The complete guide
Where HERTBER's black hexagon pack works best in the house
Hexagon tiles tessellate cleanly, which makes planning the layout the one step worth doing before the adhesive backing comes off.
Start from the centre, not a corner
Mark the centre of the area you're covering and dry-fit the first hexagon there before peeling any backing. Working outward from a centred tile keeps the pattern symmetrical even if the wall itself isn't a perfect rectangle — the trimmed, half-tiles end up at the edges where they're least noticeable, rather than in the middle of the wall.
What high-density acoustic foam is doing acoustically
Unusually thick at 5cm — deeper than most panels in the range at 0.9-1cm. In practice that means voices and hard reflective slap off a bare wall soften noticeably once a cluster of panels goes up — most people notice the difference within the first few tiles, well before the whole 24-piece set (30 x 30 x 5cm) is covered.
Getting real coverage from a 24-pack
A single pack rarely treats an entire wall on its own. Use it to cover the reflection points that matter most — directly opposite a microphone, speaker or the loudest hard surface in the room — before spreading tiles thinly across the whole wall for a cosmetic look that does less acoustic work.
