UdiIN RECO® SYSTEM
A new interior insulation system
specially designed for uneven surfaces
Application
| The UdiIN RECO® SYSTEM is the alternative solution to vapour-proof interior insulation. It enables the problem-free installation of interior insulation for the retrofit of existing buildings. The external appearance of the building and the type of wall construction are unimportant. Regardless of whether the walls are slim, half-timbered structures, double-skin brickwork or heavy natural stone, this system is suitable for all types. Contrary to foam or mineral-fibre insulation boards, the accumulated condensation is absorbed by the UdiIN RECO® SYSTEM and, thanks to its quick-drying properties, is then transported into the room air or through the capillary effect to the outside of the building. | ![]() |
| Benefits of this system: | |
Properties
• Adjustable up to +/- 20 mm
• Automatic levelling compensation
• For uneven internal walls
• Available 80 to 200 mm insulation thicknesses
• A tight surface fit
• No additional moisture loading as a mortar bed or filler layer is not required
• No need for complicated substructures/mounting structures
• Can be screwed and adjusted without any fuss
• No moist areas due to the systems open diffusion and active capillary properties
• Quick drying
• Universally applicable on both thick and thin walls
• Resonance-free sound proofing
• Water vapour regulating with the application of our mineral vapour retarder
• No need for insulation wedges or corner insulation boards
• The surface of the mineral vapour retarder serves as a base layer for plasters and paints
• Patent protected

| The boards are installed and affixed using our innovative adjustable fixings which are already successfully used in the UdiRECO® SYSTEM for exterior applications. The system can be easily adjusted, fixing for fixing, using a spirit level or laser. | Coating the boards with our water vapour regulating Udi MULTIGRUND® provides extra protection against construction damage and forms the basis for a permanently dry, smooth, crack-free, paintable surface. | All sorts of materials can be applied to the surface as finishing coats. Plasters, paints, wallpapers or other coatings are all possible. Natural loam plasters or mineral-based paints from the UNGER-DIFFUTHERM range are particularly well suited. | ||
