ISOBELL is the perfect solution to eliminate mould, cracks and micro-cracks and to avoid rising damp.

It will provide you marked energy saving and will make your house a better place to live in.

Its lightness and flexibility will allow you to renovate and insulate inside and outside walls, increasing their energy efficiency and protecting the house against the passage of time and adverse weather.

The special inner structure is composed of two outer resin-rich layers, and an inner resin-free felt layer: the central resin-free layer acts as compliant connection, limiting or also avoiding the transmission of deformations from the interior to the exterior resin-rich layers. The material itself goes up to 130 % deformation before breaking.

Mould on the walls is one of the most frequent problems in our homes. It is a fungus that appears in the form of green or black stains on the surfaces of walls and ceilings. When the damp in a room becomes excessive and cannot escape, it tends to fall onto the cold surfaces of the walls (mainly external walls), and into the heat bridges (boxes, window sills, stringcourses, etc.). Warmer air, full of damp, condenses and fosters the formation of mould in these points.

The formation and growth of mould can be prevented efficiently using ISOBELL.

Cracks often form in the plaster of old houses due to infiltration and damp. In this case, cracks of different sizes appear on the walls. It is important to step in as soon as possible when this happens, to prevent the damage from spreading to the surrounding areas.

Owing to its special layered structure, ISOBELL can limit the transfer of deformations from the inner to the outer layers by acting against the cracks and micro-cracks.

Rising damp is one of the most commonly found types of damp and affects both old and new buildings. It develops where the insulation system is damaged, ineffective or missing.

It is recognised by the presence of damp and/or salt efflorescence stains at varying heights on both facades and the inner walls of the building, resulting in deterioration and damage to the plaster and walls themselves.

Rising damp on the wall in contact with the air evaporates, creating plaster deterioration, humidity in the room, formation of mould and a higher cost for heating the premises.

Thanks to ISOBELL, it is possible to take quickly measures against the effects of rising damp.

ISOBELL is the ideal solution when you deal with non-planar surfaces, particular geometric features to be preserved, sharp angles or corners, ledges, as well as limitations in the minimal amount of space available that could influence the thickness of the material to be installed.

There are several, and several buildings all around the world with these restrictions. Currently no flexible solutions are available that can at the same time restore a damaged surface (e.g. when micro-cracks appear) and provide a certain amount of energy efficiency (we made a simulation of the possible benefit in energy consumption, and up to 8% less in energy demand can be achieved) at a sustainable cost.

ISOBELL offers several advantages for your house compared to similar alternative solutions currently available in the market. Moreover, these solutions often suffer on exterior applications and impacts and are limited in absorbing deformations.


Current alternatives offered by the market are not easily comparable to ISOBELL, which isn’t limited to thermal insulation only. The base idea of the product is not only to provide a mean of increasing energy efficiency and internal comfort but in first place to develop a multifunctional material useful to restore damaged building surfaces, interior as well as exterior, thanks to its ability to absorb underlying deformations and micro-cracks transmitted through the wall to the outer surface.


ISOBELL is available in two formats, and it is suitable for every need. ISOBELL in pre-shaped sheets is ideal for complex surfaces, rich in decorative details, or in case of limited square footages. The standard format is 100 × 95 cm. Creating different sizes on request is possible. For the product application on entire walls, it is advisable to use ISOBELL in 15 meters rolls, which can be laid from above.
