Skylights and sun tunnels are both energy efficient ways to
invite more natural light into your home. No matter the option you choose, each
will
create a bright, sun-filled space that is sure to boost your mood and provide
your body with much-needed vitamin D.
Skylights are acrylic, glass or polycarbonate windows set
into the roof of your home. They are usually rectangular and consist of three
main components, including:
- Glazing –
the clear window
- Frame –
sets
the window into the roof
- Flashing
–
helps prevent leaks
Skylights can range in size from 12- by 12-inch squares to
larger rectangular areas, though they should never exceed 15 percent of the
targeted room’s square footage.
Sun tunnels, also
known as solar tubes, are an acrylic or polycarbonate dome installed on the
roof to catch the sun’s rays. The sunlight is then reflected down a rigid or
flexible sheet metal tube in the attic before shining on the diffusing lens in
the room’s ceiling. These are typically 10 to 14 inches in diameter but can be
larger.
Sun
tunnel installation
can take as little as two hours and no more than half a
day. The dome is installed on the roof with proper flashing and the tube is
extended from the dome to the room’s ceiling. The light diffuser is then set
into the ceiling with minimal interior finishing work needed.
Skylight installation is more time-consuming because it
requires more carpentry work than sun tunnel installation. One rafter will have
to be cut for most skylight sizes, requiring the rafters around it to be
doubled.
Even without cutting, the process requires careful work
finishing the inside of the room and installing flashing to prevent leaks.
Unlike sun tunnels, skylights add to a room’s appearance by
opening the ceiling for a breathtaking view of the outdoors. In some cases,
adding a skylight may add to a home’s resale value. Skylights can be vented or
shaded and filtered to partially block UV rays.
Skylights can be gorgeous additions to any home, but there
are a few things to keep in mind. Because of their size and appearance,
skylights need more interior finishing and are more expensive to purchase and
install. Also, skylights are less energy efficient, allow more heat gain and
are commonly associated with condensation and leakage problems – unless
installed by experienced professionals.
Sun tunnels are easier to install than skylights because
they require little interior finishing. They are also less expensive overall.
Sun tunnels are more energy efficient than skylights and in some cases may
qualify the homeowner for an energy tax deduction. They also block potentially
damaging UV rays and cause less heat gain.
While they have a long list of benefits, some are prone to
forming water condensation inside the tube, don’t offer outdoor views and
likely won’t boost your home’s resale value.
If you’d like to bring more natural light into your home,
skylights and sun tunnels are excellent, energy-efficient options.
