FassaLime and Ex Novo: Restoring Buildings with Breathable, Sustainable Lime Solutions

As the construction industry continues to prioritise sustainability, heritage conservation and healthier building environments, lime-based construction is enjoying a well-deserved resurgence. Fassa Bortolo's FassaLime range combines centuries of traditional knowledge with modern manufacturing to provide high-performance lime mortars, plasters and finishes suitable for both restoration and contemporary construction.

At the heart of the range is Ex Novo, a colletion of specialist lime products and application cycles designed to restore existing masonry while maintaining the character and integrity of historic buildings. Whether repairing damaged renders, replastering solid walls or carrying out sympathetic refurbishment works, Ex Novo systems offer excellent compatibility with traditional substrates, helping to protect buildings for generations to come.

Unlike cement-based alternatives, lime products are naturally breathable, allowing moisture vapour to pass through the building fabric. This helps regulate internal humidity, reduces the risk of trapped moisture and can minimise issues such as condensation, damp, and mould growth. The result is a healthier indoor environment alongside improved durability of the building structure.

Fassa Bortolo's carefully developed Ex Novo cycles provide specifiers and contractors with complete system solutions for a variety of refurbishment requirements. By selecting compatible primers, base coats, finishing plasters and decorative coatings within the recommended cycle, installers can achieve reliable, long-lasting performance while preserving the architectural character of heritage properties.

The FassaLime range also contributes to improved thermal comfort. When used as part of a complete wall build-up, lime plasters help regulate internal temperatures through their moisture-buffering properties, while selected FassaLime systems can be combined with insulation solutions to enhance the thermal efficiency of both new-build and renovation projects.

Acoustic performance is another important consideration in modern construction. Lime plasters provide additional surface mass which can contribute to reducing airborne sound transmission when incorporated into suitable wall and ceiling constructions. Combined with complementary insulation systems, FassaLime solutions can help create quieter, more comfortable internal spaces for residential and commercial buildings alike.

Sustainability remains central to every FassaLime solution. Lime production requires lower firing temperatures than traditional cement manufacture, contributing to reduced embodied carbon. In addition, lime naturally reabsorbs a proportion of carbon dioxide during the carbonation process, further supporting environmentally responsible construction practices.

From sensitive heritage restoration through to contemporary sustainable design, Fassa Bortolo's FassaLime and Ex Novo systems provide architects, specifiers and contractors with complete, breathable lime solutions that deliver durability, compatibility, thermal comfort and acoustic benefits without compromising the long-term performance of the building.
