Home theater, acoustic cork ceiling
Premium-grade smoked cork on ceilings and back wall, with engineered acoustic baffles behind the screen wall.
CK-12's smoked finish changes how light reads off the ceiling — instead of the warm honey tone of natural cork, the carbon treatment produces a charcoal surface with a velvet-like quality under dim lighting. In a home theater context this is exactly right: the ceiling should recede and absorb light rather than bounce it toward the screen.
The acoustic design called for cork on the ceiling and rear wall as the primary diffuse absorber, with engineered fiberglass baffles hidden behind the perforated screen wall for low-frequency control. CK-12 at 3mm contributes meaningfully to mid and high-frequency absorption — the acoustic consultant measured a 0.22 NRC improvement on the ceiling alone, which moved the room from slightly live to balanced.
Ceiling installation for cork is more demanding than wall installation because gravity works against the adhesive during cure. The contractor used a contact adhesive with a fast open time and pinned the panels at joints while the adhesive set. The smoked finish conceals the pin holes at the cork joint lines. No visible fasteners or trim strips were needed — the material's texture absorbs minor imperfections that would be visible on a painted or papered surface.
