Innovations reduce air leakage for energy efficient rolling steel door

Print

Until recently, air leakage was not a consideration in the rolling steel door industry. It was thought to be an impossible task—how do you stop air from coming through a door that is slatted? However, as codes became more stringent regarding reductions in air leakage, it started limiting the ability for architects to specify the best closure product for their application.

When to use TPO and when to coat?

Falls-River-Courthouse-TPOd

Building owners, commercial roof specifiers, architects, and contractors have some decisions to make when it comes to the material they should use to repair or replace a low-slope roof. Three popular choices include: coating over the existing roof; thermoplastic polyolefin (TPO) recover (putting a layer of TPO over the existing membrane); or TPO replacement (tearing off the existing membrane and installing a new TPO membrane).

Specifying architectural zinc

Zinc-Roof-Castle-Miramare

Architectural zinc (titanium-zinc alloy, rolled zinc, zinc strip) is a soft, natural-weathering metal that has been used for centuries in various roof applications. Its value reaches far beyond beauty and durability. Following ‘zinc-appropriate’ design, a quality metal roof specification will not follow a standard painted metal specification, but instead cover issues unique to this material. In some cases, prescriptive requirements for the material quality, technical support, panel profile, installer qualifications, and detail quality will be necessary.
