uPVC Casement Windows

Designed to complement any home style, Koemmerling casement windows are one of the most popular uPVC window frames known for their clean design and practical functionality.

Sliding Windows
Koemmerling uPVC sliding windows are designed to cater to the modern architecture needs of both style and functionality. Sliding windows consist of two or more sashes that glide effortlessly on a horizontal track. The sashes are slightly raised above the track, ensuring smooth movement while preventing the dust buildup on the track. Koemmerling uPVC Sliding Windows are the space-saving windows, as they do not require clear floor space to open inward or outward. This makes them the ideal choice for compact areas like kitchens, balconies, corridors, and small utility rooms. Perfect as a uPVC window for balcony, they offer wider openings, abundant natural daylight, excellent ventilation, and an unobstructed view of the outdoors. Crafted with high-quality, premium-grade uPVC Koemmerling Sliding Windows offer maximum durability and weather resistance, unmatched energy efficiency, and low maintenance. Their structural strength can withstand any harsh weather condition of the Indian climate. With Koemmerling, every sliding window is not just a design feature but a smart investment in comfort, style, and lasting value.

Top Hung Windows
Top Hung windows are similar to classic casement windows but with one major difference—the hinges are mounted on top. Unlike casement windows, the hinges on top hung windows are mounted on the top, and the sash opens outward from the bottom, creating a practical and stylish ventilation solution. Koemmerling Top Hung uPVC Windows, with an upward-opening mechanism, are a smart and stylish choice for modern homes and commercial buildings, especially for spaces like kitchens and bathrooms, where optimum ventilation is required all the time.
