Two is better than one - no question!

Don’t be fooled into thinking that all sealed units are the same – they are not. And it’s not just the type of glass, but the way the units are sealed.

All GLASSOLUTIONS sealed units feature a double seal which helps you guarantee the quality and energy performance of your windows and doors long term – and keep customers happy and coming back.Key benefits: Two seals mean you are always protected.Unlike units with one seal, should we have an unlikely failure on a seal there is always a backup in place - giving you peace of mind that you won't have problems in the future.


  • Our secondary seal also gives the IGU its structural strength, ensuring there is no chance of movement once installed. Especially important in larger units used in patio and bifold doors.
  • The first seal is always visible so you can always make sure the seal is intact, even when it’s installed into a frame - giving you peace of mind the unit will perform.
