Insulating your home is one the most cost-effective ways to make your home more energy efficient and comfortable. Insulation products are rated by effective resistance to heat flow. This is referred to as resistance value or “R-value”. Higher R-value translates to lower heating and cooling bills and improved temperature consistency in the home. Most homes and buildings in north Georgia are built before the 1990 and are poorly insulated—if at all. Current Georgia building code today require minimum levels of insulation. For example, current building code requires R-30 for a traditionally insulated attic and R-22 for sprayfoam encapsulation along the roofline. This equates to 12” depth of fiberglass insulation and 5.5″ of sprayfoam.
ECS will perform an audit to determine the levels, quality, and effectiveness of the insulated areas of your home. Based on your needs and budget, we will make recommendations for the amount and type of insulation and then install it for you.
The most common and least effective insulation in existing homes. It can be installed in walls, floors, or ceiling cavities. When fiberglass batts are installed, it’s very important to secure the batt insulation tightly to the subfloor or walls since batts are ineffective when they sag and air seeps in. While installing batts, it’s important to avoid gaps, voids or compressions – which can further decrease its effectiveness.
Fiberglass Loose fill
Loose fill fiberglass is more effective by than fiberglass batts since it gets into the crevices and gaps that batts tend to miss. Using a special machine, our experienced crew blows the insulation into wall cavities or on top of other types of existing installation to facilitate a more even and effective coverage depth (higher R-value).
Cellulose Loose fill
Cellulose insulation is just like fiberglass but made out of shredded newspaper which is better for the environment. Cellulose is dustier than fiberglass but has a higher R-value at approximately 3.1 per inch.
High Density Sprayfoam (aka closed cell sprayfoam)
Closed cell sprayfoam is the most effective insulation available. Closed cell foam doubles as both and air and vapor barrier adds significant structural strength to any home when it is applied. Closed cell foam will never sag, settle, or lose its R-Value like fiberglass batt insulation is prone to do. Additionally, closed cell foam helps keep bugs and critters out. This type of foam is typically used on subfloors in crawlspaces/basements and along foundation walls to complete crawlspace encapsulation.
Low Density Sprayfoam (aka open cell sprayfoam)
Low density sprayfoam is just like high density foam but it’s not as compact and has more of a spongy texture. This kind of foam is best for attic encapsulation since it is an air barrier but is water permeable so a roof leak will still find its way through the attic to let you know that water is coming through. Open cell foam is also often used in wall cavities since it is an excellent insulator and also serves as an effective sound barrier.
