What Is It Called When the Sun Giving Light to the Ceiling

Nigh of us would welcome more than natural light into our homes.  For one thing, it can reduce electricity utilise past lessening the demand to proceed lightbulbs running.  A brighter home likewise helps meliorate i's mood, and sunlight fifty-fifty provides physical health benefits by increasing the trunk'southward Vitamin D intake.  While windows allow sunlight into nearly homes during the day, for some it might non be plenty.  In many cases, sure interior rooms may not have any windows at all.  Thus, getting more natural calorie-free from above tin be a solution for making spaces brighter, completely irresolute the environment in a room.

That'due south where solar tubes and skylights come in.  While similar in purpose – that is, to provide more than daylight into a room – these roof and ceiling fixtures bring sunlight into the dwelling in very different ways.  Both take varying functions and characteristics, with accompanying pros and cons – everything from price and free energy efficiency to light control and aesthetics – and different homes may benefit from one more than the other.

How Exercise Solar Tubes and Skylights Work?

True to their name, solar tubes (also known every bit sun tunnels, sun tubes, or light tubes) are essentially tubes that tunnel sunlight into the home.  Instead of providing a direct line of sight to the sky, a solar tube volition capture light on the roof and disperse it into the room below.  That natural light is collected on the roof past a polycarbonate or acrylic dome meridian, and a series of mirrors then reflect it down to the bottom of a sheet metal tube.  At the bottom-end is a diffuser that looks much like a light fixture in the ceiling – just, instead of a lightbulb, natural calorie-free is dispersed throughout the room.  A tube can range in size, but they are generally on the minor side – almost ten inches in bore or more than.

Skylights, at their most basic level, are glass windows facing the sky.  They let rays of low-cal directly into the home without the need for whatever reflections, ordinarily through a rectangular pane of glass or other clear material that is visible in the ceiling.  The sunlight is not diffused similar with a solar tube, but is instead directly shone onto the floor expanse below.  The resulting shape and size of the low-cal'due south shine will be straight based on the shape and size of the skylight – while shifting across the room like a dull-moving spotlight, based on the sunday'due south position.

Comparing Skylights and Solar Tubes

Below is a comparing of solar tubes and skylights based on diverse factors.  The differences and pros and cons of each tin serve as a guide for anyone because which of these fixtures to install in their home.

Ease and Practicality

For an existing dwelling, a solar tube is not besides hard to install.  There are non many special considerations that need to be taken, although they may not be suitable for a roof with a very steep pitch.  Withal, most roofs with a moderate pitch can support 1, and different products and tunnel designs are recommended based on how the roof and ceiling are situated.  They can also be installed even when at that place is attic space between the roof and the room receiving the lite. Solar tube installation should by and large exist performed by contractors, but it is rather quick with setup, flashing, and finishing taking merely a couple of hours or half a day's work.

While skylight sizes vary, they are generally much bigger than a solar tube.  A significant corporeality of carpentry piece of work is required, with generally at least i rafter removed and all others needing reinforcement.  Flashing and finishing around the skylight is likewise vital, and solid, professional person work is needed to forbid any potential leaks.  In general, they can exist more of a hassle to install.

Advantage: Solar Tubes

Material and Installation Costs

Since adding a solar tube requires a relatively low-impact installation, with no major furnishings on the ceiling's drywall or the roof'due south framing, the cost of getting one put in is fairly low.  The cost of a tube itself can vary widely based in part on potential add-ons; for case, some products may accept an LED kit built into the diffuser so it can still supply light at night.  In the end, the typical cost of getting solar tubes is less than $1,000, including materials and a professional installation.  An added benefit is that many models are Free energy Star rated, and therefore eligible for a 26% tax credit.

The price of a skylight can also vary, in part based on add-ons such as UV-protection coatings.  The installation toll volition be largely based on the size and status of the roof, as well as the roofing material, but it is usually more intensive and costly than for a solar tube.  The total cost for materials and installation can run anywhere from a few hundred dollars to ii grand.

Advantage: Solar Tubes

Warm Weather Energy Efficiency

Solar tubes are especially advantageous in spaces that lack wall windows and do not get much natural daylight, as they will disperse natural light throughout an interior space.  During a sunny mean solar day, they tin can produce as much light equally multiple standard light bulbs, lessening the need for electricity.  Solar tubes also block heat free energy from getting in, and then they can do their job without raising the cost of air workout.

Skylights, on the other hand, provide more than concentrated light that can too rut upwards the home.  Unless certain measures or coatings are applied, heat energy is shone through too.  This tin can raise air conditioning costs during the summer months, when daylight is at its longest.  This is especially relevant in warmer climate areas.

Advantage: Solar Tubes

Common cold Weather condition Free energy Efficiency

While the lack of heat supplied to a room can exist dainty in the summer, this is less of an advantage during colder months.  The diffusion of complimentary sunlight for daylighting is still useful in the winter, though those well-lit hours are shorter.

