What is a flush sash window?

Intricately made to seamlessly replicate the look of authentic timber, flush sash windows fit sleekly into the window frame, instead of slightly overlapping the window frame, for a smooth finish. Created from the highest quality and low maintenance uPVC, our flush sash windows deliver unmatched thermal insulation and weather protection, alongside intricate handcrafted details unseen on a timber alternative window - until now.

Why choose a flush sash window?

Cost-effective, authentic timber sightlines

Much cheaper to construct than timber, our uPVC flush sashes can be customised in three realistic jointing options; fully welded, full mechanical, or mechanical/weld.

Advanced thermal insulation

Available with 3, 5 and 6 insulating chambers, our multi-chambered uPVC flush sash windows attain A energy ratings with ease.

Superior security

Complete with secure multi-point locking and able to last up to 35 years, our flush sashes are PAS 24 security accredited as standard.

Low maintenance

Our uPVC flush sash windows offer a maintenance-free design that won't rot, crack, warp, or fade throughout its lifespan (unlike real timber).

Sustainably sourced

As well as offering EcoMax Glass as standard, our flush sash windows are created from 80% recycled manufacturing off cuts.

Peace of mind

Backed by a 10-year guarantee and a commitment to exceptional craftsmanship and customer satisfaction.

Can I put uPVC windows in a listed building?

If you live in a listed building or a home located in a conservation area, extra care must be taken to retain the original look of the property. Unauthorised improvement work in designated areas can result in an unlimited fine, so if you're unsure whether your home is in a conservation area, get in touch with your Local Authority for clarity before going ahead with any work.

High-quality timber replica windows (like ours!) are designed to pass strict regulations often imposed on listed buildings, conservation areas, Areas of Natural Beauty (AONBs), and other areas limited by protective Article 4 Directions. So, you have absolute peace of mind your home complies with the rest of the neighbourhood, whilst looking its very best at all times.
