Internal Doors: A Practical Guide to Dividing Living Areas, Improving Comfort and Reducing Noise

Internal doors have become an increasingly popular way to create flexible living layouts, define different zones and add architectural character to modern homes. As open plan designs continue to grow in popularity, more homeowners now want the option to separate rooms when needed, without losing light or a sense of connection.

At Burgess Windows and Doors, we supply and install two of the leading aluminium internal door systems in the UK, Origin and Aluco. Both offer slim sightlines, steel look styling and fully bespoke configurations suited to a wide range of residential and commercial projects.

This guide explores the benefits of aluminium internal doors, including thermal comfort, acoustic improvements and how Origin and Aluco compare.

Why Internal Doors Are Becoming Essential in Modern Homes

Create defined living zones

Internal glazed doors make it easy to divide areas of the home while keeping light flowing from room to room. They work particularly well between kitchens and dining rooms, lounges and hallways, or as a way to create a quiet study or playroom. The slim aluminium frames help maintain an open feel even when the rooms are separated.

Improve thermal comfort

Dividing larger spaces can make it easier to retain warmth in colder months and maintain cooler areas during summer. Closing internal doors helps reduce movement of warm or cool air between rooms. Research from the Royal Institute of British Architects highlights how thoughtful interior zoning can improve daily comfort and the way a home functions.

Reduce noise between rooms

Aluminium internal doors with the right glazing options can help reduce sound transfer between busy areas of the home. This is especially useful for home offices, utility rooms, living spaces and bedrooms. Acoustic glass options are available across both Origin and Aluco systems.

Aluco Internal Doors and Screens

Aluco creates highly refined steel look internal systems that are designed around the glass for perfect symmetry from both sides of the door. With ultra slim frames and distinctive industrial styling, Aluco offers one of the closest matches to traditional steel.

Key design features of Aluco:

  • Slim 47mm sightlines
  • Ultra thin 20mm glazing bars
  • No visible threshold and 10mm floor clearance
  • Balanced centralised glazing
  • Wrap around sash for improved acoustics
  • Floating lock design for a fully glazed look
  • Single doors up to 1000mm by 2500mm
  • Double doors up to 1900mm by 2500mm
  • Black and grey as standard with special colours available

Aluco doors are handmade using high quality aluminium profiles, offering a combination of appearance, performance and precision. Matching screens can also be added to create wider dividers, corner screens or fixed feature panels. These are made to measure with options for clear, obscure or acoustic glass.

Origin OI 30 Internal French Doors

Origin’s OI 30 internal door system combines classic steel look styling with a wide range of configuration choices. Manufactured in the UK, Origin provides strong aluminium construction, dependable lead times and excellent flexibility for both homes and commercial environments.

Advantages of the Origin OI 30:

  • Door heights up to 2500mm and full system heights up to 3048mm
  • Door widths up to 1000mm
  • Available in more than 150 RAL colours
  • Durable powder coated finish
  • Customisable glazing bar patterns
  • Choice of glazing thicknesses
  • Multiple hardware and handle options
  • Latch only or locking choices

Origin’s modular approach makes it easy to design a layout that fits your home. You can select the glazing, frame style, bar configuration and handle details to create anything from a simple single door to a large French set with fixed side panels.

Which Internal Door System Is Right for You

Both Aluco and Origin offer premium steel look internal doors, but each system suits different project requirements.

Aluco is ideal where extremely slim sightlines, a more traditional steel appearance and unique design features are important. Origin is suited to projects where a broad colour range, larger sizing, UK manufacturing and faster lead times are preferred.

Our team can guide you through both options and help you choose the right system for your home or commercial property.

Final Thoughts

Internal aluminium doors continue to be one of the simplest ways to improve comfort, introduce acoustic control and create flexible living zones. With high quality glazing and steel look detailing, both Origin and Aluco offer long lasting solutions suited to a range of interiors.
