Hardware & Glass Options

Your Visiline ALU6 Windows can be tailored for your home to improve the thermal efficiency, privacy, or security of your home. ecoHaus offer a range of customisations to help you create bespoke windows for your home.

The Planistar® Sun glass is a great all-around pleaser with low emissivity and high energy efficiency which help increase the thermal efficiency of your home. This means reducing heat escaping in the winter and preventing your home from overheating in the summer.

We also offer a Safe Glass option which comprises of two panes of glass, glued together with transparent resin to increase its durability. This type of glass does not allow the detachment of shards in case of breakage.

A way to increase privacy without compromising light transmission is by opting for one of our ornamental glass options. We offer satin glass and textured glass, as well as tinted glass options being available, that provides you with more privacy and optimal light.

ecoHaus offers Warm Edge technology that can increase the thermal performance of any windows. By assembling a thermoplastic sealant around the perimeter of the window, it helps retain the heat within your home. Additionally, it has a lower linear thermal conductivity than the conventional aluminium spacer.

Another customisable feature of our windows are the handle options. We offer the option to have keys built into the handles if you wish to heighten the security levels of your windows. There are also more sleek designs available, including an “invisible” handle, embedded within the frame.

All of the handles we offer come in either silver, white, black, or anthracite grey. We also have available an exclusive handle made of matte titanium and available in bronze, white, and black. Call us on 0800 612 6519 to see if it is available with your windows.
