What windows and bush fires have in common

In short: Both can waste gigantic amounts of unused energy. With one difference. It is easy to prevent energy losses around windows. A simple measure such as the regular use of roller shutters at old windows can reduce energy costs by up to 30%!
Windows are the largest thermal bridges in homes. Infrared images demonstrate this fact quite clearly. Long dark winter evenings provide ample opportunity to see just how many people still leave roller shutters open. Very bad for your wallet. Roller shutter automation could cure these problems quickly.
