Go with Sin,
Go with Sincol!

The Sincol Silentia Acoustic Door is a complete solution for those seeking silence, privacy, and high performance in noise control between environments.Built with 100% solid filled doors, it utilizes specific internal engineering to block sound passage, making it ideal for offices, clinics, studios, bedrooms, meeting rooms, and any space where tranquility is indispensable.

To ensure maximum efficiency, the assembly features frames equipped with sealing gaskets along their entire perimeter, eliminating gaps that could compromise insulation. At the bottom, the door receives an automatic sealing device, which triggers a "drop seal" upon closing: it lowers precisely and completely seals the bottom gap, enhancing acoustic performance without affecting aesthetics or practicality in daily use.

We offer different attenuations according to the needs of the project:

Class C2 – 36 mm doors with 28 dB reduction
Class C3 – 40 mm doors with 29 dB reduction
Class C4 – 46 mm doors with 33 dB reduction

Each category was developed to meet specific levels of acoustic requirements, providing everything from lighter attenuation to robust insulation for environments that demand greater noise control.

The Sincol Silentia Acoustic Door is an architectural solution that transforms the environment, enhancing comfort, functionality, and quality of life.

Door Core Options

MDP

100% compact/solid (MDP), providing high density, excellent structural stability, and greater resistance to warping and deformation over time.

Solid Wood

100% solid pine, high-quality wood that guarantees maximum strength, excellent structural stability, and superior performance against warping.

Frames and Casings

Frames

Sincol door frames feature a reinforced structure, ensuring greater strength and safety.

The standardized 2mm radius design brings elegance and sophistication to the set. With structural reinforcement in moisture-resistant HDF and a UV insulating finish, they ensure extra protection against warping and humidity.

Casings / Architraves

They are produced with a moisture-resistant HDF base (more resistant to humidity) and can be laminated or coated, with widths of 50, 63, and 98 mm. They can be installed using a miter joint system or an H system, with adjustments of up to 25 mm.

How to Identify the Opening Direction of Sincol Doors

To correctly identify the opening direction of Sincol doors, stand outside the room and simulate the opening movement of the door:
If, when opening, the door swings inward and to the right, it is a right-hand opening door.
If the door opens inward and to the left, it is a left-hand opening.
