Spray Foam Insulation 

Spray Foam Insulation (SPF) is made by combining an isocyanate ( A side ) and a resin (b side) at a 1:1 ratio. Isocyanates in polyurethane is typically made up of methylene diphenyl disoycynate (MDI) and polymeric methylene diphenyl disocynate (PMDI). Resins in polyurethane are usually made up of polyols and catalysts.   Different foams may use catalysts within the foam to help the reaction occur. A common catalyst in spray foam insulation is a blowing agent. A blowing agent is a substance in the foam that produces a cellular structure that effects the way the foam hardens. The common blowing agents used in most foams are water and hydrocarbons based on the foam type. Open cell spray foam insulation usually has a water blown agent and closed cell typically has water and a hydrocarbon which forms the foam. The two components A and B, are then disposed through a proportioning system that evenly distributes the chemicals that are then ran through a hose and mixed through the spray gun. When spraying, the chemical reaction is created to make spray foam insulation that comes out as a liquid and adheres to a surface and expands and sets. Open cell insulation tends to have a spongy like texture, as closed cell insulation is a ridged more tough texture due to its water impermeable properties. Low Density foams are referred to as open cell foams that are used in structures  for insulating purposes.  It is important to follow all foam manufacturers guidelines in regards to handling these products and should always have proper personal protection equipment on when handling these products. It is recommended that a trained and certified applicator handle and process these materials.

Spray Foam Roofing

Spray Foam roofing is a two-component spray applied polyurethane roofing foam that provides insulation, waterproofing and roofing stability. Polyurethane foam roofing has the highest R-value of any commonly used roof insulation. 
This system provides:
►Seamless roof membrane.
►Lightweight.
►No fasteners-fully adhered.
►Easily tapered to eliminate ponding water.
►Tear off is not normally required.
►UL and FM fire and wind rated.
Polyurethane roofs are installed quickly, resulting in a lower labor cost and less interruption.  Spray Foam roofing makes complex shapes easy to spray and can be applied to metal, asphalt, clay and wood roofs.

Spray Foam roofing can withstand extreme weather conditions, but requires a protective coating. Under direct sunlight, the polyurethane will degrade at a rate of approximately 1/16 inch per year.  To protect it from U.V. damage, various types of elastomeric rubber membranes are installed.  Among the membranes used are silicones, urethanes, polyureas, acrylics, and butyls.  These coatings are spray applied over the polyurethane, forming a seamless protective membrane.  In addition to U.V. protection, these coatings provide waterproofing, impact resistance, and improved fire ratings.  Additional membranes include more conventional types such a EPDM, Modified Bitumen, and Built Up. Spray Polyurethane Roofing is designed to be relatively maintenance-free but basic maintenance that requires cleaning and recoats every 10-20 years will help maintain the roofing foam in order to keep the structure properly insulated

Protective Coatings 

Protective coatings can be a single or plural component material that is used for secondary containment, corrosion control, roof coatings, pipe and tank coatings, fireproofing,  marine coatings, waterproofing, manhole and sewer reconditioning and many more. Single component coatings are common in roof coating applications and some fireproofing applicationsboth used over polyureathane foam. Common plural component coatings are epoxies and polyurea. Typically plural component applications may require a primer and include  fast setting and strong chemical resistance. Plural components consists of a catalyst and a resin that become a single coating when mixed together.
