New High Performance Louvre from HVC

HVC has introduced a new Class A ultra high performance weather louvre. With never before seen performance levels for a horizontally bladed weather louvre, and the result of intensive research and development conducted over several years, the new HPL80 model represents a huge step forward in performance over their old HPL75 model louvre.

The new louvre has been independently tested by BSRIA against BS EN 13030:2001 and confirmed to provide the following performance:

  • With insect mesh: Class A2 performance up to 4 m/s (airflow coefficient 0.329)
  • With bird mesh: Class A2 performance up to 2.5 m/s (airflow coefficient 0.345)

These performance levels yield multiple benefits, from initial cost savings due to smaller units being capable of performing the same job as larger, worse performing units, to ongoing cost savings due to the reduced energy consumption of fans which can now be run at lower speeds with the same effect for example.
