WARNING! This facing will burn. Do not leave exposed. It must be covered with gypsum board or other code-approved materials and installed in compliance with all building codes.
Can you put drywall over foil insulation?
Only if there is an air gap in the assembly; typically the air gap would be between the outer layer and the foil layer. If you are placing the drywall directly on top of the foil, then the other side of the foil must be open to an air gap, not insulation or some other material.
Can you insulate over radiant barrier?
Quote from the video:
Quote from Youtube video: It's going to help retain radiant heat but more importantly it's going to act as an air barrier to reduce the convective air looping.
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 aluminum foil a radiant barrier?
Aluminum foil has the radiant barrier properties of high reflectivity and low emissivity. That means the foil reflects much of the roof’s heat back upward. The low emissivity property of the foil reduces the amount of heat that the foil radiates on through to the attic insulation below.

Can you put drywall over radiant barrier?
Yes, you can install drywall over a radiant barrier, but only if there is a space of at least half an inch thick between the drywall and the radiant barrier.
Can you use insulation board instead of drywall?
Instead of using a more complicated or expensive alternative, such as decorative fiber cement boards, fiberglass panels or magnesium oxide (MgO) board, consider insulating your drywall with engineered EPS foam panels, such as InSoFast UX 2.0, particularly in a moisture-prone basement.
Can I use radiant barrier sheathing for walls?
Thermostat radiant barrier sheathing can also be used on gables and walls to reduce solar heat gain through these areas. This is especially true for southern exposure exterior surfaces that can absorb heat from prolonged exposure to the sun.
Do you need insulation if you have radiant barrier?
Radiant barriers reflect radiant heat.
Then, the heat transfer method switches from radiant heat to conductive heat to move through the attic insulation and into your home. This is why you need both types of insulation.
Which way should radiant barrier face?
According to research conducted by the Florida Solar Energy Center, the foil-side of your radiant barrier should be facing down. It should be towards the interior of the house and right under the roof sheathing so that homeowners can optimize its effectiveness when it comes to reflectivity and emissivity.
What is the R value of aluminum foil?
According to ASHRAE, when just a little condensation is visible on aluminum foil, the emissivity can reach 0.2 to 0.3, which would decrease that R-value down to R-3.86.
Does radiant barrier need air gap on both sides?
Typically we suggest you have an air gap between 1/2″ and 3/4″ for the radiant barrier to work. Air gaps larger than this work well too – they promote ventilation on the foil and help keep the air dry and the air temps lower. Insulation is technically a solid with a lot of air in it therefore, it is NOT an air gap.
How do you use aluminum foil for insulation?
Using Aluminum Foil
Completely cover all windows with aluminum foil and secure it with a heavy-duty tape such as duct tape. The shiny surface will reflect the sunlight’s rays. You can also insulate cold food when it will be near the sun.
How do you install radiant barrier in a wall?
Quote from the video:
Quote from Youtube video: And you really want to do it the way you do is you're going to put some foam strips in then you're going to staple your foil up so the foil is going to go. Basically.
Where do you put reflective foil insulation?
5 Places in Your Home where You Can Use Foil Insulation

- Walls. This type of insulation can successfully be used for walls as well. …
- Ceilings. …
- Floors. …
- Conversatory.
Does radiant barrier work in winter?
Radiant Barrier Insulation Benefits
Works to keep warm air in during the winter and solar radiant heat out during the summer. Prevents up to 97% of solar radiation. Improves energy efficiency and lowers utility costs, especially if HVAC and duct systems are located in the attic.
Is radiant barrier a fire hazard?
Metalized Film Radiant Barrier products offers less protection against a flame and easily will catch fire if exposed to any flame.
What is the R value of radiant barrier?
NO R-value
Radiant barrier on its own has NO R-value; R-value is attributed to materials slowing conductive heat. AtticFoil™ works to block radiant heat (97%) coming in to the attic by stapling it to the rafters, but it has no R-value.
How much does radiant barrier Reduce temperature in attic?
However, according to studies done by the U.S. Department Of Energy, it is generally accepted that installing radiant barrier in the attic will reduce heat gain through the ceiling by 40% typically leading up to a 17% reduction on heating and cooling utility bills.
How long does radiant barrier insulation last?
Standard insulation methods including radiant barriers last anywhere between 80 to 100 years, as long as they are installed correctly. You can use it for decades without significant problems.
Does radiant barrier affect WIFI?
With Wi-Fi signals, unless the radiant barrier is between you and the router, there is unlikely to be any impact.
