Product Overview
Reflective Insulation for Roof & Ceiling Systems
Insulapack reflective insulation is designed to reduce radiant heat transfer from roof structures and attic spaces into interior environments.
The multi-layer bubble structure combined with reflective aluminum foil surfaces improves thermal efficiency while maintaining a thin insulation profile suitable for modern construction systems.




Thermal Performance for Roof Assemblies
Insulapack reflective insulation helps control radiant heat entering buildings through roof systems. This reduces cooling loads in warm climates and improves energy efficiency year-round.
When it comes to insulating your cathedral ceilings, we offer two effective options to meet your needs. Our vented cathedral ceiling insulation is designed to create a well-ventilated space, allowing air to circulate and preventing moisture buildup. This ensures a comfortable living environment and helps maintain energy efficiency throughout the year. On the other hand, for a more airtight solution, our unvented cathedral ceiling insulation is the perfect choice. By sealing the area, it prevents air leakage and minimizes heat loss, offering enhanced thermal performance and reducing energy consumption. Whether you prefer a ventilated or unvented approach, our cathedral ceiling insulation solutions provide reliable and effective results, ensuring your home remains cozy, energy-efficient, and well-protected against the elements.
Here are some of the properties of Insulapack’s Roof & Ceiling Insulation:
Industrial, commercial and residential roof and ceiling insulation
High-density bubble wrap with increased poly thickness to resist compression
1/2 inch thickness ≈ R5.4 (layered to your desired R-value)
Made of plastic (poly) that does not absorb water
Poly layers act as a built-in vapour barrier
Conventional vapour barriers can also optionally be used
Very lightweight – a roll can be handled very easily by one person
Very clean, no rot, no mold, no pests, no masks or gloves required
Here are some of the applications of Insulapack’s Roof & Ceiling Insulation:
Watertight poly acts as built-in vapour barrier
Traditional Vapour Retarder is optional

Why Insulapack
Why Use This Product
Radiant heat gain through commercial roofs is one of the largest contributors to HVAC load in Canadian and US buildings. Insulapack reflective roof and ceiling insulation reflects up to 95% of radiant heat before it enters the building envelope — reducing cooling load and improving system efficiency. No airspace required between the insulation and the roof deck. R-10.6 per inch, ASTM E84 Class A fire rated, LEED compliant. Suitable for new construction and retrofit roof assemblies for commercial contractors across Canada and the United States.
Application Areas
Where Roof Insulation Is Used
Insulapack reflective insulation is designed for roof and ceiling assemblies where radiant heat control and energy efficiency are required.
