Reflective Bubble Foil Insulation & Radiant Barriers
High-Performance Thermal Protection for Every Project
Welcome to Wellco Wholesale's premier selection of Bubble Foil Insulation, also widely known as reflective foil insulation or radiant barriers. Unlike traditional fiberglass insulation that slows down heat transfer by absorbing it, our aluminum foil insulation works by reflecting up to 96% of radiant heat away from your structure. Composed of layers of polyethylene air bubbles sandwiched between highly reflective pure aluminum foil, this material provides an exceptional thermal break, effectively keeping spaces cooler in the summer and warmer in the winter.
Whether you are looking for double bubble insulation rolls for maximum durability or specific sizes for smaller jobs, our inventory is designed to meet rigorous professional standards.
Versatile Applications: From Attics to Metal Buildings
Our reflective insulation is lightweight, fiber-free, and non-toxic, making it easy to install without protective gear. It is the ideal solution for a wide variety of residential, agricultural, and commercial applications. Common use cases include:
- Attics & Crawl Spaces: Staple to roof rafters or crawl spaces to dramatically reduce energy bills.
- Metal Buildings & Pole Barns: Prevent condensation and control temperature in steel structures, warehouses, and agricultural sheds.
- HVAC Duct Wrap: Wrap ductwork to maintain air temperature and improve system efficiency.
- Garage Doors: A simple DIY upgrade to insulate standard garage doors against extreme weather.
- Concrete Slabs: Use as an under-slab vapor barrier to prevent moisture migration and heat loss in radiant floor heating systems.
