Coventry window manufacturer snapped up by Swedish giant Assa Abloy


Sweden-based access solutions company (doors, windows, turnstiles, hotel security, turnstiles and that sort of thing), Assa Abloy has bought Coventry-based specialist window hardware manufacturer Caldwell.

Nico Delvaux, President and CEO of Assa Abloy, said:

“I am very pleased to welcome Caldwell into the Assa Abloy Group. This acquisition delivers on our strategy to add complementary products and solutions to our core business.

“Caldwell is an excellent addition to the Pacific & North East Asia Division and provides complementary growth opportunities. The acquisition will strengthen our position with fenestration manufacturers and I look forward to working with the experienced team to continue Caldwell’s successful journey,” added Simon Ellis, Executive Vice President and Head of Asia Pacific Assa Abloy Opening Solutions Pacific and North East Asia.

Founded in 1888 by Allen Boucher and William Caldwell, Caldwell Hardware supplied clock spring counterbalances for window construction throughout Northeast America.

In 1948 it developed the first spiral balance – Spirex – catapulting Caldwell to the top of the window hardware market.

The 1950s saw the introduction of breakthrough new products, weatherstrip balances Spiraflex and Rib-Tite.

During the late 70s Caldwell developed Trim-Tilt for wood and Aluma-Tilt for aluminium to allow hung windows to tilt to the inside for safe and easy cleaning.

In 1991 it launched Ultra-lift balances, its first hybrid balance designed to balance large and heavy windows.

In 1973 Caldwell embarked on a joint venture with an English window manufacturer to supply products to the UK and European markets. Caldwell eventually bought out the partners and established Caldwell Hardware United Kingdom.

2014 saw the acquisition of leading international friction hinge manufacturer Cotswold Architectural Products. This was a strategic move for both Caldwell and Cotswold by bringing together two of the most respected names in the window and door hardware markets.

The company employs around 800 members of staff.
