Unfortunately this is a misconception in the skylight industry as OSHA does not approve products they only provide guidance and standards. This would mean no skylight regardless of manufacturer could be considered "OSHA Approved".  VELUX tests many products according to the most recent OSHA standards, which for skylights no longer includes a weight threshold to be met. By providing the amount of weight the skylight can withstand building owners and contractors can make informed decisions about compliance with OSHA.

Fasteners are not included but they can be purchased at an additional cost. Please contact your local Commercial Rep for more information. 

Insect screens are not available for VELUX Modular Skylights at this time.

The VELUX Commercial Team can provide guidance on which skylight systems will need structural calculations. For assistance in or questions please contact your local Commercial Rep or email commercialestimating.us@velux.com.

Yes structural or metal framed skylights are available pre-glazed in certain sizes and configurations. Contact your local Commercial Rep to discuss whether this would be an option for your project. 

Yes this configuration would be possible as a custom request. Please inform the Commercial Team at time of quote request.

VELUX can assist with identifying the proper information such as exterior curb dimensions, interior skylight dimensions, rise, and mount needed for a specific project. If modifications to a curb are the recommended solution the Commercial Team can assist with custom product options.

In most cases sourcing a curb from the metal panel manufacturer is the simplest solution. However VELUX can assist with identifying the proper information such as metal panel style, dimension between ribs, rib rise, etc. needed to quote a curb to match the roof. Please contact your Commercial Rep for more information.

Modules are pre-wired with a 24vdc line in a panel under the flashing. The low voltage line can wire to a switch or integrated into a control system with the design by your engineer. You can request an electrical wiring diagram from VELUX Commercial which can be used by your electrical engineer and/or contractor. 

The building blue prints should list what fusible link temperature is required, which is typically always one setting higher than the sprinkler system fuse. Please contact your Commercial Rep for more information.   

VELUX always recommends checking with local fire code officials to ensure proper smoke vent coverage. The typical rule of thumb is 1% of the roof envelope for most applications or 2% if there is high pile storage or more flammable enviroment. In projects where smoke vents are being replace a permit might be needed due to the life safety factor which smoke vents fall in. Please contact your Commercial Rep for more information.

The VELUX Dynamic Dome produces up to 20% more light than competitive skylights due to the profile of the dome and the smooth outer lens, both of which lead to more usable light into the building. Please contact your local Commercial Rep for more information. 

Yes! Reference the install guides for more details or consult with your local Commercial Rep. 

Yes! Maintenance guides are available for many of our commercial products. For more information please contact your local Commercial Rep.

Diameters for commercial applications are typically 22" and 14". For larger sizes a standard unit skylight would be much more cost efficient. Please contact your local Commercial Rep for more information. 

ICD stands for "Inside curb dimension", or what some consider the rough opening of the skylight, and OCD stands for "outside curb dimension". 

VLT, or Visible Light Transmittance, is the measure of light that is transmitted through a skylight or window. A high VLT is important as it indicates how much light is transmitted from the outside of the building to the inside through the skylight. Since the value of daylighting is in delivering the most usable light, you always want to achieve the highest VLT while meeting local code requirements for thermal transmittance.

SHGC is the measure of solar radiation emmitted through a skylight or window. The lower the SHGC the less solar heat is transmitted through the skylight or window. Having a lower SHGC can be beneficial for thermal reasons however VLT will be adversely impacted as well, making the skylight less effective at transmitting VLT. Consult your local Commercial Rep determine to optimal balance between SHGC and VLT for your project.

There are two models that fall into the single pitch category: the Longlight Series with flashing designed for a 5 to 25 degree pitch, and a Northlight series with flashing designed for a 25 to 90 degree pitch. The Step Down Series and the Longlight Atrium Series ( 5-25 degrees) can also fit into this category. Please review the pre-engineered flashing design to make sure it matches your design intent.

The ICC # for the VELUX Dynamic Dome is ESR-4108.

The glazing space in VELUX Dynamic Dome allows condensation to escape from in between domes instead of being trapped. While most moisture will evaporate over time heavy condensation buildup could cause other complications such as seal degradation and mold growth. Please contact your local Commercial Rep for more information. 

The default deflection for skylights with glass glazing is L/175 for rafter lengths up to 13'-6" and L/240+.25 for rafter lengths 13'-6" or greater, with a maximum deflection of 3/4" for an individual lite of glass. It is recommended to review the design conditions with your Commercial Rep prior to finalizing the skylight design.

The default glazing for the Dynamic Dome LuxGuard series is clear smooth poly over high white prismatic poly. Several other options are also available. Please contact your local Commercial Rep for more information. 

