Industry Insights

Fall Protection:

Fall protection was established by OSHA to provide a safe and healthful working environment and to limit falls from workers or tools from heights of 6’ or greater. OSHA regulations state that every skylight must be guarded by a standard skylight screen or fixed railing system that is capable of withstanding a load of at least 200 pounds.

Code Requirements: (per IECC 2015 - Climate Zones 5 & 6)

U-Factors of fenestration systems (e.g., skylights) shall be determined by an accredited, independant laboratory in accordance with either NFRC 100 or ANSI/DASMA 105 AND labeled by the manufacturer.  Products lacking a U-Factor label shall be assigned a default U-Factor per IECC 2015 Tables C303.1.3(1)-(3).

The prescriptive performance requirements (i.e., U-Factor & SHGC) for skylight systems are indicated in Table C402.4 of the IECC 2015. 

Prescriptive compliance is only allowed with a skylight area less than or equal to 3% of the gross roof area.  Prescriptive compliance is allowed up to not more than 5% of the gross roof area if certain minimum floor areas are in the daylight zone and daylight responsive controls are incorporated.

Skylight U-Factor & Solar Heat Gain Coefficient (SHGC) may be be permitted to increase to 0.75 & 0.60 respectively if skylights are installed above dalight zones provided with daylight responsive controls.

Skylights may be required for enclosed large volume spaces (i.e., >2500sf & >15' ceiling height) to provide a daylight zone of not less than half of the total floor area of the space.  Note the threshold for a large volume space in the IECC 2015 has significanly decreased from the threshold of >10,000sf & >15' ceiling height from the IECC 2012 and previous versions. 

The air leakage of skylight assemblies with condensation weepage openings shall be a maximum of 0.30 CFM/FT2 per AAMA/WDMA/CSA101/I.S.2/A440 or NFRC 400.  All other skylights shall have a maximum air leakage of 0.20 CFM/FT2.
