Flush Sash Windows

Added Elegance

Heritage look, modern performance

Flush sash replicates traditional timber casements with authentic, slim sightlines and a neat, understated profile. From period cottages to minimalist extensions, the design blends in effortlessly while elevating kerb appeal. Choose from a wide palette of colours, including classic whites, soft neutrals, and popular greys, plus ultra-realistic woodgrain foils that mirror the texture of painted or stained timber—without the upkeep.

Add dummy peg stays, mechanical joints, and traditional hardware for a convincingly period aesthetic, or specify sleek contemporary handles for a modern twist. Bring your plans to the showroom and we’ll help you finalise the perfect combination.

Warm, efficient, and quiet

Behind the heritage styling is a multi-chambered uPVC frame engineered for thermal efficiency. Specify high-performance double or triple glazing to retain heat, cut draughts, and improve acoustic comfort—great for homes near busy roads or schools.

The flush exterior and quality seals help reduce air leakage, while low-iron, argon-filled glass options support excellent energy ratings. The result is a brighter, more comfortable living space with lower everyday maintenance than traditional timber and dependable performance all year round.

Secure and built to last

Every unit is designed around robust security and longevity. Multi-point locking engages the sash at several positions to resist forced entry, and reinforced frames add rigidity where it counts.

Weather-resistant gaskets, advanced drainage, and durable finishes mean no sanding, no repainting, and no warping—just an occasional wipe-down to keep them looking their best.

Choose toughened or laminated glazing for rooms that need extra security or safety.

Made for sensitive settings

Flush aesthetics make these windows a natural choice for character properties and conservation-style refurbishments. Many local authorities recognise the sympathetic appearance of flush casements; if you’re in a listed building or designated conservation area, our team can help with technical details (sightlines, section drawings, and sample swatches) to support your application. Speak with us early and we’ll advise the most appropriate specification for your project.
