How to Use DIY Foam Insulation Kits

DIY Foam insulation kits are an quick and easy way of reducing the amount of heat loss from your attic or roof space. Foam insulation can be used in almost any area, but it is particularly useful in areas such as attics where small holes can cause a great deal of hot air loss. Using spray-in foam insulation kits is much easier than attempting to fit foam insulation from a roll into tight spaces.

Varieties of Foam Insulation

There are a range of DIY foam insulation kits including open cell and closed cell foams. Open cell is more likely to allow air to fill spaces in between the foam, while closed cell foam sets in a more rigid form, and is less liable to penetration from water and air. Closed cell foam is significantly more expensive than open foam, so if you are planning to cover a lot of space, you will probably be better off purchasing the latter. If you know that you are more vulnerable to cold and damp in the attic, you can invest in closed cell foam. Experts in insulating foam insulation sprays recommend using the closed cell, due to its effectiveness in regulating hot and cold air in open spaces. Examples of closed cell foam includes soythane, which is a renewable spray which causes moisture to bead and fall away, rather than other forms of closed cell insulation, which absorbs moisture and leaches it away through openings.

Safety and Protection

DIY foam insulation kits contain toxic chemicals during the installation process, so extra care should be taken when using the spray. You should protect yourself by using a breathing or gas mask, safety gloves, and clothes with long legs and sleeves. You should also remove any fiberglass insulation which is in the attic spaces. If your home was built before 1990, and you don't think that the insulation has been moved since then, stop all projects, and get professional assistance in removal. Check the area you intend to insulate for mold or rot, and don't attempt to use the foam if you see mold, but rather get it treated before proceeding.

Using the Spray

Once you have cleared your space, and are properly protected, using the DIY spray foam is relatively easy. The spray combines 2 chemicals, which need to be applied evenly in order to ensure proper insulation throughout the roof. While insulating the roof, make sure that you tread carefully on the stud boards, as stepping onto the boards between these studs can cause you to break through the ceiling of the room below.

When spraying the foam, don't spray too much in one area. You may receive advice about how thick your insulation should be. make sure that you are familiar with these regulations before you attempt to use DIY foam insulation spray. Local regulations should not require you to spray more than 1 inch thickness throughout. The foam should be left for around 1/2 an hour, and then either sprayed again, or covered with protective sheeting and left to keep your home warm.
