Introduction: Doors and Windows Matter More Than You Think
When it comes to upgrading doors and windows, most homeowners feel the same mix of excitement and hesitation. With so many options — from composite front doors to aluminium windows — it’s easy to get stuck comparing security ratings, U-values, or guarantees.
At GFD Homes, we’re asked the same questions daily. To make things easier, we’ve put together clear answers to the six most common queries. This way, you can make confident choices that fit your home, lifestyle, and budget.
Education
What are the benefits of composite doors for home security?
Security is the number one priority when choosing a new door. Composite doors are designed to deliver strength and peace of mind:
- A GRP (glass-reinforced plastic) skin resists knocks and scratches.
- A solid engineered core provides rigidity.
- Multi-point locking secures the door in several places.
- Many models carry Secured by Design accreditation, a police-backed standard.

What should I look for when choosing bifold doors for my extension?
If you’re planning an extension, bifold doors are a popular way to bring light and a sense of space into the home. But what exactly should you look for? Homeowners often ask us this very question.
Here are the key things to consider:
- Thermal efficiency: Look for low U-values to ensure your extension stays warm in winter and cool in summer.
- Sightlines: Slim frames give you bigger glass panels and uninterrupted views.
- Security: Multi-point locks and tough glazing are essential.
- Threshold options: Low thresholds create a seamless flow from indoors to outdoors.
- Finishes and colours: Match your bifolds to your existing windows and doors for a cohesive look.

Comparison
How do uPVC windows compare to aluminium windows for durability?
This question comes up a lot — and with good reason. Both uPVC and aluminium are strong contenders, and the right choice depends on your priorities.
- uPVC windows: Cost-effective, excellent insulation, and very low maintenance. Lifespan is typically 20–25 years with little upkeep.
- Aluminium windows: Slimmer frames, more contemporary look, and longer lifespan (30+ years). They are incredibly durable and resistant to warping or fading.
If your priority is budget and insulation, uPVC is ideal. If you want longevity and a premium look, aluminium may be worth the extra investment.

Which composite doors are most energy efficient?
Energy efficiency is a hot topic, especially with rising energy bills. Homeowners frequently ask us which doors really make a difference.
Composite doors are among the best performers thanks to:
- Insulated cores that trap heat.
- Weather seals that keep draughts at bay.
- Efficient glazing options that reduce heat loss.
The most energy-efficient composite doors achieve U-values as low as 0.9 W/m²K, outperforming older timber or uPVC designs.

Research
Are there home improvement brands offering long guarantees on windows and doors?
Yes — but not all guarantees are created equal. While some national brands advertise long coverage, small print often limits what’s included.
At GFD Homes, we prefer clarity. Every product page clearly lists the guarantees for doors and windows, so you know exactly what’s protected before you buy.
How long are the guarantees on composite doors from leading UK suppliers?
This is a question we’re asked often — and rightly so. Composite doors are a significant investment, and you want confidence in their lifespan.
- Many leading suppliers now offer 10-year guarantees as standard.
- Some brands extend coverage for colour stability or hardware.
- GFDHomes provides clear guarantees with every composite door, so you know you’re covered for both performance and finish.

Frequently Asked Questions About Doors and Windows
1. What type of door is best for UK weather?
Composite and aluminium doors are excellent for the UK climate. They resist warping, swelling, and cracking, and maintain a good seal even in damp or windy conditions.
2. How do I know if my old windows need replacing?
Signs include draughts, condensation between glass panes, difficulty opening/closing, or visible frame damage. If energy bills are rising, inefficient windows may also be the cause.
3. Are aluminium windows colder than uPVC?
Not anymore. Modern aluminium windows include thermal breaks that stop heat transfer, meaning they can be just as warm and efficient as uPVC while offering slimmer frames.
4. Do guarantees cover both doors and windows?
Yes, but coverage varies by brand. At GFD Homes, we clearly state product warranties so you know how long your door finish, glazing, or frame is protected.
5. Can I mix and match materials?
Absolutely. Many homeowners choose aluminium windows with a composite door (or vice versa). The key is to coordinate colours and finishes for a cohesive look.
