Thermal Frame Window-Wall Series 4800-T

Design Notables

Visual Continuity:

The Series 4800-T was designed to provide large glass facades while pairing well with the Series 3800-T (4 ½” frame). Both the 4800-T and 3800-T have a 1-7/16” perimeter frame and 2-7/16” TDL, allowing for consistent lines across your elevation as you blend product types as appropriate for their respective openings.

Inside Glaze Option:

The Series 4800-T can be fabricated with the shelf to the interior or exterior.

Concealed Water Evacuation:

The horizontal TDLs are designed to direct water through the system with no exposed weep slots. All water is directed to the bottom sill, which contains a few low profile weep slots.

Strength & Sizes

Large Sizes:

How big do you need? The Series 4800-T can handle enormous spans without structure or inserts. This is accomplished with our patent pending Glass Anchor (GAC) that bolsters each suspended vertical and horizontal.

Dead Load & Shear Stress:

Support plates are provided with every intersecting TDL to support the glass weight as well as provide additional bolstering for wind loads. Each support plate is constructed from 400 series stainless steel.

Energy & Glass

Custom Strut:

Each Series 4800-T is made with a custom designed thermal strut. Fleetwood designed the strut to allow the Engineering Department to fulfill the high expectation design notables.

U-Factor Performance:
The energy test results of the Series 4800-T are outstanding because of the minimal frame, specialized engineering, and custom thermal strut. For example, with low emissivity glass, the Series 4800-T achieves a 0.25 U-Factor.

Numerous Glazing Options:
The Series 4800-T offers more glass choices than any other aluminum fixed window in the luxury home market. This is possible with the number glass depth choices and the myriad of glass offered in the industry.

Massive Glass:
Insulated glass larger than 100 square feet is available in the Series 4800-T.

Smart Design – Installation

Factory Engineered – Field Assembled:

The patent pending Glass Anchor (GAC) was designed out of aluminum to withstand highly corrosive environments. Its unique design allows for field assembly that does NOT require a licensed specialist.

Gorgeous Finish:
Each TDL is equipped with a Glass Anchor Cover (GAC) that can be installed at the project’s completion so the aluminum finish is not damaged during construction.

Nail-On Slim Perimeter Frame:

The head, sill, and jambs ONLY reveal a 1-7/16” sightline and clever building design can hide even more. The integral nail fin offers peace of mind during waterproofing.

Outstanding Details

Hidden Weep Slots:

Most window-walls include obvious drainage holes/slots in the horizontal frame members. The Series 4800-T was engineered with visible weep slots only in the sill.

Operable Inserts:

Series 450-T casement and awning windows can be inserted into any opening created within a Series 4800-T system.

Product Marriage:

The 5 ¾” frame depth was chosen to allow installers to abut the Series 4800-T to a 2-track Series 4070-T, 3-track Series 3070 and 3-track Series 3070-T.

Fewer Distractions:

The vertical and horizontal TDL shapes in most residential windows have numerous seams where the glass is pinned into place. Minimalists will appreciate the one-piece Glass Anchor Cover (GAC) that is unique to the Series 4800-T.
