Kohltech windows are some of the best windows that you can get in Canada. They are 1 of 3 window and door companies in Canada that qualify for passive house energy rating. 

All the parts are Canadian made and for us here in Alberta are all locally assembled in Edmonton, Alberta. 
 

The other thing that makes Kohltech so appealing for us at KDM is their Lifetime Warranty on their supreme window and door line. Yes, other suppliers have a limited lifetime warranty. However, where Kohltech out does them is here, the lifetime warranty is completely transferable!* That means if you buy a house with Kohltech windows you don't need to worry about warranty, it transfers to you!! If you sell your home to another they recieve the warranty and that is a great selling feature! 

This is actually a warranty that is very rare to see in the industry.  

Kohltech windows have some of the highest R value ratings you can find and the windows are renovation grade.  

Their windows and doors come in an array of sizes (custom and standard), styles, colours, and decorative features such as bars.  

If you would like to see a window or a door in person you can stop by our office and see these gorgeous products for yourself!
