The origin of narrow-framed doors and Windows
Derived from the top-level mansion standards of Europe in the 1990s,
through precise calculation and innovative design, while ensuring structural safety,
this product has achieved the ultimate refinement of the frame.
Our narrow frame design is not only an aesthetic pursuit,
but also a rethinking of the relationship between space and light.
About SLEEK
SLEEK has been focusing on the research and development and production of narrow frame system doors and windows, providing customers and designers with a variety of door and window solutions with minimalist visual effects. We hope to bring more light into the interior of the building and create a natural connection with the outdoor landscape.
