Review on 🔁 M D Building Products 71548 Interchangeable by David Blackstock

Took a page from my late father's guidebook and bought 2 rolls for about ten dollars. You could spend thousands on new windows, but this material keeps the cold out and keeps you cool in the summer. It has 6 rows in height and hides well behind the blinds. I only needed 2 of the 6 rows so I had enough for other problem areas. Each roll gave me 3x the length of a roll and is easy to install. Simply slip into the slots around each window and the problem is solved. It is so easy!
