Heat Action Day 2026: Film developer HAVERKAMP offers efficient solutions to enhance building resilience during extreme heat

June 2026

No costly renovations needed: Window tint and roller shades measurably lower the room temperature

Heat has now become the greatest health risk in Germany caused by the climate crisis. Extreme heat waves with prolonged temperatures above 40 degrees are becoming increasingly common. For this reason, the first nationwide Heat Action Day was declared on June 11, 2026, under the motto “Working Together to Prepare for Extreme Heat.” The goal: to raise awareness of the measures needed to effectively protect people and strengthen heat resilience in Germany.

Experts recommend taking precautionary measures. This applies to private households and businesses, and especially to hospitals, nursing homes, and doctors’ offices. The latter are often not (yet) structurally prepared for extreme heat waves. Interior spaces usually heat up quickly to unbearable levels. The most common cause of extreme heat indoors is glass facades and windows. Even with built-in air conditioning, there is little relief. Furthermore, operating the system is costly, as is its potential installation.

Sun control films directly lower indoor temperatures by up to 22 degrees
For more than 40 years, HAVERKAMP has demonstrated that sun control films are a versatile solution in this context and protect people from extreme heat. Since then, the film manufacturer has been developing sun control films in various versions. Today, there is a broad portfolio ranging from nearly transparent films to ceramic-coated tinted films and silver-reflective films. These films allow for flexible, quick, and efficient retrofitting. As soon as the films are installed, they begin to have a positive effect on the indoor climate. They reduce heat gain through the glass by up to 80 percent, thereby noticeably lowering the room temperature—and, most importantly, doing so immediately and over the long term. Installation is carried out cleanly and quietly, without disrupting daily routines.

As a long-term sun protection solution, HAVERKAMP films can help protect hospitals, nursing homes, daycare centers, schools, and offices from temperatures exceeding 40 degrees without the need for expensive renovations. Tests and measurements have repeatedly proven that this works.

HAVERKAMP Sun Protection Film: Top Rated by Stiftung Warentest
The reason lies in the quality. For example, one of the HAVERKAMP films was named the 2021 test winner by Stiftung Warentest when a total of 11 sun protection films were tested for heat protection and light transmission. One of two test winners in the “highly reflective window films” category was the HAVERKAMP Silver 20Rsr Primus Plus film, which reduces the room temperature by up to 22 Grand. HAVERKAMP offers its own digital calculator to determine the effectiveness of the desired sun protection films, taking into account the building’s existing glazing.

Roller blind systems with heat-protective film as a variable option
In addition to its sun protection films installed permanently on the glass, the manufacturer has also established roller blinds with integrated film panels on the market. These are suitable wherever flexible and adjustable glare and heat protection is needed—at computer workstations, in laboratories, or in conference rooms. The blind is disinfectable, easy to clean, and even when fully closed, it still allows a view to the outside.

Sun protection can be combined with burglary or shatter protection
To protect sensitive infrastructure, the manufacturer can also combine its sun protection films with additional product features: for protection against break-ins, burglary, flying shards, or vandalism, for example. “For example, we can combine sun and heat protection on the windows of a daycare center with shatter protection that prevents flying shards if a pane breaks. Or we can combine the sun control film for a laboratory with shatter resistance, so that the glass cannot be smashed,” explains Britta Meier, Sales Manager at HAVERKAMP.

For more than 40 years, HAVERKAMP has been developing a variety of sun-protective films. Today, the company offers a broad portfolio ranging from nearly transparent films to ceramic-coated tinted films and silver-reflective films.

The installation of these highly effective sun-protection films is carried out cleanly and quietly, without disrupting daily operations. HAVERKAMP has an extensive network of dealers and trained installers, ensuring professional installation.

The most common cause of extreme heat inside buildings during the summer is glass facades and windows. Installing window tinting films is a quick and effective solution that does not alter the building’s architecture.
