Clement Brooking Range of Steel Windows

As experts in historical fenestration, we understand the importance of retaining the period features of a home. That’s why we’ve developed our Brooking range, which perfectly combines modern window technology with traditional aesthetics to keep homes looking and performing their best.

Developed in collaboration with The Hampstead Garden Suburb Trust and other conservation bodies, the Brooking range of steel windows takes its name from the Founder of The Brooking National Collection, Charles Brooking, an internationally renowned collector, conservationist and architectural historian with whom the Clement Windows Group has had a long association. The Brooking National Collection is a broad collection of period British windows, doors and other associated historic detailing.

Designed for buildings which require a specialist ‘putty fronted’ system, these windows are specifically for use in sensitive fenestration projects where a traditional appearance is required and can be specified as either single glazed or insulated glass units. This makes the range perfect for Listed Buildings where strict building regulations apply.

Dependent on the individual property and architectural requirements, windows from the Brooking range can be adapted using powder coating and weather stripping details.

Brooking steel windows are manufactured from recycled steel.


  • 16mm insulated glass units, silicone fronted
  • Single point locking
  • Various glazing options
  • Supplied with semi, round or gothic style heads, or ‘curved on plan’
  • Produced from 98% recycled steel source material
