About Us

The Sealmax brand started in 2000; however, we have been manufacturing weatherseal and weatherstripping since 1931. Originally doing business as Schlegel Canada Inc., Sealmax has undergone many changes since then, but one thing remains the same — quality products for your customer's home and family.

Sealmax is a wholly-owned subsidiary of Henniges Automotive, a global leader in automotive sealing systems.
