Can I use reflective insulation with fiberglass insulation?

If you want to combine insulation types, using reflective insulation and fiberglass insulation in a wall space can boost the R-value by 3.9 points. By utilizing reflective insulation, an R-21 total wall assembly can be created, with a vapor and moisture barrier.

Can you put Reflectix over insulation?

Reflectix can be used as basement ceiling insulation when precisely stapled to the centers of the floor joists above. The product must be applied tightly, with room for airflow. One benefit of using Reflectix over fiberglass insulation is that Reflectix resists mold and mildew well.

Is reflective insulation good for attic?

Not only will building or retrofitting your attic with reflective insulation and high-performance seaming tape help improve energy efficiency, but it also increases HERS ratings, life expectancy of HVAC systems, and saleability.

Where should reflective insulation be used?

Reflective insulation, installed in the attic ceiling, helps reflect sunlight and reduce the radiant heat transfer from the underside of the roof to the other surfaces in the attic. This helps keep your home cooler and more comfortable.

Is reflective insulation better than fiberglass?

The U.S. Department of Energy reports that reflective insulation is the most effective at preventing downward heat flow, making it a better choice for roof insulation where keeping heat out is the most important factor.

Is reflective insulation good for winter?

Radiant Barriers (Reflective Insulation)

Reflective, radiant-barrier insulation is usually made of aluminum foil with a variety of different backings, including plastic film and cardboard. This type of insulation is most effective in warmer climates, but can also be used for comfort and energy savings in cold weather.

How do you use a Reflectix in the attic?

Quote from the video:
Quote from Youtube video: No taping is required staple. The product to the rafters at three to four inch intervals ensure at least a one inch to two inch gap. All vents. Leave a gap on each side of the roof peak.

Can you put foil over insulation?

Is attic radiant barrier worth it?

Radiant barriers are more effective in hot climates than in cool climates, especially when cooling air ducts are located in the attic. Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate.

Is multi foil insulation any good?

Multifoil insulation is often carried out on new builds, but it can also be added to older properties. More energy efficient than many traditional types of insulation, it’s easy to install and has a number of useful properties, such as: Vapour control – this stops the insulation from becoming damp, keeping it effective.

How do you install attic reflective insulation?

Quote from the video:
Quote from Youtube video: The open Ridge method or the staple up method of installing radiant barrier foil. They're going to install the radiant barrier foil. And then come back with additional attic insulation.

What is the R-value of reflective insulation?

In short, reflective insulation can have an R value anywhere from R-3 all the way up to R-17.

What is foil insulation used for?

Foil insulation is ideal for hot weather, and is mostly used in roofs and walls. It’s designed to reflect heat radiation, but also comes combined with bulk insulation like glass wool or rock wool batts to create a composite type insulation, which insulates against heat transfer through convection and conduction too.

Does Reflectix keep heat out?

Reflectix is equally valuable for keeping cool on hot sunny days. The greatest source of heat when the sun is shining is the windows. The heat load can be so high that your air conditioner may be unable to cool your camper down to a pleasant temperature when the sun is beating on it.

Can Reflectix start a fire?

Reflectix® has a Class A/Class 1 Fire Rating on the Reflective/Woven Fabric/Reflective Radiant Barrier meeting all fire and smoke safety requirements of federal, state and local building codes. (Satisfies UL 723, NFPA 255 and UBC 42-1.)

What is the purpose of Reflectix?

Reflectix is polyethylene bubble wrap encased in reflective aluminum foil. The bubble wrap provides air space insulation and strength to support the reflective foil surface. For these applications, look for the double reflective version online or in your local hardware store.
