Reflectix is now offering a dramatically improved performance application for the crawl space. This R-21 application includes a double layer of the Reflectix® Reflective/Bubble product. Its ease of handling and installation makes it the obvious choice when looking at crawl space insulation options. It comes in convenient roll sizes that install cleanly and quickly. The product is dust and fiber-free, and does not require any protective garments or respirators to work with.

Works great for putting in the windows between the glass and shade on a hot summer day

There is zero chance that is R21. The two layers create a moisture barrier between them. Where does the moisture go?

@toddhare8225 Месяц назад

If you have moisture in your crawl space you need to resolve this issue first. Moisture comes from the ground, Reflectix is a moisture/vapor barrier that will help to keep that moisture from your floor joist and home. All insulations use trapped air to create/increase R values. If you take a 3" thick piece of fiberglass insulation that is rated at an R13 and compress it down to 1" it is no longer an R13. Why? You didnt remove any product but you did remove the amount of trapped air by compressing the product. Reflectix doesnt have these fibers to trap air so you need to create a trapped air space. This application is, in fact, an R21 and has been tested at a third party testing facility to support this.

This method will ensure that if there is any moisture trapped between the joists it will stay there - rotting your floor joist and subfloor. I can't help but wonder who thought this would be a good idea.

Well, what would you suggest outside of fiberglass mat that would become soaked. Closed cell foam if installed similarly would trap moisture, as well as any moisture barrier. Ideas?

@@hillbilly4christ638 Seal the crawlspace and install a dehumidifier. That's what works in the south.

Is there any benefit to using this method on a garage door?

@toddhare8225 Месяц назад

There is. Reflectix radiates heat back at 96% so your garage will only feel the effects of 4% of the radiant heat coming of of your door when installed correctly.

Why do you need two layers?

@toddhare8225 Месяц назад

Two trapped air spaces are required to increase the R value to an R21. One trapped air space is R16.

@@toddhare8225 thank you. Interesting

@bruceclark7198 4 месяца назад

False advertising! This product may be useful for some applications, but it's resistance to heat flow is not R21.
