  • FrameGuard
    R-Control SIPs are heavyweights against the destructive
    agents of mold, mildew, and termites. The Foam-Control ®
    EPS in R-Control SIPs is treated with Perform Guard termite®
    protection. And the entire SIP, when treated with the
    FrameGuard Coating.

  • Safe and Effective.

    R-Control SIPs FrameGuard Coated are protected with
    organic fungicides and a borate compound tested to be
    effective.  The organic compounds remain close to the sur-
    face to provide protection against mold; moldicides inhibit
    the enzymes’ ability to break down the wood and consume
    the sugars and starches mold needs for growth.  Meanwhile
    the borate component penetrates into wood providing pro-
    tection against both fungi and termites.
