Star Renovations Hydrophobic Insulation Crème has been tested and certified to ISO standard. The product penetrates deeply into the substrate, creating an invisible insulation barrier that reduces water absorption by more than 95%. HYDROPHOBIC Insulation Crème has been tested according to EN ISO 15148:2002, demonstrating its hydrothermal performance on concrete, mortar, brick, and sandstone.
Damp walls = Thermal bridges
Damp walls = Thermal bridges
Damp walls = Thermal bridges
If the pores of a wall collect moisture, more heat is transferred than it would be possible if the cavities were filled with air. In conclusion, the thermal conductivity of the wall decreases enormously with dampness. Tests have shown that a damp content of 5% in a plain brick wall, for example, can lower the insulation performance by up to 50%, especially where cavity wall insulation has been installed. Consider that porous building materials, such as natural stone, brick and solid brick, to name a few, normally have good insulating properties. They have air-filled cavities, which offer low thermal conductivity. BUT ONLY WHEN THEY ARE DRY!

Damp walls = Thermal bridges
The masonry is able to breathe and will be permeable to water vapour whilst allowing air and moisture to pass through from one side to the other. A breathing masonry will improve the thermal conductivity and insulation properties. Consider that just a 5% content of damp in cavity wall insulation or other building materials can lower the thermal resistance by up to 50%.
