Climate Seal™ Benefits

The ‘Invisible’ Flexible

Our flagship product, is an interior magnetic insulating window system. It is not a prime or replacement window. The premise is simple. It is to take the benefits of the existing window and improve it without compromising the look of the opening. As a homeowner or property owner you have to ask yourself some of these questions.

  1. Do I like the look of my existing window?
  2. Do I want to incur the expense and hassle of replacement?
  3. Do I even know what I want?

Aside from the last question, which may never be answered, you should seriously think about questions 1 & 2. Let’s face it, there are millions of aesthetically pleasing windows – from an old wooden double-hung to a steel casement window – that just do not perform as they should. Whether it is air infiltration, drafts, noise, cold, heat, damaging UV rays, dust and/or pollen that is your problem, the Climate Seal™ family of products is for you. It can help with:

  • Cold
  • Condensation
  • Noise
  • Summer Heat Infiltration
  • Damaging UV Rays
  • High Utility Bills
  • Dust and Pollen

Climate Seal Is NOT…

  • An exterior storm window
  • A prime replacement window

Climate Seal Is…

  • A Custom Manufactured, Insulating Window that Installs Within or Over The Existing Window Cavity
  • Virtually Invisible in Place
  • Maintains The Original Integrity of The Original Window – No Tearing Out & No Disruption
  • Available in Wood Veneers and Custom Colors
  • Available with Circle Tops and Bowed Windows

This is how easy it is to put up your Climate Seal™ Window Insert. Just drag the window insert on to the window frame and its magnets guide it into place. You may need a second hand putting up the real thing.
