| Slat Material | Natural white oak veneer over a wood-based core, such as MDF or plywood. | Confirm whether the visible surface is natural veneer, reconstituted veneer, printed foil, or solid oak. Ask for a close-up sample. | Natural veneer should show genuine grain variation and should not be described only as “oak finish.” |
| Slat Dimensions | Common slat sizes are approximately 27–30 mm wide × 12–13 mm deep. | Compare the finished slat width, depth, edge profile, and dimensional tolerance stated on the technical sheet. | Use identical slat dimensions when comparing appearance, coverage, and pricing. |
| Panel Dimensions | Typical panels measure approximately 2400–2440 mm long × 600 mm wide. | Check whether the quoted dimensions are finished dimensions or nominal dimensions. Confirm available custom lengths. | Allow for cutting waste and verify that the panel length suits the installation height. |
| Slat Spacing | Visible gaps commonly measure approximately 13–15 mm. | Compare the center-to-center spacing and the percentage of exposed acoustic backing. | Consistent spacing is important for a uniform wall appearance and predictable acoustic performance. |
| Acoustic Backing | PET acoustic felt backing is commonly available in approximately 9–12 mm thickness. | Confirm the felt thickness, density, recycled content, color options, and whether the felt is bonded securely to the slats. | A thicker, denser backing generally provides better absorption than a thin decorative fabric layer. |
| Sound Absorption | Panel-only performance is often within approximately NRC 0.25–0.45, depending on the tested assembly and installation method. | Request a laboratory report showing the tested product, mounting method, air gap, and applicable standard. | Do not compare NRC values unless the test configuration and installation conditions are equivalent. |
| Installation Method | Panels may be fixed directly with screws and plugs or installed over timber battens for an air cavity. | Compare included accessories, recommended screw spacing, substrate requirements, cutting instructions, and concealed-fixing options. | A rear air gap can improve low-frequency absorption but may increase material and labor requirements. |
| Fire Performance | Fire classification varies by the oak finish, felt backing, adhesive, thickness, and mounting assembly. | Request a current fire-test or classification report for the exact panel construction, not a report for a similar product. | For commercial projects, require documentation accepted by the local building authority. |
| Formaldehyde Emissions | Wood-based cores may be offered in low-emission grades such as E1 or equivalent regional classifications. | Verify the emission class, test method, certificate validity, and whether it applies to the complete panel. | Low-emission documentation should cover the actual core and adhesive system used in production. |
| Surface Finish | Common finishes include clear matte lacquer, UV coating, or natural oil; sheen levels usually range from matte to satin. | Compare coating type, scratch resistance, color consistency, cleaning method, and repairability. | Request a physical sample because white oak color and grain can vary between production batches. |
| Moisture Suitability | Most veneered acoustic slat panels are intended for dry indoor areas rather than direct water exposure. | Confirm the permitted relative humidity range and whether the product is suitable for kitchens, bathrooms, basements, or coastal interiors. | Avoid installation in areas with persistent condensation unless the supplier provides specific moisture-resistance documentation. |
| Sustainability Documentation | Potential documentation may include recycled PET content, responsible timber sourcing, and low-emission certifications. | Ask for chain-of-custody documents, recycled-content statements, environmental declarations, and packaging information. | Prefer verifiable certificates or declarations instead of unsupported environmental claims. |
| Color and Grain Matching | Natural white oak commonly contains variations in grain direction, knots, tone, and lightness. | Ask whether batch matching, pre-production samples, or additional spare panels are available. | Order from one production batch whenever a continuous wall requires close visual consistency. |
| Customization | Common options include custom panel lengths, felt colors, slat spacing, edge trimming, and corner solutions. | Compare minimum order quantities, drawing approval procedures, tooling charges, and customization lead times. | Obtain a final approved drawing before production for projects with doors, outlets, or curved walls. |
| Packaging and Protection | Panels are commonly packed in protective cartons or reinforced bundles with corner protection. | Confirm moisture protection, palletization, carton labeling, panel quantity per package, and damage-claim procedures. | Inspect all packages immediately on delivery and photograph any visible damage before signing receipt. |
| Sample and Quality Control | A physical sample should represent the actual veneer, felt, slat profile, and finish offered for production. | Compare sample approval, pre-shipment inspection, dimensional checks, and replacement policy for defective panels. | Use an approved reference sample as the visual and dimensional benchmark for the final order. |
| Order Planning | Material quantity should include allowances for trimming, layout selection, damaged pieces, and future repairs. | Compare the supplier’s coverage calculation with the project’s measured wall area and installation pattern. | A practical allowance is often around 5–10%, depending on wall geometry and cutting complexity. |
