Being able to apply spray foam insulation yourself is a great way to save a significant amount of money. By finding the right home kit for the job, you will find it easy to make your home more energy efficient.

Step 1 – Determine Dimensions

To enable you to get an idea of the type of kit you need, you must keep in mind the area in which you intend to fit the spray foam insulation and the purpose to which it will be put. In addition, you must also make yourself familiar with the dimensions of the area, which will help you to understand the volume of insulation required. If necessary, make a note of this before you make a purchase.     

Step 2 – Types of Insulation

Understanding what use the spray foam insulation will be put to is necessary to help you decide what type you require for the job to be done efficiently. There are 2 main types of insulation foam: low density (which is also known as open cell) and high density (which is also known as closed cell). Low density foam grows to 10 times its original volume and forms a soft end substance in which the bubbles which form break open and allow air and moisture to pass through. High density foam does not increase in volume as much as its counterpart and sets into a rigid substance which is solid enough to prevent the flow of air and moisture through gaps it is used to seal. Choose the correct foam for your purposes.

Step 3 – Small Areas

Where there are only minor parts of your property that require insulation for the purposes of sealing cracks, such as around window frames or between floorboards, you will only need a can of spray foam insulation which is available in most hardware stores. Some varieties will have a nozzle attached and ready to be used, whereas others will require the need for an applicator that will often need to be purchased separately. This type of spray foam insulation will react with the air and it will normally comprise a fine nozzle to help you work precisely.     

Step 4 – Large Areas

For larger jobs such as cavity walls and roof insulation, a larger kit will be required that should only be used with protective gear. These kits can look very much like the types used by professionals, including 2 separate pressurized tanks of liquid which mix in a hose that is linked to a spray nozzle. This reaction is often very quick so you should prepare for it and be ready and aimed at the first spot where you want to apply the foam. If possible, test it in an external location first to get an idea of the speed of operation. These foams expand and solidify very quickly so it must be applied correctly.
