Why Windows Often Receive Too Much—and Too Little—Attention Few elements of a home renovation attract as much attention as new windows.

Triple Glazing Isn’t Automatically the Right Answer One of the most common misconceptions surrounding modern glazing is that triple glazing is always the superior choice.

Mistake #1: Assuming Every Window Performs The Same Job It is easy to understand why windows are often compared primarily on price.
