Hz acoustic panel 071 must be mechanically fixed via 4 pre-drilled holes in the pre-treatment. Areas of use are ceilings and walls where removal and minimisation of noise through construction are desired. Fixing can be done directly on solid support surfaces or on laths.

Hz acoustic panels consist of custom-made recyclable hard rock wool sheet, laminated with a custom-made 10 mm waterproof glass granulate sheet, of which 100% is recycled material.

Panels are stored free of frost and moisture. The temperature must not exceed 40 degrees Celsius and panels must not be stored in direct sunlight.

The supporting surface must be dry, free of grease and loose substances. Loose plaster, chalking and other non-solid surfaces are removed and supporting surfaces are primed with hz primer. Previously painted surfaces must be primed with hz primer. Hz acoustic panels are fully glued with flexible tile adhesive, and a notched trowel with 6-10 mm notches is used, depending on the evenness of the supporting surface. The adhesive is pressed into the glass wool sheet, and the sheets are glued together with an offset of at least 15 cm. Hz fill is used on all edges of the panels. Read the supplier’s instructions.

At 20 degrees Celsius and 50% RH, the fill for joints and holes is dry after 1 hour, and can then be sanded with a drywall polisher connected to a vacuum cleaner. Cleaning can then be carried out the same day.
