Spray Polyurethane Foam (SPF) is a two-part mixture, Part A (MDI) and Part B (Resin) which can be open cell or closed cell foam. Trained professionals apply the SPF to the substrate specified for insulation. The spray mixture expands rapidly to fill all cracks and voids; completely and permanently adhering to: wood, masonry, metal, concrete and most other construction materials.

Dynamo SPF and ClimateGard spray polyurethane insulation requires the use of highly technical processing equipment. This equipment is maintained and operated by skilled individuals. We always recommend using installers that have passed tests set forth by the American Chemistry Council and the Spray Polyurethane Foam Alliance.

Closed cell spray foam has an R-value of R-6.7 per inch or higher. Open cell spray foam has an R-value usually of R-3.8 to 4.0 per inch. The materials have different densities and cell structures. Closed cell spray foam has a density of 2lbs/ft3 whereas open cell spray foam has a density of 0.5lb/ft3.

Dynamo SPF insulation should be installed after the proper code inspections of: rough plumbing, electrical wiring and HVAC. If you are sealing the entire roofline the spray insulation may need to be applied in some areas before the ductwork is installed.

Yes. Building codes provide for the use of spray polyurethane foam insulation. Please see Dynamo Spray Polyurethane Systems code evaluation report.

Attic spaces can be insulated by applying foam directly to the underside of the roof deck or to the attic floor. This really depends on how your home is designed. It is common place to apply spray foam right to the roof deck if you have your HVAC ductwork in the attic. This will bring the HVAC ductwork into the building envelope and increase efficiency.

Much research has been done on this topic and there have been many papers written on this subject. Properly installed SPF insulation done according to building code should have no affect of roofing shingles.

Dynamo and ClimateGard closed cell spray polyurethane foam (SPF) is the option. Closed-cell SPF is listed as a Class 5 Flood Damage-Resistant Material per FEMA. These materials can survive wetting and drying and may be successfully cleaned after a flood. More information can be found here .

A frequently asked question. A good home design is to build a house tight and ventilate it right. When you use SPF insulation for the building envelope your home will be sealed very tight. Energy efficient building codes require better building techniques and spray foam helps solve this. It is always recommended to properly ventilate all cooking and bathroom vents to the outside of the home. Depending on your climate zone code will require the proper design and use of an Energy Recovery Ventilator (ERV) or Heat Recovery Ventilator (HRV).
