Product Description

Celotex Tuff-R, with its low emissivity foil facings, is ideal for pitched and flat roofs, solid masonry walls, timber or steel framed systems, and floors.
Celotex Tuff-R is a multi-purpose rigid polyisocyanurate foam (PIR) thermal insulation board with reflective foil facings. provides multi-purpose cavity wall insulation boards that are uniquely reinforced with glass-fibre and feature the best reaction-to-fire performance measured in accordance with new European Standards of any PUR / PIR (Rigid polyurethane / polyisocyanurate) product on the UK market

Where Celotex Extra-R XR4000 should be used

This thicker version can be used in any rafter or joist application where there is the need to achieve improved u-Values from those available from a thinner board.

Celotex Extra-R XR4000 between rafters Insulation between rafters:

Celotex XR3000 between rafters

Use Celotex Extra-R XR4000 high performance thermal insulation in pitched roofs either between and under rafter or between the rafter applications to minimise insulation thickness and give the following benefits ...

Ideal for use where headroom is limited

Provides reliable long term energy savings for buildings

Low emissivity foil facers give improved thermal insulation with cavity air spaces

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

Ideal for loft conversions/room in roof applications

 

The void created by a pitched roof can be made habitable by insulating along the plane of the roof pitch with Celotex rigid PIR insulation boards. This creates a warm, potentially habitable roof space in which water pipes and tanks no longer need to be insulated.

If BS 747: 2000 slater's felt is being used, a minimum 50 mm ventilated air space must be provided between the felt and the cold side of the insulation in order to minimise the risk of condensation formation. This construction is known as a ventilated construction.

With some breathable membranes, the cold side of the insulation may be placed in direct contact with the membrane (check with membrane supplier prior to specification). However, the outer side of the membrane must be adjacent to an air space to allow moisture vapour to escape to the outside of the building. This is known as an unventilated construction.

Insulation for timber frame wall lining:

Timber frame wall lining with Celotex Rxtra-R

Celotex Insulation for timber frame wall lining Celotex utilises the low lambda values of Celotex tuff R GA4000 and ExtraR XR4000 between the studs, followed by an internal lining of Celotex T-Break TB4000 over the studs, providing for a thin build-up with the excellent thermal insulation.

Benefits:

Offers the thinnest solution available Provides reliable long term energy savings for buildings
Low emissivity foil facers give improved thermal insulation with cavity air spaces Provides a vapour control layer when board joints are taped
Reduces thermal bridging through studs and rails
Can be nailed direct to stud framing
Dryline directly over insulation
Provides cavity for services Installation guidelines
Suspended timber floor insulation

Fixing floppy quilt insulation between floor joists can be difficult. Insulating a suspended timber floor is made easy using Celotex Insulation cut to fit between joists.

The specification of insulation for ground floors is more complex than that for walls or roofs. This is because the mechanisms for heat flow are affected by the ratio of surface area to perimeter.

With a suspended timber floor, there is little choice but to install the insulation between the joists, but the thermal bridges created by the joists have to be considered.

Continuity of the insulation must be ensured by packing the spaces between the external walls and the joists with insulation. The void below an insulated suspended timber floor must be well ventilated. The insulation must be cut to fit tightly between the joists to prevent heat loss.

Installation:

Make sure all studs and rails are flush, with no projections, and that services are correctly installed.

Cut Celotex Extra-R XR4000 to fit tightly between all studs and rails.

For optimum thermal performance, the unprinted foil surface should face the air cavity.

Insert insulation into framing and push back to plywood sheathing.

Fit services in to cavity if required.

Measure the wall height from floor level to underside of ceiling joists and cut board length to suit, using a trimming knife.

Ensure that the wall insulation is continuous with the floor perimeter insulation.

Cut boards for infill panels, using off-cuts where possible, making sure there are no gaps at wall abutments.

Tightly butt edges of boards together, making sure there are no gaps.

Temporarily secure the boards with clout nails at 600 mm centres. Mark stud lines on board surface as fixing guides for dry lining.

Always fix back to solid timber, both at stud lines and at top and bottom rails.

Ensure that all board surfaces are clean and free from dust and then apply aluminum foil vapour-seal tape to all joints. Taping the joints of the Celotex insulation with self adhesive aluminum foil tape provides a good vapour control layer and improves air tightness.

Seal the insulation at all abutments and service penetrations with a vapour resistant sealant.

Fix plasterboard lining over the Celotex insulation using plasterboard nails or screws of appropriate length and joint or skim to the desired finish.

No separate vapour check membrane is required in this application; Celotex insulation acts as an effective internal vapour control layer when all joints are sealed. Suspended timber floor insulation Celotex
