Spray Foam Insulation – An Overview

July 18th, 2012

Spray foam insulation (SFI) is a type of insulation used in walls, ceilings and other areas of a building. It helps keep the air inside warmer when it is cold outside and vice versa. Earlier, this insulation could only be handled by professionals. Nowadays, do-it-yourself kits are easily available in the market. How does spray foam insulation work? Spray foam insulation is made of resin and other chemicals like polyurethane. When it is sprayed, the resin and the chemicals combine to create foam, which expands and solidifies. This dries quickly providing permanent insulation. If the foam goes outside the desired area, you can cut off the excess insulation. Benefits of spray foam insulation
  1. Reduces energy costs – Studies prove that about 40% of energy in your home is lost due to infiltration of air. The air infiltrates in homes through windows, wall sockets and doorways. Spray foam insulation prevents air and moisture infiltration thereby reducing your energy costs by almost 50%.
  1. Live in comfort – SFI helps you to live comfortably in your own homes. It helps in keeping the interiors of your home warm during winters and cool during summers.
  1. Prevents entry of dust and pollen – Do you suffer from dust allergy? If yes, do not hesitate to seal your home with SFI. SFI makes it difficult for dust and pollen to enter your home.
  1. Reduces moisture and mold growth – Mold growth occurs where there is moisture accumulation. SFI prevents moisture infiltration, thereby drastically reducing mold growth.
  1. Improves the strength of the building – With spray foam insulation, your home will never sag over time. As this insulation is seamless and monolithic, it improves the stability of the building.
  1. Reduces sound travel – Loud noises will not be able to penetrate spray foam. So, you can enjoy a peaceful environment as the outdoor noise will never disturb you. Similarly, if you like playing loud music, you do not have to worry about disturbing your neighbors as the noise will not reach them.
  There are certain precautions to consider when insulating your home with spray foam. This spray can be dangerous during the application stage. The chemical particles can get into your eyes, nose and mouth if proper safety equipment is not worn. The eyes and respiratory system may feel irritation, which can lead to inflammations and other allergies. When applying foam insulation, you must wear long sleeves, goggles, gloves and breathing masks for protection.   Spray foam insulation also has certain disadvantages. It is expensive when compared to other forms of insulation such as fiberglass. The application part procedure can become messy. One has to be extra cautious and wear the recommended protective gear during spraying. It can easily spread over to areas you don’t intend to insulate. Moreover, if too much insulation is sprayed onto thin walls, the wall might buckle as the foam expands.   It would be wise to hire a spray foam insulation company to do the job for you. This saves you from all the mess, the hassles as well as any unwanted incidents.
