Redstone Clima Redboard Pro (previously known as Calsitherm Climate Board) is a high-performance internal wall insulation solution designed for solid walls, providing superior thermal regulation alongside unbeatable moisture management. Its unique properties make it ideal for energy-efficient buildings that require insulation, excellent moisture management, mould prevention and breathability. Redstone Clima Redboard Pro has an A1 non-combustible fire rating which means it is also suitable for use in tall buildings.
As an internal wall insulation solution, Redstone Clima Redboard Pro helps maintain a comfortable indoor temperature by preventing heat loss during the winter and reducing overheating in the summer. Its outstanding moisture management capabilities ensure that even large amounts of moisture can be allowed to evaporate harmlessly into the room, preventing moisture accumulation that can lead to damp and mould (providing any maintenance issues or leaks have been addressed prior to installation). This makes it particularly valuable for historic buildings and renovations, where preserving the integrity of original materials is crucial.
The Redstone Clima Redboard Pro system includes all necessary components: Levelling plaster (Diasen Diathonite Thermactive.037 or Lime Green Duro), Redstone adhesive for bonding the insulation boards, Redstone Redboard Pro (the insulation board), and Redstone Luno finishing plaster with embedded Redstone Mesh. This complete system ensures a cohesive approach to internal wall insulation for solid walls.
Made from natural, breathable materials, Redstone Clima Redboard Pro offers not only superior thermal performance but also helps improve indoor air quality by reducing pollutants and harmful off-gassing often associated with synthetic insulation products. It is an ideal choice for those seeking to enhance their building's energy performance and create a healthier, more comfortable indoor environment, particularly in situations where moisture levels are particularly high or where an A1 fire-rated solution is required.
About Redstone Clima Redboard Pro
Redstone Clima Redboard Pro is an innovative internal wall insulation material that combines high thermal performance with moisture regulation. This ensures that buildings are not only energy-efficient but also remain healthy and dry.
When applied to internal walls, Redstone Clima Redboard Pro helps regulate the indoor temperature by reducing heat loss during winter and limiting the need for cooling in the summer. Its moisture-regulating properties reduce the risk of condensation, helping to prevent the accumulation of damp and growth of mould, which can damage the building structure.
The natural, breathable composition of Redstone Clima Redboard Pro makes it an excellent choice for eco-friendly, sustainable buildings. Its combination of superior insulation and environmental integrity ensures lasting performance with minimal impact on the environment.
As with any Internal Wall Insulation system, the wall must have any sources of water infiltration from ground sources, poor pointing, water leaks or poorly maintained gutters/pipes etc made good before installing the insulation. Refer to our guidance document: “How to prepare walls for Internal Wall Insulation” for full details.
Redstone Clima Redboard Pro offers exceptional internal wall insulation for solid walls, improving thermal comfort and reducing energy consumption. Its breathable and highly capillary active nature effectively manages moisture, preventing the build-up of damp and mould. Suitable for both new builds and retrofits, it ensures optimal heat retention in the winter and cooling in the summer, contributing to a healthier and more comfortable indoor environment. The natural, eco-friendly composition of Redstone Clima Redboard Pro enhances air quality while offering durable, long-lasting insulation. It’s the perfect solution for creating energy-efficient, moisture-regulated buildings with reduced energy costs and improved sustainability.
