Are you building a new home, or are you in the market to build a new home? First off, congratulations! While you have some work ahead of you, this is going to be truly exciting and memorable time. If you’ve been here before, chances are, you’ve read why having an Insulation Contractor, rather than just having a General Contractor. If you haven’t, you can find it here.
Should you decide, with this newfound information, that you want to hire an Insulation Contractor to meet your needs on this new project, here is some of the main areas of a home where we are able to meet customers distinct needs throughout most homes:
Here are four main areas of the home insulated with both open and closed cell spray foam: the attic, the roof, the subfloor, and the walls. Different areas of the home require different applications.
Attic – Or Ceiling Bed
Open cell spray foam can be used on the ceiling bed of an attic just like traditional insulation. Open cell’s soft, dense material is able to fill any cracks or spaces in the attic, which creates an air barrier between the attic and the conditioned living space. This allows your new construction to have a significantly higher R-value and greatly lessens heat transfer. Aside from the cheaper less effective ways using batts or blown in loose fill cellulose, spray foam does not deteriorate, shrink or support mold growth.
Insulating the underside of the roof deck ensures that the spaces between the roof deck and rafters are fully sealed. This method completely takes the heat load not only off of the roof deck but completely out of the attic space completely. This is the most effective application with spray foam and further improves the energy efficiency of your new home.
While insulating a subfloor may seem insignificant, it is actually quite important. Not only does it increase the R-value of your home by preventing the escape of cool air, it also aids in moisture management. According to LSU’s AgCenter, “The key to preventing growth of mold and decay…is proper moisture management.” The AgCenter further states that in an experimental study of homes in flood hazard zones, only the homes with “…rigid foam and closed cell…foam exhibited good performance, keeping subfloor moisture content within acceptable levels.” So in addition to improving the ability of these homes to regulate internal temperatures, closed cell spray foam application also provides an additional layer of moisture management.
Insulating the walls in a new construction with spray foam is quite easy. As a matter of fact, in most jobs, we were able to finish so quickly days contractors can begin installing the drywall almost immediately after. For the same reasons open cell spray foam is an excellent option for attics in most homes, it can also be an excellent option for the walls. Open Cell spray foam expands and contracts in a sponge-like manner, and it provides a complete air barrier. Each inch of open cell spray foam provides an R-value of 3.5-4 in each inch installed.
The bottom line is, in order to create the most comfortable, energy efficient, and structurally sound living space, adding a customized spray foam installation to your construction job is a no brainer!
