Made in CANADA 

Insulthane® Extreme is a 2 lb medium-density, HFO-blown closed-cell spray foam insulation designed to deliver high thermal performance and superior insulation values. It was the first spray foam system developed using an HFO blowing agent, achieving an ultra-low Global Warming Potential (GWP) of 1.

Key Features

• Sustainable Material Use
  This product incorporates recycled plastic into its raw materials, helping divert waste from landfills. On average, insulation for a typical home can repurpose up to 6,000 plastic bottles.
• Energy Efficiency
  Its strong thermal resistance and air-sealing capabilities can reduce heating and cooling costs by up to 40%.
• Radon Protection
  Recognized as a below-grade gas retarder (ULC ER-R40584), it functions as an effective barrier against radon gas, helping protect indoor air quality.
• Moisture and Mold Control
  By forming a continuous air seal, it limits moisture intrusion, stabilizes indoor temperatures, and reduces the risk of condensation, mold, and mildew growth.
• Structural Enhancement
  When applied within wall cavities, it can improve wall strength and durability. Testing by NAHB has shown racking strength increases of up to 300% compared to non-insulated wall assemblies.
