Fire Properties

  • Non-combustible – tested to SANS 10177 Part 5
  • Class A1, s1, do according to EN 13823
  • EUROCLASS A1 – EN 13501-1 

Thermal Properties

Contributes to indoor comfort and lifelong energy savings by reducing heat loss/gain due to the inherent thermal insulation properties.

A dry wall system correctly designed and insulated will offer the same or better thermal properties than a conventional brick and mortar construction.

Accoustic Properties

Offers exceptional acoustic properties and enhances indoor environmental quality by absorption of noise. Cavitybatt/Cavitylite reduces sound transmission to and from a room or building.

A dry wall system correctly designed and insulated will offer the same or better acoustical properties than a conventional brick and mortar construction.

Description

Cavitybatt and Cavitylite have been specially developed for insulation within steel frame structures, timber frame buildings and dry wall systems. Cavitybatt and Cavitylite is manufactured using high quality glass wool and is glass tissue faced on one side for ease of handling and improved rigidity.

Applications

  • Steel frame buildings
  • Timber frame structures
  • Dry wall systems
  • Designed for use in cavity walls but may effectively be used on top
  • of ceilings, along the roofline, or within masonry wall cavities.
  • Cavity fill

Features & Benefits

  • Lifelong energy savings
  • Exceptional acoustic properties
  • Lightweight and easy to handle
  • Maintenance free
  • Long product life – will not readily age
  • Self supporting – will not sag
  • Compression packed – to reduce volume and optimise transport and storage

Tools Needed for Installation

Batts are designed around the frame/stud system for ease of installation, therefore minimal tools are required. A sharp knife/blade will come in handy for off-cuts and for slitting batts to fit over piping and conduits.

Installation Instructions

  1. Open packaging allowing space for the initial immediate recovery of compressed product
  2. Push individual batts firmly into the cavity space with glass tissue facing on the exposed side
  3. Use a sharp knife to slit the Cavitybatt to encapsulate piping/conduits
  4. Use a sharp knife to cut batt around any plug points
  5. Make sure that there are no gaps, which will cause thermal and noise leakage

Architectural Specifications

Install (51/63/100/102) mm thick self-supporting non-combustible lightweight, glass tissue faced Glasswool “Cavitybatt insulation”, offering a thermal resistance value of (1.34/1.66/2.63/2.68) m² K/W for heat and/or acoustic control. Install strictly in accordance to manufacturer’s detail and specification.

Cavitybatt Specification

Tools Sharp Knife
1. Install drywall framework as per manufacture’s specification.
2. Install Isover Cavitybatt insulation progressively as boarding proceeds.Cavitybatt insulation should be tightly butted together and against the studs. Use a sharp knife to slit the cavitybatt to encapsulate pipes.
3. Clad the remaining side of the drywall.
