Spray Foam Insulation
Demilec, a Spray Foam manufacturer, is one of the pioneers of the spray polyurethane foam industry, which provides insulation solutions for energy efficient designs. We offer two types of Demilec Spray Foam: Open Cell SEALECTION® 500 and Closed Cell HEATLOK® Soy foam. Both high quality products can be used in most building applications, but the choice depends on the conditions of each installation and the specific needs of the client.

SEALECTION® 500 is a complete insulation and air barrier system that insulates and air seals walls, floors, and ceiling cavities against air movement, including spaces around electrical outlets, baseboards, and where the walls meet windows and doors. This prevents outside air (hot or cold) from seeping through walls causing drafts or condensation. SEALECTION® 500 is spray-applied as a liquid, and expands within seconds to 120 times its volume to fill every nook and cranny providing superior energy efficiency and improved indoor air quality by eliminating air movement through walls. SEALECTION® 500 is a non-toxic spray foam that reduces airborne noise and dust making it the healthy choice for those who suffer from allergies, asthma or chemical sensitivity.

HEATLOK® Soy is the next generation of Spray Polyurethane Foam Insulation that employs an environmentally beneficial technology that provides a solution to the challenges of achieving energy efficiency in a building system while improving performance. A single application creates an air, moisture, and vapor barrier while adding to the structural integrity of the building. HEATLOK® Soy has a unique ecological benefit that recycles plastic waste into a Rigid Spray Polyurethane Foam. This helps to more efficiently utilize the world's non-renewable resources. HEATLOK® Soy can reduce excess waste and energy consumption in buildings by up to 50%. It is applicable in commercial, residential, and single / multi family dwellings. HEATLOK® is most optimally utilized when considered on a systems wide approach.


Batt Insulation
Batts, one of the most common and widely available types of insulation, are composed of flexible fibers, mainly fiber glass. Spun from molten glass and sand, fiber glass is an extremely effective insulating material because tiny pockets of air resist the flow of heat and cold. Batts are available in widths suited to standard spacing of wall studs, and attic or floor joists. They are available with or without facings. Manufacturers often attach a facing to act as a vapor barrier and/or air barrier. A facing also helps facilitate fastening during installation. Batts with special flame-resistant facing are available in various widths for basement walls where the insulation will be left exposed. Standard fiberglass batts have a thermal resistance or R-values between R-2.9 and R-3.8 per inch of thickness.

We also offer QuietZone® noise control batts which are acoustically engineered to absorb sound vibrations within the wall and to control noise in the home. Noise control batts can be installed between interior walls, floors, and ceiling.


Blown-In Insulation
Loose fill insulation, also called "blown-in" insulation, is made of fiber glass and used in new construction and older homes, typically in hard-to-reach areas. Fiber glass loose fill insulation is fed into a pneumatic blowing machine and blown under high pressure through a long flexible hose. Since fiber glass insulation is non-combustible and non-corrosive by nature, fiber glass loose fill insulation offers significant advantages over other loose fill insulation products. It will not settle or lose its energy-saving abilities over time. It does not require the addition of fire-retardant chemicals that can promote corrosion of pipes or wires. It will not rot or decay, support fungus or mold growth, or provide sustenance for insects or vermin.

Firestopping
Preventing the spread of fire is absolutely essential in modern construction. The firestopping products we use are made by Hilti® and Specified Technologies, Inc, which are renown for quality and safety. These products rely on proper design and installation for success in an actual fire. They are used solely or in combination to construct firestop systems that prevent the spread of fire, smoke, or hot gases by sealing through-penetrations and construction joints.
