Fire Rated Internal Doors in a Berkshire Home Renovation

This project involved the installation of Aluprof fire rated internal doors within a private residential home finished to a high contemporary standard. The brief was clear from the outset.

The homeowners required certified fire protection, but did not want traditional steel fire doors. Instead, they wanted a bold, design-led internal door that would become a feature within the home while meeting modern fire safety requirements.

Aluprof Fire Rated Internal Doors – Fire Protection with Contemporary Design

LB Window Systems specified Aluprof fire rated aluminium doors to deliver exactly that balance. Aluprof products are widely specified all over the world in dwellings and commercial buildings, with an aluminium range that is superly designed and engineered.

Aluprof fire rated aluminium internal doors were selected for their unique construction. Unlike most fire rated systems on the market, which rely heavily on steel, Aluprof uses a bespoke mix of materials within aluminium profiles to achieve fire resistance. This is significant, as aluminium does not naturally have a fire rating.

Whilst aluminium usually has no fire rating and has to be steel where 30, 60 or 90 minute fire protection is required, Aluprof doors are aluminium. The profiles are heavily reinforced internally with special materials, sealants and foams, meaning the aluminium retains its integrity in a fire, just like steel.

In this home, the doors sit between key living spaces and are seen and used every day. The requirements were:
• Certified fire rated performance
• A strong architectural presence rather than a traditional steel look
• Glazed panels to allow light to flow between rooms
• A flush, threshold-free installation to preserve the parquet flooring

Internal fire doors were usually treated as a regulatory necessity rather than a design opportunity. However, with so many of us re-configuring the inside of our homes, what were previously fire-retardant or resisting walls, when knocked down still need to provide protection. As a result, fire rated internal doors are now widely used in residential project. They are not just for commercial buildings.

The homeowners wanted the doors to feel intentional, premium and fully integrated into the interior scheme.

The result is a fire rated door that offers:
• Slim but bold aluminium sightlines
• Large glazed panels with fire rated glass
• A contemporary colour finish chosen to complement the interior décor
• The option for single or double glazed configurations depending on the application

These particular doors have been installed without a visible threshold, allowing the wood parquet flooring to run uninterrupted between rooms, an important design detail in this home.

Engineering and detailing

As the open-door images show, the quality of engineering is immediately apparent. The frames are precisely manufactured, the hinges are substantial yet discreet, and the locking system feels solid and reassuring in use. These are not lightweight internal doors. They are robust, secure and purpose-built to perform in the event of a fire.

Despite this strength, the doors operate smoothly and sit cleanly within the openings, reinforcing the overall sense of quality.

Fire rated performance and system flexibility

Aluprof offers one of the most comprehensive ranges of fire rated aluminium systems available, suitable for both residential and commercial use. Depending on the project requirements, fire resistance classes range from EI 15 up to EI 120 for vertical applications, with roof glazing systems achieving REI30 and REI45.

The range includes:
• MB-60E EI – Internal fire resistant partitions and doors up to EI30
• MB-78EI – Fire rated partitions and doors from EI15 to EI90
• MB-78EI DPA – Automatic fire resistant sliding doors (EI30)
• MB-86 EI – Fire rated windows, doors and partitions
• MB-118EI – Fire rated wall systems achieving EI120
• Fire rated curtain walling systems and glazed fire roofs

Why Aluprof was the right choice

These Aluprof fire rated internal doors have become a focal point within the home. They provide reassurance in terms of safety, while enhancing the interior with strong sightlines, quality materials and precise detailing.

The absence of a visible threshold and the uninterrupted parquet flooring underline the care taken in both specification and installation.

This project demonstrates how fire rated internal doors no longer need to look utilitarian. With the right system and expertise, they can be solid, secure and compliant, while still contributing positively to the design of a modern home.

At LB Window Systems, we specify and install advanced fire rated aluminium door systems for homes across Hertfordshire and the Home Counties. And we are fully trained in the installation of these doors that are designed first and foremost for safety. This project shows how Aluprof fire rated internal doors can combine protection, performance and contemporary design without compromise.
