What Are Internal Heritage Doors (AluSpace)? 

AluSpace internal aluminium doors, partitions and room dividers replicate the look of traditional steel doors indoors, using slim aluminium frames. With sightlines down to 33mm, they’re built to maximise natural light while creating sharp, architectural divisions between rooms, whether that’s a hinged single door, French doors, a sliding door, a fixed screen or a full partition wall.

Every one is a genuine steel look internal door, built in aluminium for a fraction of the price and upkeep of the real thing.

Key Features 

Ultra-slim 33mm sightlines

Single-pane glass or acoustic double glazing options

No door threshold, so the floor finish runs through for a level, step-free transition between rooms

Fully bespoke, made to measure

Over 200 RAL colours and a range of textured finishes, including colour-matched hinges

25-year paint finish guarantee

AluSpace Internal Doors & Screens: Smart Configurations 

Sliding or Regular Openings – sliding doors for space-limited or open-plan areas; hinged single or double doors for a more classic, heritage-inspired statement entrance.

No Threshold – the floor finish runs straight through from room to room, with no step and nothing to trip on, for a seamless and accessible transition between living spaces.

Glazing Options – single glazing for a clean, minimal look; double glazing for improved thermal performance; acoustic glass to reduce sound transfer between busy rooms or home-working spaces.

Top Lights – a glazed top light or top panel to bring light into hallways, landings or rooms with limited windows, without losing the separation between spaces.

Handles and Locking Options – sleek black painted hardware for a contemporary, industrial look, or brass and metallic finishes for a warmer, more classic feel.

Made in the UK

As a family-run business, the quality of our products matters to us. All of our AluSpace doors and partitions are handmade at our factory in Keighley, West Yorkshire, drawing on our background in aerospace engineering to inform rigorous quality control and testament to the reviews below. We have been manufacturing heritage aluminium doors and partitions continuously since 2003. If you’d like to see for yourself, you can arrange a visit to our showroom to look at the doors and partitions, and see the manufacturing process in person.

”We used Marlin for windows and traditional Steel Replacement doors and screens on our recent self build project. Marlin are not local to us but provided an excellent service from quotation, advice, redesigns and with very detailed comms throughout. The windows and doors are the talking point of our entire build. Adrian from Marlin said that windows become the eyes of the house and I didn’t forget that – our eyes are simply stunning.” Would highly recommend.
