Something familiar…reinvented. Simple, thermally isolated Z-furring: exceeds code
KWS® THERMAZEE® gives installers and designers the simplicity of what they know: Z-furring; with what they need: code compliant thermal performance. With reduced thermal bridging that rivals modern thermally isolated clip and rail systems, the thermally improved THERMAZEE® dramatically increases the rainscreen wall assembly’s performance.
Being primarily comprised of steel, THERMAZEE® offers a resilient, durable and non-combustible option to meet today’s high demand.
THERMAZEE® employs a specially designed, hollow, thermal isolation strip complimenting other performance enhancements at the web of the girt. The webs unique punch pattern has a substantial reduction in metal penetrating the insulation – about 75% – which decreases heat-flow through the girt. Additionally, the girt’s notched bends and flared punches add extra strength.
Like traditional Z-furring, THERMAZEE® can be installed either vertically or horizontally, attached to a variety of substrates such as steel studs, wood studs, CMU and concrete. Also, like traditional furring, a variety of claddings can be attached directly or with secondary rails. These include fiber cement, metal panels, HPL panels or aluminum composite material (ACM), among others.
THERMAZEE® can be specified and purchased as a standalone girt, with or without thermally isolated wall anchors by KWS®. Additionally, KWS® can provide project-specific engineering if requested.
Advantages to the KWS® THERMAZEE®
- Typical installation – installs just like traditional Z-furring
- Highly perforated for increased drainage
- Primary load supporting element is non-combustible – similar to a shimmed rail or girt – but with superior thermal and structural properties.
- Wall anchors can be supplied by KWS® or others*
- THERMAZEE® can be spaced up to 48” O.C. when used horizontally, or up to a 32” O.C. (every other stud) when used vertically*
- No trimming of mineral wool insulation required for a snug fit
- Pre-punched wall anchor holes for easy installation – especially over wood and CMU/concrete substrates
- Highly corrosive-resistant Zn-Al-Mg ZM40 (ASTM A1046) coated steel for long service life vs. typical G90 galvanized steel
- Black PVDF finish and stainless-steel options are available
- Delivered with preassembled thermal isolation strip – ready to install
- Easily installed over many substrates – steel studs, wood studs, CMU, concrete
- Engineering calculations can be provided per project for design load compliance (optional)
- Can be supplied as a full attachment solution – thermally isolated furring, fasteners, secondary rails and engineering (optional)
- Limited extended labor and material warranty available (optional)
