Introduction
VELUX modular skylights are sash-frame constructed single skylights with a high-insulating glazing unit. The modules are available as fixed and venting skylights. All individual skylights are delivered as prefabricated modules with dedicated factory finished flashings to ensure superior watertightness in every available solution.
VELUX modular skylights are CE-marked in accordance with the harmonized standard EN 14351-1:2006+A1:2010 Windows and doors.
In addition the skylight modules have been tested and approved in accordance to EN 12101-2:2003 - Smoke and heat control systems Part 2: Specification for natural smoke and heat exhaust ventila-tors. This means that VELUX modular skylights with ventilation capabilities may also be used as Natural Smoke and Heat Exhaust Ventilators (NSHEV).
This technical handbook for VELUX modular skylights describes the product characteristics and performance of the skylight module together with sunscreening and control system. For real life case studies and inspiration, please refer to velux.co.uk/modularskylights

HFC Fixed skylight module
VELUX modular skylights are available as fixed and venting mod-ules. Due to a hidden chain actuator, the fixed and venting skylight modules appear to be visually identical in closed position.
Venting modules are top-hung and can be used for comfort ventilation, and in addition, a number of sizes are also approved for smoke ventilation according to NSHEV EN 12101-2:2003.
Functions & Sizes
HVC Motorized comfort venting skylight moduleOpening up to 410 mm
HVC Motorized smoke venting skylight moduleOpening up to 700 mm in less than 60 seconds
CE marked VELUX modular skylights can be used in any building where the national, local and individual building requirements allow the use of skylight modules. Given the aesthetics and advanced per-formance of the products, VELUX modular skylights are commonly used in heated buildings and primarily in projects that support light
commercial interests, e.g. hospitals, schools, shopping centres, of-fices, museums etc. However all buildings that have a suitable struc-ture, and which are large enough to host an installation, will support VELUX modular skylights.

How to measure the modules
Width and height of the modules are determined by the exterior W and H dimensions of the frame not the measurements of the cladding, flashing or brackets.

The main structural profiles of VELUX modular skylights consist of pultruded composite, containing approximately 80% continuous fi-breglass treads and 20% two-component polyurethane resin.
The composite guarantees high heat insulating performance (graph 1) and thermal stability (graph 2) as well as excellent profile shifti-ness (graph 3) and strength (graph 4). In combination, the charac-teristics of the VELUX composite gives the slim profiles self-suppor- ting strength and an ability to support installations of considerable
size. In addition the material is maintenance-free, non-corrosive and electrical non-conductive.
In combination with low-energy glazing units the VELUX modular skylights are able to achieve one of the lowest overall U-values for frame and glazing assembly within the skylight market. The inner surface is treated with white paint as standard. Other colours are available to special order.

Thermal conductivity (W/mk) A low score means high insulation performance
A low score means high thermal stability
Profiles used for VELUX modular skylights consist of an extremely low-conductive pultruded fibreglass and polyurethane composite resulting in high insulation performance.

Linear expansion coefficient (10-6 m/m K)
Whereas traditional skylight materials are bound to fluctuations in form due to thermal changes, the compos-ite of VELUX modular skylights will maintain its dimen-sional properties, ensuring tightness of joints and pro-longing the expected lifetime of the application.
