Windows Series

Casement Window

The casement window is a timeless classic, revered for its ability to maximize ventilation and offer expansive, unobstructed views of the outdoors. At ALPES, our casement window systems are engineered for effortless operation, featuring smooth-turning cranks or push-out mechanisms that make opening and closing a breeze.

They are an ideal choice for rooms requiring excellent airflow and a strong connection to the exterior, bringing fresh air and natural light deep into your living spaces. The versatility of the casement design also allows for easy cleaning from the inside, adding to their practical appeal.

Sliding Window

Space-saving and sleek, our sliding window series is designed for areas where an outward or inward opening sash is impractical. These windows glide horizontally, making them a perfect fit for smaller rooms, kitchens, or any space where maximizing wall space is a priority. ALPES sliding windows are crafted with precision rollers, ensuring smooth, quiet operation for years to come. They offer excellent natural light ingress and broad views, creating a feeling of openness. Available in various configurations, including two-panel, three-panel, or even four-panel designs, our sliding windows combine practical functionality with a clean, modern aesthetic, enhancing both the look and utility of your environment.

Tilt And Turn Window

Representing the pinnacle of versatility and security, ALPES Tilt And Turn windows are an engineering marvel. With a single handle, these windows can either tilt inwards from the top for secure, draft-free ventilation, or swing inwards like a casement window for maximum airflow and easy exterior cleaning. This dual functionality makes them incredibly safe, versatile, and user-friendly. The tilt-in function allows for continuous ventilation even during rain, while the turn-in function offers an emergency exit option. Equipped with multi-point locking systems, our Tilt And Turn windows provide enhanced security and exceptional acoustic and thermal performance, making them a premium choice for modern, energy-efficient buildings.
