Doors and windows are often the weak point of the building envelope if they are not properly designed and placed with great care.
They could be the cause of high energy loss.
At the same time, highly performing and correctly installed windows can reduce these losses by up to 80-90%.
To ensure air, water and noise tightness, it is necessary to use an adequate gasket system.
The automatic under-door gaskets are the best way to close the annoying gap between the door and the floor, avoiding the passage of air, water and noise.
Closing takes place with a guillotine movement (CCE patented) when the door closes, thanks to internal mechanisms with push rods.
Over the last thirty years, automatic under-door gaskets have undergone a great evolution, incorporating increasingly refined technologies and materials into this simple idea.
The use of co-extruded rubbers and special silicones in the construction of the under-door gaskets has made it possible to obtain excellent acoustic and fire resistance performance.
These characteristics are a must in the increasingly specialized requests of the world of both private and public construction and are certified by international laboratories.
In addition to the safety factor, an automatic under-door gasket with adequate performance guarantees a good level of comfort and significant energy savings in the environments where they are installed.
Traditional automatic under-door gaskets can give rise to noises due to the friction of the rubber on the ground when opening and closing the window.
To deal with this drawback, an automatic delayed hydraulic descent seal was created and presented on the market recently.
In summary, it is a gasket that closes on the ground 8 seconds after the door is already completely closed, to avoid friction with the floor, noise and abnormal wear of the gasket.
