StyroLink is a highly compressive purlin insulation material that assists with thermal efficiency on commercial metal deck roofing applications.


Manufactured from Styroboard XPS extruded polystyrene, StyroLink roof spacers have been designed specifically to allow for the installation of thicker insulation without compromising on thermal performance. The use of StyroLink on top of each purlin can provide a break for the insulation blanket to recover to its nominal thickness while still retaining high R-Values.

The closed cell structure of the rigid extruded polystyrene panels means that StyroLink delivers a high compressive strength as well as maintaining thermal performance.

Unlike many roof spacers in the market, StyroLink is 100% Australian made. Manufactured at our Victorian state-of-the-art facility, our roof spacers are made from the highest quality extruded polystyrene, wiht a kPa rating that exceeds BCA regulations. Don't risk non-compliance or a failing roof system by using imported roof spacers of inferior compressive strength.

StyroLink roof spacers are can be custom cut to your specific requirements. Light weight and easy to install, all StyroLink roof spacers are packed in easy to handle bags to protect the product in all weather conditions.
