Typical patio doors rely on lightweight seals and hardware that wears down over time, leading to drafts, noise, and sticking tracks. KleerTek’s sliding door systems solve these issues with engineering that feels as solid as it looks.
Manufactured in our innovative facility in North Carolina, our sliding doors are designed with exceptionally strong frames and tight seals. From high-end residential projects to commercial buildings, these doors are built for larger openings, seamless transitions, and exceptional thermal performance.
KleerTek offers two advanced sliding systems:
Smoovio Door – A gliding, airtight system that moves effortlessly with a gentle push.
Lift-and-Slide Door – A premium design where panels lift slightly before sliding, creating a perfect weather-tight seal when closed.

KleerTek sliding doors bring elegance, performance, and comfort to every home.
Whether you’re upgrading an older patio door or designing a new space, our systems deliver the strength and insulation of European design with American manufacturing. Get in touch to learn more.
Our German-engineered hardware allows massive glass panels to glide open with one hand. Each door lifts smoothly from its seals when opened and locks down tightly for an airtight close.
Unlike patio doors that rely on leaky brush seals, KleerTek uses bulb-seal technology for exceptional wind, rain, and air resistance and long-term durability.
With multi-chambered uPVC frames and steel reinforcement, KleerTek doors minimize heat transfer and air leakage, helping you maintain steady indoor comfort and reduce energy costs year-round.
Our structural strength allows for doors up to 21 feet wide and 9 feet tall, creating floor-to-ceiling glass walls that flood your living space with natural light.
KleerTek’s sliding doors use tight-seal technology instead of brush seals, ensuring better air tightness, weather resistance, and long-term performance.

Our doors can reach up to 21 feet wide and 9 feet tall, with configurations available for two, three, or four panels.
Smoovio doors release their seal by moving slightly sideways when opened. Lift-and-Slide doors slightly elevate slightly before sliding. Lift and Slide allows larger total frame openings than Smoovio. Both utilize a tight seal and smooth operation.
