Prestige Doors

Prestige combines aluminium’s clean lines with exceptional thermal performance for up to an A+ Window Energy Rating.* Our innovative Thermlock® multi-chamber thermal design, hidden away inside each window and door, helps keep you and your property well insulated against the worst of the UK weather. This closed-cell, insulating chamber acts as a thermal break and works in conjunction with high performance glazing to create class leading thermal performance, far superior to traditional polyamide thermal breaks. Sheerline’s cills also feature this same technology coupled with innovative in-built weather sealing keeping draughts and rain safely outside.

Prestige features a choice of three low thresholds that have been tested to the requirements of Part M, alongside continuous frame options. These allow easier access, while reducing trip hazards. Door frames fix to these thresholds using a universal moulding that’s hidden from view from the outside. A cover strip continues the high end aesthetics, hiding the fixings, but can be slid under the moulding to aid removal if required.

With sightlines starting as slim as 88mm, Prestige windows and doors help maximise the daylight entering your home, with crisp aluminium detailing creating a refined and architectural look. While our patented construction method – using threaded screws to bind corners tightly together – helps eliminate misaligned corner issues that can occur on ordinary aluminium frames. This allows each Sheerline window to be individually hand tuned to perfection. Leaving you with the perfect balance of understated refinement coupled to exacting quality standards, where no detail’s overlooked. Creating consistent aesthetics across every Sheerline window and door.

Sheerline aluminium doors are available in a choice of two opening sash styles; ‘Stepped’ – inspired by traditional steel windows – and ‘Contemporary’ with a more modern minimalist aesthetic. We are happy to offer advice about which will complement your home’s style perfectly if required.
