Product information

Description

Insulation plug Koelner KES-90/20-MW — mineral wool, 90 mm thickness is a compact thermal and acoustic sealing element manufactured from mineral wool. Designed to fill circular and rectangular openings in walls, floors and ceilings, this 90 mm-thick plug combines heat resistance and sound absorption to limit heat loss, reduce noise transfer and contribute to fire-retardant building details. The product is intended for use where reliable insulation and mechanical stability are required around pipe penetrations and service shafts.

Advantages

The mineral wool construction provides stable thermal insulation and effective sound damping while maintaining non-combustible properties. Its uniform thickness and compressible edges enable a snug fit into irregular openings, improving airtightness and reducing thermal bridging. The material is dimensionally stable, resistant to rot and chemicals typically encountered on construction sites, and compatible with common sealing compounds and firestopping systems.

Suitable for

  • Sealing pipe penetrations through walls, floors and ceilings
  • Filling service openings around HVAC ducts and plumbing runs
  • Fire-rated partitions and passive fire protection details
  • Noise reduction in mechanical rooms and residential buildings

Key specifications

  • Material: mineral wool
  • Thickness: 90 mm
  • Shape: plug suitable for circular and rectangular voids
  • Functions: thermal insulation, acoustic damping, fire-resistant infill
  • Compatibility: suitable for use with common sealants and firestop systems

How to use

Measure the opening and, if necessary, trim the plug to achieve a tight fit. Insert the mineral wool plug into the penetration so that it fills the void evenly; compress the edges slightly to accommodate irregularities. Where required for code compliance or enhanced performance, apply a compatible sealant or mechanical fastening around the perimeter and follow any relevant firestopping system instructions. Ensure surfaces are clean and free of loose debris before installation to maximise contact and sealing effectiveness.

Usage recommendations

For optimal performance in fire-rated and acoustic applications, pair the mineral wool plug with manufacturer-recommended sealants or intumescent products and follow local building codes for penetration sealing. Store the plugs in a dry area and avoid prolonged exposure to moisture prior to installation.
