Spray-on thermal insulation

Discover our solution that provides buildings with effective thermal insulation: the spray-application of an insulating coating helps to limit thermal bridges.

Our expertises

Importance of thermal insulation

Thermal insulation refers to all materials and techniques used to insulate and limit heat transfer between cold and hot environments, i.e. thermal insulation of roofs, ceilings, walls, floors, cladding. Thermal insulation is used in the textile, automotive, industrial and, of course, construction sectors. Insulation improves thermal performance, thereby helping buildings maintain a comfortable indoor temperature.

Spray-on thermal insulation limits thermal bridges

A global approach should be taken when planning building insulation works, paying close attention to thermal bridges. Even where high-performance insulation products are used, the existence of areas with lesser or no protection in the building's thermal envelope creates thermal bridges that cause excessive heat loss, damp spots and, therefore, higher energy consumption.

Due to its application method, spray-on thermal insulation can cover the entire surface to be insulated, creating a continuous coating that limits thermal bridges.

Spray-on thermal insulation, also referred to as flocking, consists in the pressurised application of mineral wool fibres combined with a binder, using special machines, aimed at achieving excellent thermal insulation performance.

Benefits of applying thermal flocking to a building

Applying flocking or spray-on insulation to a building helps to reduce:

Its energy consumption, thereby saving energy
The emission of greenhouse gases
The risk of condensation
- Temperature differences, thus ensuring stable thermal comfort all year round.

Projiso thermal flocking: Our spray-on fibrous and slurry coatings for insulation

Projiso manufactures and markets Fibrexpan^® a fibrous spray-on insulation coating designed to improve building thermal insulation.

Fibrexpan^® can be applied to all types of substrate, provided that the appropriate bonding agent is used.

The latest 2020 thermal regulation = RE 2020

The environmental regulation aims to encourage the building industry to design positive energy buildings, i.e. buildings that produce more energy than they consume.

It was established to meet three objectives:

Improve building energy performance and promote energy decarbonisation
Reduce the environmental impact of new buildings
Ensure optimal comfort

This demonstrates the importance of designing buildings to include spray-on thermal insulation.

RE 2020 recommends that thermal bridging and air tightness (for which the "blower door" test is now mandatory in collective housing) should be dealt with as effectively as possible.
These two criteria guarantee high-quality implementation that significantly improves a building's thermal performance, thereby enabling energy savings.
The environmental regulation (RE 2020) imposes threshold values for thermal bridges in new buildings.

Based on RE 2020, the burden of the emissions produced throughout a building’s lifetime, from "cradle to grave", via the construction and operating phases, is taken into account.
The calculation factors in the share in the environmental impact of each of the seven stages in a building's construction: extraction of raw materials, manufacture of materials and products, transport, building construction, building operation, renovation and rehabilitation, and destruction.
