uPVC Windows
Our uPVC windows combine durability with energy efficiency, featuring A+ thermal ratings and multi-point locking systems for enhanced security. Available in casement, sash, and French styles, they suit both modern and traditional properties. Customisable colours and finishes allow seamless integration with your home's aesthetic while reducing heat loss and noise pollution.
Composite Doors
Engineered for superior insulation and security, our composite doors mimic the appearance of traditional timber without maintenance demands. They incorporate reinforced frames, 3D diamond-patterned panels, and high-security locks. Available in anthracite grey, white, and woodgrain finishes to complement any property style while increasing kerb appeal.
Conservatories
Bespoke conservatories create versatile living spaces using Ultraframe components with optional tiled or glazed roofs. Designs include Victorian, Edwardian, and lean-to styles adaptable for dining, lounging, or home offices. Thermally efficient glazing maintains comfort year-round while enhancing natural light and property value through tailored architectural details.
Aluminium Windows
Slim-profile aluminium windows offer contemporary aesthetics with exceptional strength-to-weight ratios. Powder-coated finishes in RAL colours provide corrosion resistance and design flexibility for modern properties. Their narrow sightlines maximise glass area while maintaining thermal performance through advanced polyamide thermal breaks.
Shutters
Made-to-measure plantation shutters deliver privacy control and insulation benefits through adjustable louvres. Available in hardwood, painted MDF, and moisture-resistant composite materials suitable for bathrooms and kitchens. Tier-on-tier and caf-style configurations balance light management with visual separation for both period and contemporary homes.

They seem happy to Risk Health and Safety and Fire Regulations. Their installation at our home is a Fire hazard as per their advice and they still are not able to resolve the issue
I am a new mum with a 4 month old at home. Fitter installed our windows and entrance door in December. After the installation of the door, we started to see issues with the installation. the door would jam shut and we would need 2 people to pull a few jerks to open it. Last week, I had to pull my husband out of a meeting to ask him to help me open the house door so I could leave to take the infant out. We have been

Horrible after service. The sales person was very keen to get order done with fantastic follow ups and loads of different touch points. After the order was placed we had many issues in regards to installations and after service. The door that was installed was fitted very badly and takes around 2 people to pull it open. After 6 weeks of calling and logging after service calls, the company is unable to give any help in regards to getting it serviced. The staff refuses to let you speak to a manager and all they can say is this is all I can do. We dont know when we can get around. I would

Excellent throughout from sales to fitting. During the sales meeting it was nice to have an adult conversation about windows and doors looking at brochures and thinking about what would work best for us, rather than the high pressure experience which we got elsewhere. The fitting itself was always going to present challenges. We ordered 6 windows and a front door with window surround. 5 of the windows were upstairs - 2 were bays (with integrated surrounds), 2 were in a Bathroom (tiled right up to the windows), and 1 was over a glass room where a slip could have spelt disaster. All the windows were
