250 Sq. Ft. Aluminum Foil Vapor Barrier Insulation Roll – 4ft X 62.5ft, 8 Mil Solid, Waterproof & Tear-Resistant For Sauna & Radiant Heat

About This Product

If you're building or upgrading a sauna, this aluminum foil vapor barrier is exactly what you need to keep moisture out and heat in.
This roll covers 250 square feet – that's 4 feet wide by 62.

5 feet long – and it's a solid, non-perforated 8-mil sheet.

No pinholes, no perforations, just a solid layer of protection.
It's double-sided with 99.

9% pure aluminum that reflects up to 97% of radiant heat, so it helps keep your sauna hot in winter and cooler in summer.

The woven polyethylene scrim gives it industrial-strength tear resistance – you literally can't rip this stuff by hand.

Plus, it's passed the ASTM fire test (E84 with E2599 mounting), so it meets building material safety standards.
Great for saunas, steam rooms, or anywhere you need a waterproof, heat-reflective barrier that's tough as nails.
