Mono-Pitched Rooflight

Perhaps the most universally used system for closing and providing a glazed cover, Mono-pitches have been effectively used to create covered walkways and large scale conservatory areas all the way to major atria on prestigious buildings.

One of the principle benefits of the mono-pitch design is that it is rigidly constrained by the need for a level, orthogonal structure onto which it mounts. Capable of receiving accessories like smoke or natural ventilation modules, access hatches and doors, the mono-pitch can also be used to create an area of vertical glazing.

The usual geometry for these roofligths would be 30°, although 45° is not uncommon. The limits for slope ranges from 10° up to near vertical.

  • Can be glazed in a range of polycarbonate and glass options - from solid single skin for canopies and unheated spaces, lumira and glass, to multi-wall structured giving exceptional thermal performance for Part ‘L’ compliance.
  • Metal parts can also be colour coated with polyester powders, PVF2 or anodised.
