Inch for inch, polyurethane foam is the leader in insulating foam! Spray-applied closed cell polyurethane is seamless, lightweight, self-flashing, and water resistant and reduces energy costs when applied to roofs of various contours.

Spray-applied rigid polyurethane foam roof insulation provides a tough, weatherproof roof and insures lasting performance in the most severe climates, practically eliminating roof maintenance.

Rigid polyurethane foam demonstrates versatility both through its physical strengths and mechanical properties. These qualities enable it to be used in a wide variety of multi-functional building products which combine insulation with load-bearing, sealing, impact resistance, weight and space-saving, together with ease of maintenance.

Low thermal conductivity

Rigid polyurethane foam has one of the lowest thermal conductivity ratings of any insulant, which allows efficient retention of heat or, alternatively, maintenance of a refrigerated or frozen environment. Effective insulation in all types of buildings plays a vital role in the conservation of non-renewable fossil fuels, which reduces emissions of carbon dioxide gas released by the burning of fuels for energy and therefore reduces global warming.

Insulation is rated in terms of thermal resistance (R-value) which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness. POLYURETHANE FOAM has the highest R-value (7 per in.) of all readily available, cost-effective insulation available in the market today.

Adhesion

During the short period between mixing and final curing, rigid polyurethane foam is extremely adhesive, which allows it to bond effectively with a wide range of building facings. The adhesion is so strong that the bond strength is usually higher than the tensile or shear strength of the foam.

 

Seamless

Polyurethane foam is applied as a liquid, creating a single monolithic membrane that covers the entire roof. There are no seams or joints, the source of the majority of leaks in traditional roofs.

Breathable

While polyurethane foam's closed cell structure is impervious to liquid water, water vapor can diffuse through the foam, eliminating moisture vapor traps.

Water absorption

The water vapor permeability of rigid polyurethane foam is low and is enhanced in most building applications by the incorporation of a moisture barrier of polyethylene film or aluminium foil.

Waterproof

If you own or are responsible for a flat roof structure then you will be familiar with the many problems associated with this type of roof. Standing or pounding water will eventually compromise the protection of many roofing systems.

Strength

Rigid polyurethane foam provides a high level of compression and shear strength, which is further enhanced by bonding with facing materials such as metal or plasterboard.

Processability

Rigid polyurethane foam can be made either under continuous block or batch factory production, or by on-site mixing for spray and injection purposes.

Slated & tiles protection of roof

By under spraying the underside of a slate or tiled roof, the slates or tiles become strongly bonded together, sealing all cracks and gap's, making the roof completely waterproof. The roof is now better insulated and made much stronger without adding any weight. Slates or tiles will never again slip or become dislodged.

Compatibility

Rigid polyurethane foam is compatible with a large number of building facings, including paper, foil, glass fibre, aluminium, plasterboard, plywood and bitumen. These can complement the inherent strengths of the foam, enabling use as semi-structural panels and cladding and allowing foam to accept cosmetic finishes such as plaster to operate effectively as moisture barriers in conditions of high humidity.Rigid polyurethane foam can be used in applications which experience exceptional extremes of temperature, from -200°C to +100°C.

Fire properties

Like all organic building materials - wood, paper, plastics, paints - rigid polyurethane foam is combustible, although its ignitability and rate of burning can be modified to suit a variety of building applications and it can be formulated to meet the relevant national regulations.

Rigid polyurethane foams are usually used at lower thicknesses than other insulants, which means that their heat or fuel contribution to a fire is low compared to other, thicker insulating materials. The overall fire performance of an insulation panel can be significantly enhanced by the material that is used to face the panel - for example, steel. Independently monitored, large-scale tests of buildings incorporating rigid polyurethane and polyisocyanurate (PIR) foam insulation carried out in the USA and Europe have concluded that, properly used, these materials do not add to the severity or serious hazard of fires.

Lightness

Complete polyurethane foam systems are typically many times lighter than tar and gravel roof systems. When applied to an existing roof, the loose ballast that is removed usually weighs more than the replacement foam system. This results in the new roof being lighter than the original.

Chemical resistance

Rigid polyurethane foam provides excellent resistance to a wide range of chemicals, solvents and oils.

Energy-Efficient

Polyurethane foam is specially formulated with enclosed cells, which makes it one of the best insulating materials on the market today. This translates into drastically reduced energy costs for you. The foam is so efficient; it is being used by NASA to insulate the external fuel tanks on the space shuttles.

Recovery of Cost

Polyurethane foam is the most efficient form of thermal insulation available. The systems usually pay for themselves in 2 to 6 years in energy savings alone.

Environmental

Every component that foam replaces, every time it reduces the weight of a finished product, and every time a designer exceeds minimum thermal insulation requirements in a cost effective way, results in an environmental benefit. Better insulation typically results in less energy use. Less complicated and lighter weight products are usually produced using fewer manufacturing steps, less energy in manufacturing, and less energy in transportation. The energy conservation achieved by insulating and sealing a building effectively helps to reduce CO 2 emissions associated with the burning of fossil fuels. For all these reasons, rigid polyurethane foam can contribute to the creation of a more sustainable society and culture by conserving resources today.
