Easy Do It Yourself Foam Insulation Kits

By Edited Feb 17, 2014 0 0

There are many types of do it yourself foam insulation kits, as well as purchasing everything separately in order to apply it on your own.

Types include; liquid foams, molded expanded polystyrene foam board, extruded expanded polystyrene foam board, polyurethane, and polyisocyanurate.

Each one is slightly different than the next and choosing which one will depend on what you want to insulate.

Liquid foams - This can be applied in small or large quantities, it comes in a variety of can sizes. The small containers are usually a liquid, while the larger ones is a pressure sprayed substance. They both expand and harden the same, as well as taking the shape of whatever it is filling.

There is a slow curing type, which allows it to flow over an obstruction before hardening. Liquid foams are generally urethane foams, although there are latex and organic based ones available as well. The latter two types of foam insulation don't have as high of an R-value as the urethane-based foams. Molded Expanded Polystyrene

Foam Board - Also known as MEPS, this closed-cell product can be molded into various shapes. It can also come in sheets for insulating houses. The common name for this type of insulation is "beadboard" and its R-value is 4 per inch of thickness.

Spray Foam Insulation
MEPS foams are also available as little beads of foam. This kind can be poured into hollow wall cavities or inside concrete blocks.

Extruded Expanded Polystyrene Foam Board - This form of do it yourself foam insulation is similar to MEPS. Shapes are formed the same way as in MEPS, but it is more expensive and its R-value is around 5. Polyurethane and

Polyisocyanurate - These are both closed-cell foams with low-conductivity gas enclosed in the cells. The R-value is around 7 or 8 per inch. Both of these are found as a liquid spray, rigid boards, or poured foam. The foamed-in-place applications of either of these usually costs less than installing foam boards. These also tend to have better performance since they conform to the surface they are put on.

Foam insulation kits are sold with or without safety kits and cleaning equipment. Some tanks are disposable, while others are basically for rent and need to be returned after the job. It is a messy job, so be prepared and have the proper clothing before taking on a do it yourself foam insulation kit.
