LINEA Grille is a highly customizable panelized linear wood slat / wood blade system designed for interior and exterior wall and ceiling installations. LINEA Grille is composed of wood slats oriented 90° to the mounting surface. LINEA Grille is available in a wide variety of solid wood or real wood veneer options, comes in standard or custom sizes, in standard or custom spacing configurations and in standard, custom or simulated finishes. When combined with acoustical insulation, LINEA Grille can achieve exceptionally high acoustic performance.

Performance Info


LINEA Grille panels without additional acoustic insulation, will act as a sound diffusor and should be considered acoustically transparent. When the LINEA Grille is paired with acoustical insulation or duct liner behind, the panels can achieve high sound absorption

Fire Rating—Solid Wood:

FX Lumberguard or FX Lumberguard XT chemical fire retardants are factory applied to all LINEA Grille wood slats prior to further finishing to achieve a Class A Fire Rating when tested to ASTM E-84 (USA) and CAN/ULC S102 (Canada). When site cutting is required, FX Lumberguard can be re–applied to the cut locations and re–sealed to bring the panel back into conformance. Other topically applied chemical fire retardants or intumescent finishes may be used in lieu of FX Lumberguard to achieve Class A Fire Rating. In some cases, the specifying consultant may need to file an Alternate Solution with local authorities for approval. LINEA suggests consulting with local building code
consultants during the specifying stage to avoid any potential issues related to Fire Rating

Fire Rating—Veneer | Composite:

LINEA Grille panels with real wood or engineered wood veneers are laminated to Class A Fire Rated Composite MDF or Particle Board cores. The combination of Wood Veneer and Finish is less than 1mm thick (0.5mm in most cases) and therefore should not be considered significant to the overall rating.


LINEA Grille panels are engineered for applications in all seismic areas when installed per LINEA installation instructions

Site Conditions:

Wood products are hygroscopic in nature and must be stored, installed & maintained in a controlled building environment. Temperature range should be maintained between 60° – 90° F (15° – 32° C). Relative Humidity range should be kept within a minimum 25% – max. 55% (not to exceed 20% RH from peaks to valleys). Failure to maintain site conditions will void the LINEA warranty.
