01Timber windows
What is a timber casement window?
A timber casement window is a side-hinged window that opens outward, as on British cottages and period terraces. Each is made to order for its opening, in a flush or stormproof profile.
Stormproof casement
A lipped sash overlaps the frame and compresses the seals harder, for elevations that take wind-driven rain head on.
Timber chosen per elevation
One house can need two timbers: harder or modified on exposed walls, lighter on the sheltered side, advised at survey.

04Asked before every survey
The questions that matter.
How often does a timber window really need repainting?
Every 8 to 10 years for opaque paint, 5 to 7 for a stain. Between coats, wash the frames twice a year and apply a restoring balm once a year. Skip that on a south-facing wall and the finish can chalk within 3 years.
Won't the timber swell and stick in winter?
Not when the timber and fit are right. Engineered timber, glued from alternating-grain layers, moves 2 to 3 percent against 7.5 for solid pine. The frame needs a 5 to 10 mm expansion gap all round, sealed with expanding tape and flexible sealant, not foam.
Which timber should I choose?
Choose by how exposed the wall is. Pine suits sheltered walls and needs the most disciplined upkeep. Meranti and oak take more weather, and oak is the species conservation officers most often accept. Accoya, a modified timber, neither swells nor shrinks.
Will timber casements be approved in a conservation area?
Timber is the safest route, but the council decides. Where an Article 4 direction applies, replacement usually needs consent and like-for-like detail: timber, a flush profile, slim glazing bars. Check with your planning department first; we supply to the specification it sets.
