Solid Wall Insulation

Why Insulate?

Over a third of the energy required to heat a property escapes through the external walls. External Wall Insulation (also known as an Insulated Render System / Solid Wall Insulation is the perfect solution for ‘hard to heat’ homes.

The system involves the mechanical and/or adhesive fixing of insulation boards to the outside of a property. This is encapsulated with a mesh reinforcement, a base coat and a final decorative finish such as render or brick slips. This layered method encases the property and helps prevent heat from escaping unnecessarily.

Wetherby have an impressive portfolio of systems allowing Clients to confidently specify a flexible building solution that not only conforms to current building regulations and energy standards, but offers a wide choice of final finishes to fully meet the client’s aesthetic expectations.
