Mono-pitched Rooflight

 

Arguably the most universally used system for closing and providing a glazed cover. Mono-pitches have been effectively used for covered walkways, large scale
conservatory areas through to major atria on prestigious buildings. One of the
benefits of mono-pitch design is that it as 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
is equally at home when used to create an area of vertical glazing.

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

They may be glazed with a range of advanced glasses and high specification
polycarbonate options—from solid single glazed, for canopies and unheated spaces,
to multiwall structured or triple glazed with exceptional thermal performance for
Part ‘L’ compliance.

All metal parts can be mill finish for economy or, alternatively, colour coated with polyester powder, PVF2 or anodised.

 

Illustrated here are details from a mono-pitched installation, designed and constructed with 15° geometry several such rooflights are arranged around a newly constructed building, introducing daylight light to areas that would otherwise lack the benefit of natural light.

 

Such details are indicative only—project specific designs and details are produced for each project engineered by Xtralite.
