Buying Guide

Choose tempered glass

Tempered glass offers safer breakage behavior and greater impact resistance for garage and outbuilding windows

Match frame material to environment

Aluminum frames resist corrosion and are low-maintenance for garages exposed to humidity or chemicals

Consider mounting style

Flush-mounted panels suit tight exteriors while casement units provide outward ventilation and easier cleaning

Size for ventilation and light

Pick window dimensions that balance daylight with wall space — smaller 12x12 units for light, larger 14x21 or 18x23 for ventilation

Look for screens

Fiberglass or removable screens let you ventilate without letting insects into a workshop or garage
