rFoil Reflective Insulation for
Home/Residential Use

rFoil is ideal for your home. Not only does it reflect up to 97% of radiant heat, it's also a vapor barrier and a radon barrier. Some applications for it are:

  • Use it in the walls to increase your insulating value
  • Use it instead of a vapor barrier in new home construction
  • Insulate a concrete foundation or basement AND use it as a radon barrier
  • Use it with a radiant floor heating system to reflect heat UP into your home where it belongs

In the walls/ceiling

The easiest time to install rFoil is during new home construction. It works best in conjunction with regular fiberglass insulation. After the fiberglass is installed in the wall and ceiling cavities, cover them with Bubble Barrier and staple it to the wall studs. Then put up your drywall as you normally would (or would hire someone to do it).

Note: Because rFoil is a vapor barrier, do NOT use another vapor barrier with it. You will get vapor lock inside the walls, which can ruin your insulation. It is also a good idea to use unfaced insulation (i.e. no brown kraft paper). However, if you are already using it, be sure to cut a few 6" cuts into the kraft paper with your utility knife before installing the rFoil.

In the attic

If your house is already in place, there is a way to get the same benefit by installing it in your attic. Since most of the heat is lost or gained through the attic, this is the most important area to insulate. Because Bubble Barrier is a vapor barrier, it is necessary to use another product called No-Tear (see the explanation below). This is a no-bubble insulation that is perforated. The perforations allow moisture to escape, but the heat is still blocked. To install it, just lay No-Tear on top of the existing fiberglass and staple it into place.

Why should I use No-Tear in my attic?

Since Bubble Barrier doubles as a vapor barrier, any moisture leaving your house will bounce off of it and soak up the fiberglass already in place. After that, the fiberglass will be ruined, and water spots will appear in the ceiling (and that's not good). This is why perforated No-Tear is the best option. This is also why Bubble Barrier should be installed closest to the inside of the house/next to the drywall -- drywall is NOT affected by the vapor barrier qualities of Bubble Barrier.


In the floor/crawlspace

Heat moves toward cold; cold doesn't move. As a result, heat will sometimes leave your house through the floor. If your floor is cold in the winter, it's not the cold coming in, it's the heat leaving. To prevent this, insulate your floor from underneath. Just go into the basement or crawlspace, and install Double Bubble Foil in the space between the floor joists, or run Double Bubble straight across all the floor joists. 97% of that heat loss will be reflected back into your home.

Application information is available from WE International.

On my water heater

The cost of operating a water heater can be up to 18% of your home heating bill. But wrapping a water heater with rFoil can save up to 15% of your water heating cost. Think of it this way, if your home heating bill is $150 per month, $27 of that probably went to heating your water. By wrapping rFoil around your water heater, you could save $4.05 per month, or $48.60 per year.

To see if you need a water heater blanket, feel the side of your water heater. If it's warm to the touch, that means heat is escaping through the walls of the heater. If it's cool to the touch, it's either broken, or already well insulated.

On heat ducts

It's possible to increase the efficiency of a home heating system just by wrapping the ductwork. Most ductwork is made of galvanized steel, which does nothing to stop heat loss. Wrapping rFoil around the ductwork will reduce heat loss through the steel, which will bring more heat to the farthest ends of your house, and cut down on your heating bill.

As a housewrap

Although a large portion of heat is gained and lost through the roof, a significant portion is lost through the walls. To prevent this extra loss and gain, use rFoil Ruff Rap as a housewrap, before installing vinyl siding or wood clapboards. Ruff Rap is perforated, so it will still allow moisture to leave your house as needed, but will reduce energy loss better than other, non-reflective housewraps on the market.

Ruff Rap is made with white poly on one side, and aluminum on the other, so you can even use Ruff Rap under brick.

Ruff Rap comes in 54" x 200' rolls (900 square feet), and it installs like regular house wrap.

In a mobile home

Some older mobile homes often require additional insulation to help cut heating and cooling costs. One of the most common parts that needs insulation is the floor. If you have cold floors in the winter, chances are, there's just not enough, if any, insulation underneath your home to keep it as warm as you want it. The best way to find out is to crawl underneath your home and see. If you don't see any insulation, there isn't any (it's not hidden underneath a subfloor).

As we've previously discussed, rFoil can be used to insulate mobile homes. Just by attaching it to the floor joists, you can keep your whole house warmer in the winter, cooler in the summer, and lowering your heating and cooling bills. See "In the floor/crawlspace."

Unfortunately, retrofitting the walls and ceiling of a mobile home is extremely difficult, very costly, and pretty messy (but don't let us stop you!). While it is possible to do it, you may end up spending more money than you would ever save over the life of the home. But we do have other products available which will also provide this type of insulation. Contact us at (574) 457-3066, or email us at weexport@we-intl.com, and ask for information on these products.

What else do I need?

When using rFoil reflective insulation, there will be seams and splices that need to be covered up, to help maintain the vapor barrier -- it's not needed with No-Tear radiant barrier.

We have 2" and 3" reflective tape available for covering up seams (personally, we recommend the 2" for regular foil insulation, and 3" for Concrete Barrier). We also recommend that you get one roll of tape for every roll of insulation.
