Want a Safe and Saving Facade?

Our new range of fire resistant thermal insulation products offer an effective solution to the challenges of any rendered façade. With low lambda it secures good energy saving performance and saves as well climate as heating costs. Paroc Fatio and Linio are moisture resistant and has a very good dimensional stability securing the longevity of the façade.


Rendered facadeOur new range of thermal insulation products offer an effective solution to the challenges of rendered facades. With this wide range of products and structural configurations the right insulation for any rendering solution can easily be found. The benefits listed below are especially worth noticing.

Saves energy
Low thermal conductivity secures good energy saving performance. 

Protects against fire
Fire resistant PAROC® Stone wool is non-combustible and has a melting temperature of around 1000 °C. Therefore, together with the rendering, a PAROC® Stone wool insulation application creates an extremely fire resistant facade.

A durable facade
PAROC® Stone wool is moisture resistant and ensures the longevity of the facade. Thanks to the dimensional stability Paroc products do not change dimensions over time thereby avoiding open joints in the insulation layer.

Fast and easy installation
Easy to handle and install thanks to mechanical stability and low weight.

Flexible design
Enables the use of dark plaster on facades.

Efficient sound insulation
PAROC® Stone wool is a porous material and therefore an excellent choice to increase sound absorption and improve the level of comfort.

The Design of a Good Functional Rendered Facade

External Walls Provide Protection against the Elements
The external walls of a building function as a climate shield and should protect against cold, precipitation, strong winds, noise and fire. A good external wall structure, with the right insulation solution, is a prerequisite for a healthy and pleasant indoor climate.

The Economics of Thermal Insulation
The thermal insulation of a building can be seen as an investment that is expected to yield a return. The cost of the insulation is the capital employed while the future savings on energy bills are the return. The thermal insulation of a building typically amounts to about 3-5 % of total building costs. The pay back time for thermal insulation is fairly short in comparison to the life expectancy of the building. It has been calculated that the cost of building a house that uses 50 % less energy than average is only 5 % higher than the cost of building a standard house.

A Better Environment Through the Use of Thermal Insulation
More than industry or transport, it is a fact that buildings are the biggest single user of energy in Europe. The energy used in the heating and air conditioning of buildings accounts for more than 40 % of all energy used in Europe. This implies that a proportional amount of emissions is generated by the energy used by buildings.

The European Parliament passed the Energy Performance Directive in response to concern over emissions and in order to comply with commitments to the Kyoto Protocol. This will have profound implications on the insulation of buildings. The directive compels Member States to develop thermal insulation regulations into energy-use regulations, thereby setting requirements on the amount of energy used in the heating and air conditioning of buildings.

Both external and internal walls need to offer protection against fire. When selecting insulation for exterior walls, two factors should be taken into consideration: how the material reacts in fire and how the material resists fire. Almost all types of mineral wool are classified as non-combustible material, but PAROC® Stone wool has an exceptionally high melting temperature of around 1000 °C, providing longer protection. Therefore, rather than adding to the fire load, PAROC® Stone wool offers an effective fire resistant thermal insulation solution.
As traffic noise and other low frequency sounds have increased, requirements for effective sound insulation in walls have become stricter. Stone wool is a fibrous material which provides excellent sound absorption performance and when covered with external rendering creates a structure that protects against outside noise.
The question of additional thermal insulation is often raised during renovation. Additional thermal insulation is usually chosen in order to increase living standards, improve energy efficiency or as part of facade repair and maintenance.

Rendering Systems Can be Used on Various Supporting Walls
Thermal insulation rendering systems can be used on various supporting walls; on bricks, blocks or concrete
and on timber or steel structures. There are a number of different commercial systems that place numerous requirements on the insulation material - Paroc can provide insulation solutions for all these systems.

The use of stone wool insulation allows moisture to dry out due to the high water vapour permeability of the material. When designing the structure, ensure that water cannot enter the structure via cracks and leaking seams, and that any water inside the structure is allowed to dry out. Moistened structures dry out relatively quickly through the rendered insulation.

Relevant European Standards and Guidelines

The following standards and guidelines give detailed instructions for the components and the entire system. Our insulation solutions are designed in line with these. Based on these standards and guidelines every system owner can apply for an ETA (European Technical Approval).

ETAG 004: External Thermal Insulation Composite Systems with Rendering
This guideline sets out the performance of the systems for use as external insulation of building walls, verification methods used to examine the various aspects of performance, the assessment criteria used to judge the performance and the presumed conditions for the design and execution.
ETAG 014: Plastic Anchors for Fixing External Thermal Insulation Composite Systems to Rendering
This guideline sets out the basis for assessing plastic anchors to be used for fixing ETICS in a base material (substrate) made of concrete and masonry.
EN 13500: Thermal Insulation Products for Buildings - External Thermal Insulation Composite Systems (ETICS) Based on Mineral Wool - Specification
This standard describes product characteristics and includes procedures for testing, marking and labelling. ETICS are applied to external surfaces of new or existing walls to improve the thermal performance. ETICS also give protection against weathering and improve the appearance of buildings. They do not contribute to the stability of the walls to which they are installed. The thermal insulation is required for the load transfer to the substrate, but the standard does not cover the strength between the ETICS and the building surface to which it is fixed.
