Get clear answers from GFD Homes on doors, windows, bifolds, and roof lanterns. Expert advice to help UK homeowners choose with confidence.

In Part 5 of the “Your Questions Answered” series, GFD Homes continues to tackle the real questions UK homeowners ask about doors, windows, and glazing. From durability to style, security to energy efficiency, this guide provides straightforward answers to help you make confident decisions for your home.
Composite doors are a popular focus, with many asking if they warp like timber. The answer is no — their GRP skin and engineered core resist seasonal changes, ensuring long-term stability. Entrance doors with glass panels are another frequent query, and GFD offers a variety of frosted, decorative, and reinforced glazing options for both light and security.
Bifolds, sliding doors, and aluminium products also feature prominently. GFD explains why bifold doors require track systems, why aluminium is the preferred choice for sliding systems, and why aluminium front doors won’t rust. Homeowners also learn that while aluminium windows cost more than uPVC, they provide longevity, slim sightlines, and modern design.
Finally, the guide compares the best materials for UK front doors — uPVC for affordability, composite for all-round performance, and aluminium for premium style.
With transparent advice and supply-only solutions, GFD Homes helps you choose products that perform, protect, and look great for decades.
