With insulation playing such a valuable part in your home, spray foam insulation is probably the best investment you can make. After choosing to install spray foam, you must now decide on the most cost effective way to install it in your new house. A contractor can cost you many thousands of dollars to install insulation, but you can buy a home rig so that you can do the job yourself, and save a lot of money at the same time.
About Spray Foam
Spray foam is a pliable foam that expands when it is exposed to air and quickly hardens into a durable product. It has good insulation properties, and as it is used in the walls, as well as the ceiling and other hard to reach places, it is far more efficient than other insulation products. The expansion allows it to fill cracks and crevices, sealing off any air leaks.
The closed-cell foam is sprayed on like paint and it expands to about one inch high.
What Sort of Rig
Some companies sell a number of small DIY, closed cell, spray foam insulation rigs according to your needs. You can buy a small rig that is suitable for a room or two. This is the best option if you are renovating and don’t need to do the whole house.
The largest home spray foam rig costs about $1400 and is suitable not only for your whole house, but is big enough to use if you wish to set up as a small business.
Both of these rigs are easy for a home owner to learn and use. You can spray it on a ceiling, in the wall spaces before you add drywall, over the ceiling, or anywhere else you need it.
Why Closed Cell Foam Insulation
Closed cell foam is much easier to install for a home operator than open cell, as well as being more thermally efficient. It is moisture resistant, which means that it is also mold resistant.
Open cell foam is cushiony soft and has open cells that moisture can penetrate. It has an R-value of around 3 to 4 per inch. This foam must be installed by a contractor, which adds to the overall cost.
Closed cell foam is rigid and strong. It has closed cells that restrict the movement of air and moisture, which gives it the better R-value of around 5.5 to 7 per inch. It is a little more expensive, but the expense is off-set by the reduction in your heating and cooling bills.
Don’t Let Your Rig Go to Waste
After you are finished insulating your home you can use your rig to develop a small business. If the business grows, you can consider upgrading to a professional rig, but the larger home rigs are quite suitable for low volume work. Even contractors sometimes use these rigs for smaller jobs.
Spray foam insulation must be installed between the wall paneling as the house is being finished. Make sure you think about installing it before you need it so you don’t hold up the building work.
