Spray foam is a much better sealant than fiberglass batts in quite a few ways. It for example not only seals the air but also efficiently insulates it. It also has a rather good R-value and thirdly, it remains the same form after use. In other words, there is no compression or settling due to potentially harmful moisture.
It’s the increased emphasis on energy costs that has hiked the demand and attention on spray foam. Increased heating and cooling costs means that you need to spend more on things like fuel and electricity to maintain a comfortable temperature in your house.
And everyone knows that one of the best ways to reduce energy costs is through insulation upgrades. This is where spray foam fits it, as it’s a viable solution that helps achieve these savings. They are freely available in most hardware retailer shops in small pressurized cans. Professionals are better at handling larger jobs of insulating areas between rafters, joists, and studs. The foam tends to expand immediately once released.
It’s always better to let the professionals at Home Insulators decide if your home is properly sealed to give you maximum energy cost savings. Just call us and we will give you a free estimate and evaluation.
Open cell foam offers better diffusion but with a reduced R-value
The insulation value of open cell foam is an R-value of about 3.5 to 4.0 per inch. It is made connecting tiny little bubbles together while the insulation value stems from the bubbles holding air in them.
Lcynenen is one of the open cell foam brands and is available only from their own contractors. However, its generic brands are made available by independent contractors. An open cell can help close up cracks and gaps by expanding in the same manner as closed-cell foam does.
However as open cell foam soaks moisture like sponges, it tends to absorb moisture and in the process, its R-value tends to reduce when it gets wet. This is why it’s better to avoid using open-cell foam for insulating damp areas like crawl spaces and basements.
While it’s possible to spray rafters and studs, it will not produce that much insulation because of space confinement. It is comparatively cheaper to install open cell foam than closed-cell foam.
Closed cell foam comes with higher R-value and comes with a solid finish and a vapor barrier
You can find closed-cell canned foams in hardware retail stores which are also called single-component foam. This is different from the foam that contractors usually use on large projects which are called polyurethane foam.
It’s through a chemical reaction that takes place in the foam as soon as the chemicals leave the nozzle that leads to foam expansion. While installing closed cell foam costs more, it’s the preferred choice for most projects because of its high R-value.
Besides, closed cell foam tends to form an effective barrier against moisture. It is the three in one combination of the moisture stopping abilities, airtight sealing capacity and high R-value that makes closed cell foam the preferable choice for most applications.
