A Premium New Door Range

For over 40 years, homeowners across Walsall, Wolverhampton and the wider West Midlands have trusted Leamore Windows for quality windows and doors. Alongside our popular uPVC and composite door ranges, we’re proud to add Origin aluminium doors: a premium door system for homeowners who want striking design paired with genuine performance.

Origin aluminium doors are manufactured from premium grade aluminium, a material prized for its strength, durability and slim sightlines. Large areas of glass bring more natural light into your home, while a choice of configurations allows you to create a door that works around your space. Whether you’re looking to open up a rear extension in Walsall or add a contemporary finish to a new-build in Cannock, Origin doors can be tailored to your requirements, including a wide choice of RAL colours.

From bifold and sliding doors to internal and French doors, the range offers a variety of ways to make better use of your space. With strong thermal performance, dedicated security features and an up-to-20-year guarantee, Origin combines the style you’re looking for with practical performance you can rely on.

OB36+ Bifold Doors Open Up Living Spaces

The OB36+ is Origin's ultra-slim bifold door, with 36mm sightlines and U-values as low as 0.78 W/m²K. Its folding panels open up a wide section of your home, connecting kitchens, living spaces and extensions with the garden while allowing plenty of natural light inside. Choose from Soho, Gallery or Georgian styling, over 150 RAL colours and a configuration to suit your opening.

Sliding Doors With Sightlines to Suit You

Our Origin sliding door range gives you three sightline options: the ultra-slim OS29+, the balanced OS44 and the more traditional OS77. Each system is designed to create expansive glazed areas and clear views of the garden, with different configurations and threshold options available to suit your home. This gives you the flexibility to choose the appearance and performance that works best for your space.

Choosing Between OS29+, OS44 and OS77

The OS29+ offers the slimmest sightline at just 29mm, making it ideal if maximising your views is a priority. The OS44 provides a balance between a slender profile and more traditional proportions, while the OS77 offers a classic appearance that can suit period properties. Each system has its own performance characteristics, security features and configuration options.

Internal and French Doors for Every Room

Origin's internal doors use slim 30mm sightlines to divide rooms without losing natural light, making them well suited to home offices, kitchens and living spaces. Origin French doors combine slim aluminium frames with a more traditional opening style, creating a contemporary take on a familiar design. With a wide choice of RAL colours and configurations available, you can create a look that complements your home.

Thermal comfort

Advanced thermal performance helps keep your home comfortable and efficient.

Thermal comfort

Origin's aluminium door systems are engineered with thermal efficiency in mind, helping to reduce heat transfer through the frame and glazing. Thermal performance varies across the range, with selected systems achieving U-values as low as 0.78 W/m²K when specified appropriately. This allows you to enjoy large areas of glass without overlooking the importance of comfort and energy efficiency.

Always use Leamore for new windows and always been impressed with their customer service. Never any issues if there’s a problem to be sorted. We had Chris round today to make an adjustment to our bifold doors and there was no issues getting a slot and Chris did a great job. Will definitely use Leamore for any future requirements

My experience with Leamore Windows was brilliant from start to finish. Cannot fault them at all and I am in love with my beautiful new blue front door. My house is instantly warmer too thanks to my lovely new windows. Fitters Dale and Harry were great, professional and nice to have around for three days. Thank you all.
