Insulating window film

Installing Umisol® window film greatly improves the thermal insulation of your existing glazing during the winter. The heat generated by your heating system is reflected back into the room, so the warmth that would normally be lost through the glass remains in the house. This results in savings on heating costs of up to 30%, depending on the kind of glass. The investment is recovered very quickly in just a few years.

The energy savings you make during the entire year are not only good for your budget but also for the environment because CO2 emissions are reduced. 

Your existing glazing gains in value without you having to pay for new windows and special cutting and breaking.  Create a perfect climate with pleasant warmth in winter and refreshing coolness in summer. 

Umisol Group NV undertakes to provide high-end, quality window film.
We offer a manufacturer’s guarantee of 10 years on our Umisol® window films.
The life of the foils is actually much longer. You can be sure that Umisol® foils will retain their visual clarity and quality properties.

Mansion in Brussels

The front face of this lovely mansion is completely south-facing. The installation of blinds didn't resist the heat from the sun radiating in. On the contrary, they generated local heating which resulted in convection-heating. The blinds also darkened the residence. The installation of Umisol® brought a solution for the high internal temperature without darkening the windows. The practically invisible glass foil stopped the troublesome heat, whilst at the same time retaining the optical transparency.

Notary office in Gent

This beautiful notary residence at the Lousbergkaai in Gent was completely covered with Umisol® glass foil. The thermal discomfort mainly occurred in the office sections. The French windows have clear glazing with no sun-resistance. And the appearance of such a listed building may not be changed. The installation of Umisol® kept the heat out and let the visible light in, all without changing the appearance of the building.

Private Residence in Merelbeke

Umisol® has a wide range of applications for private residences. The glass foil lets the light in and keeps the heat from the sun out. And the appearance of your glazing doesn't change. This means that people who live in apartment blocks can install the glass foil without any problems. The heat-radiation is stopped at the window itself, but the optical transparency remains unchanged. Umisol® also offers protection against break-ins. Shards of glass are held together in the event of a breakage, which makes it very difficult for burglars to gain access to a residence.
