HEXAGO P-A FLAT · 432 × 500 × 77 mm · Sound Absorption Class A · αw 0.95
HEXAGO P-A FLAT is an acoustic panel. DEKOSTYL supports product selection, sampling and technical project coordination as official distribution partner.
The 2025 acoustic catalogue documents Class A, αw 0.95, NRC 0.95, SAA 0.95 and 250–5000 Hz for the shown configuration. The catalogue drawing labels the height as 433 mm; the current verified product record uses 432 × 500 × 77 mm.
HEXAGO P-A FLAT combines the modular hexagonal form of the HEXAGO series with a perforated flat front. The acoustic catalogue explicitly lists this variant as an absorber; the diffusion function of the three-dimensional P-A version is not transferred to FLAT.
For HEXAGO P-A FLAT, the manufacturer documents Absorption Class A, αw 0.95 to ISO 11654:1997, and NRC 0.95 plus SAA 0.95 to ASTM C423-17. The stated absorption range is 250 to 5000 Hz. The values relate to the documented test and mounting configuration.
“The catalogue presentation shows ash, oak and walnut wood variants.”
The catalogue describes a perforated 2D FLAT front, a box made from veneered wood and wood-based materials, and a core of absorbing wool and an acoustic membrane. HEXAGO P-A FLAT is therefore a multi-layer acoustic system rather than a solid-wood-only panel.
The catalogue presentation shows ash, oak and walnut wood variants. The current verified product record uses 432 × 500 × 77 mm; the 2025 technical catalogue drawing labels the height as 433 mm with a 500 mm side length and 77 mm depth. The latest manufacturer document should be used for specifications.
The required number of panels is not treated as a fixed number per square metre of wall area. The planning aid integrated on the product page sizes the system by room area; room geometry, reflective surfaces, use and the desired reverberation reduction should be considered for the specific project.
The catalogue states free-hanging mounting on screws and wall-cladding use. Typical applications range from recording and listening rooms to conference and office spaces and hotel lobbies. DEKOSTYL provides the available acoustic catalogue and verified dimension sheet and supports further technical requests as official distribution partner.

Acoustic data for HEXAGO P-A FLAT: Absorption Class A, αw 0.95, NRC 0.95, SAA 0.95 and absorption range 250–5000 Hz. The FLAT catalogue entry lists the function as absorption; diffusion values from the 3D P-A version are not transferred to P-A FLAT.
HEXAGO P-A FLAT is manufactured by Form at Wood in Europe. DEKOSTYL supports selection, sampling and technical project coordination as official distribution partner.

Price and terms are calculated according to quantity, timber, finish, specification and project requirements. Registration merely to view a price is not required.
Request project pricingHEXAGO P-A FLAT is used as a finished acoustic module. Cutting the panels is not intended.
Wood species and finish are selected for the complete panel. Separate edge veneering is not intended for HEXAGO P-A FLAT.
Project pricing depends on wood species and finish; shipping cost is confirmed according to order size and destination.
This calculator uses the same manufacturer room-size table as HEXAGO CM-A and HEXAGO P-A. It deliberately does not calculate a fixed number of panels per m² of wall coverage.
Planning guide, not an acoustic simulation. Room geometry, surfaces, furniture, glazing, use and mounting influence the result.
The SVG curve visually reproduces the HEXAGO P-A FLAT diagram published in the manufacturer catalogue. The underlying test documentation remains authoritative for exact frequency-specific values. HEXAGO P-A FLAT is documented with absorption as its acoustic function; diffusion values from the 3D P-A version are not transferred to the FLAT variant.
The DEKOSTYL project team supports technical coordination. Acoustic evidence, lighting options and bespoke manufacturing are reviewed by product and project with the relevant manufacturers or partner workshops.
