There are many types of spray foam insulation. Spray foam insulation is a superior insulation compared to conventional batt and blown insulation. NuVision Builders utilizes a closed-cell, spray foam insulation to competently seal the entire attic from any outside environment. A closed–cell spray foam insulated structure is impermeable to air and water while providing the tightest seal possible throughout the entire roof system.
By eliminating air infiltration from the outside of the tight shell, the estimated effective R-value of the roof system can achieve an R-value of 62. In comparison, outdated batt insulation applications typically achieve an R-value of 30. Conventional batt insulation can begin to deteriorate from the date of installation.
In review, use of a closed-cell, spray foam insulation application creates a super-tight, super-strong truss and sheathing system and keeps the attic cool and dry by constructing a superior exterior envelope using solid, reinforced concrete walls, solid eves and solid soffits and by insulating above the attic.
The high performance green building methods results in substantial energy cost savings year over year. For example, by moving air through ducts in a cool and dry attic the HVAC system works far more efficiently and does not cycle as often as conventional HVAC systems.
Utilizing NuVision Builders’ green building design features, air handlers are mounted in the cool and dry attic which reduces sound transmission compared to utilizing a closet inside the home to stack an air handler which is not only a waste of living space but creates a recurring noise problem each time the HVAC cycles inside the closet insider your home. An air handler that is mounted up in the cool and dry attic area is far more accessible for maintenance and repair as compared to an air handler stacked tightly inside a living area closet.
