How to achieve a good insulating lining?According to the French RT Existant par Élément energy efficiency standard, overall the wall must have a R value of 2 m2. K/W with R Total = R Existant + Tradical® insulation.Example for a 50 cm rubble stone or brick wall, with λ = 1.7 W/m.k (1)

Hygrothermal renders

- On solid ground floors thanks to its thermal performance ratings.- On upper storey floors owing to its low density and its

thermal and soundproofing performance ratings

- Ultra-light.- Levelling with thickness variations corrected as the

work progresses (minimum thickness 7 cm).- Flexibility of the hemp/lime composite for perfectly

adaptation to possible structural deformations.- Variety of finishes: wood flooring, embedded terracotta

tiles, ceramic tiles laid with adhesive, etc.

- In sloping parts prior to installing the roofing.- In the depth of attic floors.- On the floors of unused attic spaces.

- Ultra-light, ideal for existing frameworks.- No risk of damage from rodents.- Easy to apply and adapt to existing shapes.- No painstaking cuts that lead to thermal bridges.- Immediately protected from water as the roofing can be

laid as work progresses.- Suitable for all kinds of frameworks and roof slopes.

- Interior and Exterior use on all types of mineral substrates.

- Eliminates the ‘cold wall effect’- Ideal for renovating exteriors by building an insulating

wall.- No risk of dew point thanks to a tight bond with the

original wall, with no air layer.- Reduce the number of work phases.- Easy to apply and adapts to the geometry of the existing

walls as the wok progresses. - Variety of finishes possible: from the rustic hemp look

through to smoother contemporary finishes.- For colouring options, see the Tradical® Premium

system.
