Double Bank Weather Louvre Type DBL

If elevated levels of rain protection, combined with a conventional louvre appearance are required, look no further than HVC Series DBL Double Bank Louvres.

The double layer chevron blade arrangement also brings a non-vision property, useful where line of sight through the louvre needs to be blocked.

  • Elevated rain rejection in comparison to Series WL standard weather louvres
  • Chevron blade design blocks line of sight
  • Corrosion resistant aluminium construction
  • Powder coating to a full range of RAL and BS colours available

Intended for any installation where elevated levels of rain rejection are required in comparison to Series WL standard weather louvres.

For higher, certified levels of rain rejection, please search for Series HPL80 ultra high performance weather louvres.


Comprising two banks of either WL50 or WL75 blades, Series DBL louvres are available with either a regular or inverted blade layout to suit the requirements of the installation; and being manufactured from extruded aluminium throughout, high levels of corrosion resistance are assured.

Aesthetically, from the front double bank louvres look exactly the same as standard weather louvres. This enables the use of both single and double bank louvres in the same installtion, with no need to worry about whether the two will contrast each others appearance.

Available with rear mounted volume control dampers or backdraught shutters, bird or insect mesh, and in a full range of RAL or BS polyester powder coated finishes, HVC can make your Series DBL Double Bank Louvre to your exact requirements.
