individual 2 conjunction with a suspended units. If EPS-70 spans
between high points, then a levelling screed or compound should be
used; the use of dry sand as a levelling medium is not satisfactory.
Moisture penetration
The boards are not a water vapour controlling layer; however, they will not allow moisture to
cross the completed floor construction.
9.2 For floors subject to national Building Regulations, construction should be as detailed or
designed in accordance with ...

Damp-proof membrane
EPS-70 should not be regarded as a damp-proof membrane
(DPM), and a suitable DPM must be used to protect floors in contact
with the ground. The membrane may be positioned either above or below
the concrete slab; see Figures 9 and 10. Liquid membranes are
positioned above the concrete slab.
If a liquid DPM is used, care should be taken that it is
compatible with EPS-70, and that it is completely dry before the
insulation is laid. Where the DPM is positioned below the concrete
slab, a vapour-control layer, of minimum 1000g polythene or equivalent,
should be laid over the EPS-70.
All edges should be overlapped a
minimum 150mm and taped, and the material should be turned up 100mm at
the perimeter and fixed behind the skirting.
