Benefits of Spray Foam Insulation

Spray foam insulation is a great option if you’re looking to insulate new buildings or improve an existing one.

Foam spray insulation can save you money, even though it is more costly than other types. Due to its ability to insulate better than other fibrous products like fiberglass, spray foam will lower your heating and cooling bills and actually pay for itself over time.

Spray foam insulation has been gaining popularity because of its many benefits over traditional fiberglass insulation. Spray foam has a higher insulation value (R value, and BTU retention) per square inch. This means that less insulation is required to complete the job. Spray foam expands as it is applied, sealing any cracks or gaps that might go unnoticed. Closed cell spray foam insulation is waterproof, which prevents mold, mildew, and and condensation issue. This can be a problem with fiberglass insulation, reduction its effectiveness and causing future health concerns. Closed cell spray foam insulation is also structural. Closed cell foam can increase the strength of a structure by up to 300%, drastically improving strengths of older homes or wide span structures like pole barns.

2 types of Spray Foam

There are two types of foam insulation. You can choose between open cell or closed cell spray foam depending on your needs.

Open cell is cheaper and more porous. It expands for than closed cell foam and is easily trimmed. It does a great job at stopping air flow but does still require a vapor barrier when installed in northern climate zone. Closed cell, on the other hand, is more dense. Closed cell foam provides the highest quality air and vapor seal and also improved structural strength of the building. It does not require a vapor barrier but does come at a higher cost.

Here at TCS, we primarily spray closed cell foam in our climate zones 6 and 7.

Advantages over other types of Insulation

Spray foams biggest advantage is its ability to create and air tight seals. 98% of heat and cooling lose is due to air leakage. This is where fiberglass and cellulose struggle. Spray foam seals up all of your air leakage and keeps the conditioned air inside your home and mother nature out. Air leakage also can cause major condensation issues. When hot air meets cold air, it can condense and create water. This happens right inside your walls and roof. This leads to mold, mildew, water damage, and more. Fixing these issue later can cost 10 times what the added cost of spray foam would have costed during the original construction.

Spray foam also keeps its R value and BTU retention in real world testing unlike fibrous products. Where fiberglass can perform as low as 1/5th is stated R value in real world testing with air and vapor movement, spray foam stays true to is stated r values and continues to perform for the life of the product.
