Foundation Wrap Insulation

Product Overview
Reflective Insulation for Foundation Systems
Insulapack reflective foundation wrap is designed to improve thermal performance and protect building foundations from heat loss and moisture exposure.
The flexible multi-layer insulation structure supports installation around foundation walls and structural building elements.
Here are some of the properties of Insulapack's foundation insulation products:
Concrete Foundation Insulation, also known as Foundation Wrap
High-density foil-bubble wrap with increased Poly thickness to 6mm increases strength to resist compression
½ inch thickness ≈ R5.4 (layered to your desired R-value)
Made of plastic (poly) that does not absorb water
It consists of continuous channels to allow moisture and water to flow downwards into the ground or weeping tiles, leaving a dry foundation surface.
Provides insulation to the concrete surface
Provides continuous and seamless covering up to 750 feet long
Width of roll up to 48 inches
Very lightweight – a roll can be handled very easily by one person

Thermal Protection for Foundation Systems
Insulapack reflective insulation helps reduce radiant heat transfer through foundation structures while supporting moisture protection and building durability.
The thin insulation profile allows installation around foundation walls and structural systems where space may be limited.
Here are some of the applications of Insulapack's Foundation Wrap:
Install Insulapack foil-bubble foundation wrap insulation the same as any other foundation wrap
Use an adhesive or insert concrete fasteners through the foil-bubble wrap
The adhesive should not fill gaps between the bubbles (drainage path)
Bubbles go directly against the wall; foil goes to the outside
Extra thick 6mm poly bubble skin prevents bubbles from popping due to pressure
Proper drainage around footing needs to be in place to accept water as it drains
Sealing the top will prevent soil from getting in but does not have to be watertight

Why Insulapack
Why Use This Product
Foundation insulation in commercial buildings faces a specific challenge: moisture. Reflective bubble foil foundation wrap addresses this directly. The aluminum facing is moisture-resistant, the sealed bubble construction creates thermal resistance without absorbing water, and the direct-contact installation means no gap for moisture to accumulate. R-10.6 per inch, ASTM E84 Class A. Suitable for new construction and retrofit applications across Canada and the United States.
