Re: Flooring renovation acoustic documentation — Unit [___]

Dear Board,

I am requesting approval to install new flooring in my unit. Per the association's
flooring requirements (CC&Rs / architectural guidelines), please find attached the
acoustic test documentation for the complete flooring system:

- Flooring: [product name], [thickness] — impact sound reduction [___ dB, standard ___]
  (test report attached)
- Underlayment: Forna [3mm / 6mm / 12mm] natural cork underlayment — rated
  IIC [___] / STC [___] on a 6-inch concrete reference slab [with / without] suspended
  ceiling (test statement attached)
- Combined system: [flooring + underlayment] — ΔIIC [___] per ASTM E2179
  (test summary attached)

Assembly calculation:
Building's existing floor/ceiling IIC (per building records): [___]
Tested contribution of flooring system (ΔIIC): + [___]
Expected assembly rating: [___]

The underlayment is natural cork — fire-inhibiting, with no toxic off-gassing in
combustion, and GreenGuard Gold / ECO Institut certified for indoor air quality
(certificates attached). Installation will be floating (no adhesive to the slab)
with perimeter expansion gaps per the manufacturer's instructions, by
[installer name / the owner], beginning [date] and completing within [___] days.

I would be pleased to provide further documentation or samples on request.

Sincerely,
