Frame, Colour, and Glass Options
DuraJoin bifolding doors are built for more than just looks. Every unit is engineered for lasting performance and tailored to fit your exact preferences.
Our frames use slimline aluminium profiles with full thermal breaks. These deliver strength and energy performance without the bulky sightlines of older systems. You get more glass, cleaner edges, and reliable insulation year-round.
Colour options include any RAL finish, with the ability to specify different colours for the inside and outside of the frame. Whether you want crisp white, bold black, or something that complements your interiors, it’s all made to order. Dual-colour frames give flexibility across traditional and modern builds.
Glazing choices are just as flexible. We offer double and triple glazing, laminated safety glass, and solar control units to reduce heat gain and glare in exposed spaces. If noise is a concern, acoustic-rated glass is available to minimise external sound.
Our systems are designed around your layout. Choose between two-panel up to seven-panel configurations, opening in or out, with smooth running tracks and no sagging over time. You can also specify flush thresholds for step-free access, perfect for kitchen extensions or rear lounges leading to garden patios.
All units are fully sealed and weather-tested for high performance in rain, wind, and temperature shifts. These aren’t just style pieces. They’re built to last.
How We Work
At DuraJoin, our bifolding door process is engineered for clarity, quality, and consistency. From your first call to the final seal, every stage is handled by professionals who know your area and understand the requirements.
Here’s how we get it right.
Survey and Advice
Every project starts with a site visit. Whether you’re in Hitchin, North London, or Greater London, our team visits your property to inspect the opening and surrounding structure. We check access points, daylight angles, structural support, drainage conditions, and opening orientation.
This isn’t a sales pitch. It’s a technical survey designed to ensure the correct bifolding system is specified for your property. We also identify any early issues that might require structural support or special drainage detailing.
Design and Quote
Next comes design. If needed, we’ll create CAD drawings to show the layout and panel breakdown, especially useful for new builds or extensions. Every quote is transparent and includes supply, installation, site trimming, sealing, waste removal, and finishing.
You get a fixed figure, not a rough estimate. If planning permission or building control is involved, we supply the specs and drawings required to move things forward.
Manufacture
Once approved, we manufacture your bifolding doors to exact specification. That includes your chosen number of panels, finish, opening direction, glazing, threshold format, and colour.
All our doors are made using high-performance, thermally broken aluminium and precision-engineered running gear. Each system is quality tested before it ever leaves the workshop.
Delivery and Install
We don’t outsource installation. The same DuraJoin team that surveyed your opening fits your doors.
We deliver directly to site. The install typically takes one to two days depending on access and prep requirements. Our team seals, trims, aligns, and tests the system for airtightness, watertightness, and smooth operation.
You don’t have to chase multiple trades. We coordinate directly with any builder or contractor already working on your site and keep disruption to a minimum. Clean-up is part of the job. Nothing is left behind.
Aftercare and Warranty
You’ll receive both product and installation guarantees for peace of mind. We also offer optional annual maintenance checks to keep your doors operating as new and ensure seals, rollers, and frames stay protected year after year.

Frequently Asked Questions
Q: Can bifolding doors be installed in a small opening?
Yes. A two-panel bifold is ideal for smaller openings. It folds compactly to one side, providing clear access and good ventilation without needing large space. We tailor each unit to your measurements to ensure it fits cleanly and operates smoothly, even in compact openings.
Q: Are they secure?
Yes. All our bifolding doors come with integrated multi-point locks, reinforced hinges, and toughened safety glass as standard. For higher security needs, we offer laminated glazing or full Secured by Design certified specifications, trusted by architects and developers across London and Hitchin.
Q: Do I need planning permission?
In most cases, no. Bifolding doors at the rear of a property typically fall under Permitted Development. We check each property type and location during the site visit. If planning or building control is required, we’ll flag it and assist with the paperwork.
Q: How long does installation take?
Most bifolding door installations take 1 to 2 days from delivery to completion. This includes fitting, sealing, and finishing. If any structural work is needed, we’ll coordinate with your builder or handle it ourselves to keep things on schedule with minimal disruption.
Q: Will it get too hot in summer?
No. We offer solar control glass options designed to reflect heat while letting in natural light. You can also combine solar and low-g coatings for south-facing walls or exposed areas. These reduce glare and overheating while maintaining thermal performance in winter.
Q: Can it match the rest of my windows?
Yes. All frames are finished in your chosen RAL colour, and we offer dual-colour options to match interior and exterior styles. We can also replicate detailing to match nearby windows or doors, whether it’s traditional framing or a modern architectural look.
