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 properties 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 a choice of three low threshold options 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.

Our patented construction method – using threaded screws to bind corners tightly together – helps eliminate misaligned corner issues that can occur on ordinary aluminium frames. Allowing each Sheerline window to be individually hand tuned to perfection. This innovative corner jointing method also does away with the need for crimping and specialised machinery and drastically reduces waste. Larger frames can also be assembled in situ if required.

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. As all our systems share common components and are designed with consistent aesthetics and features, ou can confidently specify from across our range of products.Confident that aesthetics, colours, styles and sightlines will match perfectly across a project.

Sheerline’s cills, ancillaries and corner posts, also feature Thermlock® technology coupled with innovative in-built weather sealing that keep draughts and rain safely outside, help eliminate any condensation issues caused by cold bridging, and reduce the need for onsite sealing. All based on a common chassis helping to reduce product complexity. This innovative clip together approach also means dual colours are easy to assemble and stock utilisation is improved.
