Flush Casement Windows

Flush casement windows are the authentic choice for period, character, and premium modern homes. Unlike standard casement windows where the sash sits proud of the frame, flush casement sashes close perfectly flush into the outer frame – recreating the elegant, flat exterior appearance of traditional timber or critically-listed steel windows from the 19th and early 20th centuries.

Why Homeowners & Conservation Officers Love Flush Casement Windows

1. Genuine Heritage Appearance -The clean, flat outer face with no overlapping sash perfectly replicates pre-1930s timber and Crittall-style metal windows – essential for listed buildings, conservation areas, and Article 4 properties.
2. Beautifully Slim Sightlines -Especially in aluminium or Accoya timber versions, sightlines can be as narrow as 35–45 mm, giving a refined, elegant look that storm-proof casements simply cannot match.
3. True Multi-Point Opening -Sashes open fully outward on high-quality friction hinges with night-vent options and easy-clean fire escape hinges where required.
4. Outstanding Modern Performance
   • A-rated energy efficiency (U-values as low as 1.2 W/m²K with triple glazing)
   • Advanced weather seals and draught-proofing far superior to old timber
   • Double or triple glazing with warm-edge spacers and argon fill
   • Acoustic laminates available for noisy locations

1. Material Options to Suit Every Project
   • Timber – Engineered softwood or Accoya for 50+ year lifespan

   • Residence 9 / Heritage 3000 – Premium uPVC systems designed specifically for conservation areas

1. Traditional & Contemporary Detailing
