We help you employ the power of EWI to reduce heat loss from your domestic or commercial property.

Why Choose External Wall Insulation?

Why should you invest in external wall insulation? Solid walls, notorious for heat loss, can allow twice as much heat to escape compared to cavity walls. EWI offers a multitude of benefits:

  • Eliminates dampness and mould effectively.

  • Significantly reduces condensation.

  • It can be applied without disrupting your household.

  • Doesn't reduce your space's floor area.

  • Enhances weatherproofing and sound resistance.

  • Fills cracks and gaps, reducing draughts.

  • Extends the life of your walls.

  • Gives your property a fresh new look.

External wall insulation systems don't just save energy; they also add to your property's appearance. Rendex Facades offers an extensive range of finishes, from different render textures to a kaleidoscope of colours, brick slips, and even pebble dash systems.

Considerations For Installation

It's essential to address a few key considerations to guarantee a seamless and successful installation.

  • Planning Permission: Your property's appearance changes may require local council approval.

  • Accessibility: Adequate access to outer walls is essential for proper installation.

  • Problematic Walls: EWI isn't recommended for walls in poor condition.

  • Conservation Areas: Consult your local council if you live in a conservation area.
