A few words of introduction…
External Wall Insulation (EWI) refers to a layer of insulation applied to the external face of an existing wall. This layer of insulation can be finished with render or clad with an alternative facing material to protect it from the weather.
Here are some key points about External Wall Insulation.
Thermal upgrade
EWI is commonly installed to thermally upgrade solid masonry walls. It helps improve the energy efficiency of buildings by reducing heat loss through poorly insulated walls.
TYPES OF INSULATIONS
Stone wool insulation
Stone wool insulation boards, such as ROCKWOOL Comfortboard®, provide a continuous layer of insulation around commercial or residential building envelopes. They improve thermal performance and contribute to energy savings.
Semi-rigid insulation
Materials such as Comfortbatt® and Curtainrock® are semi-rigid stone wool insulation options suitable for exterior walls. They provide fire protection and maintain R-values.
Fire resistant insulation
ROXUL Safe® provides enhanced fire protection in perimeter fire barriers, construction joints and other fire stopping applications.
BENEFITS
Energy Efficiency
EWI improves the thermal performance of buildings, making living spaces warmer and more comfortable.
Acoustics
It can also improve sound insulation.
Fire safety
Certain EWI materials provide fire protection.
Compliance with modern standards
EWI helps to meet modern building standards.
Remember that professional installation is essential for effective external wall insulation. It’s particularly useful for solid wall buildings where cavity wall insulation is not an option.
