Fibre-Reinforced, Super-Insulating Aerogel Lime Plaster system – Base coat for thermal insulation

The system consists of two perfectly compatible coats:

  • Coat 1 – Thermal lime base coat with a variable thickness tailored to the required U-value and a granulation of 1–1.2 mm, providing thermal mass and an efficient insulating substrate.

  • Coat 2 – Lime thermal finishing coat, featuring a granulation of 0.5–0.7 mm, provides excellent heat reflectivity, minimising heat loss and enhancing year-round indoor comfort.

developed to deliver exceptional thermal performance in a thin, fully breathable layer. Natural, durable, and highly efficient, it offers measurable energy savings while providing long-term protection against mould and fungal growth.

This two-component plastering system improves the insulation and thermal characteristics of all types of masonry — from traditional solid walls to modern substrates — including walls, pillars, and door or window reveals. It performs equally well in historic restorations and modern construction, offering a sustainable approach to energy efficiency that preserves both breathability and the building’s original appearance.

This product is manufactured to order with an estimated lead time of approximately 3 weeks. 

Description

Owing to its high insulation capacity in minimal thickness, RasoThermo is especially suited to listed and period properties, where conserving historic detail and interior space is essential. It enables specifiers and conservation professionals to enhance thermal comfort discreetly, maintaining the authenticity of the structure.

Suitable for both internal and external use across residential and commercial projects, RasoThermo Aerogel can also be applied to ceilings, floors, reveals, curved walls, etc. A 5–10 mm coating applied around beams and pillars effectively reduces thermal bridging and eliminates surface condensation.
