EXPANSION & WALL CURB SYSTEM TO BE USED WITH ALL DECKS AND CONVENTIONAL ROOF SYSTEMS

RPS Expansion & Wall Curbing allows for uniformity in method and design while also providing excellent flashing and termination points with a watertight installation. This RPS system includes expansion joint curb in desired lengths, fully mitred one piece inside and outside corners, sloping end sections, spreader and connector clips. By utilizing this system you can begin roofing as soon as the deck is in place. There is no need to wait for the mason or siding contractor to erect walls to connect the roofing system. This system installs at a fraction of the time required over costly field built arrangements. It is also designed to meet any roofing system while allowing single source responsibility.

EXCERPT FROM N.R.C.A. MANUAL
ARE ROOF EXPANSION JOINTS NECESSARY?

The necessity for expansion joints, of course, depends upon the design and size of the building. We would like to point out, however, that hundreds of buildings are being constructed, from plans out of good architects' offices, without any or without enough roof expansion joints. On any rather long building, having wings extending from the main portion of the building, a roof expansion joint should be provided at each junction of the main portion of the building, with a wing. On buildings 150 feet or more long, a roof expansion joint should be provided at each change in the deck direction. Every building having a length of more than 200 feet should have a roof expansion joint. See that curb type expansion joints are used and/or detailed. Never use the metal “U” type expansion joint on a roof.
