Daylighting with Control
Skylights and roof windows transform low-slope attics, but they must be sized and oriented thoughtfully. Target 3–5% of floor area as daylighting in bedrooms and 5–10% in studios. Favor north/east orientations for soft light; pair south/west glazing with lower SHGC glass and interior shades.
Thermal & Glare Management
Specify low-U, low-SHGC, argon-filled, laminated glass. Add blackout or light-filtering shades (manual or motorized) and consider exterior awnings where solar exposure is intense. Use matte, light-reflective finishes on slopes to bounce daylight deeper without hotspots.
Leak-Proof Detailing
Use manufacturer pan flashing kits, integrate self-adhered membranes, and insulate/air-seal the skylight shaft to prevent condensation. Maintain roof underlayment continuity and verify slope requirements per the cut sheet. Schedule a flood-hose test after installation and before finishes.
Code & Egress
If a skylight doubles as an emergency escape/rescue opening, confirm net clear opening and sill height. In landmark districts, exterior profiles may need review.
