What does PIR stand for in insulation?
polyisocyanurate
PIR (polyisocyanurate), typically cut into boards, can be used in insulated metal panels, wall cavities and as insulated plasterboard. PIR has such a high thermal performance, it requires only half the thickness of other mineral-based insulation products. PIR, like PUR, is known for use as a low-moisture barrier.
Is 50mm insulation enough?
With 50mm of insulation you should expect to see a reduction in your heating bills by around 30%, but with 100mm that percentage will shoot to over 50%. Your heating system won’t have to work as hard, and as a result won’t use as much gas – so more cash in your pocket!
How thick should PIR insulation be?
Three types of PIR Insulation Boards available in different thicknesses, 12mm-45mm, 50mm-100mm and 110-150mm, all especially designed to eliminate thermal bridges, very easy to cut and shape and energy-efficient.
What is Recticel made of?
Recticel PIR rigid insulation products are composed of a polyisocyanurate foam core with a closed cell structure. They deliver a high thermal performance, contributing to a substantial energy saving in building projects and in turn increasing the comfort of the end user.
Can you use a jigsaw to cut Celotex?
I have so far cut and fitted 80 1200×2400 sheets of celotex on my own,and to be honest, the dust drove me mad. That’s why i experimented,and am now using a jigsaw with the above mentioned toothless,’knife blade’! Works a treat.. virtually dust free!
Do you need a mask when cutting Celotex?
Cutting and drilling insulation boards will release dust. Inhalation of dust may cause respiratory irritation and other health conditions. Any such activity should be carried out in a well-ventilated area, wearing a dust mask and safety glasses.
Does insulation Board need an air gap?
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.
How thick should loft insulation boards be?
One popular method is to install a 100mm thick layer of insulation between the joists in your loft, and then adding a layer of 170mm insulation at right angles over the joists to get the total thickness to 270mm.
How good is 50mm insulation?
Well obviously the thicker the insulation the greater the savings, so 100mm of insulation will provide bigger energy savings than 50mm of insulation. With 50mm of insulation you should expect to see a reduction in your heating bills by around 30%, but with 100mm that percentage will shoot to over 50%.
What U value does 50mm Celotex?
Technical Spec
| Product Code | Board dimensions (width) x (length) = (m²) | U-value (W/m²K) |
|---|---|---|
| Celotex CW4040 | 12×0.45×1.2 = 6.48m² | 0.56 |
| Celotex CW4045 | 11×0.45×1.2 = 5.94m² | 0.50 |

| Celotex CW4060 | 8×0.45×1.2 = 4.32m² | 0.37 |
Is Recticel as good as Kingspan?
All of the Above hold the same thermal conductivity on 100mm Insulation Board of 0.022W/mK. Contrary to popular belief all of these brands work towards the industry standard of 0.022W/km. So, no matter the PIR insulation brand either Celotex, Recticel, or Kingspan they all do the same job.
Is Recticel insulation waterproof?
Is Recticel Insulation Water Resistant? Moisture and dampness can significantly reduce the effectiveness of thermal insulation. Recticel have, therefore, developed their range of boards to withstand moisture from ground level or in an attic space.
