Frequently Asked Questions: Commercial Curtainwall Glazing, Storefront Windows & Wet-Sealing in St. Paul, MN
Why do our office curtainwall windows in St. Paul leak at the horizontal mullions during driving rain?
As a curtainwall ages in Ramsey County's 110°F temperature swings, the exterior rubber wedge gaskets shrink at the corners by 1 to 2 inches, allowing wind-driven rain to flood the internal sill pan faster than the weep holes can drain. Wet-glazing the exterior glass-to-metal perimeter with structural silicone stops this permanently.
Why is there foggy moisture or white residue trapped between the panes of our St. Paul commercial windows?
Fogging inside a dual-pane commercial window means the perimeter polyisobutylene/silicone desiccant seal has ruptured, allowing humid air to enter and oxidize the Low-E silver coating. We replace just the failed Insulated Glass Units (IGUs) without tearing out your aluminum frames.
How do you stop ice from forming on the inside of aluminum storefront frames in St. Paul during January?
Older non-thermally broken aluminum frames conduct -20°F outdoor cold straight indoors. When replacing storefronts in Midway Industrial District, Energy Park, Westgate Business Park, Riverview Industrial Park (West Side Flats), Downtown Lowertown & Skyway Core, Red Rock Industrial District, Empire Builder Industrial Park, we install polyamide thermally broken framing paired with warm-edge glass spacers.
Can you replace broken or fogged glass on the 3rd to 10th floors of an office building in St. Paul?
Yes. Our union-trained high-reach glaziers utilize swing stages, 135-foot articulated boom lifts, and vacuum glass manipulators to replace large commercial IGUs safely across St. Paul.
