Over 50 Million Square Feet Installed
Contractors have successfully used Sprayed Polyurethane Roofing Systems (SPRS) for the past 30 years. Resin Technology Company (RTC Division of the Henry Company) is a leader in the SPRS roofing and coating industry, offering top quality materials and many years of experience. More than 50 million square feet of RTC roofing systems have been installed by qualified applicators in most Western states.
RTC’s durable and reliable Permax roofing system has proved ideal for industrial, commercial and residential applications and this unique insulating system maintains millions of square feet of wine and heated fuel oil storage tanks at temperatures just right for their content.

Dual Protection Against Leaks
The primary function of a roof is to keep moisture out of the building. The RTC Permax system assures a double layer of moisture protection.
First, a layer of closed cell polyurethane foam forms a thick, seamless barrier to prevent water penetration.  Then, an elastomeric coating forms an additional shield against moisture and offers protection from the intense rays of sun.  If the elastomeric coating becomes damaged, the layer of the closed cell foam will still resist water penetration and migration.
This unmatched dual protection makes the Permax System a leading choice among building owners and specifiers.

RTC Advantages
RTC offers other important advantages besides quality materials and long experience.

• A Seamless System
Unlike conventional built up roofing systems, the Permax Systems has no seams or laps where leaks often develop.  In fact, a permax roof is self-flashing, effectively sealing all penetrations and wall junctions.

• Reduced Energy Costs
Remax (SPRS) is one of the most effective insulation materials available today.  The material’s insulating properties are further enhanced by the system’s special elastomeric coating which effectively reflect the sun’s rays. Users have reported reductions in energy costs as great as 30 percent.
Permax insulation on wine or oil tanks returns the owners investment over time by reducing operating expenses.

• Lightweight
A Permax roof weighs approximately 100 pounds per 100 square feet, compared with tar-and-gravel roofing which may weigh as much as  800 pounds on the same area, or with a ballasted single-ply roof which may weigh as much as 1,000 pounds per 100 feet.

• Easy Maintenance
When a leak occurs in a built-up or single-ply roof, water may travel some distance between piles before it enters the building, making it difficult to locate the source of the leak. Rock, finishing or ballast may further hide the source. Water may not travel laterally through a Permex roof and any minor mechanical damage can be quickly repaired using an appropriate elastomeric caulk.

• A Faster, Cleaner Roofing Job
A Permax roof for even a large and complex project can be completed in a very short time and with minimal interference in normal business activity. In many cases, a Permax roof may be applied over the existing roof, avoiding a costly ‘tear-off’ and disposal.

• Design Flexibility
A Permax roof easily conforms to unusual shapes and configurations such as domes and curved concrete decks. Several municipal sports arena have specified (SPRS) Roofing systems because of their light weight.
A Permax application adheres to a vertical surface and fills in low areas in an existing roof structure.

• Metal Roof Applications
A leaking metal roof is well known to be a tough roofing problem. A conventional metal roof or coating often leaks because of the expansion and contraction of the metal with changing temperatures.
Because a Permax roof insulates from the outside expansion and contraction are eliminated, thereby reducing stress and wear. Condensation and resulting corrosion on the underside of the metal roof is also eliminated or reduced by the external insulation. Many metal agricultural buildings are protected by Permax roofs.

• Approvals
Many Permax roof systems have been tested for fire safety and are listed by the Underwriters’ Laboratory, Factory Mutual Research Corporation and various model building codes list these roof systems over both combustible and non-combustible decks.
For a complete listing of approvals, contact Skytop Inc., (480) 951-9750.

• Qualified Applicators
Your confidence in a Permax roof is assured by the qualified applicator. A Permax applicator is backed by RTC warranty programs available to owners of larger commercial and industrial buildings.

• Why choose a Permax Roof?
A Permax roof is a monolithic, seamless structure that adheres to horizontal, vertical and over head surfaces. It is self flashing, fills and seals small open spaces, and fills low areas caused by roof sagging or construction faults. Plus, it provides insulation that can substantially reduce energy costs. You can specify a Permax roof with confidence.

