Lime-based undercoat for durable, breathable façades

KB13 417 is a white, lime-based organic undercoat designed for external thermal insulation systems. It provides a durable base coat prior to the application of finishing plasters, whilst maintaining excellent water vapour permeability. Suitable for both new-build and renovation projects, it offers a high-performance solution for the long-term preparation of façades.

Our ITE expert’s opinion

This lime-based undercoat is particularly suitable for old or uneven surfaces, where a conventional cement-based undercoat may cause stress. Its breathability makes it a suitable choice for the renovation of traditional buildings.

External thermal insulation mesh, 4×4 mesh, 160 g/m², CSTB-certified – 50 m² roll

The ITE mesh, with a 4×4 mm mesh size and a weight of 160 g/m², is a CSTB-certified fibreglass reinforcement designed to strengthen the base layer of external thermal insulation systems. Sold in rolls measuring 1,000 mm x 50 m (50 m²), it offers a tighter mesh and a higher weight per square metre than the standard mesh.

Its CSTB certification makes it the preferred solution for external thermal insulation systems requiring reinforced mesh, particularly in areas most exposed to mechanical stress.
