Technical Specification
Celotex Tempcheck Deck TD4000 comprises a polyisocyanurate rigid foam insulation core with low emissivity aluminium foil facings on both sides bonded to a layer of 5.5mm WBP exterior grade plywood.
Celotex TD4000 is CFC/HCFC free with zero ODP and low GWP. CE marking compliance to BS EN 13165:2001 and manufactured in accordance with quality management systems with BS EN ISO 9001:2000 by Celotex Limited.
All products must be installed in accordance with instructions issued by Celotex Limited.
Where Celotex Tempckek Deck - TD4000 should be used
Ventilated lead covering
Use Celotex TD4000, (or Celotex GA4000 or Celotex XR4000) in ventilated, lead covered, warm roof applications to minimise insulation thickness and give the following benefits: Provides reliable long term energy savings for buildings Ideal for use in occasionally trafficked applications Warm roof construction due to over joist installation Rapidly installed and weatherproofed Celotex TD4000 provides deck, vapour control layer and insulation as a three-in-one product Celotex XR4000 provides the thickest insulation available in the market allowing even lower U-values to be achieved.
Flat roof insulating deck
Use Celotex TD4000 to combine high performance thermal insulation with 5.5mm WBP ply for use in flat roof deck applications to minimise insulation thickness and give the following benefits: Three-in-one product to provide deck, vapour control layer (VCL) and insulation Provides reliable long term energy savings for buildings Ideal for use in occasionally trafficked applications Warm roof construction due to over joist installation Rapidly installed and weatherproofed Accepts a wide variety of weathering systems.
Loft conversions
 Use Celotex TD4000 high performance thermal insulation in loft conversions to minimise insulation thickness and give the following benefits: Ideal for use where headroom is limited Provides reliable long term energy savings for buildings Creates a warm, habitable roof space No need to insulate water pipes and tanks Suitable for new build and major refurbishment projects Minimised additional loading to the structure.
Installation Guidelines
Celotex Tempchek TD4000 products must be installed in accordance with these instructions
Ensure that joist spacing is at no more than 600mm
centres and that the dimension of the joist is sufficient to
span and accept additional loads. If asphalt weathering is
to be used, joists should be at no more than 400mm
centres.
Install the insulation boards, ensuring that the long edges are parallel to the line of the joists. 50mm x 50mm
cross noggings should be inserted between joists to
support the short edges of the boards.
Where boards butt together, bed onto twin beads of
vapour sealant wide enough to accommodate this
arrangement. This completes the vapour control layer
(VCL) when combined with each board’s foil facings.
Lay the boards with the plywood side uppermost and
stagger board joints. Leave a gap of approximately 2mm
between boards and ensure a minimum 20mm bearing
on joists and noggings.
Fix Celotex TD4000 with corrosion-proof Sure twist
Composite Panel helical fasteners at a frequency to suit
the design wind load. Refer to BS 6399-2 Code of Practice
for Wind Loads. As a guide, 16 fasteners per board will
resist a wind load of 2.22 KN/m2 based on a design load
of 0.4 KN per fastener.
Ensure that fixings are no less than 10mm in from the
board edge or 50mm from each corner. They should be
equally spaced along the supporting joists. Fixings
should be long enough to penetrate at least 38mm into
the supporting timber.
Stagger opposing fixings where two board edges
share the same joist or noggin.
Provide a complete insulation envelope by extending
the wall insulation board up to the underside of the roof
deck.
Provide a soffit or ceiling below the joists, as the
surface of the product is not designed to be used as a
decorative internal finish.
Ensure that the plywood is completely dry before any
weathering system is applied.
Always use a Type 3G felt to BS 747 as a vapour
diffusion first layer when using BUR weathering systems.
When using a single-ply membrane, additional 12mm
plywood has to be applied on top of the Celotex TD4000.
Temporary protection must be provided for both the
insulation and the waterproofing, if significant foot traffic
is anticipated either during or after installation.
Falls
The structure should be designed so that the finished roof has a continuous, smooth and even slope towards the rainwater outlet or gutter. The minimum fall should
be 1:80 to avoid pounding water.
Deck stability
Celotex TD4000 incorporates exterior grade WBP plywood to BS 1203, laminated to the surface. This gives the product excellent strength. Boards can span
up to 600mm joist centres to provide a suitable
substrate for a variety of weathering systems.
Vapour control layer
Celotex TD4000 has a built-in VCL due to the foil facers
but this is discontinuous at the board joints. In some applications no further attention to moisture control may be necessary. Celotex would generally
recommend the application of a vapour sealant between the tops of the boards at all edges. This is
essential in areas of potentially high humidity.
U-Value - a definition
U-value (or thermal transmittance co-efficient) is a measure of how much heat will pass through one square metre of a structure when the temperatures on either side of the structure differ by 1 degree Celsius (expressed in W/m2K)
