Patio Doors
by A1 Windows
A well-designed patio door makes the boundary between your home and outdoor living space disappear. Maximum glass, wide clearance, and a seal that holds through Georgia's summers and storms.
What Makes a Great Patio Door?
A patio door is a hinged door — or pair of doors — with large glass panels designed to connect your interior living space directly to a deck, patio, or backyard. Unlike a sliding door that glides on a track, a hinged patio door swings fully open, giving you an unobstructed passage with no threshold to step over.
The glass area is maximized to flood your interior with natural light and frame your outdoor view. A well-installed patio door with Low-E glass does this without the heat gain penalty — keeping your air-conditioned interior cool even when Georgia's sun is hammering the glass all afternoon.
Benefits of Hinged Patio Doors
More light, more clearance, and a better connection between your home and outdoor living space.
Maximum Natural Light
Large glass panels bring in significantly more light than a standard door. Rooms that adjoin a patio feel brighter and larger — without adding a single square foot.
Wide, Clear Opening
Hinged patio doors swing fully open — no track along the floor, no reduced clearance. Ideal for moving furniture, entertaining, or accessibility.
Energy-Efficient Glass
Low-E dual-pane glass reflects solar heat away in summer and keeps warmth inside in winter. ENERGY STAR certified for Georgia's Southern climate zone.
Solid Security
Multi-point locking hardware engages the frame at multiple locations. Reinforced strike plates and heavy-duty hinges make hinged patio doors significantly more secure than older track-based doors.
Built for Georgia Homes
A patio door with a large glass area is a significant energy asset — or liability — depending on how well it's built. In Georgia's climate, the details matter.
Low Solar Heat Gain
Low-E glass with a low SHGC (Solar Heat Gain Coefficient) blocks the radiant heat that pours through west- and south-facing patio doors in a Georgia afternoon — without dimming the view.
Weatherseal That Lasts
Compression weatherstripping around the full door perimeter maintains its seal through Georgia's humidity cycles and temperature swings — no annual re-caulking needed.
Screen Systems
Full-length screen options let you leave the door open for a breeze without inviting Georgia's insect population inside — essential from April through October.
