With ever increasing costs of energy, proper home insulation
is essential to ensuring long-term comfort and value.

Insulation has significant sound proofing benefits that add peace and quiet to a personal residence or commercial structure. When selecting an insulation material, the most important environmental consideration is its performance and suitability for your application. SDI Insulation’s experienced staff will guide you through choosing the right insulation for your residential or commercial applications.

Blown Insulation


Blown Insulation is one of the most cost-effective energy conservation measures you can take.

Loose Fill Blown Mineral Wool Insulation offers completely uniform coverage, especially in hard-to-reach attic areas. Because covering is so complete, blown-in materials become an excellent thermal blanket, leaving no nook or cranny exposed for heat to escape.

At SDI we use Premium Blown Mineral Wool Insulation which must be pneumatically installed by a professional contractor – such as SDI Insulation – who is trained and qualified to evaluate insulation needs based on climate and energy standards for the area. This is used primarily in attic applications.

SDI provides you with only the best blown insulation products, chosen based on these key features: Loose Fill Blown Insulation can increase a home’s energy efficiency and help reduce costly heating and cooling loss. It is permanently noncombustible. Unlike cellulose products that contain sulfates, it will not corrode pipes or wiring. When installed in interior and exterior walls, this improves the acoustical performance of the wall assembly.

Blown Mineral Wool Insulation contains no additives that can cause noxious fumes or odors. It won’t absorb and retain moisture that can cause deterioration. Because this is made of glass fibers, it contains nothing to provide sustenance to insects or animals. It complies with federal and local building standards and qualifies as a Type I insulation under ASTM C 764. It has been tested and verified in accordance with approved test methods by recognized independent laboratories in Canada and the U.S. And finally, our Blown Mineral Wool Insulation is GREENGUARD® Certified for superior indoor air quality performance.

SDI is your Blown Mineral Wool Insulation specialist, providing you with top of the line, environmentally responsible products and quality job performance.

Spray Foam Insulation


Spray Foam Insulation expanding foam is an environmentally safe development in low density, cellular plastics.

Once in a while, a new construction material or method comes along that not only complies with all code requirements, it’s capable of raising the standards. Spray Foam Insulation has been making a profound change in the perceptions of insulation’s role in commercial and residential construction for over a dozen years.

Chemically, it is in a class of its own. It allows foam to be sprayed without ozone destroying gases (HFA’s or HCFC’s) or formaldehyde. The micro-cells of this breathing material are filled with air and there are no gas emission hazards.

Spray Foam Insulation is not just an environmentally responsible insulation system, it insulates and air seals.

Building scientists have recognized that air leakage has a greater impact than R-value on the performance of a building. Spray Foam Insulation is becoming the industry standard for providing maximum building envelope performance. Spray Foam’s pour and spray formulations represent a breakthrough in the science of moisture and thermal management.

Spray Foam Insulation is the leading 100% water-blown foam insulation that minimizes air leakage for increased energy efficiency (often as high as 50% of conventional costs), creates a healthier indoor environment, reduces airborne sounds and offers greater design freedom. Spray Foam maintains its performance with no loss of R-value over time. It does not shrink, sag or settle. Spray Foam adheres to most construction materials and is the perfect insulation for walls, attics, ceilings and floors.

Our sales staff is constantly being trained at seminars and conventions, and awaits the opportunity to explain the numerous benefits of Spray Foam Insulation. Please contact either of our offices, or submit an estimate request online.

Spray Formula

Applied as a liquid, Spray Foam expands to 100 times its volume in seconds to fill every crack and crevice while remaining flexible so that the integrity of the building envelope seal remains intact over time.The spray formula has an R-value of 3.6 per inch. It acts as a complete insulation and air barrier to minimize air leakage and seal the building envelope for optimal air tightness.


Cellulose Blown Insulation


Cellulose is “green.” It’s made of 80% post-consumer recycled newsprint.

The fiber is chemically treated with non-toxic borate compounds (20% by weight) to resist fire, insects and mold. The Cellulose Insulation Manufacturers Association (CIMA) claims that insulating a 1500 ft2 house with cellulose will recycle as much newspaper as an individual will consume in 40 years. If all new homes were insulated with cellulose this would remove 3.2 million tons of newsprint from the nation’s waste stream each year. There’s room to grow. Fewer than 10% of the homes built today use cellulose. Cellulose earns “green” points because it requires less energy than fiberglass to manufacture. Disciples claim 200 times less petro-energy than fiberglass. More realistically, Environmental Building News reports that fiberglass requires approximately 8 times more energy to make when adjusted to reflect energy cost per installed R-value unit.

Cellulose insulation is safe.

It is made of paper, but the chemical treatment provides it with permanent fire resistance. There’s been static generated by the fiberglass industry warning that cellulose could burn. But independent testing confirms it’s safe and cellulose is approved by all building codes. In fact, many professionals consider cellulose to be more fire-safe than fiberglass. This claim rests on the fact that cellulose fibers are more tightly packed, effectively choking wall cavities of combustion air, preventing the spread of fire through framing cavities.

Fiberglass Batt Insulation


Fiberglass batts are high-quality flexible products made from mineral fibers and are used in construction applications for thermal and acoustical insulation of walls, ceilings & floors.

Unfaced insulation is manufactured in increased widths to permit frictionfit installation in wall cavities. They are available in widths suited to the standard spacing of wall studs and attic or floor joists, and the continuous rolls can be hand-cut and trimmed to fit. Batts are also available with vapor retarder facings, such as CertainTeed’s MemBrainTM and The Smart Vapor Retarder. Batts with a special flame-resistant facing are available in various widths for basement walls where the insulation will be left exposed. Kraft Faced insulation is manufactured with an integral vapor retarder. Theb kraft facing includes attachment flanges at the edges that are used for either face or inset stapling. The kraft facing, applied with asphalt to the fiber glass insulation, has a vapor transmission (permeance) rating of one perm or less.

At SDI we use CertainTeed Standard Fiber Glass Building Insulation, which is a thermally and acoustically efficient inorganic insulation used for the entire home or office building. It is lightweight and flexible which makes for a quick installation. Because this fiber glass is inorganic it is noncombustible, noncorrosive and will not deteriorate or absorb moisture. And because it is a higher density fiberglass it provides added energy savings to any building. As with all CertainTeed products, fiber glass batts are GREENGUARD® Certified for superior indoor air quality performance.

SDI’s highly experienced sales team is here to help you determine the best insulation system for your residential or commercial project. We will work with your budget and plans to provide you with superior thermal and acoustical performance.

Insulation Removal

When time, water, rodents, or even live animals are introduced to your crawl or attic space, the outcome often results in damage.

When this happens, you will need removal of insulation, vapor barrier, sanitizing, exclusion, ventilation, and an install of new insulation & vapor barrier, or other materials.

The removal of insulation is done in a variety of clean and efficient ways. This service is not recommended for the “do-it-yourselfer” as there are multiple diseases associated with rodents and live animals.

SDI Insulation will use state of the art equipment that moves the insulation from your attic into a filter bag which is located in the back of our vehicle. All materials removed by SDI Insulation are properly disposed of at a local transfer station.
