Door Supply & Installation Across London & Hertfordshire

Choosing a new door is about more than finding a design you like. It needs to suit your property, perform reliably throughout the year and make everyday living easier. Aurora Glazing supplies and installs composite, aluminium and uPVC doors from its Welwyn Garden City base, serving homeowners across Hertfordshire and selected London areas.

Whether you’re renovating an older property, planning a new-build home or extending your living space, we’ll help you consider the right combination of materials, glazing, hardware and opening arrangements.
Choosing the Right Front Door
Your entrance is one of the first things visitors notice, but appearance shouldn’t come at the expense of security or insulation.
Composite front doors are a popular choice for their insulated construction and variety of traditional and contemporary designs. Aluminium entrance doors offer clean architectural lines and durable finishes, while uPVC doors provide a practical, low-maintenance alternative.
Consider the complete doorset, including its frame, locking system, glazing and weather seals, rather than comparing door panels alone.
Bifold, Sliding or French Doors?
For extensions and garden-facing rooms, the way your doors open matters just as much as their appearance.
Aluminium bifold doors are particularly useful when you want several panels to fold aside and create a wider clear opening. Sliding patio doors offer larger individual glass panels without requiring space for folding leaves. French doors provide a familiar double-opening arrangement that works beautifully with both modern and traditional properties.
If preserving garden views is your priority, consider the frame sightlines when the doors are closed. If access and ventilation matter more, look closely at opening configurations, thresholds and panel arrangements.
Security, Insulation & Glazing That Matter
Modern external doors should help maintain indoor comfort while providing dependable protection against the elements.
Depending on the selected system, available features include thermally broken aluminium frames, insulated composite cores, multi-point locking, safety glazing and different threshold options.
We recommend reviewing the performance of the complete door system, particularly its thermal efficiency and applicable security certification, rather than relying solely on individual component specifications.
Professional Door Survey & Installation
A quality door deserves equally careful installation. Accurate measurements, opening preparation, correct frame alignment and suitable sealing all contribute to reliable operation and long-term performance.
Our supply and installation process considers your property’s existing structure, preferred design, glazing requirements and available opening space before the final product specification is agreed.
For new extensions, discussing door dimensions and thresholds early can also help avoid unnecessary complications later in the project.
