Compared to an internal curtain, a horizontal sun protection has the great advantage that the sun's rays from outside do not hit the window glass directly. This blocks heat energy and harmful radiation. Heat protection films as an alternative to curtains are also located on the outside and absorb some of the heat, but are less effective than blinds, for example. Dark-tinted films can also obscure the view of the outside. However, this was not a problem with a solution installed in the window frame, such as the WinClip Cool. You can attach this from the outside as sun protection for windows without drilling. Ventilation is then possible at any time as the windows can be opened as usual.

To install sun protection for windows from the outside without drilling, you do not need any tools and do not have to carry out any complex assembly. Since you don't use a drill, you avoid annoying dust and dirt. Instead of using screws and dowels, this type of sun protection is attached to the window frame. Use retaining clips for this. These ensure a stable and secure attachment that is durable and long-lasting. Some models are also environmentally friendly and sustainable because they can be reused.

Health-promoting temperatures are important throughout the home, especially in the bedroom, children's room or study. This also applies to offices and business premises. With sun protection for windows from the outside without drilling, you can ensure that it doesn't get too warm even in midsummer. If you have air conditioning, sun protection can help reduce its use. This also contributes to a better indoor climate.
