Important installation requirements
Roof pitch
FS is designed for roof pitches 14° – 85° (3:12 – 137:12). In case of roof
pitches below 14° (3:12), please contact your VELUX sales company for
installation guidelines.
Importance of proper installation
Satisfactory product performance depends on proper installation.
The seller accepts no responsibility whatsoever for the failure of an
installer to install VELUX ®roof windows and skylights in accordance with
these installation instructions. Although VELUX roof windows and skylights are
designed and manufactured to the highest standards, severe climatic exposure,
as well as adverse indoor conditions(ie high humidity), may produce
temperature conditions that exceed product performance standards. In these
cases, special preventive measures may be necessary. Seller eserves the right
to implement product changes for improvement without prior notification.
Sunscreening accessories
Refer to instructions for accessory type in a question or contact your VELUX
sales company for further information.
Vapor barrier
Where a vapor barrier is part of the roof construction, this barrier must
be extended and connected to the skylight finish groove.
Treatment of wooden frame
Most VELUX skylights are pre-painted white but the option exists to order
stain-grade skylights. These stain-grade skylights received a temporary
treatment against mold and mildew. Further treatment with wood stain, paint,
etc is necessary and can be done prior to installation or shortly after
installation. Care should be taken to ensure wood stain, paint, etc is not
applied to gaskets.
Consult local jurisdictions and authorities for recycling and proper
disposal of removed skylights and materials.
NOTICE
Skylights and interior surfaces in older homes may have been painted with
lead-based paint, and removal of the skylights may disturb this paint. Take
proper precautions to minimize exposure to dust and debris. For more
information on the proper removal of lead paint go to
www.epa.gov/lead.
Seller assumes no obligation whatsoever for the failure of an architect,
installer, or building owner to comply with all applicable laws, ordinances,
building codes, and safety requirements.
NOTICE
In rare circumstances, all-glass may be subject to unexpected and spontaneous
breakage due to imperfections in the glass that are undetectable during the
manufacturing and inspection process by the manufacturer of the glass and the
VELUX factory. Your VELUXsales company offers the choice of laminated or
tempered glass skylights. Laminated glass is a combination of two or more
glass sheets with one or more interlayers of plastic (PVB) or resin. In case
of breakage, the interlayer is designed to hold the fragments together.
Tempered glass does not contain an interlayer to hold the fragments together.
Instead, tempered glass is designed to break into small, pebble-like pieces.
When tempered glass breaks, pieces of glass come loose and may strike an
individual.
Consult local regulations and/or building material consultants to determine
which type of glass is right for you or if the laminated glass is required in
your application.
Important installation requirements for the USA and Canada
VELUX®series A21 skylights are designed and engineered to be installed with
VELUX flashing systems. VELUX flashing systems include VELUX adhesive
skylight underlayment in a quantity sufficient to install one skylight of the
size for which the flashing system was designed.
The VELUX “No Leak” installation warranty is based upon installation strictly
in accordance with VELUX deck or curbs mounted skylight and related deck or
curb mounted flashing installation instructions, which specify the use and
proper installation of the VELUX adhesive skylight underlayment packaged with
the flashing system.
If VELUX adhesive skylight underlayment is not used or is not properly
installed and a service issue occurs related to underlayment omission,
failure. or its proper installation as detailed in the VELUX deck or curb
mounted skylight and deck or curb mounted flashing installation instructions,
the VELUX “No Leak” installation warranty is void.
VELUX America LLC understands that there are other types of adhesive
underlayment that are of equal or higher quality than what is provided by
VELUX America LLC. However, VELUX America LLC cannot approve or validate that
any specific type of adhesive underlayment is better or worse. Thus. VELUX
America LLC places the risk of using an alternative adhesive underlayment onto
the specifier by stating that if the alternative underlayment becomes a
failure point for the skylight or flashing system even if installed according
to our instructions. then the VELUX No Leak” installation warranty cannot be
honored. Further, the alternative underlayment must not in any way obstruct,
alter or prevent the proper functioning of the complete skylight and flashing
installation, such as increasing the overall flashing system thickness beyond
prescribed dimensions.
VELUX America LLC affirms that if a high-quality alternative adhesive
underlayment installed per our instructions, does not fail but a leak occurs
in some other VELUX skylight or flashing component due to no cause from the
alternative underlayment then such a leak would be covered under the terms of
the VELUX No Leak” installation warranty.
clearance around installations
Maintain illustrated clearances between skylight frame and critical areas such
as valleys, ridges, slope changes, and roof-to- all intersections.
When installing skylights side by side within the span of 2½” – 12″ (65 mm –
300 mm), please refer to VELUX combi-flashing instructions.
Light shaft application
Cut rough opening according to the measurements in the chart.
Roof with battens:
Clear away battens from rough opening to allow for proper installation of
underlayment.

Remove existing roofing
underlayment around the rough opening as shown.
Mark
corners of the rough opening.
Roof with battens: Place 1½” (38 mm) wide battens around the rough opening. Batten thickness around rough opening should’ve equal to the thickness of battens used for roofing material.
Center skylight over properly cut and framed rough opening using alignment
notches as shown. Anchor skylight with 1¼” (30 mm) nails provided with the
skylight, one nail per pre-punched hole in the mounting flange. The carbon
steel nails are zinc-coated (double hot-dipped).
Note: Skylight FS cannot be rotated.

To ensure waterproofing, skylight frames should be completely wrapped in VELUX
adhesive skylight underlayment supplied with the flashing. This underlayment
must be applied before installing the flashing.
Note: If snow accumulation on the roof is likely, waterproofing is
achieved by installing a continuous self-adhesive waterproof membrane beneath
the roofing material and flashing material. VELUX adhesive skylight
underlayment around the skylight frame must be properly integrated with a
waterproof membrane on the roof decking.
Peel off the backing from VELUX adhesive skylight underlayment prior to
applying it to roof decking and skylight frame. Ensure that surfaces are
clean, dry, and free of debris.
Wrap the bottom frame and corners of the skylight with the underlayment and
create water-shedding laps over roofing underlayment.
Note: Lift up the rubber gasket while wrapping the bottom frame.
Note: Observe the measurements stated.
Wrap the
side frames and corners of the skylight with VELUX adhesive skylight
underlayment and create water-shedding laps over roofing underlayment.
Note: Observe the measurements stated.
Wrap the top
frame and corners of the skylight with VELUX adhesive skylight underlayment
and create a proper water-shedding lap.
To allow for proper drainage, interweave roofing underlayment as shown in 9a for new construction applications. For retrofit applications, interweave roofing underlayment as shown in 9b.
Installing VELUX adhesive skylight underlayment on the roof with battens: Refer to installation instructions included with VELUX adhesive skylight underlayment.
You are now ready to install the flashing. If the flashing is not to be installed immediately, reinstall cladding.
