Perpendicular roof expansion joint.
Expansion joint systems nystrom s expansion joints are manufactured to solve a variety of expansion joint scenarios.
Standing seam roofs are more flexible in the direction perpendicular to the ribs as compared to the direction of the ribs.
In general the top surface of the curbs should be sloped away from the joint to shed condensation and moisture onto the roof.
Watertightness is achieved through positive integration with the roofing membrane and a purpose designed system for transitioning between the joint in the roof and joints in walls.
Custom sizing materials and color finishes ensure that whatever you need for your project we ve got you covered.
They are designed to accommodate the free movement of building elements without damage to the roofing system.
Perpendicular and parallel to the joint in the horizontal roof plane and perpendicular to the roof in the vertical plane.
A roof expansion joint emseal roofjoint is a patented dual seal double flanged extruded thermoplastic rubber system for sealing expansion joints in roofs.
Thus expansion joints can be spaced at greater distances than those perpendicu lar to the ribs.
Expansion joints in roofs require wood curbs around each roof area.
Each expand o flash cover is a combination of a flexible rubber membrane supported by a closed cell foam to form flexible bellows with two metal flanges adhesively and mechanically combined to the bellows by a patented bifurcation process.
This is better than putting horizontal colorseal in a curb and terminating the roof membrane on the curb because that approach lacks a positive roof membrane integration.
Get moisture protection from the top down with roof covers from construction specialties.
Our exterior joint systems provide superior aesthetics by hiding joint seams to maintain that crisp look.
Expand o flash expansion joint covers are flexible weather proof exterior covers for expansion joint openings and are an effective flexible closure for a wide variety of standard and special applications.
Because like with our fp systems for plaza decks the roofjoint flanges ensure a static positive integration of the expansion joint to the roof membrane.
Our roof covers have extensive model options for flat and built up roofs.

When properly designed and applied expansion joints will allow for movement in three destinations.
