Heritage Character, Modern Performance

A flush casement window sits perfectly flush with the outer frame when closed — replicating the traditional appearance of original timber casements while delivering the energy efficiency, security and low maintenance of modern uPVC. A firm favourite for period properties, rural homes and conservation area installations across Newmarket and Suffolk. Compare with our vertical sliding sash windows for another heritage-style option, or explore standard casement windows for a contemporary look.

Flush Casement Windows in Newmarket & Suffolk

Period Character, Modern Performance — Installed by Micron Windows

Flush casement windows are the preferred choice for period properties, rural homes and conservation area installations across Newmarket and Suffolk. Unlike a standard casement, the sash of a flush casement sits perfectly flush with the outer frame when closed — faithfully replicating the appearance of traditional painted timber windows while delivering all the energy efficiency and low maintenance of modern uPVC.

At Micron Windows, we supply and install premium flush casement windows across Newmarket, Suffolk and Cambridgeshire. All installations are FENSA certified and compliant with UK building regulations. Request your free quote today.

Flush Casements vs Standard Casements

The key difference is the profile. A standard casement window protrudes slightly from the outer frame — a characteristic of modern uPVC manufacture. A flush casement sits completely flat in the frame, just as a traditional timber window would. This subtle but important difference makes the flush casement the natural choice for:

  • Period and listed properties where a traditional aesthetic is essential
  • Conservation area installations where guidelines specify a traditional appearance
  • Rural properties, farmhouses and country homes where timber aesthetics are important
  • Any homeowner who values a refined, considered appearance for their windows

Authentic Timber Appearance Without the Maintenance

Our flush casement windows are available in a wide range of authentic woodgrain finishes — light oak, rosewood, golden oak, grey woodgrain and more — as well as the full range of solid colours. The result is a window that looks like painted or stained timber but requires only an occasional wipe to keep it looking perfect.

uPVC will not warp, rot, crack or require painting. Your old frames are responsibly recycled via the UK’s leading uPVC recycler when we install your new windows. Read about our sustainability commitments.

We offer a colour-match guarantee across our flush casement windows, uPVC front doors, back doors and roofline range — so every element of your home’s exterior works in harmony. Visit our Newmarket showroom to see colour samples in person, or request a free home survey today.
