Facade structural engineering · Farmington, NY
Structural engineering for glass and aluminum building envelopes.
PER Engineering prepares sealed calculation packages for storefront, curtain wall, entrances, skylights and metal panel systems — engineered by people who have spent their careers building them.
Services
Structural and thermal engineering for the systems that close in a building — delivered as sealed, reviewer-ready calculation packages.
Storefront & curtain wall
Mullion, transom and anchor design; deflection and stress checks for stick and unitized systems.
ADM · ASCE 7Glass design
Load resistance and deflection for monolithic, laminated and insulating glass, including non-standard supports.
ASTM E1300Metal panel & rainscreen
ACM, insulated metal panel and ribbed siding attachment — fastener sizing, spacing and component & cladding pressures.
ASCE 7 C&CSkylights & entrances
Sloped glazing, perimeter gutters and support framing; entrance framing and hardware reinforcement.
ASTM E1300 · ADMRailings & attachments
Guards and handrails, sign and sunshade brackets, and anchorage to the facade or structure.
IBC · ADMThermal performance
Whole-system U-factor and condensation resistance modeling for fenestration and envelope details.
NFRC 100 · 200 · 500Design basis
Every package states its code basis up front, so the reviewer sees what governs before the first calculation.

Engineering from the glazing trade
PER Engineering was built inside the glazing industry. Our principal has worked in glass and aluminum since 1990 — fabrication, installation and design — so our calculations reflect how systems are actually built and installed in the field.
We work for glazing contractors, fabricators, system manufacturers and architects, and we write packages the way reviewers want to read them: clear basis, clear assumptions, clear results.
