PRODUCTS & TYPE INSULLATION SERVICES

Spray Foam Insulation is an innovative solution that offers home and property owners customized designs and seals for their new construction or renovation projects. This unique product, also known as spray polyurethane foam (SPF), provides powerful insulation benefits in multiple applications. Spray polyurethane foam is a chemical product composed of iso and resin, which expand to 100 times their liquid volume when mixed. The expanding foam provides an alternative to traditional insulation that offers better coverage and a higher R-Value – thermal resistance to heat flow, or more effective insulation. Varying densities of spray polyurethane foam offer different R-Values.

Fire Seal

FIRESTOPPING PROTECTION

Firestops are designed to restore the ratings of a wall or floor assembly, impeding the spread of fire and smoke by blocking openings with fire-resistant materials. Even if a wall is fire-resistant, horizontal or vertical penetrations in the wall can diminish its resistance and allow the rapid and wild spread of smoke and fire. Firestopping seals these penetrations at joints and junctions to ensure fire resistance. We offer the top premium-grade Insulation installation services to suit any size and budget. Our team of Insulation experts and Professional installers can install, replace, or upgrade your all insulation needs.

Types of Insulation

THERMAL AND ACOUSTIC INSULATION

R-value requirements also vary based on the spot in your home in which the insulation is installed. When it comes to the best insulation for walls, the insulation material can also impact the R-values needed for good energy efficiency.

Insulation materials include:

Fiberglass: Fiberglass is the most common insulation material. It’s made from fine glass fibers and is most often used in batts, rolls and loose-fill insulation. Fiberglass is a skin and lung irritant, so always wear protective eyewear, gloves, masks and clothing when working with fiberglass insulation.
Cellulose: Cellulose insulation is made from recycled paper products. Manufacturers also add borate for fire and insect resistance. Cellulose insulation is usually a loose-fill insulation.
Foam: Foam insulation may be made from polystyrene, polyisocyanurate or polyurethane, which are all types of plastic. You can also install cementitious foam insulation, which is cement-based. Foam insulations can be sprayed or installed in rigid foamboards.
Mineral wool: Mineral wool can refer to either rock wool or slag wool. Rock wool is a man-made material made from a combination of natural minerals. Slag wool is also a man-made material, but is made from a waste product of molten metal known as slag. Both mineral wool insulations are naturally fire-resistant. They come as batts, rolls and loose-fill.
Natural fibers: Insulation can also be made from various natural materials, including cotton, sheep’s wool, straw and hemp. Typically, these materials are from recycled sources and are treated to be fire, mold and insect resistant.
Denim: Denim insulation is made from recycled jeans and post-industrial denim cotton. Denim is non-toxic and non-irritating, making it easy for DIYers to install. It’s typically more expensive than fiberglass or other insulation materials.
The most common insulation materials are fiberglass, cellulose and foam. Home insulation types include any of the above materials in the form of loose-fill, batts, rolls, foam board, spray foam and radiant barriers.

Loose Fill Insulation

Loose-fill insulation, also known as blown-in insulation, is blown or sprayed into place with special equipment. You can rent an insulation blowing machine to install this insulation yourself, but most choose to leave this installation to professionals.

Best for attics, hard-to-reach or oddly shaped areas and already insulated areas.
Usually made of fiberglass, cellulose or mineral wool.
Blown or sprayed into place with pneumatic equipment.
Can fill wall cavities.
Mid-range prices when compared to other insulation types.
R-values range from R-2.2 to R-3.8, depending on the insulation material.

Insulation Batts

Batt insulation is a type of insulation blanket. These are pre-cut sections of insulation that are usually fiberglass, although cellulose, mineral wool, natural fibers and plastic versions are also available.

Best for unfinished walls, floors and ceilings.
Designed for easy handling and use between framing, such as studs and joists, making it among the best insulation for walls.
Installed in pieces.
DIY-friendly.
One of the most affordable types of insulation.
Available either with or without paper or aluminum foil facing. Facing helps prevent interior heat from escaping and water vapor from passing through the insulation. Install the batt so that the facing is the exposed side.
Standard fiberglass batts have R-values ranging from R-2.9 to R-3.8 for every inch of thickness, but high-density insulation batts can have R-values as high as R-4.3 per inch.

Rolled Insulation

Rolled insulation is another type of insulation blanket similar to batt insulation. The main difference between insulation batts and rolls is that batts are installed in pieces, while rolls are rolled out between wall and ceiling framing. Insulation rolls leave less opportunity for gaps between sections, making them sometimes more effective than batts.

Best for unfinished walls, floors, ceilings and wherever long and continuous insulation pieces are needed.
Available in pre-cut widths to fit between studs and joists.
Come in continuous lengths ranging from 20 to 40 feet.
DIY-friendly.
Another one of the most affordable types of insulation. Comparable in price to batts.
Like batts, standard fiberglass rolls have R-values ranging from R-2.9 to R-3.8 for every inch of thickness. High-density insulation rolls can have R-values as high as R-4.3 per inch.

Foam Board Insulation

Foam board or insulating boards are rigid panels of insulation that have a high R-value. Because they have a high R-value and can be used nearly anywhere in your home, foam board insulation is one of the most common types of insulation.

Best for floors, foundation and basement walls, interior and exterior wall sheathing and low-sloped ceilings.
Can be used to insulate almost any part of your home, from the roof down to the foundation.
Usually made from polystyrene, polyisocyanurate or polyurethane.

Spray Foam Insulation

Spray foam insulation is a liquid latex or polyurethane foam that expands and hardens to fill gaps. For large insulating jobs, professionals spray this insulation into place with special equipment. For small sealing jobs, spray foam is available in spray cans.

Best for hard-to-reach or oddly shaped areas and already insulated areas.
Can be used to fill small gaps and cracks or to insulate large spaces.
Ideal for sealing around doors, windows and vents.
Sets quickly and can be trimmed, painted or stained.
Has two types: open-cell foam and closed-cell foam. Closed-cell foam is denser and thus has a higher R-value. Closed-cell foam is usually more expensive than open-cell foam.
Open-cell foam has an approximate R-value of R-3.7 per inch of thickness.
Closed-cell foam has an approximate R-value of R-6.2 per inch of thickness.
Sheathing reduces heat conduction through structural elements like wood and steel studs.
Great insulation choice for cold climates.
DIY-friendly.
Typically more expensive per square foot than other insulations.
R-values range from R-4 to R-6.5 per inch of thickness.

Radiant Barriers

A radiant barrier is a type of insulation that reflects heat away from your home instead of reducing the flow of heat out of your home, like most other insulations.
Best for attics, unfinished walls, ceilings, floors and attached garages in hot climates.
• Designed to keep your home cool.
• Made from a reflective material such as aluminum foil over a substrate like kraft paper or foam board.
• DIY-friendly.
• Most often used for attics, since most heat enters through the attic.
• Not measured in R-values.

Vapor Barriers

A vapor barrier is a material that prevents water vapor from passing into your walls and ceilings during cold weather. If moisture from either direction builds up within stud or cavity walls, the heat-conducting moisture will cause the insulation to lose its R-value. Mold and rot can also set in over time.

Best for interior and exterior walls in cold or humid climates, especially for homes with masonry or wood walls.
House wraps and kraft-faced insulation are examples of vapor barriers that help control the amount of moisture that passes through the insulation.
Most used when framing the exterior walls of a house.
Installed after insulation.
DIY-friendly.
Not measured in R-values.
