Sandam - Soft sound insulation sheet

As thin as 0.7mm, but amazingly powerful in sound insulation.

SANDAM KR (for insulation and damping)

SANDAM KR is a plasticized PVC-based sheet loaded with a large quantity of metallic powder by special treatment; It has a basis weight of 2.1 kg/m2. This dense sheet is highly effective in insulating sound, achieving a noise reduction of 21 dB at 1,000 Hz. Containing much quantity of special metal power through, this paper-thin flexible sheet performs 3 to 5 dB better than usually calculated from the mass law.

As sound dissipates its energy while traveling across the sheet, SANDAM KR does never cause the coincidence effect in audible range due to breakthrough via multiple paths that is incidental to rigid materials. SANDAM KR. ensures leadpipe-cinch sound insulation.

* Features

(1) Higher insulation than based on mass law  

(2) Simple insulation. Just lay SANDAM KR over anything that is leaky.

(3) Maintaining its superior performance for more than 20 years.

(4) Fire retardent to ensure increased safety.

(5) Free from radio interference.

Deadening effect overpowering deafening noise of factories and studios.

SANDAM K-PRO (for insulation and damping)

Inheriting the virtues of SANDAM KR, SANDAM K-PRO is a high-performance sound insulator for professional use.

Measuring 1.2 mm in thickness and weighting 3.8 kg per square meter, it is the thinnest yet the most powerful insulator available in the industry today. It is so flexible that it can be bent and lapped freely wherever necessary to for perfect sound sealing workmanship. It eliminates such chores as double-sided adhesive tape caulking work, batten work, and other labor-taxing work.

SANDAM K-PRO is widely accepted for modern factories, music studios and recording studios to shut noise off the nearby area.

* Features

(1) Thickness: 1.2 mm ; Basis weight: 3.8 kg  

(2) Ease of insulation

(3) Highly effective for the sound shielding from factories and Studios

(4) Soft and flexible, and excellent in workability

(5) Fire retardent to ensure increased safety.

(6) Free from radio interference.
