What is Celotex TB4000?
Celotex TB4000 is a multi-purpose insulation board developed to provide simple solutions for overcoming localised thermal bridges. With low emissivity foil facings, TB4000 is manufactured from rigid polyisocyanurate (PIR).
How thick should Celotex be?
Available in a range of thicknesses, it can be used in rooves, walls and floors and achieves an A+ rating on the BRE Green Guide. The Celotex PL4000 Insulation Board is bonded to tapered edge plasterboard and has thicknesses available between 15 and 65mm.
What is Celotex board used for?
Celotex is a multi-purpose insulation board that can be used around the home for insulating roofs, walls and floors and they come in a range of sizes and thicknesses.
How long does Celotex last?
Once installed, if left unmolested and undisturbed we can say that the insulation will perform for the expected lifespan of the building into which it is installed, which is generally taken to be 60 years.
What is the thinnest insulation board you can buy?
OPTIM-R is Kingspan’s thinnest insulation. It comprises a rigid vacuum insulation panel (VIP) with a microporous core which is evacuated, encased and sealed in a thin, gas-tight envelope which gives an outstanding thermal conductivity of 0.007 W/m.K.
What is the thinnest Celotex you can buy?
TB4000
The thinnest product manufactured by Celotex, TB4000 is a high performance, rigid polyisocyanurate (PIR) insulation board specifically designed to address thermal bridging and reduce localised heat losses.
Does Celotex require an air gap?
Batten gap between bottom of celotex and plaster board. if the airflow is correct you won’t need foil back plasterboard. sometimes you can getaway with less celotex it depends on how strict the building control officer is. Of course this will have a negative effect on your heat loss and heating bills.
Do you need an air gap for insulation?
Solid walls, however, must be faced with an insulation product, so they can often eat into floor space depending on the thickness of the insulation as an air gap is needed to prevent condensation and moisture build-up. Insulation with a moisture barrier means you don’t need to leave an air gap during installation.
Is Celotex structural?
Celotex Blue Ridge™ Fiberboard, also referred to in its product literature as SturdyBrace® is a wood fiber product that is described by the company as: SturdyBrace® meets national codes for structural integrity. The insulating exterior wall sheathing is competitively priced. You may bid with confidence year round.
Is Celotex good for soundproofing?
The short answer is no. We often get asked if products used for thermal insulation (the likes of Kingspan or Celotex) will also be effective at soundproofing.
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.
