More Information
Resolite Tred-Safe was designed to meet the need for a fire rated, strong, safe, walkable+ roof panel. Tred-Safe incorporates the same isophthalic polyester resin as our high performance FS25A and CRFS25A products. The resin is intermixed with a five layer combination of reinforcement including C/W Barriers, bidirectional continuous strand woven and chopped strand fiberglass, making Tred-Safe the optimum FRP walkable panel.
Tred-Safe, type 1645, is Resolite's toughest roofing or siding panel with a nominal weight of 16 oz./sq.ft. and approximately 45% glass reinforcement. This heavy combination of reinforcement, coupled with Resolite's resilient resin, provides a panel that is strong, flexible, and truly walkable. With over ten years of performance history, Tred-Safe has the proven benefit of safely supporting the concentrated load of maintenance workers. Tred-Safe is also ideal as a siding panel where long spans are required or high impact resistance is needed.
Tred-Safe's resin/glass matrix of isophthalic polyester resin and fiberglass reinforcement provides a long service life in corrosive environments and offers outstanding weathering resistance characteristics. The resin's weathering has been greatly enhanced with neopentyl glycol, acrylic modification and UV stabilizers. Resolite takes corrosion resistance and good weathering one step further by providing a C/W Barrier as standard on both exterior and interior surfaces of Tred-Safe. C/W Barrier is the long range solution to better weathering FRP panels and is far superior to highly volatile sprayed on coatings that erode and fade away in a short time.
Resolite Tred-Safe 4.2 x 1-1/16" corrugated profile is an ideal replacement for old corrugated cement panels, since both materials have identical configurations.

More Information
The '40' Series FS25A (translucent) and CRFS25A (opaque) panels were developed to meet a growing requirement for a high strength FRP panel. A combination of glass reinforcement consisting of bidirectional continuous strand woven and chopped strand fiberglass is the ideal solution for longer span capabilities without sacrificing resiliency and impact resistance.
A FRP panel's ability to absorb forces without damage to its structural integrity is critical to long term performance. Straight continuous glass provides stiffer and longer spanning panels which are susceptible to fracturing along the linear glass under continuous cycling and especially foot traffic. The bidirectional continuous strand woven glass provides added strength for longer spans and more evenly distributes stress from cyclic and impact loading thus allowing the FRP panels to maintain their resiliency.
Resolite's unique balance of multiple glass fiber reinforcements and isophthalic polyester resin permits designs which maximize both panel in place performance and load capacity without sacrificing functional requirements.
Resolite takes corrosion resistance and good weathering one step further by providing a C/W Barrier as standard on both exterior and interior surfaces of '40' Series panels. C/W Barrier is the long range solution to better weathering FRP panels and is far superior to highly volatile sprayed on coatings that erode and fade away in a short time.
Resolite FS25A and CRFS25A panels have over 50 years of long term performance history. Both have been utilized wherever fire resistance, corrosion resistance and good weathering characteristics are critical. Installations include steel mills, aluminum production and other nonferrous manufacturing, pickling operations, cooling towers, fertilizer plants, chemical producers, pulp and paper mills, mining operations, water/wastewater facilities and a host of other industrial building applications.

More Information
In the industrial and corrosion market, Resolite and Fire Snuf - FS25A are names synonymous with fiberglass reinforced polymer panels. Resolite started production in 1951 and in 1964 developed and produced the first fire-retardant FRP panel. In accordance with FM Standard 4880, Resolite RFM panels have been approved for unrestricted use as a wall, roof or ceiling without height limitations or sprinkler protection.
Resolite RFM panels also achieved I-90 Wind Uplift Classification and passed the Factory Mutual tough hail damage tests. In addition, Resolite RFM 11, 14 and 17 panels have passed ASTM E 108 and achieved a Class B rating with a maximum 3 in 12 roof slope. The Resolite RFM insulated panel system was also tested and meets the FMRC Class 4453/4420 approval requirements. RFM fiberglass reinforced polymer panels are formulated using the same halogenated isophthalic resin system as used in Tred-Safe and CRFS25A. All FM approved FRP panels must use additives to retard burning; these additives, however, reduce corrosion and weather resistance. When an FM label is not required, Resolite's FS25A, CRFS25A and Tred-Safe would be the superior choice for utmost corrosion and weather resistance. These panels carry a UL25 flame spread rating and are produced with our unfilled isophthalic resin system.

More Information
Acryloy is the translucent and CR-Acryloy the opaque version of Resolite's non-fire retardant (non FR) panels. Both are available in a wide variety of profiles and in many types 1230 through 830 and have a nominal weight of 12 oz. thru 8 oz. per square foot respectively.
Acryloy and CR-Acryloy panels are a composite matrix of polyester resin and chopped strand fiberglass reinforcement. This glass reinforcement is multi-directional and provides equal strength in all directions. Although other types of glass reinforcements, such as linear glass, can provide stiffer panel characteristics and longer spanning capabilities, they sacrifice resiliency. The ability to absorb various forces without damage to its structural integrity is critical to the long term performance of FRP panels.
C/W Barrier is an option available on both exterior and/or interior surfaces of '30' Series panels. C/W Barrier is the long range solution to better weathering FRP panels and is far superior to highly volatile sprayed on coatings that erode and fade away in a short time.
Resolite Acryloy and CR-Acryloy panels have over 50 years of long term performance history. Acryloy and CR-Acryloy have been utilized wherever corrosion resistance and good weathering characteristics are critical. Installations include steel mills, aluminum production and other nonferrous manufacturing, pickling operations, cooling towers, fertilizer plants, chemical producers, pulp and paper mills, mining operations, water/wastewater facilities and a host of other industrial building applications.
