Product Features

Authentic Timber Appearance

The R7 and R9 profiles are meticulously crafted to mimic the look of 19th-century timber windows, making them ideal for homes in conservation areas or those seeking to maintain a traditional aesthetic. The Halo flush sash range offers similar styling with the added benefits of modern uPVC, ensuring durability and ease of maintenance.

Energy Efficiency and Insulation

Our flush sash windows are designed to provide outstanding thermal performance. With multi-chambered frames and advanced double or triple-glazing options, these windows help to minimise heat loss, keeping your home warm in winter and cool in summer. This not only enhances your comfort but can also lead to reduced energy bills.

Security and Durability

Security is a key feature of our flush sash windows. Each window is fitted with high-security locking systems, providing robust protection against intruders. The durable uPVC construction ensures that these windows are resistant to warping, rotting, and fading, delivering long-lasting performance with minimal maintenance.

Have a question? Feel free to contact us.

In some cases, flush sash uPVC windows can be used in conservation areas or listed buildings. However, it is essential to consult with the local planning authority or conservation officer to understand the specific regulations and guidelines governing window replacements in your area. At Global Windows, we can assist you in getting the correct information and planning permission required.

The energy efficiency of sash windows depends on factors such as the quality of the materials used, the glazing, and the installation. Modern sash windows often feature double glazing, weatherstripping, and draft-proofing mechanisms, which improve their energy efficiency.

The cost of window installation varies depending on factors such as the number of windows being installed, the type and size of windows, the complexity of the project, and your location. For a free, no-obligation quote, contact us today.

Our flush sash windows are equipped with multi-point locking systems, offering high levels of security to keep your home safe.
