ASHZIP creates standing seam roof for Wanstead high school


A new 28-metre radius curved standing seam roof has been created on Wanstead High School's new Sixth Form block using 300m² of 0.9mm Ashzip from Ash & Lacy Building Systems.

Selected and installed by Logic Roofing & Cladding the roof construction also incorporates Ash & Lacy's Ashgrid spacer support system, which forms an integral part of the company's standing seam roofing package.

Providing an ideal contrast to the timber shiplap wall cladding the plain mill aluminium finish was factory manufactured in pre-curved 12 metre length sheets and the end laps welded on site.

To create the standing seam roof construction top hats were fixed to the timber roof trusses followed by a 0.7mm liner sheet. The Ashgrid spacer support system and Ashzip halters were then installed together with mineral fibre insulation and finally the Ashzip top sheet to create a non-combustible roof construction.
