Our aluminium heritage single doors combine elegant, ultra-slim sightlines with classic period charm, designed to suit both contemporary and traditional settings. Styled to replicate the timeless appeal of early 20th-century steel doors, these doors provide an authentic heritage look using high-performance thermally broken aluminium. With an exterior that features Sheerline’s signature ‘stepped’ design, these doors capture the look of traditional steel while delivering modern benefits.

Sheerline's slim aluminium frames are designed to maximise natural light with sightlines as narrow as 60.5mm, making them ideal for creating an airy, light-filled space. These doors are not only low maintenance and lightweight but also feature robust rubber seals, allowing only sunlight to pass through and protecting against external noise and weather. Inside, each door is built with advanced Thermlock multi-chamber technology, providing superior insulation against the UK’s variable weather. These insulating chambers work alongside high-performance glazing to achieve thermal efficiency far exceeding that of conventional polyamide thermal breaks, keeping your home warmer and helping to minimise heat loss.

Whether you're looking to bring more light into an extension or need a door that complements a period renovation project, our aluminium heritage doors offers both aesthetics and practicality, all at a fraction of the cost of steel.

Manufactured and assembled in the UK, we guarantee top quality, compliance and security. Our in-house production and skilled staff ensure every door is perfect, allowing us to deliver quality products quickly and competitively.
