Can you dot and dab Celotex PL4000?
Celotex PL4000 (replacing the PL3000 range) insulated plasterboard is made by bonding a layer of PIR insulation to a standard, tapered edge wallboard. As the insulation has a tissue face it is suitable for ‘dot and dab’ application but can also be mechanically fixed providing the appropriate fixings are used.
Does Celotex stop damp?
The vapour barrier is key as it stops moisture in the warm air in the habitable areas getting through to the cold side of the insulation and condensing. The combination of foil faced celotex with taped joints and foil backed plasterboard should give a continuous vapour barrier.
Why is insulated plasterboard so expensive?
The disadvantage of this insulation is that it is very expensive. This is due to the process involved in bonding the two types of material together. Another advantage is the face on the insulation is paper so it can be dot and dabbed for speedy instalaltion.
Can I stick plasterboard to Celotex?
Try using Everbuild Dry Fix it’s magic! You squirt the stuff on the back of the plaster board around the edges and across the centre, leave for 5 minutes and then press the board onto the Celotex. Make sure the the board surface is Celotex surface is dust free.It sticks like you know what.
Why does Celotex have foil?
The foil reduces heat loss through radiation. The glass fibre reduces heat loss through conduction. The foil side theregore goes where the temperature difference is greatest, that is it should face the space between the ceiling and the roof.
Does insulated plasterboard need an air gap?
Insulating a wall internally first needs to take into consideration whether the wall is a cavity wall or a solid wall. Insulation with a moisture barrier means you don’t need to leave an air gap during installation.
How thick should insulated plasterboard be?
60mm thick
Rigid insulation boards Plasterboard backed with rigid insulation is fitted to the inside of your walls. The insulation is usually made from one of several forms of foamed plastic. It should normally be at least 60mm thick, and can be up to 100mmm.

What can Celotex pl4000 be used for?
Celotex PL4000 is purpose designed for providing thermal insulation and plasterboard as one product. PL4000 can be specified for use in a variety of applications including: The ‘underneath’ layer of insulation in between and under rafter and joist applications. Solid masonry walls. Timber frame lining applications.
Can a Celotex partition wall be insulated?
The pre-existing insulation will contribute overall to the thermal performance of your build and the insulated plasterboard can be combined with further insulation in the partition wall. Celotex PL4000 is a tapered edge insulated plasterboard that can be installed using both dot and dab bonding as well as mechanical fix.
How big is a Celotex thermal laminate board?
The Celotex PL4000 thermal laminate comes in a variety of thicknesses ranging from 25mm to 65mm Celotex. The PL4000 provides excellent thermal performance. The Celotex boards are light and rigid making transport, handling, and installation easy.
