High-Altitude Engineering
High ground snow load, hard freeze-thaw, and high-altitude UV that ages sealants and gaskets faster than the same products age at sea level. Valley winds funnel along the corridor, which is precisely why glass wind screens are a signature local product: they cut the wind on a terrace without touching the view of Bald Mountain.
Recommended Systems for Sun Valley
Mountain installations face elevated UV intensity (25-40% higher than sea level), extreme temperature swings, heavy snow loads, and in some locations seismic activity. INFINITYGLASS alpine specifications include UV-stabilized sealants, freeze-resistant anchoring, and snow-shedding base shoe designs that prevent ice accumulation.

Building Codes & Regulations
Sun Valley permits through the City of Sun Valley as its own jurisdiction within Blaine County, under the Idaho Building Code as adopted by the Idaho Building Code Board, currently the 2018 International Building Code with Idaho amendments, referencing ASCE 7-16 for loads. The number that changes the engineering here is snow: Blaine County and its cities publish local snow-load design criteria that supersede general state values, and mountain-valley figures run several times what a lowland market designs to. A guard or wind screen below a roof edge or on a deck that receives shed and drifted snow carries a surcharge a catalogue product was never rated for. Guards follow IBC Section 1015 at 42 inches minimum, with guard glazing per IBC Section 2407 meeting CPSC 16 CFR Part 1201 Category II or ANSI Z97.1 Class A. Sun Valley and Ketchum are separate permitting authorities with their own amendments; confirm the correct city before submittal.
INFINITYGLASS™ provides PE-stamped engineering drawings for permit submittal in Sun Valley and all Idaho jurisdictions.
Frequently Asked Questions: Glass Fencing in Sun Valley
What building code applies to glass railings in Sun Valley?
The Idaho Building Code, currently the 2018 IBC with Idaho amendments, administered by the City of Sun Valley as its own jurisdiction. Sun Valley and Ketchum permit separately.
Why do snow loads dominate railing design here?
Blaine County publishes local snow-load criteria that supersede state values, and decks and terraces receive shed and drifted snow. Guards and wind screens are engineered for that surcharge, not just wind and occupant loads.
How tall must a glass guard be in Sun Valley?
At least 42 inches from the walking surface per IBC Section 1015 for most occupancies.
What glass is required in a guard?
Laminated glass constructed of fully tempered or heat-strengthened glass meeting IBC Section 2407 and either CPSC 16 CFR Part 1201 Category II or ANSI Z97.1 Class A.
Do glass wind screens work on mountain terraces?
Yes, they are one of the most common local applications: they block valley winds and extend the outdoor season while preserving the mountain view. They are engineered to the same load cases as guards when they protect an edge.
Do you provide stamped engineering for Blaine County permits?
Yes. Project-specific PE-stamped calculations are prepared to the local snow-load criteria and the applicable IBC load cases.
