External insulation of solid masonry walls has the benefit of keeping the structure warm. The thermal mass of the masonry external walls helps to keep temperatures stable - storing heat in the winter and reducing solar gains in the summer.

External wall insulation is equally suitable for new and refurbishment projects.

Render on insulation is subject to greater temperature fluctuations than render applied direct to masonry. The following precautions should be adopted to minimise cracking:

• Reinforce the render with a mesh
• Provide movement joints at maximum 5 metre centres
• Use a light coloured finish to minimise the effects of solar gain
• Use a render incorporating a polymer and/or reinforcement fibres
