Heat-Ceil directly fixed to flooring with 4mm glue/reflective airspace provides an extra insulation layer from reflective air films.
Heat-Ceil combines the exceptional thermal qualities of EPS and reflective air films into one easy to use product that requires no special masks or clothing for installation.
Product Description: Heat-Ceil Insulation is a light weight rigid board made of an SL grade polystyrene core with pure aluminum foil laminated to both sides that reflects 97% of radiant heat, contains fire retardant and is water resistant.
Sheeting Sizes Floor Joist Centre's mm x 1200mm Cut and packed to ship
Heat-Ceil alternatively placed with 100mm airspace improves thermal values or saves money from thinner insulation.

Changes to the building systems described above will alter the total thermal resistance value.
Ceilite provide a Thermal Insulation Evaluation from certified engineer for any specified building system.
The Building Code of Australia also list the thermal properties of both polystyrene and reflective airspaces.
