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 a strong, rigid board
suitable for self-supporting applications
in floors, walls and roofs. It can
withstand the loadings in
groundbearing floors.
Environmental
Ballytherm Insulation is produced with a
zero ozone depletion blowing agent.
The Insulation boards' low thermal
conductivity mean less material is
required to achieve a given thermal
resistance than for most other insulants.
Ballytherm Insulation has a GWP
