116mm Celotex TD4000 provides a quick and easy way to achieve effective thermally insulated flat roof decks for building structures such as small extensions or garage roofs where there will only be occasional trafficking.
TD4000 features a foil faced rigid PIR (polyisocyanurate) board, to give the best insulation value possible, bonded to a facing of 5.5mm WBP exterior grade plywood. This allows the user to install the roof structure in one operation since the product provides the deck, insulation and vapour control layer thereby considerably reducing installation times ahead of weatherproofing.
Boards are manufactured using blowing agents that have zero ozone depletion potential (ODP) and low global warming potential (GWP).
Celotex TD4000 is purpose designed for use in light traffic flat roof applications:
