Insulated I-Block for Rim Board

Efficient Thermal and Air Seal Solution

The SnapTight Insulated I-Block for Rim Board is expertly engineered to seal and insulate the often-overlooked gap between floor joists and rim boards. Made from EPS, this custom-fit block effectively reduces thermal bridging and air infiltration—common sources of energy loss and moisture issues in building envelopes.

Designed for both new construction and retrofit projects, the I-Block improves overall energy efficiency while enhancing occupant comfort through noise reduction and improved indoor air quality.

Key Features:

• R-value of 26 for superior thermal resistance

• Lightweight and easy to install with standard framing systems

• EPS provides durable, long-lasting insulation

• Reduces air infiltration and thermal loss at critical floor perimeter connections

• Specifically designed to fit between floor joists and rim boards for a tight seal

• Improves energy efficiency, lowering heating and cooling costs

• Resists moisture and mold, protecting the building envelope

• Quick installation saves time and labor costs

• Helps reduce noise transmission between floors
