DraftSeal

What DraftSeal does

DraftSeal (legal entity A.K. Draft Seal ULC, formerly A.K. Draft Seal Ltd.) manufactures door weather-stripping, thresholds, sill systems, and related weatherseal hardware for residential and commercial applications. Founded in 1960 by Anton Kamensek in Langley, British Columbia, the company has operated continuously for over 60 years and self-describes as the largest manufacturer of weather-strip products in Western Canada. Its product portfolio spans commercial thresholds (thermally broken, heavy-duty, ADA-compliant, fire-rated variants), commercial door weatherseals (automatic door bottoms, sweeps, shoes, gaskets, meeting stiles, astragals), commercial door louvers and lite kits, residential pre-hung door sill systems (including the 2013-launched DS1 Storm-Sill System with proprietary water-return architecture and TPV continuous cornering weather seal), residential seals and astragals, and specialty products such as backer rod and weatherseal tapes. The DS1 system is tested to AAMA/WDMA/CSA 101/I.S. 2A440-11 and is NAFS-11 / NASF compliant.

The company operates a B2B, channel-only go-to-market model. It does not sell directly to the public; instead it sells through building-supply retailers (Windsor Plywood, Dicks Lumber, Standard Lumber, Richmond Building Supplies, Slegg Building Materials) for the DIY/residential consumer segment and through lumber yards, building-supply distributors, and specialty door/hardware wholesalers (Access SMT, ALLMAR, CP Distributors, Country Lumber, North Shore Door) for commercial customers. Pricing is not publicly disclosed and is set through B2B distribution relationships. The company maintains three company-operated locations: a head office and manufacturing centre in Langley, BC, and branch distribution centres in Mississauga, Ontario and Commerce, California. A sister division, Kristrack Manufacturing Ltd. (founded 1991), produces interior track and hardware for sliding, bifold, and pocket doors and shares DraftSeal's distribution channels.

In early 2023, A.K. Draft Seal Ltd. and Kristrack Manufacturing were acquired by National Guard Products (NGP), a family-owned U.S. manufacturer of commercial door products founded in 1935. The Canadian entity was subsequently renamed A.K. Draft Seal ULC and operates as a wholly-owned subsidiary of NGP. Post-acquisition, DraftSeal's website promotes the complete NGP Anemostat line, signaling cross-sell of louvers and vision lites through DraftSeal's Western Canada distribution footprint. Customer segments are split between pre-hung door OEMs (primary, business-supply relationship) and residential consumers reached via building-supply retail (primary, DIY), with commercial door/HVAC contractors as a secondary segment.
