About Us

From early origins as glass merchants and processors, the Holdens name has been synonymous with quality within the glazing industry for  over 80 years.

Increased demand for construction materials after the war helped sustain growth throughout the 1940s , 50s and 60s.

In the 1970s Holdens set up Holdens Supaseal ltd to manufacture and supply double glazed units. Holdens this year is now celebrating its 40th anniversary as Supaseal.

Holdens SupaSeal ltd is still operated by a fourth generation of the original family, the company has maintained a prominent position in the glazed unit market through customer-led product development, quality standards and high levels of customer service.

New products continue to be added to the portfolio including high energy efficient glass range,  Supaslim heritage units and SupaShade integral blinds.
