Tec Glass Slimline Heritage Aluminium Windows Tec Glass offer a slimline aluminium window that we custom build with a range of furniture and highest security available Our aluminium window system is designed as an extremely slim-line thermally efficient replacement for steel windows. These replacement windows use the latest Polyamide thermal break technology, replica steel look-a-like profiles and are still a fraction of the cost of steel windows. Due to their high specification the aluminium windows are suitable for NEW BUILD as well as replacement windows or refurbishment projects - they also can (and have been) approved for use in Grade II listed buildings and conservation areas. We are currently in the process of designing new back plates and revising our range of door furniture for our Aluminium Windows. We will post more example pictures of these very shortly on the web site to give you ideas and be able to compare with windows in your existing property. If you are looking for long lasting and secure replacement windows they should definitely be considered versus window restoration. |
