Sheet metal roof expansion joints.

Flat seam roofs used in low no slope areas or areas subject to flooding or standing water typically made from 20 x 28 sheets relative geometry is important fro expansion and contraction sheet use efficiency and wind load. We constantly innovate and incorporate the latest technology to protect commercial buildings from damage due to fires and movement from thermal expansion wind or earthquakes. Exterior cap is available in 24 prefinished kynar 500 colors. Copper or stainless steel is recommended lock and seal all joints solder joints on slopes less than 3 12.

Perma tite expansion joints are ideal for allowing thermal movement and condensation control between two roof systems. This carefully engineered product ensures long lasting quality and high performance. Standard sizes to fit expansion joint opening of 2 3 or 4. Sheet metal components enable low cost design variations in size to fit job conditions.

The architect resources page aims to help architects and specifiers make informed decisions about what roofing system is best for their specs. Factory fabricated intersections are designed for maximum flexibility and are produced using special fabrication techniques to ensure watertight clean seam lines.
