External Wall Insulation

The standard Building Insulation methods used in most homes in Britain

Internal Wall Insulation
  • Rooms can be heated quickly
  • Added insulation thickness reduces the internal room dimensions
  • Structural wall is cold and potentially damp, increasing the risk of condensation and freeze/thaw damage
  • Installation is disruptive for building occupants
  • Exposure to cold bridges, resulting in condensation, damp and mold
Cavity Wall Insulation
  • One of the most common building insulation methods
  • Cavity construction is expensive and time consuming
  • Thicker wall construction reduces the internal room dimensions
  • Limits options for thermal upgrades in the future
  • Outer leaf construction isn,t insulated or protected, increasing the risk of condensation and freeze/thaw damage
External Wall Insulation
  • Structural wall is warm and dry, increasing thermal performance and reducing building mainteance
  • Removal of cold bridges reduces the risk of condensation, damp and mould
  • The heat retention capability of the existing wall is fully utilised
  • Lightweight construction methods can be used, allowing for fast installation
  • Interstitial condensation can be eliminated, irrespective of climate conditions
  • Eliminates cracking caused by thermal expansion and contraction, even in mixed blockwork
Of the systems listed above, the one we useand feel is by far the most efficient and effective is external wall insulation. External wall insulation systems are suitable for both traditional and non-traditional solid wall housing and can significantly reduce heat loss leading to lower heating bills and carbon emissions. As well as improving thermal efficiency, external wall insulating systems at the same time revitalise the appearance of homes and can be a major contributors to the regeneration of run-down housing schemes
