Pyramid and Geo-Roof® Standard Skylights
INSULATION
“U” = .29 standard. Options .53, .22, .18 and .05; or Thermally Broken
.23, .14, .10 and .05.
PANEL THICKNESS
2-3/4" only.
LIGHT TRANSMISSION
Any interior/exterior combination of exclusive super weathering translucent faces
with erosion barrier resulting in light transmission range of 14% to 60%. Options
from 3% to 74% in other colors. See Kalwall brochure, 08950/KAL, for full explanation.
GRID PATTERN
Geo-grid standard for Geo-Roof. Shoji pattern Pyramids, custom grids optional.
EXPOSED ALUMINUM FINISH
Standard is mill finish. Optional Kalwall corrosion-resistant finish in a variety
of colors.
COLOR INSERTS
Color inserts are optional and available in a wide range of colors.
DESIGN LOAD
All standard Geo-Roofs and Pyramids designed for 40 lbs./sq.ft. live load, except
for 27' and 28' Geo-Roofs. Higher loads may require a different design.
FACTORY PRE-ASSEMBLY
Units up to 8' nominal pre-assembled into one piece. Geo-Roofs over 8' to 16'
overall outside dimensions shipped in halves. Larger roofs shipped in segments.
Pyramids shipped knock-down in 4 sections for 9' to 12' and 8 sections for 13'
to 20'.
Pyramid Engineering Data
Design
Factory pre-engineered components for standard sizes from 4' to 20' in one-foot
increments… rapidly installed. All energy-efficient, as well as aesthetic, options
are available.
Construction
Designed for installation over the Kalwall-supplied curb cap extrusion. The pre-engineered
panels, joint system and, in larger size, exposed box beams fit together precisely
to form a highly dependable, weathertight structure.
All Standard Pyramids Designed For Installation From The Outside.

Geo-Roof Engineering Data
Design
Prefab elements in sizes from 8' to 28' provide a new concept to highlight any
overall design… easily engineered into any construction. Optional colored inserts
are available for added interest. Optional colored finishes are also available
on exposed aluminum.
Construction
Clean design for thrust-bearing curb mounting and watertight seal. Light weight
simplifies installation. Factory assembled elements easily installed on site;
only two joints and perimeter to seal on units 9' and 16' diameter — complete
factory assembly for 8' units.
Most Geo-Roofs Require Both Inside and Outside Access for
Installation

There are no other skylights as insulating as Kalwall’s
PROVEN GEO-ROOF® and PYRAMID Series!
SPECIAL SIZES AND DESIGN For Curved Domes… call for details!
- Larger spans approaching 100' Clearspan are available with the combination
of Kalwall over an aluminum box beam support structure.
- Special shapes and slopes are also possible. Complete Kalwall/Structures
Unlimited buildings are also available. Contact Kalwall for assistance on any
project you may have in mind.
- Standard flat skylights from 2' x 2' to 5' x 20' ready for curb mounting.
Kalwall is a composite sandwich; various combinations are possible and test data should be interpreted from this point of view. Consult Sales Service Department for further clarification.
Since this table is of a very technical nature, please consult your heating and ventilation engineer for proper interpretation.
Note .23, .14, .10 and .05 U-values indicate thermally broken panels.

“U” value SI conversion: 1.0 w/m2k = 0.176 BTU/(hr•ft2•°F)
- Approximate values by ASTM E-972. Light transmission values over 30% not recommended for most appications.
- “U” values determined by NFRC test method (ASTM C-236, E-1423 and C-1199 at certified lab). Expressed as
BTU/(hr•ft2•°F) for aluminum grid / thermally broken grid, nominal 12" x 24" (300 mm x 600 mm). Perimeter aluminum
excluded. Test temperature at 15 mph wind (6.7 m/s): 0°F (-18°C) cold side & 70°F (21°C) warm side.
- Shading Coefficient (SC) is equal to 1.15 tmes the Solar Heat Gain Coefficient (SHGC).
