Foam Insulation for an Attic or Basement

Insulation is one of the home improvement solutions that help homeowners make dramatic savings on energy bills. It also makes the house more comfortable to live in. The attic and the basement are two areas in the home that can benefit from good insulation.

Foam insulation on basement walls and attic roofs keep the house warm in winter and cool during the summer while keeping out moisture. There are different kinds of foam insulation and you must find one that provides the amount of insulation and moisture control that you need.

Foam insulation is sprayed onto walls or into hard-to-reach places. It can be retrofitted, making it ideal for insulating existing structures and attics and basements where there may be unfinished walls or ceilings. There are two types of foam insulation: rigid foam and spray foam. They have different uses and a combination of the materials can insulate your home more effectively.

Kinds of Insulation

1. Open-Cell Foam: The tiny cells of the foam are not completely closed but are broken. Air fills the open space inside the materials, making the foam weaker or softer. Open-cell foam is porous and allows moisture day rut nhua to penetrate. It has a lower insulating property.
2. Closed-Cell Foam: The foam cells are closed and packed tightly together. The cells are filled with the gas that helps the foam rise and expand. Closed-cell foam is an excellent insulator. It is very strong and provides some degree of structural support.

Types of Insulation Materials

• Cementitious: This is cement-based foam used as sprayed-foam or foamed-in-place insulation.
• Phenolic: Phenolic or phenol-formaldehyde foam was popular in the past as rigid foam board insulation. It has a relatively high insulating property. Its major disadvantage is that it can shrink up to 2 percent after curing. It is no longer as popular as before and is only available these days as foamed-in-place insulation.
• Polyisocyanurate: This foam insulation for attics and basements is available as liquid sprayed foam and rigid foam board. Foamed-in-place applications are cheaper to install than foam boards and perform better because the liquid foam molds itself to all surfaces.
• Polyurethane: This is a closed-cell foam insulation and one of the best insulating materials that you can find. Polyurethane insulation is available as rigid foam board and liquid sprayed foam.

There are many different kinds of foam insulation for an attic or basement. A professional will be able to advice you on the best kind of material to use for your home improvement project. You will have to consider the age of your home, geographical location, and your budget. Extreme climates in the region where you live will demand a higher level of insulation and you may have to deal with moisture control as well.
