FINEO is a vacuum-insulating glass which we use for double glazing retrofitting projects. It consisting of 2 panes of glass separated by a vacuum gap.

Perfect Glass for listed buildings, conservation properties & window refurbishment projects

Fineo is a market leader when it comes to upgrading windows from single to double glazing. It’s the perfect option in Grade II listed buildings or in homes where owners would like to keep old window frames in place to retain the charm of their house. With many benefits, Fineo has not only become the chosen product for homeowners, but it’s easily the top-recommended product here at Chameleon. Let’s take a closer look at the product, it’s benefits and how it compares to other double glazing units.

1. Fineo glass does not require an evacuation port and
2. does not contain any inert gases.
3. Fineo comes with a 15 years guarantee.

What is Fineo glass?

Fineo is quite simply the latest generation of vacuum-insulated glazing options. With the same thermal value as triple glazing, but without exceeding 6.7mm, these units are incredibly lightweight and discreet. Never changing the look of your windows, it’s the perfect solution for the refurbishment of sash windows that might not be able to support the weight of regular double or triple glazing, or a perfect option when considering glazing units in a new build.

How does Fineo glass compare to other glazing?

With superior glass technology, Fineo removed the air between the glass panes to create a vacuum instead of filling the space with gas as is tradition in double glazing.

Although this vacuum does the same job as the gas by keeping the heat inside your home, it can not evaporate and totally disappear after about five years as gas normally does. This is what makes Fineo a more reliable option and a long-term investment when it comes to retrofitting your windows.

It makes your home brighter

By letting in 15% more natural light into your home, Fineo brightens up rooms in your home to allow you and your plants to thrive. However, light isn’t the only thing it lets in; as an added bonus, you’ll find the sun penetrating your rooms, which should, again, help with reducing your energy consumption. 

Improved noise reduction

An especially useful feature if you’re in an area with traffic or a higher footfall. With Fineo you can shut out most of your neighbourhood noise as these units outperform most other insulated glass options by reducing noise anywhere up to 12db.
