Dual-Layer Drywall for Fire, Acoustic & Strength Upgrades

When one layer isn’t enough – go double. Our 2-layer gips ceiling installation offers increased fire protection, better acoustic isolation, and added surface strength. Using two staggered layers of 12.5mm gips boards, we create dense, durable ceiling surfaces mounted to pre-built framing (wood or steel). This system is ideal for homes with overhead noise concerns, commercial ceilings requiring fire classification, or any space demanding improved structural performance. Installed using staggered joints and Norgips/Knauf guidelines, this service is engineered for quality.

  • Cuting and mounting of two layers of 12.5mm gips boards to existing ceiling framing
  • Proper staggering of joints between layers

  • Follows Standard double-layer specs: first layer attached at wider screw spacing (max 500 mm), second layer with tighter fastening
  • Basic cutouts for lighting or hatches (pre-marked only)
  • Waste handling for on-site board scraps
