Under-Door Drop Seals (Automatic Drop Downs) are primarily products that contribute to living comfort and safety. These products are tested by internationally recognized institutions, and the certified products fall under the certified product class.
The main benefits of Under-Door Drop Seals can be listed under the following headings:
Sound Insulation
In environments with doors equipped with under-door drop seals, they block sounds coming from the external environment (depending on the standards of the panel and surface used on the door). This helps create a quieter and more comfortable space.
Ease of Application
It is recommended to request the installation of drop seals during the manufacturing phase of living space doors. As a standard, there are two types of products: internally applied and externally applied. Even if it is not planned during the production phase of the door, installation can be carried out in later stages using Externally Applied Under-Door Drop Seals without removing the door panel. Albatur drop seals, with their patented mechanism operating from two points, provide the opportunity to be shortened up to 100 mm.

Provides Energy Savings through Thermal Insulation
In indoor environments with doors equipped with under-door drop seals, air passage from outside to inside and inside to outside is prevented. This helps save energy with heating systems in winter and cooling systems in summer.
Prevents the Passage of Dust and Smoke
On doors where drop seals are applied, they block dust and smoke that may come from under the door. It provides a sterile environment for individuals who are sensitive to dust.
Product Installation Features
The Albatur M30 0200 under-door drop seal mechanism features a system operating from two points. It can close the gap under the door up to 20 mm under standard conditions and up to 30 mm in special cases. The mechanism is produced in standard lengths and can be shortened by up to 100 mm. The compression height of the mechanism can be adjusted via an adjustment screw. On uneven floors, the seal applies full pressure to the ground thanks to its spring mechanism, regardless of surface irregularities. The detailed installation video of the product can be accessed at www.albaturas.com.
Prevents Light Passage
On doors where under-door drop seals are applied, light leaking from under the door is blocked. This increases living comfort in relaxation areas like hotels.
Prevents the Passage of Pests and Similar Creatures
On doors equipped with under-door drop seals, they prevent the passage of pests and similar insects that could enter from under the door.
Suitable for the Passage of Individuals with Disabilities
Since there is no mechanism or elevation on the surface during door transitions for individuals with disabilities, it does not pose any obstacle.
