Why Wall Insulation Matters

Wall insulation can account for up to 35% of heat loss in uninsulated homes. Investing in proper insulation:

  • Helps reduce your heating costs year-round
  • Improves indoor temperature control and comfort
  • Reduces carbon emissions and environmental impact
  • Enhances the appearance of your property (with external insulation)
  • Increases your property’s value and energy rating

Whether you own a period home, detached house, or terraced property, we’ll guide you towards the most effective insulation system for your walls.

Tailored Solutions

Every home is different—so we don’t take a one-size-fits-all approach.

  • Internal Wall Insulation: Ideal for solid brick or stone walls where external insulation isn’t suitable (e.g., conservation areas). We use high-performance insulation boards and breathable materials to retain heat while preventing moisture build-up.
  • External Wall Insulation: Applied to the outside of your home with a protective render finish. It improves insulation and transforms the look of your property, while protecting it against the elements.

Our insulation specialists will carry out a full property assessment and recommend the right materials and techniques for long-term performance and visual appeal.
