Eco-Cavity Full Fill comprises a fibre free rigid polyisocyanurate (PIR) insulation core with aluminium foil composite facing on both sides. The tongue and groove edges ensure a continuous layer of insulation which increases protection from wind driven rain and also aids installation. Eco-Cavity Full Fill boards are conveniently sized to co-ordinate with standard brick and block dimensions allowing easy insertion of wall ties into the construction at the appropriate spacing.

Applications
Eco-Cavity Full Fill is suitable for full fill cavity wall applications, whilst maintaining a residual 10mm cavity. Eco-Cavity Full Fill is high performance insulation, and provides a cost effective means of reducing CO2 emissions and achieving compliance with Building Regulations / Standards. Maintaining a residual 10mm cavity helps resist moisture transfer, aids installation and accommodate mortar squeeze.

COMPRESSIVE STRENGTH
Typical compressive strength for the insulation exceeds 140kPa when tested to BS EN 826: 1996 Thermal Insulating Products for Building Applications-Determination of Compressive Behaviour.

DURABILITY
The product is stable, rot proof and durable and will remain effective as an insulation system for the life of the building. Durability depends on the method of application, the supporting structure and conditions of use. The fibre free insulation core and facings resist attack from mould and microbial growth and do not provide any food value for vermin.

WATER VAPOUR RESISTANCE
The board has a water vapour resistance of > 100MNs/g and will therefore, provide significant resistance to water vapour transmission.

RESISTANCE TO SOLVENTS
PIR insulation resists attack from alkalis, dilute acids, mineral oil and petrol. The fibre free insulation core is not resistant to ketonic solvents. Damaged boards should not be used.
