Thermal insulation: what it is and how to take advantage of Ecobonus 110

" Thermal insulation is one of the most valuable means of improving the energy efficiency of a property. It is also one of the interventions that is eligible (subject to necessary conditions) for the 110% Ecobonus. "

Thermal insulation is one of the most valuable means of improving theenergy efficiency of a property. It is also one of the interventions that is eligible (subject to necessary conditions) for the110% Ecobonus.

But what exactly is it? What are the benefits of this intervention? What materials are recommended for thermal insulation? What is the difference between interior and exterior coat? Here are the main features, our activities and advice about them.

What is thermal coat

Thermal insulation is a building envelope insulation system that can improve the energy performance of buildings. Among the benefits of thermal insulation is:

  • improved living comfort
  • excellent thermal insulation
  • heat/cold insulation
  • higher degree of sound insulation
  • lower energy consumption
  • lower spending on utility bills
  • Revaluation of the property if the property is upgraded to a higher energy class due to thermal insulation

Superbonus – 110% Ecobonus and the insulation system

From July 2020, the Relaunch Decree introduced the 110% Superbonuns, a maxi deduction for earthquake-resistant and energy-efficient work, installation of photovoltaic systems or electric vehicle charging systems in buildings.

The Superbonus was then extended by the Budget Law 2022 with different timing and percentages depending on the type of building.

It is important to remember that the proper installation of the thermal coat plays an essential role in ensuring its functionality and durability.

Teknoprogetti Engineering s.r.l. takes care of all aspects concerning the installation of thermal insulation, from assessing feasibility to the requirements to take advantage of SuperBonus to supervising the work.

If you are interested, the Teknoprogetti Team is available to assess your situation and guide you through the work. At the bottom of the article, you will find the contact form.

Interior or exterior thermal coat?

The term ‘thermal coat’ refers to an exterior thermal insulation system consisting of several parts:

  • glue
  • thermal insulation material in the form of panel
  • anchor plugs
  • background plaster
  • reinforcement layer or reinforcement
  • finishing plaster
  • accessories

If it is not possible to make an external thermal coat (due to architectural or condominium constraints), the alternative practiced is to make an internal coat with the possible insufflation in the walls of cellulose or cork for the purpose of improving the degree of thermal insulation.

Internal thermal insulation has the advantage of ensuring quicker action than external thermal insulation.

The activities of Teknoprogetti Engineering s.r.l.

For the correct design of the coat, it is necessary to know the characteristics of the substrate on which it will be applied, and Teknoprogetti is able to support designers by performing targeted “in situ” surveys.

Recently, we have dealt with:

On-site investigation in existing building used for residential purposes, subject to facade renovation with implementation of “coat” insulation in Cologno Monzese (MI).

The building on which we carried out our activities consists of 9 floors above ground with a reinforced concrete framed structure.

Purpose of investigation:

– Determination of the adhesion (pull-off) of facade finishes to the substrate consisting of concrete or brick

– Determination of the pull-out force of coat dowels

The Pull-Off technique allowed the measurement of the tensile strength of a given material or the determination of the adhesion strength between two different materials (typically adhesion value of mortars and plasters on masonry).


The investigations carried out were as follows:

  • 3 tests to verify the adhesion of a plastic coating to the substrate
  • 3 tests for verifying the adhesion of a ceramic coating to the substrate
  • Tests for verification of the tear strength of coat gussets
