ColWest Insulation




We offer many other types of insulation to suit every unique project.  If you have a specific type of insulation in mind, please contact us with questions.  Similarly if you have an insulation problem please contact us for a solution.

Blowing Wool Insulation is an unbonded, virgin fibrous glass blowing insulation designed with optimal thermal properties and excellent coverage and blowing characteristics.  Insulation is installed in open attics of both new and existing structures and/or in closed cavity applications with the BIBS system (Blow-in-Blanket System) in which ventilation is not required.  Excellent Thermal Performance the blowing wool fills all gaps and voids, creating a thermal barrier against outside air and better temperature control.  Reduces fuel usage and utility bills for heating and air conditioning.  Blowing wood is non-combustible, non-corrosive, will not rot, grow mildew, or deteriorate.

We use Knauf Insulation Jet Stream ULTRA Glass Mineral Wool. It is a leading blowing wool insulation product and sustainable. Each bag contains the equivalent of over 30 recycled bottles, with a minimum of 60% post-consumer recycled glass content.

Fiberglass Batt Insulation is made from molten glass, usually with 20% to 30% recycled industrial waste and post-consumer content. 

Some fiberglass is unfaced, some is paper-faced with a thin layer of asphalt, and some is foil-faced. Paper-faced batts are vapor retarders, not vapor barriers. Foil-faced batts are vapor barriers. The vapor barrier must be installed toward the warm side.

We use Knauf Insulation EcoBatt®  and this insulation doesn’t look like any insulation you’ve ever seen, but that’s because its natural brown color represents a level of sustainability we've never before achieved.

The color comes from ECOSE Technology; a revolutionary binder chemistry that enhances the sustainability of our products. The “binder” is the bond that holds our glass mineral wool product together and gives the product its shape and brown color. ECOSE Technology is a plant-based, sustainable chemistry that replaces the phenol/formaldehyde (PF) binder traditionally used in glass mineral wool products. Products using ECOSE technology are formaldehyde-free and have reduced global warming potential when compared to our products of the past.

EcoBatt Insulation combines sand, one of the world’s most abundant resources, recycled bottle glass and ECOSE Technology

to create the next generation of sustainable insulation…naturally from Knauf Insulation.

Knauf Insulation EcoBatt Insulation are cost-effective thermal and acoustical barriers for

energy-efficient construction.  Their consistent quality, low dust, and clean-cutting resilient

fibers make fabrication easy and installation fast. The products can be used in new and

retrofit wood and metal frame applications in residential and commercial structures, as well

as in manufactured housing applications.

Spray Foam Insulation is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes drilled in into a cavity of a finished wall.

Polyurethane, the most common type of spray foam insulation.  The two component high pressure system is generally used in new home construction. It is a quick expanding type of spray foam.  Spray foam insulation can be categorized into two different types: open cell and closed cell.  We are a gold star spray foam applicator of NCFI we apply open and closed cell spray polyurethane foam insulation in wall cavities. Certification as a GoldStarSM Applicator means we successfully completed a comprehensive NCFI-led training program, ensuring we are properly equipped to meet and exceed each customer’s needs.

Open Cell is a type of foam where the tiny cells are not completely closed. It is a very good air barrier but does not provide an adequate water vapor barrier. It is much more sponge-like in appearance. It is often used for interior walls because it provides sound reduction. 

Closed Cell foam insulation is much denser than open cell. It has a smaller, more compact cell structure. It is a very good air barrier as well as a water vapor barrier. It is often used in roofing projects or other outdoor applications, but can be used anywhere in the home.  The NCFI closed cell spray foam that we use is naturally able to inhibit the growth of bacteria and fungus (mold).  Insulation that is sprayed in buildings protects against moisture, which provides the benefit of reducing the chance of harmful mold and mildew. Eliminating mold growth reduces the likelihood of rotting wood in a home, and allergic reactions to mold spores.

Spray foam insulation saves on energy costs and lowers utility bills. Studies by the US Department of Energy show that 40% of a home's energy is lost as the result of air infiltration through walls, windows and doorways.  Buildings treated with spray foam insulation typically insulate as much as 50% better than traditional insulation products.

In addition to building temperature and moisture control, spray foam insulation is often used to reduce noise. Foam insulation serves as a barrier to airborne sounds, and reduces airborne sound transfer through a building's roof, floor and walls.

NCFI - We are a gold star applicator for NCFI.  Using their InsulStar® is a closed-cell polyurethane foam insulation. When applied, it expands to fill all gaps and cavities, forming a barrier that aids in blocking air infiltration, noise pollution,

dust, and pollen from entering your home.  And since InsulStar® is formulated with renewable agricultural

resources and uses a state-of-the-art, sustainable blowing agent with zero ozone depletion potential.
