How to Compare Acoustic Quotations
By Thermofriz Team · Updated 25 October 2026
Compare acoustic quotations on complete installed scope, technical evidence, mounting, interfaces, exclusions, programme and acceptance rather than panel price alone.
Normalize the scope before comparing the total
A low price per square metre may cover only the visible finish. Another bid may include insulation, framing, fixings, perimeter finishing, equipment access and commissioning. List each required element and ask bidders to confirm whether it is included. Use the same quantity basis and record waste allowances. Where one quotation proposes a different system, compare the technical and practical consequences before treating the price difference as a saving.
Compare evidence for the actual construction
Ask each bidder to identify the proposed material, facing, thickness, backing and mounting. Review whether the supporting test report resembles that construction. A similar colour or nominal density is not evidence of equivalent acoustic performance. For isolation packages, include the details at doors, glazing, ceilings and service penetrations. A headline product coefficient should not be used as a guarantee for the completed room.
Read the exclusions and the delivery obligations
Confirm substrate preparation, storage, protection, access equipment, work by other trades, completion conditions and replacement responsibilities. Compare warranty terms and the proposed inspection and acceptance process. A useful clarification schedule records unresolved assumptions before award. Thermofriz can respond to a coordinated material or contracting brief; sharing the same drawings and performance responsibilities helps make the commercial comparison meaningful.