The haze rating, or amount of diffusion, on the VELUX Dynamic Dome is 100%. This means the daylight passing through the dome is spread to the most efficient level possible in the building. Please contact your local Commercial Rep for more information. 

Standard size unit skylights can be shipped in less than 10 days for quantities up to 150. For higher quantities or custom sizes, the lead time could be 14+ days depending on complexity and total quantity. Please contact your Commercial Rep for project specific lead times.

The thickness of the curb / sub construction should be 8 -1/4" in order to acommodate the selected attachment method and to cloak the condensation gutters. More information on can be found in the VMS Subconstruction document available on the webiste or your Commercial Rep. 

The standard fastner for the VELUX Dynamic Dome is 1 3/4" #8 stainless steel with rubber washer.

VELUX uses an open cell foam as the glazing spacer in the Dynamic Dome, which allows for moisture to move into the condensation gutters instead of being trapped between the lenses. Please contact your local Commercial Rep for more information. 

VELUX Commercial offers a full range of daylighting products, including unit, metal framed, tubular and structural skylights, to fit your needs. Please contact your local Commercial Rep for more information or to discuss which products may be applicable for your project.

VELUX offers a variety of fall protection options for use with unit skylights including exterior and interior screens as well as burglar bars. Please contact your local Commercial Rep for more information.

The Velux Modular Skylight Series is the only commercial skylight available with ventilation at this time. It is best to have a minimum of 3% of your modules ventilated. Please contact your local Commercial Rep for more information. 

VELUX glass skylights have long been used in Commercial applications such as schools and office buildings. In the early 2000's VELUX moved into Commercial skylight production by acquiring a unit skylight manufacturer. Then in 2016 VELUX launched the Dynamic Dome, a high performance unit skylight which outperformed the competition by deliverying more light for more hours a day. In 2018 VELUX acquired Wasco Products, a market leader in structural glass skylights, to add even more options to the product portfolio.

The 10mm double wall multi-wall panel is typical for a laylight in energy efficient unit skylights like the EcoSky3, or as a laylight in a barrel vault skylight. To add to the thermal insulating value this panel can be filled with Lumira Aerogel. Please contact your Commercial Rep for more information. 

The 16mm triple wall panel is typically used as a second glazed layer in a skylight for added insulation. Please contact your Commercial Rep for more information.  

The 25mm triple wall panel is the most versatile. It's thickness is close to glass glazing and can be used in a single panel or doubled with a 16mm panel for additional thermal insulation. This panel is used for skylight and canopy applications. Please contact your Commercial Rep for more information.  

The 40 mm seven wall tongue and groove panel is used for vertical wall applications. Please contact your Commercial Rep for more information. 

Standard solutions do not require the structural reinforcement of an I-beams. The use of an I-beam would be needed in solutions where additional support is necessary due the weight and/or thrust of the modules, such as low slope designs, atriums and step configurations. I-beams are not included in the VMS system and will need to be sourced seprately after review by a Structural Engineer. Please contact your Commerial Rep for more information.

Measuring the finished outside curb dimension is the only information needed for VELUX to quote a replacement dome to fit an existing curb.

If the area is prone to snowfall, you should be concerned about snow drift on a skylight when it is within 20 feet from a wall or if a skylight is on a taller portion of a building. VELUX can assist with calculating this information based on project specifics and climate. Please contact your local Commercial Rep for more information. 

The VELUX Dynamic Dome unit skylight with Luxguard and Luxguard Plus glazing are available with a FM listing. Please contact your local Commercial Rep for more information. 

The VELUX Dynamic Dome with LuxGuard and LuxGuard Plus glazing are best at resisting hail breakage and carry hail warranties. The structural skylights, LumiWall 40, and canopy systems are also best at resisting hail breakage but do not carry hail warranties. Other products such as VELUX Modular Skylight Series and the Pinnacle Structural Skylights with glass offer impact resistance, due to thinkness of glass glazing, though they do not have any hail warranties associated.

VELUX can assist you in determining which commercial product will best fit the climate zone for your project. In order for VELUX to assist you, it is recommended to know the ground snow level in PSF. Please contact your local Commercial Rep for more information. 

VELUX prides itself on third party validated testing to support many different design solutions paired with different thermal values. The EcoSky3 unit skylight, VMS in double or triple low e glazing, the Horizon multiwall series with lumira gel infill meet the strictest thermal values across all zones. Please consult your Commercial Rep for the best solution to match current codes and climate zones.  

Diffusion indicates how well light is spread as it comes through the skylight. A high percentage of diffusion is important as it means the natural light is spread more evenly throughout the building underneath the skylight, as opposed to directional light that can be both glary and hot. Since quality of light is just as if not more important than quantity of light, always select a skylight with an appriopriate amount of diffusion based on the space it will be installed.
