Modern construction using higher levels of thermal insulation requires increased levels of ventilation within the building fabric to prevent the build-up of moisture and condensation. The increase in U-value requirements from 0.45 to 0.25 W/m2K for floors and from 0.45 to 0.35 W/m2K for walls in the revised Building Regulations Part L has heightened the importance of ventilation.With the increasing awareness of hazardous subsoil gases such as radon and methane the need for underfloor ventilation has become even more apparent. Glidevale have a range of underfloor through-wall and cavity wall ventilation products which meet the regulatory requirements and provide protection against driving rain birds rodents and large insects.
