Polyguard Waterproofing Products
Polyguard Summary
In the late 1960′s Polyguard’s major business was self-adhesive tapes, used as Corrosion Coatings on underground steel pipelines. The idea of modifying these self-adhesive coatings into Vapor Barrier Walls and building envelope solutions that include Underslab Vapor Barriers as well as solutions for Blindside Waterproofing to protect structures from water and moisture advanced and the Architectural Division was born.
Polyguard began with Polyguard 650 membrane waterproofing, a product which by the mid 1990′s was specified worldwide for foundations and plaza deck protection.
In the 1980′s Polyguard moved above grade, protecting the building envelope with Roofing Underlayment products, Window Flashing, Thru Wall Flashing, walls, decks, and tile underlayments.
In 2003 Polyguard introduced the Underseal™ line, a Below Grade, Blindside Waterproofing and Underslab Waterproofing product line with more moisture barrier features than any product on the market today. More importantly, the Underseal™ line contains technology, proven over 30 years by state DOT usage and research, which reduces the amount of cracking in slabs and maintains a permanent seal when the slab does crack.
Polyguard also offers solutions for Air Barrier Walls, Drainage Board and Drainage Panel Systems, as well as Methane Barrier and Radon Barrier systems

Architectural Accent is also the Southern California Regional Sales Representatives for Carlisle Residential Products

Carlisle Construction Materials (CCM) formed the Carlisle Residential Products Group in January 2008. This new division adds focus and unity to Carlisle’s existing residential operations and solidifies Carlisle’s position as a leader within the entire building construction community. The following product lines now fall under the Carlisle Residential umbrella: Water and Ice Protection (WIP®) underlayments, EZ-Flash and ENsulation.
WIP 300HT, manufactured by Carlisle Residential Products, was recently recognized as a Top 10 Product by Metal Roofing magazine. Selection into the Top 10 was based on the total number of reader requests for more information on specific products featured in the publication. WIP 300HT drew a high level of interest from readers when it was featured in the magazine’s underlayment product profile in the August/September issue.
WIP 300HT is a self-adhering, rubberized asphalt underlayment specifically designed to endure temperatures up to 240°F. It is perfectly suited for use under metal roof systems, as it resists intense heat without degradation of the adhesive.
