HAVERKAMP Energy saving window insulation film

Increase energy efficiency
Reduce CO2 emissions
Save costs in summer and winter

Stop thermal energy loss through windows and doors

High energy consumption due to air conditioning? Improve the CO2 building balance with window films!

Are you looking for a cost-effective energy-saving solution for glazing? Insulation and heat protection should be given?
The high-quality low-E film from HAVERKAMP shields up to 82% of the sun's rays or solar energy in summer. In winter, this thermal film acts as a cold protection film and reduces energy transmission by up to 25% (depending on the glazing) by protecting against high heat loss through panes. Single glazing in particular can become energy guzzlers, as these panes of glass have a very low insulating effect. 
Ensure a continuous comfortable indoor climate and save high costs for energy supply!

Versatile effect of the low-E thermal window film

By optimizing room temperatures with the use of HAVERKAMP window insulation film, performance and concentration at work and the feeling of well-being at home can be significantly increased. The surface of the low-E film is protected with a HardCoat, which makes the film scratch-resistant and easy to clean. An integrated UV protection of 99.9% not only protects people in a room, but also reduces premature fading of interior colors.
Our low-E film, also known as insulating film or thermal film, is available as a classic retrofit for panes of windows and doors. The application of this window film is easy due to its quality and integrated adhesive, causing long-term adhesion to the glass surface.
The film from HAVERKAMP is available as a retrofit solution or as an interlayer film for processing in the glass manufacturing process.
Include HAVERKAMP window insulation films in your range of films and offer your customers an effective energy-saving solution.

HAVERKAMP Energy saving window insulation film


The efficiency of heat protection films and cold protection films (also called insulating films) has already been proven in several tests. At HAVERKAMP you have the possibility to calculate the effectiveness of the film in combination with your glazing by using the HAVERKAMP e-Calculator. In addition, HAVERKAMP's window insulation film has an integrated UV blocker, which significantly reduces the fading of interiors, furniture or exhibits.

Below you can break down the term with its synonyms:

  • Energy saving films are also commonly known as: Low-E films, insulating films, thermal films, climate films, energy saving films or classically window films with energy saving potential.
  • Energy saving films especially only for winter are called cold protection films and for summer heat protection films, heat protection films or classical sun protection films. Accordingly, a window tinting film (depending on the type) can also be an energy-saving film.

Yes, you can. Our film improves the carbon footprint of a property by reducing CO2 emissions. Subsequently, they save energy by relieving the air conditioning or other cooling devices in summer through solar radiation absorption and reflection, and leaving much more heat inside in winter through the integrated thermal insulation to the outside. This not only relieves the electricity meter, but also the wallet and contributes to climate protection in the long term! Our energy-saving window insulation film from HAVERKAMP can be installed directly on the existing glazing as a retrofit solution - this does not require any cost-intensive glass replacement.

In summer, window insulation film provides effective heat protection because it reflects sunlight and allows less heat from the sun's rays into the building. This reduces the cooling load of air conditioners or other cooling devices, which significantly saves costs, especially in buildings with a lot of glass. 
In winter, the film reduces heat loss to the outside. As a result, the interior of the building becomes more energy efficient and consequently requires less additional heat energy from radiators. Both effects of the window insulation film reduce CO2 emissions, which protects the climate. 
The improved indoor climate ensures greater living and working comfort, increases the ability to perform and concentrate, and enhances well-being.

Cleaning the mounted thermal window film is simple and is done with standard cleaning agents. The windows can be cleaned as usual. Since the surface of the film is scratch-resistant, it is also particularly durable. Only logical, please do not clean with strongly scratching sponges or the like.

A window tinting film can have various properties. In the classic sense, these include heat protection, sun protection and UV protection. If we look more closely at heat protection, this property can be likened to an energy-saving film.
However, a window insulation film is energetically effective in summer as well as in winter. A window tinting film is oriented towards the sun and its heat and is therefore primarily effective in summer. Thus, a window insulation film also has energy-saving properties in the summer months, but not in the winter months, as is the case with an energy-saving film.

A window film can always be removed without leaving any residue.
The first thing you need to do is to remove the edge binding of the glass pane, if any. When properly installed, the product is laid under the glass retaining strip or, if not present, sealed with special silicone. This must be removed. Then loosen one corner, spray the film with glass cleaner and pull it off as flat as possible. Depending on how long the film has been installed and how qualitative that is, this process goes quickly or the film repeatedly tears. All film residues should be removed.
In case of stubborn adhesive residues, you can spray them again intensively with glass cleaner and put the dismantled film -if not torn- back on the sprayed glass for the liquid to take effect. If the dismantled film is no longer intact, you can use a large garbage bag or plastic sheets as an alternative.
Once all adhesive residues have been removed, the last step is to clean and polish the glass as usual.

It is possible to achieve a maximum saving of 25%. But this statement cannot be generalized, because such a saving depends on several factors such as orientation of the object, existing glazing and usage.
At HAVERKAMP we have the possibility to calculate the effectiveness of the window insulation film with your existing glazing. Besides other technical, helpful values, you will receive an exact evaluation of the combination and its effectiveness.

As a flat glass film it can be mounted on most flat glass. Everyday work processes and activities are not disturbed. Installation is quick when performed by trained professionals. The film is effective as soon as it is installed.

Installation using the wet bonding method for bubble-free and clean installation:

  • If the flat glass pane is very dirty, clean it with a glass scraper and glass cleaner. There should be no more particles on the glass, as they cause unsightly inclusions.
    • remove the edge binding of the window. Always install the product under glass retaining strips or seal it after application with special silicone
    • thoroughly clean the surface to be glued
    • then spray the thoroughly cleaned glass with the mounting liquid (in the specified mixing ratio of HAVERKAMP mounting concentrate and water)
    • now spray your fingers with the mounting fluid to prevent unsightly fingerprints on the adhesive side of the window insulation film
    • now peel off the protective film on the back side
    • spray the adhesive side with HAVERKAMP mounting concentrate and apply it to the window.
    • squeeze out the water between the glass and the film with pressure from the center to the edges. Attention with thin panes!
    • the installation is completed when no more water bubbles can be seen and you see an even pane free of inclusions
