The Termoline door is made of 60 mm thick segments with a heat transfer coefficient of K=0.34 W/m²K.

Thanks to its special design, it features a double sealing system in critical areas where the greatest heat losses occur: connections between segments, vertical perimeter seal, seal in the door lintel, and the lower threshold part at the point of contact with the floor. In addition, a special "termobreak" seal is used between the steel structure of the guides and the garage walls, which allows for additional avoidance of heat losses of up to 15%.

It is worth noting that the frequency and duration of door opening have a significant impact on heat loss in the garage. Termoline automatic garage doors are equipped with excellent automation from the German company Berner, allowing for adjustable speed settings for opening and closing the door. Thanks to this, the door opening/closing cycle can be shortened by 30% compared to doors with other drives available on the market.
