InteriA - A2 Internal Wall Insulation (IWI) System

System Benefits in Depth;

• Outstanding Thermal Performance:
  Our systems help achieve and exceed current Building Regulation standards, contributing to lower energy bills and improved EPC ratings.
• Cost Effective: Internal Wall Insulation offers one of the most affordable pathways to improving thermal performance when external wall upgrades are not possible due to planning, conservation, or cost constraints.
• Acoustic Improvement: Alongside thermal gains, the stone wool insulation core provides outstanding acoustic performance by absorbing sound transmission through walls. This creates quieter, more comfortable living environments—critical in flats, terraced housing, or urban locations where external and neighbour noise can affect quality of life.
• Moisture Control & Breathability:
  Systems are designed to manage condensation and allow walls to breathe, preserving building health and long-term performance.
• Full System Warranty & Technical Support:
  Backed by the strength of the Rockwool Group, we offer full technical guidance, detail design support, and product training to ensure quality installation every time.
