Our ALU5 windows are double glazed as standard. This ensures that these windows have U-values as low as 1.3Wm2k. With a strong focus on energy efficiency, our triple gasket system creates an airtight barrier. This will reduce cold draughts. Our double glazed aluminium windows are constructed with insulation to improve soundproofing. This can improve sleep cycles and increase overall quality of life.

Features & Benefits
We offer a variety of finishes for our ALU5 windows. You will be able to choose from a range of internal and external finishes to design your windows to perfectly match your project.
Our ALU5 windows require minimal maintenance and have a long lifespan. This means that you can rest assured that your windows will stay looking as good as they do at installation.
Our ALU5 windows are completely compliant with the PAS 24 2016 security test. This means that our aluminium windows meet enhanced security performance requirements.
Hardware & Glass Options
The Visiline ALU5 windows have a variety of hardware and glass options to customise your windows based on whether you want to improve the thermal efficiency, light emission, or sound reduction of your home.
Choosing the right glass options for your home is important. Our options include the LowE clear glass, which maximises the supply of natural light to improve light transmission in your home, and the Super LowE, which boasts low emissivity, reducing heat loss.
A premium option is the Planistar® Sun glass, an all-around pleaser with low emissivity and high energy efficiency. With this option, your windows reduce your home from overheating in the summer and increase thermal insulation in the winter.
Safety glass is an option worth considering too. A durable thick glass pane is created by glueing two panes of glass together with transparent resin, increasing safety by reducing the risk of accidents. If the glass breaks, it will not shatter.
To increase the privacy of your ecoHaus windows, a great solution is choosing ornamental glass. You can choose from satin glass or more textured glass, and tinted options are available too. These windows provide more privacy without compromising on light transmission.
Another way to customise your windows is with the handles. We have more sleek handles, like the minimalistic designs, and more secure ones, where you can add a key for added security. We also offer “invisible” handles which are embedded in the side of the frame, giving a minimalist look to the whole system.
All ecoHaus handles are available in silver, white, black, or anthracite grey. The Brest Secustik matte titanium handles are available in bronze, white, and black but are an exclusive option for a limited range of windows. Call us on 0800 612 6519 to see if your windows are one.
Our ALU5 windows are compatible with a wide array of hardware and additional furniture. From handles in a host of colour finishes, to the most secure locking systems, our Visiline windows are fitted with the very best.
