The performance of flush casement windows

A flush aluminium glass window is not only aesthetically pleasing, but it provides excellent energy efficiency and enhanced security.

Security Features

When it comes to security, aluminium is a preferred choice due to its strength. As part of our flush casement windows, Kesenbao incorporates a range of additional security features.

Glass Safety

We understand that safety is as important as being a sleek and stylish choice. With Kesenbao, each standard unit includes toughened safety glass that is not only very hard to break, but also provides maximum security.

Multi-point Locking

It is possible to lock a window in multiple places with a single key to prevent attacks with multi-point locks. All our windows are fitted with a multi-point locking system as standard, providing superior security for peace of mind and protection. New homes must comply with PAS 24 as standard for high security locks.

Aluminium – The Secure Choice

Kesenbao windows are made of top-quality aluminium. Low-density metals such as aluminium add strength and durability to a design without adding bulk. With aluminium’s robustness and high security hardware and locking mechanisms, the windows are completely secure.


Aluminium is an inherently robust material that offers strength and security as well as being extremely durable. Even the coating on our flush casement frames is resistant to corrosion and fading, so they will never need to be repainted or treated. Our windows are designed to last for years so you and your customers can rest easy.

Energy Efficiency

Building projects such as renovations, new builds, and commercial properties should consider the energy efficiency of windows.

At Kesenbao we make sure all our products, including our flush casement aluminium windows, meet and exceed Building Regulations. To this end, the standard glazing units used within our windows are designed to offer optimal thermal efficiency.

The U-Value is a measure of how well a building product insulates. In general, lower values indicate better insulation. You can achieve U-values as low as 1.5 W/m2K with a double glazed window with a thermally broken aluminium frame from Kesenbao.

Weather Performance

Our aluminium windows are rigorously tested to BRE Standards to ensure they remain weather-resistant.

According to the test results, our flush casement aluminium windows are airtight and water resistant, meeting and exceeding requirements. Additionally, the windows withstand repeated pressure cycles and wind loads.
