V60 Curtain Wall System - the Nelson-Atkins Museum - Steven Holl

Benefits / Characteristics:

- Double-glazed, thermally broken, double-seal open wept system enhances thermal performance & effectively controls water drainage
- Thermally enhanced SF-60 channel glass walls can achieve U-value of 0.19 or lower
- SF-60 seamlessly integrates flat glass IGUs, providing continuous design lines
- Unique frame design requires the glass be captured at the head & sill only
- All components (head, sill, jambs) are visually identical for consistent, clean look
- Accommodates vertical or horizontal glass channel orientation, including a unique unitized horizontal configuration
- Accommodates all channel glass textures (60 mm flanges)
- Multiple frame configurations, including all-glass curves (min. radius = 7 ft. (2 m)) & corners
- Standard finish is 2-coat Kynar Arcadia Silver; custom colors available
- Supported by industry-leading technical design team
- Made in USA

Okapane Channel Glass Insulation:

Benefits / Characteristics:

Excellent thermal insulation for double-glazed channel glass walls
Can achieve glass wall U-value of 0.19 (combined with Low-E coating)
Visible Light Transmission (VLT) of approx. 40%
Lightweight
Evenly scatters and diffuses light, minimizes glare
Excellent sun shading effect
Impervious to moisture
Smooth, homogeneous appearance

Details:

Composition:

Miniature acrylic tubes covered by translucent fiberglass sheeting

Applications:

Interior, Exterior

Installation:

Inserts in the cavity of a double-glazed channel glass wall. It is secured with silicone at the top, bottom, and one continuous side. The material arrives cut-to-size from the factory, and can be easily re-cut in the field to meet job conditions.

Approximate Dimensions:

Factory cut-to-size; Thicknesses = 5/8” (16 mm), 1′′ (24 mm), 1.25′′ (32 mm), 1.5′′ (40 mm); can be easily cut to size in the field to meet site conditions

Approximate Weight:

0.25 lbs/ft2 (1.2 kg/m2)

Maintenance:

Okapane insulation is securely inserted and sealed inside the cavity of a double-glazed channel glass wall, and does not require maintenance post installation.

Performance Characteristics:
Visible Light Transmittance (VLT) = 38% (24 mm Okapane)

U-Value = 0.28 (24 mm Okapane without Low-E) / 0.19 (24 mm Okapane with Low-E)

Solar Heat Gain Coefficient (SHGC) = 0.38

STC Rating = Brings an improvement of 1-2 dB soundproofing

Lightweight
Evenly scatters and diffuses light, minimizes glare
Excellent sun shading effect
Impervious to moisture
UV-stable, temperature-stable up to 212°F (100 ° C)
Self-extinguishing

Details:

Composition:
Glass fibers coated with a UV-stable binding agent
Applications:
Interior, Exterior
Installation:
Inserts in the cavity of a double-glazed channel glass wall. It is hung with factory-installed hook strip, silicone at the top, and continuous transparent tape on one side. The material arrives cut-to-size from the factory, and can be easily re-cut in the field to meet job conditions.
Approximate Dimensions:
Factory cut-to-size, compressible; Thicknesses = 2.75” (70 mm – GL), 4” (100 mm – GL Plus); can be easily cut to size in the field to meet site conditions
Approximate Weight:
0.25 lbs/ft2 (1.25 kg/m2)
Maintenance:
Wacotech TIMax insulation is securely inserted and sealed inside the cavity of a double-glazed channel glass wall, and does not require maintenance post installation.
Performance Characteristics:
Visible Light Transmittance (VLT) = 48% (GL) / 23% (GL-Plus) U-Value = 0.24 (GL) / 0.19 (GL with Low-E) / 0.19 (GL-Plus) Solar Heat Gain Coefficient (SHGC) = 0.43 (GL) / 0.24 (GL-Plus) STC Rating = Brings an improvement of 1-2 dB soundproofing
Testing:
