Gunspray supplies the full range of ROCKWOOL Insulation for hot pipes, slab stock, foil faced insulation and pipe insulation.

Rockwool’s HVAC insulation range includes products to suit pipes and both round and rectangular ducts of varying sizes.

Rockwool Ductslab

Ductslab and Ductwrap provide thermal insulation for a variety of uses including air conditioning, warm air and extractor ducts, either in plant rooms and boiler houses or outside. Ductslab is also good for thermally insulating cold water storage tanks, feeds and expansion tanks for temperatures of up to 230°C.

Ductwrap is made up of a lightweight, flexible insulation roll faced with reinforced aluminum foil; Ductslab consists of a semi-rigid insulation slab faced with reinforced aluminum foil.


  • CE marked
  • Water repellent
  • Non-combustible
  • Easy to handle and install
  • Chemically inert

HVAC Thermal & Acoustic Insulation

rockwool-thermal-insulationROCKWOOL HVAC Slab is versatile being designed to provide thermal and acoustic insulation for a variety of applications including warm air and extract ducts, where foil facing isn’t required.


  • Acoustically absorbent
  • No maintenance
  • Non-combustible
  • Chemically inert
  • Easy to handle and install
  • Water repellent

Lamella Mat Resilient Thermal Overlay

lamella-mat-thermal-overlayLamella Mat is formed from strips of ROCKWOOL’S stone wool insulation edge bonded to a flexible outer facing. Highly suitable for insulating heating and ventilation pipework and ductwork to overlay existing insulation as an upgrade.

It is also strong and resilient enough to resist flattening at bends and corners.


  • Maintains thickness on bends
  • Flexible
  • Compression resistant
  • Easy to handle
  • Excellent acoustic barrier
  • Excellent Thermal insulation

Pipe Section Mat (PSM)

pipe-section-matPipe Section Mat (PSM) is a rigid foil faced slab with factory machined grooves on the inside face designed to work with large pipe diameters. The distance between the grooves is carefully calculated to ensure that Pipe Section Mat closely fits the pipe so that the grooves tightly butting together. PSM is designed for thermal and acoustic insulation of large diameter pipes and ducts.


  • Suitable for large diameter pipes and ducting
  • High compressive strength
  • Ideal for use where storage space is limited
  • Easy to handle and install due to flat-pack supply

Rocklap H&V Pipe Sections

rocklap-pipe-sectionsRockLap H&V Pipe Sections are strong lengths of pre-formed insulation with a one piece, foil facing that has a self-adhesive lap. This adhesive lap ensures fast and easy installation: just snap the sections onto the pipe, peel off the backing tape and smooth down for a completely sealed joint


  • Fast and simple to install
  • No need for tape
  • Limited combustibility
  • Resilient, high performance barrier
