What thermal expansion and deformation analysis reports must be included for aluminum curtain wall frames?

Thermal movement documentation is essential to prevent stresses, buckling, and failure at interfaces. Provide: (a) Coefficient of thermal expansion (CTE) data for alloys and anodized/coated finishes and expected dimensional change per temperature range; (b) 2D/3D thermal expansion simulations showing movement allowances at mullion-to-slab and panel joints using THERM or equivalent tools; (c) Detailing for thermal break design and how it mitigates heat flow and movement; (d) Stress calculations for fasteners and connectors over expected temperature cycles including peak summer/winter extremes; (e) Gap, slot, and slide connection specifications with recommended tolerances and back-up sealant requirements; (f) Guidance for joint design to accommodate differential movement with movement diagrams and field adjustment procedures; (g) Laboratory verification of long-term creep or relaxation under sustained temperatures where insulation or adhesives are used; (h) Installation tolerances and mock-up requirement to verify that designed tracks and expansion features function as intended. Provide simulation input files and stamped calculations so structural and façade engineers can confirm compliance with thermal movement criteria.
