A to Z Coatings

Spray Insulation...

A to Z Coatings installs spray-in-place foam insulation for a wide variety of applications. We use open-cell and closed-cell, each having different characteristics but both providing insulating qualities to give a potential energy savings of 20 to 40 percent.

Open-cell foam is a low density material weighing about ½ pound per cubic foot. It provides and R-value of about R-3.5 per inch along with an air barrier which significantly add to the heating/cooling efficiency of a home or business. Open-cell foam can insulate walls, ceilings and attics. It can be used for all types of building construction and certain brands are recommended by the American Lung Institute for improving indoor air quality. Open-cell foam significantly minimizes unwanted sounds that can invade living spaces, creating a much more enjoyable indoor environment. It helps to reduce noise levels that originate from within building structures (like home theaters and children's play areas) as well as those that originate from the external environment (such as street traffic or airports).

Closed-cell foam insulation is light weight, about 2 pounds per cubic foot. It provides R-7 per inch; unlike conventional insulation, it provides an air barrier at one inch and a vapor barrier at two inches. Because of its density, closed-cell foam improves the structural strength of walls and increases the racking strength of roof sheathing and trusses when used in the attic. It stops air leaks by filling gaps and cracks and can prevent moisture damage and premature deterioration of building materials.

A to Z Coatings also retrofits existing homes by changing the attic space from a vented attic to an un-vented attic. This assembly is created by eliminating ventilation openings and moving the thermal, moisture and air control boundaries to the plane of the roof deck. An un-vented attic system is beneficial because air movement between the attic and the living space does not contribute to energy waste; the load on the mechanical equipment is significantly reduced because ductwork leakage will occur to or from the conditioned living space; leakage from roofing will not cause damage to the ceiling or create the potential premature structural failure or mold growth; and in coastal climates wind driven rain will not be blown in through these openings creating similar damage.
