Ideal for Retrofit Wall Insulation
Icynene classic pour fill is particularly successful at insulating cavities that are partially filled with rigid board PIR or polystyrene board and is effective on three fronts:
- the classic pour fill will push the rigid board firmly against the inner leaf making it more effective,
- it will fill any voids that are present in the board insulation and
- it will fill the remaining cavity void to give a complete fill of insulation and an excellent level of air tightness.
