An economical solution for weathertight penetration seals
RPS Alumi-Flash Flashing Systems are a economical and weathertight solution to routing pipes through a roof. The RPS Alumi-Flash System is designed to allow for both vertical and horizontal pipe movement, yet provide a maintenance-free permanent installation which accommodates round pipe sizes of 3/8" up to 12". The key to the effectiveness of the Alumi-FlashSystem is the spun aluminum base and cap. The spun aluminum base is seamless and .060" thick for strength and resistance to damage. Integral to the base is a beaded collar with sealing rings which mechanically locks the flexible cap to the base creating a Weather-Tite Pressure Seal. The flexible rubber caps are molded of time-proven EPDM rubber which is resistant to deterioration from both ozone and ultraviolet rays of the sun with a serviceable temperature range of -60°F to +250°F. The conically-shaped steps of the nipple(s) provide a taut waterproof seal around the pipe(s) and the furnished stainless steel clamp(s) give added protection to guarantee the pipe seal(s).
Provide premanufactured Alumi-Flash flashing systems as manufactured by Roof Products & Systems at all necessary roof penetrations 12" or less, or as shown on drawings. Each Alumi-Flash flashing system shall include a seamless .060" thick spun aluminum base with double-beaded collar which forms a WeatherTite Pressure Seal with the flexible rubber cap and molded EPDM rubber cap with stainless steel clamp(s). EPDM rubber shall have a serviceable temperature range of -60°F to +270°F and be resistant to ozone and ultraviolet rays. Use N18 Cap for up to four- 3/8" to 1" pipes, N21 Cap for up to four- 1" to 2" pipes, N28 Cap for up two- 3/8" to 1" pipes and up to two- 1" to 2" pipes, N62 Cap for single pipe from 2" to 6", and N182 Cap for single pipe 8" to 12" pipe. For all pipes larger than 13" diameter, use RPS Special Pipe Portal® Flashing System.
