When it comes to designing a secure, energy-efficient, and stylish entrance to your home, few options match the excellence of Gerda doors offered by us, here at Affordable Windows & Construction Ltd (AWC Ltd).
Based in Slough and serving Berkshire and the surrounding Thames Valley region, AWC Ltd brings over 25 years of experience in premium window and door solutions — and our Gerda aluminium doors exemplify our commitment to quality, durability, and innovation.

1. Unparalleled Security and Strength
Security is one of the biggest selling points for Gerda doors. Crafted using a combination of high-grade steel and aluminium, these doors offer formidable resistance against forced entry. Our Gerda doors come with advanced locking systems — including multi-point locking, anti-prizing bolts, and even the optional Tedee smart lock — to provide peace of mind for homeowners.
Gerda’s engineering isn’t just about brute strength. Their doors are rigorously tested — for example, their BM Trada certified models have passed fire-safety and mechanical resistance tests. In short: these are not just doors, but serious protective barriers.
2. Exceptional Thermal Performance
Gerda doors are designed with energy efficiency in mind. Thanks to their advanced build, some models achieve a U-value as low as 0.74 W/m²K, which is extremely impressive for front doors.
This reduced heat transfer doesn’t just mean a warmer home — it translates to lower energy bills, less reliance on central heating, and a significantly reduced carbon footprint. Plus, with good insulation performance, these doors can also help with soundproofing, making your living space quieter and more peaceful.

3. Durability Meets All-Weather Resilience
One of the standout features of Gerda’s aluminium and steel construction is its resistance to warping, weather damage, and long-term wear. Our Gerda doors can withstand the unpredictable British weather — from driving rain to freezing winters — without compromising performance.
Aluminium, by nature, is highly resistant to corrosion, and when paired with steel reinforcement, the result is a door built to last for decades with minimal maintenance.
4. Low Maintenance, High Reward
Aluminium doors are famously easy to care for — a gentle wash with soapy water every once in a while is generally enough to keep them looking pristine. Unlike wooden doors, there is no need for repeated painting, varnishing, or worry about rot. This long-lasting finish is one of the key reasons aluminium is such a beloved material for modern homes.
5. Beautiful Customisation & Aesthetic Appeal
Gerda doors don’t just perform well — they look good doing it. We offer a rich variety of designs, finishes, and styles to suit any home. Whether you want a sleek, flush ALTUS door, or a more classic entryway, there are options to match.
Gerda’s ALTUS aluminium range, for example, offers very slim profiles and can be custom-painted in any RAL shade, giving homeowners creative freedom while maintaining high performance. The design ensures a seamless, continuous leaf, giving your front door a minimalist, high-end appearance that elevates your home’s curb appeal.

6. Sustainable & Environmentally Responsible
For conscious homeowners, Gerda doors are a compelling choice. Aluminium is highly recyclable, so when the door eventually reaches the end of its life, the material can be reused without degrading its properties.
Moreover, the exceptional thermal efficiency of Gerda doors helps reduce energy usage, which in turn lowers your home’s carbon footprint.
