Sandam - Soft sound insulation sheet
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.

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.
