Eco-Cavity - Partial Fill Cavity Wall Insulation

Eco-Cavity insulation boards are suitable for partial fill cavity wall insulation. They achieve high levels of thermal performance for thinner constructions whilst maintaining a clear residual air gap; effective protection against driving rain, particularly in coastal and exposed locations.


Suitable for use in new build walls, Eco-Cavity provides a cost effective means of reducing CO2 emissions and compliance with Building Regulations/Standards.


EcoTherm Eco-Cavity comprises a fibre free rigid polyisocyanurate (PIR) insulation core faced with aluminium foil composite on both sides.  The boards are conveniently sized to co-ordinate with brick and block dimensions and allow the insertion of wall ties at the appropriate spacing.
