We offer a huge range of over 40 colour and frame options, as well as numerous different glazing choices for you to create the right fit for your home. Look no further than Sealtight Windows NE Ltd for your new windows.

Kommerling UPVC windows offer a high standard of quality and innovation with a desire to make change in the industry. We strive to improve the energy efficiency of homes across Yarm, working with our customers to help reduce our carbon footprint, preserve natural resources and help to tackle climate change.

Our windows no longer contain lead additives: these have been replaced with recycled materials, which help us maintain long-term sustainability as a company. The efficiency of our windows is not compromised by making them environmentally friendly; in fact, you’ll find your heating bills could be significantly reduced when you buy from Sealtight Windows NE Ltd! By taking these sustainability measures, we are proud to offer the most energy efficient windows you can buy in Yarm.

While most installers use an outdated and inefficient 3 chamber profile, our windows use an innovative patented 5 chamber profile, making them far more thermally efficient than those of our competitors. Not only are our windows energy efficient, they are also beautifully designed, using soft lines and low-line gaskets to create a slimmer profile. Our windows look clean, contemporary and beautiful, and can provide a new lease of life for your home if your windows are looking a little tired.

Our windows come with numerous excellent features as standard:

  • A profile depth of 70mm
  • A 5 chamber profile, which allows increased insulation
  • Reinforced profile
  • Finished in a choice of 44 different colours
  • High security from internal beading
  • A 25 year Colourfast guarantee

We partner with Kommerling, providing our customers with windows that can be tailored to their exact requirements. Whatever you’re looking for, Sealtight Windows NE Ltd offer a huge range of customisation options, and will be able to provide you with beautiful windows that complement your home.
