About andrewcox

1200 Dowel Grille

Alvar Aalto’s classic touch is seen in 9Wood’s Dowel Grille. Its design lineage makes it timeless.

The 9Wood Dowel Grille Style wood ceiling offers a design where the individual wood member is deeper than it is wide. The standard panel width is 12″. Standard panel lengths are 4′, 6′, 8′, or 10′ (nominal). In non-seismic zones, Dowel Clips attach the grille panel to T-Bar main runners. In seismic zones a supplemental cross piece backer is typically utilized.

The Dowel Grille uses a pre-assembled panel fabrication process. The 1200 Dowel Grille style is often specified for member depths greater than 3″ to provide greater structural integrity. This product is easily accessible and installs efficiently to T-Bar grid via a dowel clip. The 1200 Dowel Grille Style should be considered when frequent accessibility is required or when deep members (>3″) are desired.

Acclimatization

Dowel Grilles must be cared for in a controlled interior environment (RH 25%-55% max; temp. 60°-80°) and installed only after reaching equilibrium moisture content. Should the building fall outside these limits, consult 9Wood for our Wood Ceiling Acclimatization for Professionals handbook.

Acoustics

The Dowel Grille can enhance acoustics via sound absorbing material placed over open reveals within the T-Bar grid. Insulation is typically provided locally.

Fire Rating

Individual members and components can be coated with Class I (A) Fire Retardant chemicals (solid wood use FR coatings, veneered particleboard use FR formulas). Particular species or styles have not been tested.

LEED

Dowel Grilles may qualify toward MR-3, MR-4.1/4.2, MR-5.1/5.2, MR-6, MR-7, IEQ-4.2 or IEQ-4.4. As all products are custom-fabricated, LEED credit opportunities are project by project. Please contact 9Wood for specifics.

MEP

The Dowel Grille permits MEP penetrations in the ceiling’s surface. Cut panels may require supplemental reinforcement. Fixtures and diff users must be independently supported.

Seismic

Dowel Grilles can provide seismic code compliance by means of mechanical direct screw attachment to T-Bar via supplemental cross-piece backers, eliminating the nonseismic dowel clips. Please consult local code or a licensed engineer for any additional requirements.

Species & Finishes

9Wood offers both domestic and imported species for the Dowel Grille. Clear, matte sheen finish is standard; custom stain matches are available. For additional information see our species article.

Suspension

Dowel Grilles are clipped onto 15/16″ heavy duty T-Bar main runners. Main runners are typically 2′ on center.

System Weight

Dowel Grilles typically weigh 2-4 pounds per square foot, depending on members per linear foot and species.
