Under-Floor Insulation System:
Fixed between Joists with Reflective Still Airspace
Heat-Ceil placed with a reflective airspace below flooring improves thermal values by providing an extra insulation layer from reflective still air films or saves money
with a thinner sheet of insulation while maintaining required Total R.
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 to fit between joists.
Sheeting up to 5000mm x 1200mm for placing bottom of floor joists.
Example: Total R 2.0 summer climate achieved from Building Insulation System described:
| Aluminium Foil reflects 97% of radiant heat. |

* Determinations Based upon AS/NZS 4859.1:2002/Amdt 1 2006, Materials for Thermal insulation of buildings.
Larger Reflective Airspaces or Direct fix method may also be used.
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.
We invite you to contact us about having your individual building system tested
or to arrange a completely independent 6 star energy efficiency report. |
