Products Used

Two part two pound polyurethane spray foam:

Two-component system designed to fill and insulate large voids and surfaces. Spray foam has excellent adhesion properties create a continuous air barrier. This quality completes the building envelope, resulting in improved indoor air quality and lower heating and cooling costs. The spray foam we use is fire rated and meets various building code requirements for insulation. EST Insulation primarily uses spray foam when insulating crawl space walls, basement box sill and band joist, basement walls, and new construction projects. All spray foams used by EST Insulation are GreenGuard® certified, recognized for its high indoor air quality designation.

 

Cellulose:

Made from 85% post-consumer recycled newspaper and cardboard. The pulp is ground into a fine, fluffy powder, then treated with primarily boric acid and borax to make it fire resistant and also serves as a rodent deterrent. Compared to other blown-in insulation materials like the commonly used fiberglass, cellulose has a much higher density which makes for a tighter seal blocking air infiltration and serves as a far superior sound deadening material. When installing blown-in cellulose it provides an R-value of 3.8 per inch when open blown and 3.6 per inch when dense packed. EST Insulation primarily uses cellulose insulation when insulating attic, knee wall, and enclosed wall or floor spaces.

 

Fiberglass Batting:

As we stated above blown in cellulose is a far superior insulator that fiberglass, but fiberglass batting does serve an important role with us when insulating common walls. Common walls are vertical walls that are in between living space and none living space. EST Insulation primarily uses fiberglass batting to insulate common walls and access hatches.

 

Roxul Batting:

Roxul stone wool insulation provides superior fire and water resistance for a safer and more comfortable place to live. Exceptional sound absorption and thermal properties that can resists temperatures of up to 2150◦F without burning or melting. Non-combustible stone wool does not promote the spread of flame nor produce toxic smoke in the event of fire. Roxul will not rot or corrode. An inorganic substance, it will not promote the growth of harmful mold, mildew, or bacteria. These advantages are due in part to its water repellency, fast drying properties and low moisture absorption. EST Insulation primarily uses roxul insulation when the space that is being insulated is having moisture problems and if the home owner would like to improve the homes sound proofing.

 

Viper CS: 10 mill, triple-ply, cross woven polyethylene vapor barrier

Crawl spaces are full of moisture that enters via evaporation and diffusion through the floor and sidewalls. An important part of a crawl space moisture control strategy is the installation of a vapor barrier. A vapor barrier provides the crawl space with a moisture and soil gas protection layer that decreases the amount of moisture and radon presence in the crawl space. This greatly reduces the risk for mold, mildew, wood rot, floor failure, decreased insulation R-Values, increased heating and cooling bill, odors, insects, dust mites, aggravated allergies, poor storage environment, and poor indoor air quality. EST Insulation uses Viper on the floor of all of crawl spaces. We use this specific brand because of its high quality. This high quality is necessary because it reduces chances of product damage during installation, it maintains integrity over time under foot traffic and storage, and qualifies as a true vapor barrier.

 

One part fire resistant foam:

Used to air seal smaller thermal bypasses in attic spaces and basement. A bypass is a protrusion between the homes condition and non conditioned spaces. Using one part foam to air seal your homes bypasses is a cost effective way to have your home sufficiently air sealed.

 

Reflectix:

Reflectix is an insulated reflective barrier. EST Insulation primarily uses this product to enclose heat admitting systems in attic spaces such as CAZ units, ducting, and hot water/boiler lines. By doing this correctly it will reduce the rate in which the heat reaching the roof. This then reduces the creation of ice damns and future roof problems.

 

Tyvek:

Tyvek is a breathable wrap that we install to common walls over the installed fiberglass. Tyvek has a higher strength-to-weight ratio than paper, absorbs little or no moisture, is strong and rip-resistant, and is made of environmentally responsible material. If you utilize your knee wall spaces for storage, then this is a necessity.
