External wall insulation systems.

An external wall insulation system or ewis is a thermally insulated protective decorative exterior cladding procedure involving the use of expanded polystyrene mineral wool polyurethane foam or phenolic foam topped off with a reinforced cement based mineral or synthetic finish and plaster. Weber external wall insulation ewi sometimes referred to as etics or eifs systems can simplify wall construction in the new build sector or extend the life of existing buildings by providing thermal insulation to keep the old structure warm and stable. The thickness of thermal insulation is dependent on whatever type is required in order to create. External wall insulation ewi which is also referred to as etics external thermal insulation composite systems is a method of insulating the outside walls of either a new or existing house and involves directly applying insulation panels to the walls of the building before finishing with a rendering system to provide protection from impact.

Insulating with cork image credit. Exterior insulation and finish system eifs is a general class of non load bearing building cladding systems that provides exterior walls with an insulated water resistant finished surface in an integrated composite material system in europe systems similar to eifs are known as external wall insulation system ewis and external thermal insulation cladding system etics. 100ml expanded polystyrene boards are fixed to the external wall and then reinforced with the special 155ml wall plugs base coat fibreglass mash and protective acrylic finish available in different colours and structures. Our range of bba approved external wall insulation systems ewi and solutions that have been tried and tested for over 30 years.

Zip system r sheathing is the simple all in one structural panel with built in exterior insulation. Our insulation delivers a number of benefits beyond thermal performance in external walls such as best in class fire resistance exceptional noise reduction water repellence as well as vapor permeability and dimensional stability meaning excellent fit and real world performance for the lifetime of the building. Featuring integrated moisture air and thermal protection zip system r sheathing completely reimagines traditional wall assemblies by streamlining exterior water air and thermal management. Permarock products ltd is a leading uk manufacturer and supplier of external wall insulation and exterior render systems.

Most external insulation systems deal with this challenge through the inclusion of a vapour barrier between the wall and the insulation but it is worth checking with your manufacturer supplier.
