Exterior Wall Insulation - Rockwool

Outside walls are where heat loss or heat penetration most commonly occurs in the majority of buildings.

For more information, please visit our website.

Exterior wall insulation can significantly moderate this – improving the building’s energy efficiency, as well as cutting CO2 emissions and reducing fuel or cooling costs.

Exterior walls come in different shapes and forms. These range from cavity walls to rendered systems and façade cladding, for domestic, commercial and industrial buildings. Each type of external wall has its own advantages and disadvantages. They appeal to the building owner in one way or another, by assuring good energy performance that meets local requirements.

Key benefits:

• Less heat loss
• Lower energy bills
• Protected building structure
• Lower temperature fluctuations
• Fewer damp issues

ROCKWOOL external wall insulation is central to developing energy-efficient walls, and meets modern code requirements by providing continuous insulation for residential, commercial and industrial buildings.

Fire resistance also adds an extra layer of safety. Our noncombustible stone wool fibers are based on volcanic rock and capable of withstanding temperatures exceeding °F ( °C).3 – ideal during construction or renovation of high-rise buildings. Water resilience also meets the increased need for flood defences in many properties.

Installing exterior wall insulation

With the various solutions available for external wall insulation, there are many different installation requirements. For cavity walls you can install granulate, partial and full fill slabs, while for timber frame you need products with flexible edges.

High-density slabs or lamellas are necessary for ETICS and ventilated facades, with prefabricated sandwich panels or slabs with cut-outs best for metal walls. More detailed instructions can be obtained from your local ROCKWOOL organisation.
