CORTIZO COR 70 HIDDEN SASH TB

The tilt and turn window are a modern window system that offers dual functionality: tilting inwards from the top for ventilation or swinging inward from the side for efficient cleaning and optimal airflow. This adaptable design provides both secure ventilation and easy access for cleaning, making it a highly favoured option in current construction. While initially prominent in European homes, these windows are now gaining popularity in the United Kingdom market.

The COR 70 Hidden sash windows are equipped with a hinge mechanism that enables them to open in two different ways. They can either tilt inwards for safe ventilation or swing inwards for effortless cleaning, making them a versatile option for various purposes.

Tilt Functionality: Ventilation and Rain Protection: When placed in the “tilt” position, these windows pivot at the bottom to open at the top. This design allows for ventilation without drafts and keeps rain out. It offers an ideal solution for maintaining a steady flow of fresh air.

Turn Functionality: Maximum Airflow and Easy Cleaning: When set to the “turn” position, aluminium tilt turn window function similarly to casement windows, opening to 90 degrees. However, they offer the added benefit of being able to swing open to 180 degrees, allowing for optimal air circulation and convenient cleaning access on both sides of the glass. Plus, in case of an emergency, these windows can also serve as a safe fire escape route, providing an extra level of security for your home.

Energy Efficiency and Performance: The Tilt turn window frames come in various options of glazing like double glazing, with a maximum thickness of 40 mm. These windows play a significant role in improving a building’s energy efficiency. The profiles are 1.9mm thick and can hold up to 160kg of glass. They provide exceptional insulation, ensuring warmth in the winter and coolness in the summer, consequently reducing energy bills. Additionally, incorporating polyamide strip lengths, like the 35mm found in the COR 70 Hidden Sash design, further enhances thermal performance. This results in an impressive transmittance Uw rating of just 1.0 W/m²K, reflecting their high level of energy efficiency.

Safety and Security: One remarkable feature of modern tilt and turn window aluminium is their outstanding safety and security measures. With a multi-point secure locking system and PAS24 accreditation, these windows guarantee protection against potential intruders when closed. Moreover, the availability of a tilt-only opening option adds an extra layer of safety for families with small children, as it restricts the window from being fully opened while still allowing proper air circulation.

The COR 70 Hidden Sash TB offers a unique feature – the ability to include windows with built-in blinds. These blinds for tilt and turn windows are especially well-suited for Flush windows, and offer a simple, seamless way to achieve a sleek appearance. They come in manual, solar, battery-powered, and mains powered options, making them versatile for privacy screening and light control purposes.

This feature is also present in our COR 70 Tilt and Turn Windows, allowing for the integration of an arch invisible handle and concealed hinges. These components are carefully crafted to blend seamlessly with the window’s sleek design, avoiding any unnecessary distractions.

Multi Point Locking System:  The Tilt turn window system boasts a robust multi-point locking mechanism, ensuring enhanced security by firmly securing the window at multiple points along the frame. This essential feature offers peace of mind and serves as a strong deterrent against forced entry.

From residential properties like balconies, extensions, and conservatories to commercial buildings seeking contemporary turn window options, these windows are a great fit.

Such high-quality methods guarantee not only lasting versatility and functionality in design, but also an attractive aesthetic appeal for the windows coated in any RAL color.

Using a tilt and turn window is a simple way to have various ventilation choices. Keep in mind the importance of handling the window gently and always make safety a priority when using them by following these essential guidelines:

Closing and Opening: To operate the window, adjust the handle into either a vertical or downward position. Then, with a strong push, close and secure the window. To open it, simply turn the handle sideways or horizontally.

Tilt Window Function: To effectively ventilate the room while ensuring safety, just rotate the handle horizontally. This will tilt the top of the window inward, providing a slight opening for airflow without completely opening it.

Turn Window Function: To improve air flow and facilitate cleaning, simply rotate the handle to a vertical position. This will allow the window to open inward, functioning like a door and granting complete access to the room’s interior for easy cleaning.

It is crucial to refer to the manufacturer’s instructions, as the operating mechanism may differ.
