Does foil insulation really work?
One often-overlooked type of insulation is liquid foil insulation. While liquid foil forms a thin layer, it actually works very well as insulation, as well as a moisture barrier. Foil is also known as radiant barrier insulation. If you are wondering how foil insulation works, it works differently from other types of insulation. Most insulation prevents the conduction of heat, preventing heat from moving. Foil, instead, reflects heat and works just as well as other types of insulation, so it prevents radiant heat loss. It’s especially effective if you have limited space, like an apartment or loft, in which to insulate. Some types are also easily applied, as it is sprayed on as a liquid. In larger spaces, it may not be as effective. Another distinct advantage foil has over other types of insulation is that it typically lasts longer and won’t degrade over time.

When to use foil insulation
Foil insulation tends to work best in areas where space might be too restricted to use other types of insulation. This type of insulation is also best used in hotter climates, where it will best reduce the radiant heat coming off the underside of your roof. It will also retain heat better when the weather cools off.
What is the purpose of foil faced insulation?
Installing foil-faced insulation is good if you want to reduce radiant heat in your attic. Unlike other insulation, it doesn’t absorb heat. Instead, it has stronger reflective properties to reduce heat. It’s also useful for noise reduction. Typically, foil insulation is installed with the foil side facing the warm air surface. The foil reflects the heat toward the interior of the building. It will reduce heat radiation in the summer and retain it in the winter.
Can foil faced insulation be left exposed?
When installing foil-faced insulation, it cannot be left exposed. This is because the foils used in it are often combustible. Leaving the insulation exposed can create a fire hazard. When the installation is installed, it should be in contact with an approved ceiling, wall, or flooring material. There is only one type of flame retardant foil insulation—FSK-25—that can be left exposed.
Is foil insulation flammable
Although foil insulation can be valuable in hot climates if it is not installed correctly and left exposed, a fire hazard is created. Not all foil materials, however, are flammable. FSK-25 materials are flame retardant. Many other types of insulation are not combustible but can smoke and release toxic chemicals. One of the chief risks with the combustible materials is the heat increase when there is a fire. This heat increase accelerates fires. Also, the more insulation there is in a room, the higher temperature a fire will be. Insulation wrapped around wiring or other heat-producing devices puts those materials at greater risk of overheating.
Is foil insulation waterproof
One of the advantages of foil insulation has over other types of insulation is that it is largely waterproof. It also serves as a vapor barrier. If there is a roof leak or plumbing leak, the foil is less likely to degrade or develop mold and mildew.
Can you paint over foil insulation?
If you want to paint over foil insulation, you can, although because it is non-porous, it’s less adhesive so you will have to follow some steps to make sure the paint stays on. Before you attempt to paint in an area that might be poorly ventilated, you’ll want to wear a respirator.
- First dust the foil face using sticky tack cloths.
- Make sure to protect the area around the insulation with painters tape and drop cloths.
- Use a roller to coat the foil with a water-based metal self-etching primer.
- Smooth the primer with a polyester paintbrush to ensure there are no flaws.
- Let the primer dry for about four hours.
- After you wash the brush and roller, coat the foil with satin or semi-gloss latex paint with the roller.
- Smooth the paint with the brush.
- Wait two hours to let the paint dry.
