About Technal UK

The Technal brand is part of the substantial Hydro Group, and also includes the Wicona German brand of aluminium systems as well as SAPA. SAPA in the UK was a long-established name and now this entire brand and its products is integrated into the Technal brand. In other words, SAPA is now Technal. Despite this, many of the popular and well known SAPA products are retained within the Technal brand.

The Technal name generally has a long-established reputation for innovative doors, windows and curtain walling. Technal UK products are found in numerous developments of housing, retail, commercial, transport, education and other sectors.

Moreover, Technal UK is heavily involved in the specification of glazing, working with construction firms, architects and specifiers.

Technal UK aluminium systems and products

The Technal UK range comprises residential and commercial systems of curtain walling, aluminium windows, sliding and bifolding doors and commercial doors, shopfronts and screens.

Aluminium Windows by Technal UK

Twelve aluminium window systems comprising both established SAPA and Technal brands now form the aluminium windows collection by Technal UK.

Crown Residential Windows

Originally part of the SAPA range of windows, Crown Residential windows comprise fixed, side hung, top hung and steel-look windows. The Crown name also replaced the popular Monarch Aluminium Windows system from the 1990s used extensively in the UK under the previous Monarch Aluminium name. Crown also takes many of the original styling cues from Monaframe such as the softline outer frame detail.

Soleil FY65

A Technal brand, Soleil FY65 is a very advanced aluminium window product offering both minimal-framed or near-hidden opening sashes as well as significant opening window sizes up to 1.4m wide and 2.5m high. Soleil FY65 is predominantly a commercial system with a 65mm frame depth.

A more standard version of the product has a larger visible opening sash design, but with the same features of large sizes, hidden drainage and contemporary styling.

Dualframe 75

Another well-known SAPA name, Dualframe 75 comprises the standard and SI variants. This system has casement, fixed, tilt and turn and reversible aluminium windows. Where enhanced thermal performance is required, Dualframe 75 SI provides an excellent aluminium windows solution. It’s also an externally beaded system meeting current security credentials.

Also available within the Dualframe 75 collection is the Aluminium Balcony Window. A version of the existing tilt and turn window product, this provides inward opening windows, single or double doors. It’s ideal for balcony applications, Juliet balconies and particularly good where window rebates need combining but without the conventional coupling or dummy sash method of other systems.

Dualslide Sliding Windows

Also part of the SAPA collection before integration into the Technal brand, Dualslide are high performance sliding windows available in both horizontal and vertical opening designs. Horizontal sliding windows go up to 1.5m high and vertical sliding up to 2.7m high providing exellent large window solutions in a modern sliding sash product.
