Wall System 1 – Applied to Framed Structures

External wall insulation systems are extensively used on lightweight framed structures and direct-fix projects. The speed at which they can be erected and weatherproofed provides significant benefits to the developer. Removing the cladding from the critical path, bringing forward the internal trades and thereby shortening the contract period and eliminating the problems associated with brick and blockwork construction. This method of construction has proven extremely popular over recent years.

The details that follow demonstrate the use of the SPSenvirowall systems on lightweight steel frames although the principle operates equally effectively on timber frame structures.
