It’s a thin, reflective insulation made from multiple layers of foil, wadding, and membranes designed to reflect radiant heat and improve thermal performance with minimal thickness.

Yes—especially in loft conversions, rafters, and tight spaces. However, it can also be paired with mineral wool or PIR for even better performance.

Foil reflects radiant heat back into the home in winter and reduces heat gain in summer. Its multiple layers slow down heat transfer and improve airtightness.

Yes. For maximum performance, foil insulation should be installed with at least one air gap. This allows the reflective layers to work effectively.

Yes. It’s non-toxic, lightweight, and easy to handle. It also helps improve airtightness, reducing draughts.

Yes. When installed with proper ventilation and air gaps, foil insulation can help reduce condensation by improving airflow and regulating temperature differences.
