The 58F series offers a great alternative to storefront systems. We have designed this window to look like storefront but offer superior thermal performance, water resistance, and air infiltration. This window is capable of meeting Energy Star in all climate zones with our standard Low E glass. Gerkin’s internal water management weep system and optional nail fin make this window a great alternative to poor performing storefronts. The workmanship quality is also far superior to storefront because we build and glaze our windows complete in our climate-controlled factory, unlike storefront, which is assembled out in the weather.
When you want the look of storefront but prefer a higher performance level, look to Gerkin’s model 58F.
