Published figures.
Downloadable proof.
Every figure we publish has an independent lab report behind it. Free to download.
Three stages, no exceptions
Each stage clears before the next begins.
Before production
Density, purity, weight and dimension checked on arrival. Problems caught while they are cheap to fix.
During production
Dimensions, density and finish checked at set intervals. Custom work verified against the order.
Before dispatch
Visual, dimensional and documentation check. Only cleared product ships.
The measurements that matter
Absorption and transmission are separate measurements with separate scales.
Noise Reduction Coefficient
ASTM C-423 or EN ISO 354. Foam, felt, slats, wood wool, curtains.
Sound Transmission Class
SoundBlanket MLV at 2.5mm, 3mm, 4mm and 5mm. A report per thickness.
Fire performance
PET felt, foam, slats and MLV. Surface burning to ASTM E84.
Density and hardness
Foam density and indentation load deflection, batch to batch.
Dimensional tolerance
Panels, rolls and custom cuts. Tolerance stated on each data sheet.
Profile accuracy
CNC profiles verified against the cutting programme.
We publish what has been measured. Where a product has test data, the report is downloadable. Where testing is pending, we tell you directly.

Additional accredited laboratories
A tender calls for a specific lab or test, we arrange it.
A material rating describes the material. Your wall is an assembly.
Published figures compare materials. Predicting what you hear between two rooms happens at specification. Send us the construction and we will work it through.
