Kingspan Insulation Boards

Celotex PL4000 is an insulated plasterboard range from top insulation manufacturers Celotex. This is a 12.5 tapered edge plasterboard bonded to PIR insulation. Importantly this insulated plasterboard does not have a foil back the same as standard insulation. Celotex have designed a paper backed insulation board. This is a great design as this paper backed insulated plasterboard can be fixed using Drywall adhesive. Also advise when fixing this type of insulation is that you should always use a few mechanicl fixings as well. Alternatively you can fix this product with just mechanical fixings.


Celotex PL4000 comes in various thicknesses from 25mm to 65mm insulation factory bonded to 12.5mm plasterboard. The idea behind this product is that it provides a two in one product. This enables a quick installation with the builder being able to fix what would be two separate sheets in one. It is important to note that although this can be quicker it can also prove more expensive. An alternative solution could be installing a sheet of Celotex insulation and plasterboard and mechanically fixing through both. This alternative method only works if you do not want to dot and dab the boards to the wall as normal insulation has a foil back.
