Dark Cork Wall Tiles & Ceiling Tiles - Acoustic & Thermal Insulation

Bulk Discounts Available

Description

Dark Cork Wall and Ceiling Squares are 100% natural cork insulation tiles, designed to insulate walls and ceilings against heat, cold, sound, and vibration in any residential or commercial space. Each tile is composed of solid, expanded cork with a chunky texture and a rich, nearly black color, creating a distinctive, organic appearance. What sets these tiles apart is their exceptional insulating performance. Cork's unique cellular structure makes it one of nature's most effective insulators against temperature, sound, and vibration. These versatile 305mm x 305mm (12 inches x 12 inches) and 9.5mm (3/8 inch) thick tiles serve triple duty as a decorative surface covering, a thermal and acoustic insulator, and a functional tack board thick enough to hold pushpins. Available in packs of 4 or cartons of 144, they are ideal for offices, classrooms, locker rooms, exercise studios, game rooms, music studios, restaurants, and other environments where sound control, insulation, and organization are important.

A slight burnt scent may be present upon opening. This is a natural result of the production process and normally dissipates over time.

Due to the natural characteristics of cork and variations in screen displays, colors may vary slightly from product to product and from what is shown on your screen.
