K-Flex™ AL CLAD

Designed for the professional contractor

Elastomeric Insulation Clad with Aluminum Foil/Laminated to Polypropylene Sheet


K-Flex™ AL Clad, available in both tubular and sheet form is a composite product comprised of flexible closed cell elastomeric insulation adhered to an outer covering comprised of an abuse resistant, easy to clean, aesthetic polypropylene sheet laminated to an aluminum foil, providing weather resistance, UV protection and mechanical abuse protection. It is an ideal choice for outdoor applications (roof top), food processing plants, pharmaceutical, film processing, electronics and other clean room applications.

The polypropylene / aluminum cladding provides a secondary moisture vapor barrier inherent to the closed cell foam core.

The primary function of the cladding is weather resistance, clean ability and protection from UV rays. The smooth shiny surface is tough, impact resistant and dust free, resistant to acids, alkali, salts, oil, fats, aliphatic hydrocarbons and is highly impermeable to gases and moisture. The flexible cladding provides resistance to traffic (does not dent like traditional metal jackets) as well as excellent appearance and easy maintenance. The K-Flexâ„¢ Al Clad System allows for quick and easy replacement should this be required.

The unique closure system (over lap system for longitudinal seams and butt joints) – no through seams – insures against moisture penetration. No special tools and fewer materials necessary at the job site make proper installation a snap. K-Flexâ„¢ Al Clad is light and easy to handle. The K-Flexâ„¢ Al Clad system provides installed cost savings over traditional metal jacket systems with improved performance in many cases.

This composite product has a low thermal conductivity and a high water vapor diffusion resistance factor. It practically eliminates the problem of under insulation corrosion. It is easy to install and combines long term performance with low maintenance requirements. The preformed elbows, tees and matching tape make install quick, professional, with excellent appearance and durability.

Standard K-Flex™ AL CLAD can be used within a wide range of temperatures from -297°F to +220°F K-Flex™ ECO should be requested as the foam core on stainless steel applications above 100°F. The temperature range is for K-Flex™ ECO is from -297°F to +300°F.

K-Flex™ AL CLAD is a fiber free, non-porous insulation product. K-Flex™ Al Clad is CFC and HCFC free, with an Ozone Depletion Potential of Zero. These characteristics make it easy to comply with Health, Safety and Environmental requirements.

Tubular product is available in all standard ID’s 1/2" 1" and 1-1/2” wall thicknesses in nominal 3 foot lengths. Sheet product is available in 36”x48” dimensions or 48” wide rolls. The sheets and rolls are available with an aggressive acrylic pressure sensitive adhesive (PSA) with fiber glass scrim reinforcement and a moisture/tear resistant polyolefin easy release liner.
