Spray wall insulation also known as spray foam insulation is mainly done with the aid of two particular types of spray foams. This is open cell (polyurethane) and closed cell (isocyannurate). An open cell foam is porous, while its counterpart is not. The closed cell has greater R-Value (term for describing thermal resistance), making wall foam that it forms to prevent formation of mold, which can lead to ill-health.
So how will the insulation work in protecting your home from temperature loss or gain? First, the foam used is applied with the help of a spray gun to fill cracks or spaces in the walls of your home. Once these are filled, air flow out is reduced and loss of cold air or heat is minimized to as much as 10% and even lesser. That is spray wall insulation or even the other insulation types seek to retain temperature in your property.
The foam used in this process is a liquid made from two substances, namely: polymer like isocyanurate and a foaming agent, which makes it swell to nearly a 100 times its previous volume when this is added. As it expands it fills every space or gap that it encounters creating wall foam that compensates for these exit points.
The benefits of this type of insulation are quite much in addition to the health benefit mentioned earlier. First, it makes your home more comfortable since room temperature is regularly maintained; secondly, it adds a permanent structure to your home that will not sag.
Another benefit is that it adds strength to your building structure. Next to this benefit, it also saves cost on energy as you pay less since you will consume less.
Speaking of cost, this insulation type is not cheap as such. The installed cost of sprayed wall foam insulation starts from $1.25 to $2.25 per square foot. Wall thickness and the type of foam determine the prices for this type of insulation.
Spray wall insulation using foam is considered easy by some, but this type of insulation requires you have the requisite knowledge before embarking on it.
Most sprayed wall foam from this type of insulation are environmentally friendly and do not have HCFCs that are dangerous to the earth’s ozone layer. This, however, does not mean you should not carry out a check on substances which constitute elements that make up the insulation materials that will be used in your home.
