Loving my new windows

I’m loving my new Winplex windows. I got them installed just in time for that super hot day yesterday – even though it was 44 degrees outside, I barely used my A/C all day! They look great, and the built in fly screens mean that I can have the doors and windows open without letting in any insects. The Winplex team kept in contact from ordering, through installation and then followed up with me afterwards. I couldn’t be happier.
