Lets talk spacers
I am replacing all my windows in my home (59 of them!)
I have it narrowed down to 2 companies...one uses the XL edge spacer from Cardinal, while the other uses the Superspacer.
I understand that the XL is not as warm as the SS on the edge,but the XL claims lower failure rates?
One is more durable,the other is more efficient?
If they were priced equally,which would you choose?
Would you pay a premium for either?
Is there a link where these products are compared,other than the manufacturer's own?
Thanks for all your input
