FAQ’s About Our Double Glazed Exterior Doors

Find answers to common questions about our versatile range below.

How is a double-glazed external door different from a single-glazed door?

Single-glazed doors use only one pane of glass, offering minimal insulation and allowing heat, cold and noise to pass through easily.

In contrast, a double-glazed external door features two panes separated by an insulating gap. The result is superior thermal insulation, reduced noise and improved security.

For even greater efficiency, triple glazing adds a third pane and extra insulating layer, further boosting heat retention, sound reduction and overall door security.

What are the benefits of choosing a double-glazed external door?

Double-glazed external doors are more effective at retaining heat. They improve your home’s insulation, reducing your heating bills. The toughened safety glass we use adds strength and enhances security, securing your property while maintaining warmth and light flow throughout your home.

Can I upgrade my existing external door to a double-glazed door?

Yes. In many cases, existing timber door or window frames can be upgraded to include double glazing. The retrofit process is designed to preserve your door’s original look while improving insulation and energy efficiency.

Typically, this involves:

1. Carefully removing the old single glazing.

2. Routing a slightly deeper channel in the frame to make space for the new double-glazed unit.

3. Fitting fresh timber beads to secure the glass for a neat, durable and weather-resistant finish.

The result is a subtle, effective change that enhances performance without noticeably changing your door’s overall appearance.

What maintenance do double-glazed external doors need?

1. Wipe frames and glass with warm, soapy water every 6–12 months.

2. Check seals for wear.

3. Regularly lubricate hinges/locks to maintain insulation and smooth operation.
