Style, security and warmth for your Leeds home

Our aluminium windows are well-known for their slim profiles, which gives them an incredibly clean and beautifully sleek appearance whilst allowing more light to enter into the home. They also come fitted with outstanding polyamide thermal breaks, dramatically reducing heat transfer, helping them to achieve Window Energy Ratings of ‘A’. With them, you can warm up your home and potentially knock down your energy bill significantly.

As is the case with all our windows and doors, they utilise a range of impressive security features. Reinforcement around the frame is provided by an advanced multipoint locking system, and they can also be internally beaded, preventing the glazing from being removed externally. With our aluminium windows, you can keep your home as it should be – free from intruders.

    PLANITHERM GLASS FOR A POWERFUL THERMAL PERFORMANCE

    We offer high-performance glazing from glass specialists Planitherm. Energy Standard glass, which is our standard option, is 56% more energy-efficient than a double glazed unit filled with air. However, for additional benefits like enhanced security, further noise reduction and fade protection for your furniture, you should consider Comfort or Comfort Plus glass instead.

    Long-lasting style and performance

    Not only is aluminium immensely strong and sturdy but it also has an anti-corrosive layer. This means that aluminium windows will not warp or twist as time goes on, and nor will they succumb to rust. Combining its natural durability with one of our high-quality installations, they’ll keep your home free from the best and worst of the British weather for years to come, whilst you needn’t worry about their quality diminishing. Aluminium windows from TWS are built to last and then last some more.
