58F | Fixed Aluminum Window

58F Fixed Aluminum Window

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.

58F Series | Features

Rated Fixed Window

Rated Fixed Window: AAMA CW35/CW45-LC40/LC50 fixed window.

Thermal Breaks

Thermal Breaks: This window features a 4 5/16" frame depth with a thermal bar thermal break. This thermal break system helps this window achieve u-values as low as .30 (3/16" or 1/4" glazing required).

Double Wall Mainframe

Double Wall Mainframe: This feature gives our window more structure and stability than our single wall window and storefront competitors.

Dual Wall Drainage

Dual Wall Drainage: The dual wall allows us to build in an internal water drainage system. This system will prevent water from seeping into the building wall, unlike storefront which must use sill flashing with end dams.

Equal Sight Lines

Equal Site Lines: When horizontal and vertical rails intersect, the sight lines will remain equal in windows up to 99" tall. Even when windows are field mulled, the field mull will look like a factory mull. Other mull options available up to 144" tall.

Interior or Exterior Glazed

Interior or Exterior Glazed: This option allows the window to be ordered as interior or exterior glazing. The standard glazing is to the interior.
