Questions On Skylights

Yes, insect screens are included with venting skylights and are available separately for all of our roof windows. To ensure that you receive the correct new or replacement screen for your window, please obtain the serial number from that unit.

Clouding or fogging of an insulating glass unit occurs when there is a break in the inner seal between the glass panes. As a result condensation forms between the two panes. Units manufactured after January 1, 2000 have a 20 year seal warranty. If you encounter a problem with the seal of your glass, obtain the serial number from the roof window or skylight and contact VELUX. We will be glad to help you determine if your product warranty is still in effect, and what actions can be taken to correct the issue with the seal.

No. It would be necessary to replace the fixed skylight with a ventilating unit.

VELUX can make some custom sized skylights that vary from the standard sizes shown in the price guide. We can also make many custom sizes for the FCM curb mounted skylight.

All current skylight and roof window units are a neutral grey color that blends well with most roofing materials. However, copper cladding is available upon request for deck mounted skylights and select roof windows.

A Roof Window is a unit designed for installation “in-reach”. The Roof Window sash can be pivoted so the homeowner can clean the exterior pane of glass from inside the home. Some larger Roof Window models meet building code requirements for egress (emergency escape). Many times Roof Windows are installed in attics being used as living space. Skylights, on the other hand, are usually installed in “out-of-reach” applications.

Each of our flashing kits are engineered with specific pitch requirements. The roof pitch is important because it ensures that the roof has the proper slope to effectively drain water off of both the flashing and the skylight. The roof pitch and the roofing material used are both important in determining the type of flashing needed.

Questions On Sun Tunnel™

A precise answer depends on many factors including the roof orientation (i.e. South is always best), tunnel length, tunnel angles, time of day, season of the year, etc. However, generally the 10 and 14-inch diameter TGR and TMR units are best for lighting up bathrooms, halls, walk-in closets and areas up to 10′ x 10′. The 22-inch diameter TCR model is perfect for lighting larger areas. The same size rigid tunnel will always transmit more light than a flexible tunnel of the same size, length and configuration.

Clouding or fogging of an insulating glass unit occurs when there is a break in the inner seal between the glass panes. As a result condensation forms between the two panes.

Rigid tunnel VELUX SUN TUNNEL™ skylights are available in three different sizes. In all there are three different sizes:

  • 10-inch diameter (TGR and TMR)
  • 14-inch diameter fits between 16″ on center framing (TGR and TMR)
  • 22-inch diameter fits between 24″ on center framing (TCR low-slope units only)

Yes! The TGR and TMR are 2010 ENERGY STAR® qualified.

The flexible sun tunnel is the simplest and fastest way to install tubular devices available. It easily bends around attic obstructions like pipes and wires making alignment between the roof and ceiling simple.

The dome, flashing, tunnel, hardware and everything needed for a complete roof-to-ceiling installation (including step-by-step instructions and labels) are all included. There are no tools included in the kit.

Our VELUX SUN TUNNEL™ skylights come with a ten year warranty. For a complete overview of all product warranties, visit our Warranty Info section.

TGR and TMR are designed for asphalt shingles and wooden shingles up to 5/16″ (8 mm) thick and roof pitches between 14°- 60° (3:12 – 20:12). The tile kits ZTG and ZTM (available separately), expand the use of TGR and TMR to include profiled roofing materials (tiles) with maximum 1 ¾” (45 mm) profile height.

Winter time means that lots of us get stuck indoors at home and work. Studies show that natural, full-spectrum sunlight greatly contributes to increased productivity in the workplace and to an overall feeling of well-being. Sunlight deprivation can lead to a condition that experts call “Seasonal Affective Disorder,” also known as S.A.D. or the winter blahs. By bringing light from the sun into your house, or home office, a VELUX SUN TUNNEL™ skylight can help you beat the winter blahs.
