SADDLE METHOD
Foilboard Saddles make underfloor insulation installation straightforward and effective. Designed for timber and steel frames in new builds, they hold insulation panels securely between joists, ensuring proper positioning and stability. By maintaining a reflective air gap, Saddles optimize thermal performance, enhancing energy efficiency and indoor comfort. This simple accessory ensures a durable and precise underfloor insulation solution.
