Insulation Options
Blown-in Fiberglass Insulation
This efficient insulation method works well in any space and easily fits around the existing features of your home. We install blown-in insulation in House attics, Garage attics, Walls, Floors, ceilings, and more.
Blown-in insulation is a good choice for existing homes because your installer can add it without tearing out drywall or doing any major damage to walls.
It’s also handy for filling in open spaces and gaps to improve energy efficiency and keep cold air out in the Winter and cool down the thermal mass temperatures in the Summer. In addition, blown-in insulation is often used for soundproofing to keep street noise outside.
Batt Insulation
Batt insulation can help insulate your home from the floors to the walls to the ceilings. Typically, it consists of fiberglass or mineral wool batts.
Fiberglass batts are the most common, but what’s suitable for your home may be something different. We customize based on your needs.
This well-known and reliable insulation technique is cut to size and often installed in walls, attics, and basement crawl space sections. It is also one of the most fireproof insulation materials available, making it a particularly desirable option in older homes.
In addition to its fire resistance, when installed by a competent professional, batt insulation can help you save money on your energy costs.

Radiant Barrier Attic Foil
Sometimes called reflective insulation, these barriers are meant to reduce the heat created by sunlight as it beats down on your home. These radiant barriers are usually installed in the attic of your home. Research shows that these components may reduce your cooling expenses by up to 10%.
Radiant barriers are typically made of paper, plastic, or cardboard wrapped in aluminum foil. It’s important to have certified professional insulation installers do the job of putting in the radiant barrier because it must be installed correctly to work effectively.
Spray Foam Insulation
Often applied to ceilings, floors, attics, walls, and basements, spray foam insulation creates an airtight and gap-free barrier that also resists moisture and adheres to all types of surfaces.
As a result, it keeps outside air from coming into your home. Spray foam insulation is usually made from resin, polyurethane, and other components that fill the space and harden quickly to form a durable barrier.
Spray foam insulation has the added benefit of keeping insects and other pests outside since it can fill tiny cracks that different types of insulation can’t reach.
Sometimes spray foam is called rigid foam because of the form the final product takes. It is firm enough that if you spray too much, the installer can cut away the extra material once it dries.

Other Services

Air Sealing
Before you add insulation, it is ideal to seal up any bypasses or intrusions from air that may be getting in. Basic air sealing is included with any insulation project.
Air sealing means that you fill any leaks that let air into or out of your home. It helps reduce the expense of heating and cooling your home, but it also helps your attic insulation last longer and may improve your indoor air quality.
Air sealing usually involves caulking and weatherstripping cracks and the areas around your doors and windows in the attic and elsewhere in the home.
Crawl Spaces & Basements
Attic insulation is essential, and it’s the first thing that comes to mind for most people when you talk about insulation services. However, basements and crawl spaces present a unique challenge for the installer when it comes to insulation.
When left uninsulated, these spaces can be a source of significant energy loss. They can also provide an entry point for insects and other pests. For these reasons, the building codes in most areas require some form of wall insulation.
Looking to make your crawl space or basement warmer or more secure from pests? We do batt insulation, foundation wrap, crawl space encapsulation, and air sealing.

Frequently Asked Questions
You may have heard the term as it relates to insulation, but what does R-value mean to your home’s insulation? R-value is a way to measure how well a particular kind of insulation resists heat flow, also known as thermal resistance. The higher the R-value, the better the insulation is at helping you keep your home comfortable. The American Society of Testing and Materials is responsible for testing and providing the official R-value of different materials. These measurements allow you to compare materials of different weights and thicknesses.
Understanding R-values can help you understand how much insulation your home needs. Of course, the exact calculations for your home depend on where you live, and there are different measurements for your attic, walls, and floors. Colorado building code says you should have at least R-49, or about 16” of fiberglass insulation in a home attic.
All materials of the same R-value are equally good at insulating your home regardless of how they compare to other factors. The installer you work with must thoroughly understand the R-values of the different materials to help you make the right choices.
