What Dörken Systems does
Dörken Systems Inc. is the North American operating subsidiary of Ewald Dörken AG, a German family-owned industrial group founded in 1892. The company manufactures and distributes the DELTA® brand of high-performance air and moisture barrier systems for residential and commercial construction, with its North American headquarters and production facility located in Beamsville, Ontario (in operation since 1995, expanded in 2006 and again in 2022 with an additional 50,000 sq ft of production and warehouse space).
The product portfolio spans three architectural surfaces: roof underlayments (e.g., DELTA-TRELA for metal roofs), wall systems (DELTA-VENT SA/S air and water-resistive barriers, DELTA-FASSADE S/SA UV-stable barriers for open-joint cladding, DELTA-DRY ventilated rainscreens), and foundation/basement applications (DELTA-MS dimpled membrane, DELTA-DRAIN drainboards, DELTA-FL, DELTA-FOOTING BARRIER, DELTA-MS UNDERSLAB). Commercial extensions include garden roof drainage (DELTA-FLORAXX), heavy-duty horizontal/vertical drainage (DELTA-DRAIN 9000 HI-X, DELTA-MS 20, DELTA-TERRAXX), sub-base course, and tunnel membranes. Underlying technology rests on proprietary Air-gap Technology using vacuum-formed dimpled HDPE membranes (60% recycled / 40% virgin HDPE), high-performance spunbond substrates produced in-house since 2014, and self-adhering edge-lap systems with class-leading permeability (50 perms) and UV exposure tolerance (up to one year for DELTA-VENT SA). Products are qualified to ISO 9001:2015, ABAA/ASTM E2357, CAN/ULC S-742 Level 3, and ICC-AC38.
The business model is sales-led through a regional dealer portal and distribution network, supplemented by direct technical sales support to architects, builders, contractors, and engineers. Revenue is generated via hardware sales of membranes, drainboards, and a complementary accessories line (tapes, sealants, flashing, primers, fasteners). Customer segments are split across Residential Construction and Commercial Construction verticals, with named projects spanning healthcare, education, hospitality, government, multi-family residential, and automotive retail end-uses. North American leadership was refreshed in 2023 with Marcus Jablonka as President & CEO and Brandon Knobloch as VP of Sales & Marketing.
