Insultrak® is a roof insulation spacer system designed specifically for use with faced flexible fibre and reflective foil roof insulation materials in over-purlin roof applications.
Insultrak® is a proprietary extruded polymer composite manufactured from 95% industrial mineral waste and recycled polymers, making it an eco-friendly “green” product. Insultrak® is manufactured in a standard dimension of 40mm x 40mm square for use with all thicknesses of faced flexible fibre and reflective foil roof insulation materials.
By being used as a spacer/packer between the insulation and the roof sheet, Insultrak® provides the necessary spacing to allow the faced fibre insulation to attain maximum installed thickness and significantly reduces backward pressure on the roof sheet or clip system. The use of Insultrak® in this application has shown to increase the thermal value of the insulation by up to 77% as opposed to the insulation being installed without any spacer/packer.
In the case of reflective foil laminate roof insulation materials their quoted Thermal Resistance (R-Values) according to SANS 1381-4:2013 are tested with a 40mm air gap on the “hot” side. The use of Insultrak® for these applications is therefore also perfectly suited and thereby ensures that the actual quoted thermal values are achieved.
Insultrak® is a solid spacer/packer with extremely high dimensional stability and strength, and will therefore not deteriorate, collapse or crack as has been found with foam spacers/packers. Insultrak® is non-combustible and therefore provides no additional fire load to a building. Proprietary spacer/packer systems such as Insultrak® are included in the new SANS 10400-XA Energy Regulations.
Fire Performance
Insultrak® has been fire tested according to the SANS 10177-10 application test for over-purlin roof insulation systems with an A1 fire rated faced fibre roof insulation and achieved an A1 Non-combustible fire rating.
