Application

Designed for installation as a thermal and acoustic insulation around heating and ventilation duct applications or vessels across both process and HVAC markets.

Description

Stone Mineral Wool sections, which are orientated by 90° and laminated to a foil, give greater integrity of thickness due to a higher compressive strength particularly around corners of rectangular units. The foil face provides an efficient vapour barrier.

Features and benefits:

  1. Wide range of thicknesses from 25 to 100 mm: Upgrades the thermal performance to the design thermal resistance of the location.
  2. Foil Facing: Provides an effective vapour barrier and prevents fibre migration.
  3. Bespoke sizes available: Project specific designs can be made without waste on site.
  4. Can be used on both circular and rectangular ducts: Lamella has a greater integrity of thickness round corners.
