Cladding Designed for Cold-Weather Installation

Thursday, August 5, 2010

Polyguard Products Inc. has introduced the hybrid Alumaguard LT cladding system for outdoor installations on duct and piping systems.
  
Alumaguard LT combines the attributes of a self-healing membrane with the all-weather installation of acrylic adhesives, the company says. The product can be used on the entire duct, including the bottom.

Developed in response to requests for a product suitable for cold-weather installation, Alumaguard LT is suitable for chilled water piping, process piping, exterior duct work, or almost any system that requires protection from water intrusion, the manufacturer says.

Alumaguard is available in smooth and stucco-embossed natural aluminum. Standard sizes are 3 or 36 inches wide by 75 feet long; a 23-inch width is available as a special order.

Also new is the company’s Alumaguard Lite cladding product. Alumaguard Lite is 25/50 rated, zero perm, with a low-temperature acrylic adhesive fastening system. Originally designed for the bottom of ductwork to alleviate sagging of the heavier rubberized asphalt-based product, Alumaguard Lite can be used on the entire duct or piping system, the company says.

Alumaguard Lite is appropriate for chilled water piping, exterior duct work, interior duct work, mechanical rooms, indoor piping systems, process piping, and plenum areas, according to the manufacturer.

It is available in smooth aluminum, stucco-embossed aluminum, and smooth SuperWhite (aluminum inside). It is available with adhesive in standard 3- and 36-inch widths and 150-foot lengths (a 23-inch width is a special order). It is also available to fabricators in 23- and 36-inch widths by 500- and 1000-foot lengths without adhesive for factory-applied uses.

Alumaguard is a vapor barrier, weather barrier, and UV barrier in a “peel n stick” roll membrane. It is rubberized bitumen, a foil-faced membrane designed to stick to insulation facings such as FSK, smooth foil and ASJ. According to the company, Alumaguard has an excellent perm rating, puncture resistance, and sound attenuation properties (STC 18). As with all of its membranes, the company says, Alumaguard heals itself if punctured.
