Preserving the character of Kolkata’s heritage buildings requires acoustic solutions that respect original finishes and decorative ceilings. Modern acoustic tiles and panels can absorb reverberation and improve comfort without concealing ornamental cornices or replacing historic plaster; the key is selecting materials and formats that are discreet, reversible where possible, and compatible with traditional interiors.

For sensitive installations we commonly recommend three approaches. Polyester Fibre Acoustic Panels are available in 2440 x 1220 mm sizes (9 mm and 12 mm) with NRC values up to 0.85 for the 12 mm option; they are lightweight, CNC‑customisable and offered in a wide palette (41 shades in 9 mm, 21 shades in 12 mm), so panels can be matched or trimmed to fit recesses and discrete ceiling zones. Perforated Acoustic Gypsum Ceiling Tiles and Boards come in 595 x 595 mm and 2400 x 1200 mm (12 mm) with acoustic performance to about NRC 0.60, are white by default, and are designed for easy installation on walls and ceilings, making them a natural match for plastered and ornate surfaces. Acoustic Baffles and Acoustic Ceiling Clouds (fibreglass and polyester fibre variants) provide selective, non‑invasive treatment: Acoustic Baffles in our range (for example 2400 x 300 mm at 30 mm thickness) offer NRC up to 0.9 and are lightweight and simple to hang, so the historic fabric remains visible while problem reverberation is treated.

Aesthetic flexibility is central to working in period properties. Polyester Panels’ CNC capability and extensive colour options allow customised shapes and insets that sit neatly within mouldings; Perforated Gypsum can be used where a plaster appearance is required; and Acoustic Ceiling Clouds or Acoustic Baffles permit targeted correction of speech clarity and echo without full ceiling replacement. Across our range you can achieve measurable acoustic benefits, clearer speech intelligibility and reduced background noise, while retaining or restoring original sightlines and ornamentation.

Amazone By Furnitech supplies these solutions from our Ahmedabad base across the sub‑continent, with products intended for interior use in humid climates and for retrofit conditions. To obtain a tailored quote for a Kolkata heritage project, please share your AutoCAD file or provide the approximate area in square foot (and photos if available). We will propose suitable combinations, for example Polyester Panels or Perforated Gypsum for full‑cover needs, and Baffles/Clouds for selective treatment, together with indicative pricing.
