The Building

Building pre-intervention

Historical farmhouse with no insulation or heating in the original structure. Renovation involved adding insulation while preserving historical elements.

The Solution

What is the Solution?

12cm thick layer of lime-based insulating plaster, Röfix CalceClima Thermo for exterior plaster, Röfix CalceClima Ambiente and Röfix Smooth Lime for interior plaster.

Why Does it work?

Specifically, if the difference in thermal resistance is such that calcium silicate panels allow a 5 cm reduction in total thickness compared to the thermal plaster, a significant gain in habitable space is achieved. This is particularly important in contexts where internal volumetric space is limited, and every centimetre of recovered space can improve the functionality and liveability of the rooms.

PROS

Improved thermal performance, preserved historical elements, use of natural and regional materials.

CONS

Potential high costs and complexity of renovation process.

Insulation material

Installation Method

Applied on exterior

Moisture Management and Technical Compatibility

Use of breathable lime-based plasters compatible with historical masonry.

Airtightness

Airtightness was achieved through the use of a continuous interior airtight membrane, carefully sealed at critical junctions such as window connections, service penetrations, and structural joints. This approach ensures a high-performance envelope and minimizes uncontrolled air leakage.
