The R9 profile has been carefully developed to mirror classic timber window proportions, with a deep, flush sash design suited to heritage and conservation requirements.

The unique 100mm frame depth and nine internal chambers provide outstanding thermal performance and strength, while accommodating traditional detailing.

Manufactured as fully mechanical and glass bonded for authenticity, the ‘easy clearn rebates’ are also foiled in the same finish, so the high end appearance carries through even when the window is open.

R9 supports both 28mm double and 44mm triple glazing. All frames are built using traditional mechanical joints, replicating authentic timber joinery.

Choose from The Residence Collection’s curated palette of heritage tones, period woodgrains, and dual-colour options for bespoke finishes inside and out.
