Important — please read
These are indicative quantities using standard spacing (ceiling sections 457 mm, studs and battens 600 mm, grid 1200 × 600 mm). Panel sizes for VOX, PARÉ and Univicoustic are typical catalogue sizes; aluminium quantities assume standard sections. Drops, coves, openings, wind load, glass thickness and site conditions change the result. This is not a structural design, quotation or guarantee. SIA confirms the final BOQ and price after a site survey or drawing review.
