ETICS

Why do we need ETICS?

A building’s façade is normally the largest surface area between its internal and external environment – where a great amount of heat loss can occur. Thermal insulation of the external walls from the outside is an efficient way of protecting against thermal energy loss.¹

ETICS works to insulate the vertical envelope of a building – whether an individual detached house or entire apartment block. This prevents temperature load, weather related damage and condensation problems.

Key benefits include:

Preventing heat loss by reducing thermal bridging
Improving energy efficiency of an entire building
Low cost solution to upgrading existing properties
Installation without inhabitants having to move out

Installation

ROCKWOOL ETICS products are highly robust, with a great fitting ability that can adapt to irregularities in external walls during installation.

Installing can be done on a layer-by-layer basis. It generally requires a few components, including the insulation material, anchors, adhesive, reinforcement, base coat and finishing layer.³ Each can require a different installation method.

Key tips⁴:

Measure the façade – Knowing the size of the external wall being insulated is essential, so you can make sure you have the right amount of insulation material.
Prepare your tools – ROCKWOOL slabs and boards are easy to cut with a long-bladed knife or insulation saw. Have one on hand if you need to resize your insulation.
Choose the best product – Check those available in your area and decide which is best for the building.

Calculator and savings

ROCKWOOL external thermal insulation systems can offer different products such as slabs (mono or dual densities) and lamella, in a range of thicknesses. In some markets, we also offer the whole ETICS system known as REDArt.

The thickness of insulation applied to an external insulation system will depend on local regulations and requirements. Additional factors such as the size of the wall being insulated, its base characteristic and finish will all affect the exact cost of installation.

Technical support is commonly available from your local ROCKWOOL organisation to work out the precise products and thicknesses required. Certain tools may also be available to help work out the current thermal performance of your walls.

With its smart fibre structure, ROCKWOOL stone wool adapts to irregularities, preventing sagging or gaps in the insulation layer. This helps keep warmth or cooler air in, thereby preserving thermal comfort.

Case Studies

The challenge

Bethesda Children’s Hospital in Budapest founded the Mother’s House – designed to provide beds and living facilities for mothers whose children face the prospect of long-term hospitalisation. Involving renovation and extension to its existing building, this required low operating costs and comfortable living conditions.

The solution

Frontrock was used to insulate the external walls. This two-layer stone wool board was applied to the external façade.

The results

Hundreds of mothers can now stay close to their children each year. Installation of Frontrock has improved thermal insulation, lowering energy costs and creating a comfortable internal climate.

High levels of fire resilience and sound insulation have also helped make Mother’s House a safe and quiet environment. In addition, Frontrock prevents mould and bacteria forming – maintaining the hospital’s high hygiene standards.
