How to solve acoustics and ventilation in interior design with perforated Hardboard
August 28 , 2026
Acoustic conditioning and ventilation in public spaces (offices, auditoriums, commercial premises) require cladding that allows air and sound to pass into insulation cavities without adding excessive weight or complicating installation.
In these types of projects, perforated high-density fiberboards have become one of the most efficient solutions due to their high mechanical strength and thin profile.
Acoustic performance: behavior of the sound wave
A solid, rigid panel tends to reflect most acoustic energy, causing echo and reverberation. By incorporating perforations across the surface, the behavior of the wall or ceiling changes:
- Wave passage: The perforations allow sound waves to pass through the board rather than bouncing off it.
- Cavity absorption: When installed over a battens framework with porous backing material, sound passes through the perforations and gets trapped in the absorbent layer.
- Reverberation reduction: This combination significantly reduces reverberation time and background noise in high-traffic areas.
Technical ventilation and heat dissipation
Beyond acoustic correction, board perforation plays an important role in climate control and space preservation:
- Continuous airflow: Facilitates air circulation, preventing moisture buildup or heat pockets behind wall cladding and suspended ceilings.
- HVAC return integration: Allows ductwork or air conditioning grilles to remain concealed behind the cladding itself, maintaining design continuity without breaking aesthetics with plastic or metal grilles.
- Heat evacuation in joinery: An ideal solution for fronts and backs in utility cabinets, radiator covers, or technical modules requiring constant ventilation.
Advantages of HTP Perforated board in interior design projects
To meet these requirements, at HTP Global Group we manufacture the HTP Perforated, a technical panel that stands out for three factors:
100% natural and formaldehyde-free
Composed of over 90% locally sourced Galician eucalyptus wood, we bind the fibers using the wood’s own natural lignin, without synthetic glues or added formaldehyde.
Formats and mechanical strength
Available in thin profiles (from 2.5 mm to 5.4 mm), it offers a density exceeding 900 kg/m³, which prevents the holes from crumbling during machining or installation, maintaining perfect planarity without sagging between battens.
Perforation patterns and job-ready finishes
It is supplied with calibrated 5 mm holes (in linear or diagonal pitch) and 7 mm holes (linear pitch), with a standard 25.4 mm center-to-center spacing. The board is available raw, pre-painted, or with decorative coatings ready for assembly or direct lacquering on-site.
