A Premium Alternative to uPVC

Origin is a UK manufacturer of premium aluminium windows and doors, and Leamore Windows is proud to bring the range to homeowners across Walsall, Sandwell, Dudley and the wider West Midlands. If you are considering aluminium windows for your home, Origin combines sleek design with strength, security and thermal performance.

Slim sightlines are one of the defining features of the range. Aluminium’s strength allows Origin to create slimmer profiles while maximising the glazed area, helping to bring more natural light into your home and create clearer views of the outdoors. The result is a sleek, contemporary look that works well in both new homes and older properties, whether you need a single casement window or a larger run of glazing across an extension.

Strength and security are also important parts of the Origin range. Both the OW70 and OW80 are designed to meet PAS 24 and Secured by Design requirements, with multi-point locking systems and robust aluminium frames. Origin windows are manufactured in the UK and can be customised with over 150 RAL colours, including dual-colour options, so you can create a consistent look inside and outside your home.

As your local Origin partner, here at Leamore Windows we can talk you through the different options and help you choose the right window style and configuration for your property.

OW70 Windows: Slim Sightlines, Maximised Glazing

The OW70 is Origin’s slimline aluminium casement window, designed with a 65mm sightline to maximise the glazed area and provide clear views. Its slim profile allows more natural light into your home while maintaining the strength and thermal performance expected from a modern aluminium window. Finished with an external flush casement, the OW70 suits contemporary and traditional homes across the West Midlands.

OW70 Security Features and Colour Options

Security is built into the OW70, with a PAS 24-certified multi-point locking system helping to protect your home without compromising its slim design. The window is available in fixed, casement and bay configurations, with over 150 RAL colours to choose from. Dual-colour options are also available, allowing you to create a different finish inside and out.

OW80 Windows: Premium Performance, Flush Casement

The OW80 is Origin’s premium aluminium window, combining a flush casement design inside and out with enhanced thermal performance. Its clean, modern appearance creates a consistent look from both sides of the window, while the thermally broken profile helps improve energy efficiency. An Aerogel option is also available for projects where thermal performance is a priority.

OW80 Thermal Performance and Large Glazing

The OW80 can achieve U-values as low as 0.8 W/m²K when specified with triple glazing and Aerogel, helping to reduce heat transfer through the window. Its strong aluminium profile is also suitable for larger configurations, including bay and gable windows, making it well suited to extensions, renovations and new homes where larger areas of glazing are required.

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.
