Is Mylar bubble wrap a good insulator?
Is Mylar bubble wrap a good insulator?
Foil-faced bubble wrap is a radiant barrier. It’s not insulation. A radiant barrier reduces heat transfer by radiation and has two excellent applications in homes.
Does foil faced insulation work?
RadiantGUARD® foil faced insulation is completely different. This barrier actually reflects radiant energy that can translate into heat, thereby reducing gain in the summer and loss in the winter. In fact, foil bubble insulation can reflect upwards of 95-97% of the radiant heat that strikes it making it very effective.
Is mylar a radiant barrier?
It’s a radiant barrier.
What is Mylar bubble wrap used for?
2 layers of metalized mylar foil with a 3/16″ bubble in between. This can be used in a variety of applications including building and window insulation, heating and cooling ducts, radiant floor heating, plumbing applications, insulating your garage door or simply as a sun/heat block for your car windshield.
What is the R value of reflective foil insulation?
Most brands of foil-faced bubble wrap are only 3/8 inch thick or less, and have an R-value of only 1.0 or 1.1. Since the product often costs more per square foot than 1-inch thick rigid foam rated at R-5, why would anyone use bubble wrap as insulation?
What is the best foil insulation?
Multifoil Insulation is More Sustainable Than Other Options Multifoil insulation has even more efficient benefits than other insulation options on the market. SuperFOIL insulation is also better for the environment because it’s made with 40% recycled materials and fully recyclable at the end of its life!
Do you need Vapour barrier with foil backed insulation?

What is Mylar film made of?
Mylar, also known as BoPET (Biaxially-oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation.
What is the temperature range for Mylar film?
Mylar® polyester film retains good physical proper- ties over a wide temperature range (–70 to 150°C [–94 to 302°F]), and it is also used at temperatures from –250 to 200°C (–418 to 392°F) when the physical requirements are not as demanding.
Can you put Mylar over attic floor insulation?