Installs in Four Easy Steps

1. Prepare the Surface
Remove all loose gravel and dirt by using a power vacuum and power broom. Remove any blisters in the existing roof. Then prime all surfaces to receive polyurethane foam insulation.

2. Apply Permax Foam Insulation
Spray apply a layer of foam to specified thickness. Spray flashings and penetrations according to RTC’s guide specifications.

3. Spray Apply the Permax Elastomeric Coating
Spray the tough, elastomeric coating onto the foam surface. To insure uniform and complete coverage, the coating is applied in two coats using contrasting colors.

4. Apply Roofing Granules (Optional)
Finally, spread a layer of roofing granules onto the wet elastomeric topcoat to provide additional durability and sun resistance. Walk surfaces may be installed at this time to protect the roof around equipment installations and roof landing areas.

Advantages of Foam (Polyurethane) Roofing

1. SEAMLESS - Sprayed polyurethane foam forms a seamless insulated roofing system.  It has no joints or seams to allow water and air to pass through into the building.
2. ELIMINATE LEAKS - Polyurethane foam conforms to the substrate when sprayed, and is ideal for flashing parapet walls, roof penetrations including vents, pipes, stacks, skylights, and roof mounted equipment such as HVAC and evaporative coolers.
3. ELIMINATE PONDING - Foam can be sprayed in varying thicknesses to build up low areas and slope a roof to aid in drainage.  This can eliminate water ponding and the additional load factor caused by water accumulation.
4. LIGHTWEIGHT - Polyurethane foam weighs approximately 2.7 pounds per cubic foot.  One inch of foam with elastomeric topcoat weighs approximately 60 pounds per 100 square feet.  In comparison, a typical four-ply built-up roof system weighs ten times as much.  This makes foam an ideal system for re-roofing, since in many cases it can be applied directly over an existing roof.
5. CHEMICALLY STABLE - Foam is odorless, resists attack by mildew and fungi, and has no nutritive value.  It is an inert substance, but must be protected from sunlight by a U.V. resistant elastomeric coating.
6. MINIMIZE THERMAL SHOCK - Because polyurethane foam is seamless, has a high "R" value and is covered with a reflective elastomeric coating, it reduces the extent of thermal shock and expansion/contraction a building is subjected to due to fluctuating temperatures.  Foam can withstand structural expansion/contraction without separating from the roof surface.
7. VERSATILE - Polyurethane foam can be used on both new and replacement roofs, including flat, pitched, domed, saw-toothed and those having unusual slopes and configurations.  It conforms to the roof surface.  It is also ideal for spray application to tanks, coolers, freezers, ductwork and piping.
8. RIGID - Polyurethane foam is lightweight and adds strength to the roof system.  It will not pack down or sag like other roofing and insulation materials.  It can be walked on with tennis shoes or other soft-soled shoes.
9. DURABLE - Periodic application of additional coats of U.V. resistant elastomeric coating will ensure that a foam roof provides years of service.
10. EASE OF APPLICATION - Sprayed polyurethane systems can be applied in a relatively short period of time with minimal or no disruption to building operations by an experienced and qualified contractor.
11. EASY MAINTENANCE - In-house maintenance personnel can easily make minor repairs and modifications to a polyurethane foam system using a caulking gun and a tube of caulk.
12. SOUNDPROOFING - Foam aids in soundproofing, resulting in a quieter interior.
13. INSULATION - Sprayed polyurethane foam provides more thermal resistance with less material than any other form of insulation.  It has an aged "R" value of 6.2-6.5, and can pay for itself in just a few years by reduced utility costs.  The elastomeric coating adds an additional "R" value of approximately 3.0 (due to reflectance from a light color).
14. WATERTIGHT - Protected by U.V. resistant elastomeric coating, seamless foam roof systems resist penetration of water and vapor.
