Walsh Windows are a local Minnesota company, proudly manufacturing durable, high-quality windows for over 60 years. Backed by a lifetime warranty, Walsh Windows are built to last and come in a variety of styles and colors. This month, Walsh Windows is also offering a special promotion: a FREE upgrade to foam-filled sash and frames with ALL Walsh Window orders! Expanded polystyrene (EPS) is used and insulates up to 8% more than dead air. VOCs (volatile organic compounds) are also not off-gassed with EPS, unlike spray foam. EPS also does not shrink over time like spray foam and offers better indoor air quality. There are no air pockets in this foam, and it is a better value all around. Call today to take advantage of this amazing deal, and get your free foam filled sash and frames with all Walsh Window orders from Tony's Lifetime Exteriors: (320) 252-9086.
