Ballytherm Insulation is a Polyisocyanurate (PIR) insulation board with foil facing on each side. The PIR board is formed by a continuous foaming process which gives the board its tight cell structure and bonds the facing to the foam. After foaming, the boards are cut to size and left to cure.

Ballytherm is well suited for use in areas where damp can occur like basements. Ballytherm insulation boards are fire resistant and can remain at stable temperatures up to 400ºc, a protective char will then form on the boards to slow down the spread of flames. They can be used safely behind non-flammable materials such as plasterboard which makes a well-suited product for areas where flame resistance is necessary such as between houses / flat apartments.
