5900 | Single Hung Aluminum Window

5900 Single Hung Aluminum Window

This single hung offers great performance with a smooth operation. The 5900 is highlighted by block and tackle balances, tilt-in sash, recessed tilt latches, automatic sill locks, and dual pull rails. Our air infiltration is an amazingly low .03! This great performance is enhanced by features like a sloped sill, dual weatherstripping, and a center interlock.

Gerkin’s strength is in the ability to perform at a very high level in air infiltration, water resistance, and thermal performance. One of the key options Gerkin offers is factory mulling for combination windows such as hopper, awning, casement, and fixed windows. This option speeds up installation time and reduces field installation errors.

5900 Series | Features

Rated Single Hung Window

Rated Single Hung Window: AAMA LC-50 rated single hung window.

2 3/8" Thermally Broken Frame Depth

2 3/8" Thermally Broken Frame Depth: We use a thermally broken frame and sash for improved thermal efficiency.

Polyethylene Seal Pads

Polyethylene Seal Pads: Gerkin ensures a tight fit at all sash and frame corners to seal out light, air, and water.

Integral Nail Fin

Integral Nail Fin: Nail fins are a standard feature for this window. The corners are closed which allows for full perimeter flashing. As an option, Gerkin can remove the nail fin for masonry or sub-frame installations.

Easy Tilt-in Sash

Easy Tilt-in Sash: The operating sash uses attractive flush mount tilt latches for easy cleaning.

Self-latching Lock at Sill

Self-latching Lock at Sill: For safety and convenience, the operating sash locks automatically at the sill when closed. The latches are concealed from plain sight and are easily activated by lifting up on the spring-loaded latches.

Sloped Sill

Sloped Sill: This feature eliminates the need for weeps under the sash. Air infiltration performance is enhanced due to this feature.

Smooth Block and Tackle Balance System

Smooth Block and Tackle Balance System: The block and tackle balance is one of the most reliable and long lasting balances available. This balance allows for an easy operation at all operating positions.

Mullion Interlock

Mullion Interlock: The use of a mullion interlock helps to reduce deflection and creates a snug fit. The structure of the window is enhanced and air infiltration is reduced.

Dual Weatherstripping

Dual Weatherstripping: This window features heavy wool pile weatherstripping with a Mylar fin on two locations of the sash. A bulb seal at the sill and interlock seals make this window one of the tightest single hungs available.

5/8" Double Strength Glass

5/8" Double Strength Glass: We insulate our own glass and offer a twenty year seal warranty as well as a one year stress crack warranty. With the use of the Super Spacer® warm edges spacer system, we ensurea long seal life and thermal efficient glass. Standard glass options are LoÉ3, bronze and gray tint, obscure, and tempered. Internal glass grilles are also a standard option. Special order glass options are available.

Extruded Aluminum Screen Frames

Extruded Aluminum Screen Frames: The strength of extruded screens is a major maintenance cost advantage for Gerkin over easily damaged roll form screens.

Standard Options: We offer complete sub-frame and panning systems, snap trims, sill flashing, stacking frames, stacking "H" channel, structural mulls, mull covers and factory applied extension jambs.

Other Options: We offer insulated panels as well as a louver system with a blank-off panel for PTAC units. This unit can be incorporated into our Rhino window system and used in conjunction with any Rhino window.
