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.
