StyroLink®: XPS Roof Spacers 

High-Strength XPS Purlin Roof Spacer for Metal Roofing.
StyroLink Logo

Precision-engineered from Styroboard® XPS, StyroLink® roof spacers are a high-compression, thermally efficient solution for commercial metal deck roofs. Installed directly over roof purlins, StyroLink® creates a consistent gap for insulation recovery, allowing thermal blankets to retain their full nominal thickness and perform at peak R-Values. The closed-cell XPS structure ensures excellent water resistance, minimal thermal bridging, and long-term compressive strength. Lightweight and easy to handle, StyroLink® is custom-cut to your project’s needs and proudly made in Australia from recyclable materials.

StyroLink® is manufactured from Styroboard® XPS, which contains up to 90% recycled polystyrene. This recycled content is sourced through Foamex’s closed-loop recycling model, collecting clean waste from building site offcuts, factory floor surplus, and post-consumer packaging via dedicated drop-off points. By turning recovered polystyrene into high-performance insulation products, StyroLink® supports circular construction practices without compromising technical integrity.

FAQ's

Frequently Asked Questions About XPS Purlin Spacers

What is the purpose of a roof spacer?
A roof spacer is installed on top of each roof purlin to allow insulation blankets to spring back to their full thickness under metal roofing, preventing compression and loss of thermal performance.
StyroLink® is lighter, easier to handle, and reduces thermal bridging more effectively than metal alternatives. Its XPS core provides better insulation and water resistance, improving long-term performance.
Yes. StyroLink® is manufactured to exceed the compressive strength requirements set by the National Construction Code (NCC) and supports compliance with thermal bridging provisions in commercial roofing.
By allowing insulation blankets to fully recover, StyroLink® prevents thermal bridging and air leakage—two major causes of energy loss in metal roofs—resulting in more stable internal temperatures.
Yes. Made from recyclable Styroboard® XPS and produced in a closed-loop system, StyroLink® helps reduce waste and supports sustainable construction goals.
