The tape measures 1 inch wide by 1 inch thick and comes in a 13-foot roll. It expands after installation to conform tightly to irregular gap surfaces, creating a watertight seal. The formulation is non-staining and UV-stable, making it suitable for both interior and exterior applications. Installers in HVAC, plumbing, and general building trades use this tape wherever a compressible, self-sealing foam barrier is needed.\u003c\/p\u003e\n\u003cp\u003eThis foam tape is suited for residential and light commercial applications including door and window frame sealing, pipe and duct penetration sealing, and weatherproofing around rough openings. The self-stick backing allows single-person installation without additional adhesives or fasteners. Its ability to conform to uneven surfaces makes it useful wherever gaps vary in width or depth along the run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExpandable foam construction conforms to irregular and uneven gaps\u003c\/li\u003e\n  \u003cli\u003eSelf-stick backing — no separate adhesive required\u003c\/li\u003e\n  \u003cli\u003eWatertight seal for exterior and moisture-prone locations\u003c\/li\u003e\n  \u003cli\u003eUV-stable formulation resists degradation from sunlight exposure\u003c\/li\u003e\n  \u003cli\u003eNon-staining — safe for use against finished surfaces and trim\u003c\/li\u003e\n  \u003cli\u003e13-foot roll covers typical door or window perimeter in a single length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose weatherseal solution for gaps in residential and light commercial construction, including door frames, window frames, and mechanical penetrations where a compressible foam seal is appropriate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eClean and dry the mounting surface thoroughly before applying the self-stick backing to ensure full adhesion.
