Knauf Insulation - 50mm Knauf Acoustic (Apr) Insulation Roll

The primary purpose is to reduce airborne sound transmission between rooms or floors, creating a quieter living or working environment.

Yes, in addition to acoustic properties, the glass mineral wool composition provides a layer of thermal resistance, contributing to energy efficiency.

This product is primarily designed for internal partitions such as stud walls, floors, and ceilings. For external walls, other specialized solutions might be more appropriate.

Pre-perforated means the roll has lines or cuts at intervals, making it easier to split the insulation into narrower widths if needed for specific stud spacings.

One roll covers approximately 16.2 square meters.

The thickness of this particular roll is 50mm.

You will need a sharp knife or insulation saw for cutting, measuring tape, and optionally acoustic sealant for sealing gaps. Always use appropriate personal protective equipment (PPE).

Ensure there are no gaps around the insulation or where it meets framing. Air gaps significantly reduce soundproofing effectiveness. Check for and seal all penetrations (e.g., electrical boxes, pipes) with acoustic sealant.

Use a sharp, long-bladed knife or a specialized insulation saw. Ensure the insulation is laid flat on a stable surface for cutting. The pre-perforations can assist with initial breaks.

Always wear appropriate PPE, including gloves, a long-sleeved shirt, eye protection, and a dust mask during installation. Work in a well-ventilated area.
