Villa on Lake Como with thermal insulation 8 mm intervention on the façade

The project context: aesthetic constraints and thermal issues

In 2019 we worked on a villa in Menaggio, overlooking Lake Como, with a clear request from the project architect: drastically improve the building’s energy performance without altering its architectural appearance.

The presence of:

• traditional façades
• exposed stone surfaces
• pronounced thermal bridges around window reveals

made the intervention particularly delicate.

A traditional high-thickness external insulation system would have required significant structural modifications, changes to the architectural proportions and invasive work on thresholds, window sills and metal flashings (as well as potentially creating unhealthy indoor conditions such as mold and fire risks when synthetic insulation is used).

A different approach was therefore required.

Why choose thermal insulation 8 mm with Manti Ceramic

The objective was to achieve a truly high-performance thermal insulation 8 mm, capable not simply of slowing heat transfer but significantly reducing it through a high thermal reflectance system.

Unlike traditional insulation systems:

• it does not require thicknesses of 8–15 cm
• it does not alter architectural lines
• it does not create critical issues in construction details
• it allows precise correction of thermal bridges

Furthermore, it enables a tailor-made intervention, calibrated point by point across the building envelope.

The complete system applied in Menaggio

The intervention was carried out using an integrated Manti Ceramic system:

• 8 mm of Manti Ceramic High Density on the external façades
• Manti Ceramic Medium Density on thermal bridges (window reveals, structural junctions, under balconies)
• Transparent Low Density on exposed stone surfaces

This approach made it possible to intervene precisely, eliminating thermal discontinuities without compromising the original aesthetic appearance.

Thermal insulation 8 mm and measurable results over time

Today, several years later, the installed thermal insulation 8 mm system continues to ensure:

✓ Completely transformed living comfort
✓ More stable and drier indoor environments
✓ Average annual energy consumption reduction of 36%

The measured average reduction of –36% energy consumption is a result that would not have been achievable with either traditional thick insulation systems or lower-quality nanotechnological coatings.

Certified λ value: designing with real data

A crucial aspect for designers is the availability of objective and verifiable data.

Manti Ceramic is the only nanotechnological thermal insulation with a thermal conductivity value (λ) certified by an accredited third-party body:

0.001 W/mK for Medium Density

0.002 W/mK for High Density

This means:

• energy calculations based on verifiable parameters
• greater reliability in technical reports
• the possibility of formal certifications supported by official documentation

In a market where many solutions rely mainly on commercial claims, certification represents a fundamental differentiating factor.

The importance of correct application for the thermal insulation 8 mm Manti Ceramic system

An often underestimated factor concerns the workability of the material.

During the intervention on Lake Como, both installers and the site manager highlighted:

• smooth and easy trowel application
• absence of significant material waste
• simplicity in correcting details

A high-performance material that is difficult to apply often leads to mistakes, cracks and reduced durability.

On the contrary, easy application improves the final quality of the work and reduces the risk of long-term problems.

High performance, ease of installation and measurable results: this is what distinguishes an advanced technology from a simple thin coating.

FAQ – Frequently asked questions for technicians

Can an 8 mm thermal insulation replace a traditional external insulation system?

Absolutely yes. Manti Ceramic does not work by thermal resistance but by blocking the thermal wave, acting as a thermal shield.

Is it suitable for historic buildings?

Yes, especially thanks to its ability to reduce wall moisture levels and eliminate thermal bridges around decorative elements, cornices and façade details using the liquid version. It is highly appreciated by heritage protection authorities.

Can it be officially certified for energy calculations?

Yes, thanks to the third-party certified λ value.

Conclusions

The Lake Como case demonstrates that it is possible to achieve significant energy improvement with thermal insulation 8 mm, without altering the aesthetics and without invasive structural interventions.

When design, materials and installation work in synergy, the result is not just theoretical improvement but a concrete and measurable benefit over time.
