Gondolo Building Site - Cuneo
External redevelopment intervention with removal of existing paint. The cycle involved the application of the Antibacterial primer for surface consolidation, followed by the anti-salt Primer 12. The thermal insulation was created with 8mm thick Tillica, thus achieving performance equivalent to 18cm of EPS. The finish was performed with coloured Marmorino according to the customer's choices, completed with Bio Protective Mix for protection from rainwater and atmospheric humidity.

Thermal insulation - Valvasone
Internal thermal insulation intervention on a surface with pre-existing lime paints. Given the compatibility of the existing finishes, we proceeded directly with the application of the Antibacterial primer, followed by Tillica 3mm which guarantees insulation equivalent to 6 cm of EPS. The cycle was completed with smoothing mortar and lime milk finish according to the customer's specifications.
Results obtained
Transmittance measurement using KIMO TM210 instruments for 72 hours of sampling. Starting transmittance 1.9 W/m2K. Thermal transmittance of the wall after application = value that varies between 0.9 and 1.2 W/m2K. A reduction of between 40 and 55% was obtained compared to the non-insulated wall.

Massimo Pellegrino
Private CustomerResidential Thermal Insulation
2020“I was supported by Natural Calk throughout every phase of the project: from product recommendations to viewing completed works, and even coordinating the installers. The results were outstanding: I significantly improved energy savings and indoor temperature regulation, both in winter and summer. Two years after the product was applied, I haven’t had any issues with mould, and I didn’t need to make any structural changes.”
Giuseppe Gondolo
Private customerRiqualificazione energetica con sistema Tillica
2023“L'approccio di Natural Calk è stato subito chiaro e trasparente. Mi hanno presentato un prodotto innovativo, funzionale e pulito, seguendomi in ogni fase del progetto, trovando la soluzione migliore per la mia casa rurale. Il beneficio più importante è stato sicuramente lo spessore ridotto e l'ingombro totale minimo del muro a lavori finiti, ottenendo un eccellente risparmio energetico.”

2024 - 2025“The collaboration with Natural Calk was excellent. The Tillica system delivered outstanding performance on our Swiss worksites, effectively resolving challenges related to application thickness and structural constraints on both external and internal walls. Improvements in indoor environmental quality and the professional technical support provided throughout the project were especially valuable. I strongly recommend this solution to colleagues working on energy requalification projects.”
