Hermetically sealing and perfectly insulating
The insulated pop-hole doors from Tulderhof have foam insulation on the outside. This foam is additionally protected with a thick anti-peck layer of rubber. A special guide causes the slide to fall against the wall when closing (see figure below). And the softness of the foam means the slide closes hermetically, making it completely draft-free.
