Your patio door connects your home to the outdoors. Unfortunately, traditional wood patio door frames can rot, crack, warp, and require regular painting to keep them looking their best.
FrontLine patio door frames are engineered with durable aluminum cladding that protects the frame from moisture, sun exposure, and harsh weather—so you can spend less time maintaining your home and more time enjoying it. FrontLine’s aluminum-clad systems are designed to be low-maintenance, weather-resistant, and built for long-term performance.
Patio doors get blasted by the sun. Armed with premium AAMA commercial-grade finishes, our patio cladding actively resists the forces of nature™, defying UV fading, peeling, and chalking for decades, meaning “no more painting”.
Your patio or deck is where you relax and entertain—you shouldn’t have to stare at an ugly installation. Traditional methods use visible face-nails. Frontline’s patented interlocking system utilizes entirely concealed fasteners, giving you a smooth, clean frame that elevates your outdoor living area.
Because they often sit flush with decks and patios, water often pools at the base, leading to hidden subfloor rot. Our impermeable aluminum doesn’t wick water, preventing the ‘hidden rot’ that destroys wood frames from the ground up.
A beautiful patio door can quickly lose its appeal when the frame begins showing signs of weather damage.
Traditional wood frames are constantly exposed to rain, snow, humidity, UV rays, and temperature swings. Over time, this can lead to:
FrontLine’s aluminum cladding acts as a protective shield around the frame, helping prevent moisture intrusion and eliminating the need for ongoing painting and maintenance.
