Introduction

External wall insulation improves energy efficiency by adding a continuous thermal layer to building exteriors. Finished surfaces can mimic brick, render, or siding.

  • Boards or mineral wool blankets adhere directly to existing walls before cladding is applied.
  • Proper detailing around windows and doors prevents thermal bridging and moisture issues.
  • Finished thickness ranges from 50 mm to 150 mm depending on climate requirements.
