Self-Supporting & Supported Ridge - Insulated Skyroof Systems

Light-years Ahead: KALWALL SKYLIGHTS & SKYROOFS ^™

A comprehensive line of standardized prefabricated and pre-engineered skylights and skyroofs fit perfectly into many designs. Custom engineering offers limitless possibilities including hurricane resistant, FM Class 1 and UL Class A Systems. See Kalwall's downloadable Sweets Product Catalog (08 45 23/KAL – previously 08950/KAL) for more information.

Kalwall Insulated Skyroof Systems

Most custom Skyroofs are either shed or supported ridge type, designed to be installed over required substructure by "others". However, self-supporting ridgetype skyroofs in four standard slopes, spanning over 20 feet without exposed substructure, are common.

Caution: Details for self-supporting Skyroofs are different! See below.

JOINT SYSTEMS - see Plans A & B below

Kalwall Skyroof Systems allow flexibility in design by a choice of two distinct panel-to-panel joint systems: the 2" (51 mm) or 2-1/2" (64 mm) Double T; and, the Overlap*. As shown in Plan A, when the supporting substructure runs across the slope, panels will be installed with the slope and joined with a Clamp-tite Double T batten, Section 4. When the substructure runs with the slope, the Overlap joint system, shown in Plan B and Section 2, is used.

PERIMETER DETAILS

Except for canopy applications, Kalwall strongly suggests use of the curb-type perimeter system, keeping the Skyroof above the roof plane and providing a natural expansion joint. The Clamp-tite perimeter frame, factory-sealed to the Kalwall panel for standard systems, can be either Section 3A; or for wider curbs (or Thermal Break) Section 3B. Section 3B provides the most rough opening “forgiveness” but may limit clear span and/or live load capability. PLEASE, check with us for detail assistance early in your design stage.

RIDGE DETAIL

Section 5 shows the supported ridge connections. Note that the supporting ridge members should be at least 7" (178 mm) in width. A thermally broken option is available.

VERTICAL WALL DETAIL

A half ridge section is used, as in Section 1, with counter flashing by others back to the adjoining wall surface.

SUPPORT

Standard Kalwall Skyroof Systems must be supported as required by local codes. See Kalwall’s Span Guide below (generally 10' under a 30 lbs./sq.ft. live load (1450 Pa). The Skyroof System will be fastened to the support as indicated in Section 4.

Kalwall can provide greater clear span capability, as indicated in Section 6, utilizing the 3-1/4" (83 mm) Integral Stiffener.
