Heritage Doors

Introducing our Heritage entrance door at Herts Glass, a fully aluminium masterpiece that reimagines a design classic rooted in the early 20th-century Art Deco and Modernist architectural movements. This contemporary take on a timeless aesthetic delivers unparalleled style and performance for Hertfordshire properties.
The industrial elegance of the slim frame is perfectly suited to aluminium, which surpasses its steel predecessor with superior durability, energy efficiency, and full recyclability. Unlike steel, aluminium resists rust and requires minimal maintenance, ensuring lasting beauty and functionality.
With versatile configuration options, including fan and side lights, the Heritage Door allows you to create a cohesive heritage aesthetic across various door opening sizes and styles, from single doors to French doors with multiple fan lights. Whether for refurbishments or new builds, these doors elevate any property with their authentic steel-look charm.
For homeowners, the Heritage Door balances form and function effortlessly. Its slim 51.7mm sightlines deliver a striking geometric design while maximising light transmission, elegantly framing your outdoor space. With market-leading U-Values of 1.4 W/m²K, these doors are fully compliant with Part L Building Regulations for refurbishment projects, ensuring exceptional thermal efficiency to keep your home warm and energy bills low. Each installation is registered with Certass, guaranteeing quality and peace of mind.


Often referred to as the handshake of the building, our period-correct door handles exude confidence and comfort with every interaction. Crafted to complement a wide range of property styles, from refurbishments to new builds, they are available in Matt Black, Antique Bronze, Heritage Black, and Heritage Grey finishes, ensuring a perfect match for your heritage aesthetic.
Our sympathetically engineered slim door and fixed light transom seamlessly aligns the horizontal lines of the door with screen work on either side. This not only enhances the visual appeal but also streamlines fabrication by eliminating the need for dummy sashes or astragal bars, delivering a clean and authentic heritage look.

Heritage Doors are equipped with advanced weatherproofing technologies, rigorously tested to British standards to provide a robust shield against the unpredictable British weather. The innovative polyamide thermal break technology ensures exceptional energy efficiency, preventing heat loss and maintaining a comfortable interior.
Security is paramount, with one of the most robust multi-point locking systems available, fully compliant with PAS 24 standards. High-security cylinders come as standard, and the doors’ strong 45-degree mitre and crimped sash corners, supported by our V-block and jaws, ensure durability for doors up to 2m wide and 2.3m high, offering unmatched protection for your home.
