Seal Windows and Save Energy

Drafty windows and doors are one of the biggest energy wasters in your home. Therefore, it is especially important to ensure sealed and insulated windows during the cold season. With our window energy-saving calculator, you can quickly and easily calculate how much energy you can save. Depending on the window and gap size, you can save up to 40% on energy costs. So, it is worth paying closer attention to window sealing and door insulation.

Avoid Expensive Window Replacement with Window Seals

A complete window replacement is, of course, even more effective. However, such an intervention is very expensive and takes a long time. Especially during the cold season, having a construction site in your home is critical. With the solutions from tesamoll®, you can independently and easily seal and insulate your windows and doors. No craftsmanship skills are required. The sealing strips can be mounted on the window frame in just a few steps. Thanks to tesa adhesive technology, the seals hold firmly and reliably on your window - for many years. The tesamoll® Premium Flexible has a lifespan of up to 15 years. So, you can sit back and enjoy your warm home.

With our window energy-saving calculator, you can identify your individual savings potential. You enter the gap width and gap length. The system then calculates your personal savings potential based on many different factors. The current average kW/h price for new customers, the inflation rate, and product lifespan are taken into account.

In just three steps to your individual energy-saving potential:

01Calculate gap width

In the first step, you need to calculate your gap width. However, you don't necessarily need a ruler or measuring tape for this. With the candle test, you can easily determine your approximate gap width. Simply move a candle along the window frame. You can identify drafty spots by the flickering of the candle. The stronger the flicker, the larger the gap width. Make sure doors are closed during the candle test to avoid skewing the results.

With this step, you not only calculate the gap width but also directly identify the critical and drafty spots on your windows or doors.

02Calculate gap length

In the second step, you need to enter the gap length. Measure the height or width of the window, depending on where the window is drafty. This allows you to calculate the draft area and thus the energy loss. Additionally, you will know exactly how many meters of sealing strips you need.

03Energy-saving potential & recommended products

Done! You have quickly calculated your individual energy-saving potential. You will now be shown the most suitable products for your windows and doors. You will also see how much energy and costs you can save with each product.
