Heat is always lost through open doors, and the cold gets in. A small gap is all it takes to have a perceptible effect on the room temperature. Particularly in winter, a leaky door – no matter how small the opening – requires constant heating. The negative effect of a permanently incorrectly closed door is that you have to have the heating on all the time, so that the incoming cold air does not have a lasting effect.
Although you have actually done all that is required from your point of view – the heating is on and doors and windows are closed – the room temperature only increases very slowly and it takes a long time to reach the desired level. This could be caused by warped door leaves.
Sustained cold protection provided by your door through eco-lock®
If you equip your house or apartment with eco-lock®, you install significant cold protection for your door. Especially in winter, there are temperature differences of up to 35 degrees Celsius between the outside and inside of a door. Commercially available door leaves warp in a natural way for these reasons.
We guarantee an extremely long service life of our sealing system for windows and doors, which also does not allow cold air to flow through. Do away with unnecessary heating costs and a needlessly cold room by means of our closing system.
