Two Opening Options. One Game-Changing Product.

The versatility of the Deceuninck tilt and turn system lies in its dual-action design:

Tilt Mode – Safe, Secure Ventilation

Let in fresh air without compromising security. The top-tilt position delivers controlled airflow, ideal for family homes, ground-floor rooms and apartments where safety matters. Enjoy day-to-day ventilation with complete peace of mind.

Turn Mode – Effortless Cleaning & Maximum Accessibility

The inward-opening turn function gives you full access to the exterior pane, making cleaning quick, safe and stress-free. For multi-storey homes and high-rise developments, this feature is not just convenient, it’s essential.

This combination of practicality and ease of use makes tilt-and-turn windows a smart upgrade for any property.

Outstanding Energy Efficiency That Pays You Back

Looking for energy-efficient windows that truly deliver? Deceuninck tilt-and-turn windows are engineered with advanced multi-chambered profiles designed to maximise thermal efficiency. Every component works together to reduce heat loss, eliminate draughts and improve indoor comfort.

The inward-opening system compresses the window seals more effectively than standard casements—giving you superior insulation and acoustic performance. When paired with high-performance glazing, the result is a warmer, quieter, more efficient home and lower ongoing energy costs.

These windows outperform many aluminium windows in thermal performance, providing a warmer frame without sacrificing strength or aesthetics.

Built Strong for Long-Term Reliability

Deceuninck’s reputation for durability is shown in every detail. Premium PVC-U profiles, reinforced frames and robust 3D hinges ensure smooth, dependable operation for years to come. Designed to handle large sash sizes without compromising stability, this system is perfect for modern architecture and wide openings.

The product is also internally glazed, adding another layer of security while streamlining installation and achieving a clean, refined finish inside the home.

Security You Can Trust

Your home deserves protection. That’s why these tilt and turn windows include:

• High-security multi-point locking
• Steel-reinforced frames
• Internal glazing beads for anti-tamper protection

Even with the window in tilt mode, your property remains secure. The system is fully PAS 24 compliant, meeting the most demanding security standards for residential and commercial applications.

A Colour Range That Sets You Apart

Whether you prefer bold architectural statements or subtle contemporary shades, Deceuninck offers one of the industry’s most impressive colour collections. Choose from more than 30 stocked finishes, including heritage tones, modern greys and realistic timber-look foils. For bespoke designs, extended options and full RAL colours are also available.