The passive solar heating from a skylight tin be a major advantage in the wintertime.  The furnishings will be especially beneficial if a home is designed with passive heat gain in listen.  Sunlight can shine from the depression winter dominicus through a strategically-located, southern-facing skylight that maximizes its outcome to lower the cost of heating.  In colder climate areas, this can make a huge deviation for a dwelling house.

Advantage: Skylights

Low-cal Quality

Solar tubes control the type of light energy that gets through.  Specifically, the acrylic dome on the roof mostly blocks UV rays before they become into the tube itself.  This means that any light dispersed throughout the home will not cause sunburns or other adverse effects continued to harmful UV rays.

Skylights practice not usually block UV lite at the source in the manner that solar tubes do.  While a filter coating tin exist added to reduce the penetration, in that location will still exist some that gets through.  In addition to the potential long-term wellness effects, UV rays can cause furniture and decor to fade over time

Reward: Solar Tubes

Aesthetics

Since the output looks similar to a normal light fixture, and the rooftop dome being rather small, 1 could be forgiven for not noticing a solar tube is even there.  Solar tubes are subtle in that way, which some may capeesh.  Since the light they disperse is natural, this can provide a pleasing aura to a space.  What solar tubes lack, however, is a view to the outside.  And then fifty-fifty if the light provided is natural, there is no added do good of a pleasant view.

As an culling, skylights, of form, allow one to see directly outside and appreciate what'due south above and around them.  During the solar day, that can mean enjoying the heaven, trees, and any birds flying overhead.  Even at night, stargazers accept something to relish.  Moreover, some may as well find that a skylight makes the room feel a bit bigger.

Light Control

Even though the diffuser of a solar tube tin can resemble a lightbulb fixture, there is no on/off switch.  Once a tube is installed, the sun tunnels down and will consistently spread light each day.  It would be difficult to block or control that lighting, if needed.

A skylight may be customized with shades that tin can alternately block the sunlight or permit it through.   Some skylights tin fifty-fifty be vented, allowing one to open and close it like a window.

Reward: Skylights

Cleaning and Maintenance

Since the pinnacle of a solar tube is domed, it is difficult for droppings to stick to one.  In general, there is very little cleaning or maintenance needed as it is rare that anything – other than snowfall or other short-term accumulations – would obstruct the sunlight from getting in.  While solar tubes have a low propensity to leak, water condensation may develop on the inside of a tube, especially in high-humidity areas or spaces, such every bit laundry rooms.  This tin exist prevented past wrapping the tunnel with R-15 or R-xix insulation, while some models even offering a condensation release.  Ignoring whatsoever condensation tin can lead to mold issues or long-term damage of the solar tube.

Skylights are much more than probable to have debris, from bird poop to leaves and everything in between.  This can not only block the sunlight, only information technology can as well make the skylights much less pleasant to look through.  Droppings that collects over prolonged periods of time can also increase the likelihood of leaks, which are relatively mutual with skylights.  For this reason, they may require a fair amount of maintenance and cleaning.  Skylights also accumulate h2o condensation, generally inside the surface; prevention in this example usually requires treating the air with a dehumidifier.

Should You Become Solar Tubes or Skylights?

Solar tubes and skylights are natural lighting options with unique qualities, which may bring varying benefits depending on a home's condition, location, and a person'southward preferences.  Let's say, for example, Charlie wants more light in his house simply has a depression budget, a small roof, and lives in a moderate climate and in an area without much nature or dazzler to adore in the sky.  Michelle, on the other mitt, has plenty of money saved for home improvements for her large house in the cold north, which is situated in an area with beautiful scenery and birds flying all around.

When it comes to choosing whether to install a solar tube or skylights, Charlie and Michelle can use these points equally a guide.

To recap, solar tubes' benefits over skylights ordinarily include:

• Easier and more practical installation
• Lower cost for parts and installation
• Energy efficiency in warmer atmospheric condition
• A amend quality of light, without UV
• Less cleaning and maintenance required

While skylights take a few potential benefits of their own:

• Heat gains and energy efficiency in colder weather condition
• Better aesthetics
• More command over the light output

Based on these factors, for Charlie, a solar tube might be the mode to go.  The installation is affordable, and since he lives in the U.s.a. he can take reward of the tax credit for an Energy Star model.  The lack of heat gain volition create both advantages and disadvantages, depending on the flavour.  The low maintenance will also help keep costs depression and life a trivial chip easier.  And, since there is not much to encounter in the sky anyway, the lack of scenery compared to a skylight is no huge loss for him.

Michelle, alternatively, may prefer the more expensive skylights, as she's been looking to fundamentally change the look of her interior living spaces while likewise increasing her home's resale value.  She can have the skylights situated so they face the southern dominicus, helping her warm her business firm with passive solar heating in the winter.  Michelle may even choose to get shades installed to block the sun when the weather gets warmer in the summertime.  All-time of all, she can have an even meliorate view of the dazzler surrounding her home.

Of class, these considerations and their relevance will vary widely for unlike people and their personal situations.  But for anyone considering which is right for their home, the factors laid out above may help pb them to the respond.  In the stop, whether through a solar tube or skylight, letting more than light smoothen down from above can help transform a dwelling for the better.
