Insects such as flies, mosquitoes and wasps are often uninvited guests in your own four walls. Especially in the summer months, patio doors are highly frequented passageways that are often open, but also allow a large number of insects to enter your home. heroal offers various options for effective protection against insects. You can choose between sliding insect screens for patio doors, sliding and lifting-sliding doors, as well as insect screens with a pivoting frame or swing screens for French doors. Pleated insect screens with vertical folding are ideal for very large openings, where sliding insect screens are not possible.
