The repair and maintenance of metal roofs has never been easier or more effective. Using on roof seams, fasteners, and other roof joints water tight sealing can be accomplished effectively and economically. Simply apply in a heavy bead over end laps and vertical seams, or in a dollop over defective fasteners is a brush-grade mastic with unique physical properties. Unlike most asphaltic or acrylic coatings, will not crack or become brittle over numerous freeze/ thaw cycles. This unique material actually stretches and recovers to bridge roof joints in which thermal movement can be expected. With 1500 PSI Tensile Strength and 600% Elongation capabilities, can singlehandedly tackle most metal repairs is typically stocked and purchased as white in color. Clear is also stocked for skylight panel restoration. White is U.V. Stable but clear PEB Water Proofing is only moderately U.V. Stable. AIR VENTILATOR Works on centrifugal force created by continous running of vanes. Minimum wind pressure rotates the ventilator on self lubricated Teflon cap. Hot and polluted air escapes, creating pressure drop beneath. Immediately fresh and cool air enters to fill the pressure drop. The fly wheel effect on the ventilator makes it run continuously and fresh air flow is maintained. It prevents entry of water and dust particles. Fresh air makes people more alive and active. Air Ventilator is manufactured with high technology and quality to reduce weight and to increase durability. It is boon to every industry that strives at cost reduction and energy consumption making it economical and environment friendly. Ventilators are available in aluminum and stainless steel in 14” & 24” throat size. Base frames made Dry to touch: 2-3 hours • fully cured at 72°F: 3 days • elongation (ASTMD-412) @ 77 F: 600% • recovery 99% • recovery from 100% elongation (ASTMD-412): 100% • tensil strength (ASTM D-412): 1500 PSI • vapor (ASTME-96): 0.15 • color stability: excellent • resistance to sunlight: excellent • resistance to • weathering effect: slight chalking • adhesion to aluminum (ASTM 3359-80): 5 (highest rating) • adhesion 3359-80): 5 (highest rating) • cold temperature flexibility: excellent • abrasion resistance: excellent. Before applying the roof must be free from grease, dirt, moisture, and all foreign products. Using a power washer works best. But for small repair jobs one could use a out of fiber(in U.V. Stabilized Resin) are available with 4 to 20 slope frames suitable for tile and Trafford color coated sheets, gavalume sheets and another aluminum industrial profiles. Asbestos sheets are also available. Minimum lapping length is 100 mm depending upon the purlin space. ADVANTAGES • Strong Light weight and durable • Only 2 mph of wind velocity is required. • Improves working conditions and increases productivity. • No operating cost since it runs on wind power. • 10 years warranty on the ventilator head. • No noise - Super silent operation. (PEB International can supply special size Turbo Ventilators subject to quality and duration for delivery) brush and water (repeatingly if repair area is properly clean. Remember to let dry before applying . Apply in a temperature range of 40° to 120°F. After application, has a service temperature range of -40° to 180°F.
