Getting a skylight has many benefits from reduction in energy consumption to privacy improvement but with many different types of skylights each one having their own benefits and weaknesses. To help make up your mind on getting a skylight and what type of skylight, we going to have in-depth look at ventilated and opening skylights to see which is the best option for you.

Benefits of ventilated and opening skylights.

Temperature Control

Ventilated and opening skylights main selling point is their ventilation capabilities where ventilated skylight are a fixed position and provide passive ventilation while opening skylights are mechanical skylights that can be opened and closed as needed either manually or automatically depending on the type you choose. This additional ventilation is the main benefit for these types of skylights as the ventilation provides better temperature control over non-ventilated skylights by allowing better airflow releasing hot air trapped inside the home or office while drawing in cooler air. This improved temperature control also help improve the energy efficiency of the skylight by reducing the reliance on air conditioning.


The improved airflow of these skylights helps in improving the life span of the roof by providing two benefits, the first being reduction of moisture by releasing hot humid air that builds up inside and proving airflow which help keep things dry. Allowing moisture to buildup can cause mold, rot and mildew to start growing over surfaces especially wooden surfaces that well be eaten away by the moisture and can cause structural damage to the building and mold or rot of wooden surfaces can introduce unpleasant smells.

The other benefit to your roof’s life span provided by ventilated skylights is reduced weather damage especially in cold climates where snow and ice is common since the ventilation of warm air released from the inside will helping melt the snow preventing ice dams from building up, and when in hot climates the extra ventilation releasing built up hot air can help cool roofing materials reducing the chances of heat damage such as cracking of tiles or warping of shingles.

These two factures help extend your roof’s life span, saving you from expensive repairs or replacement of your roof.

Negatives of ventilated and opening skylights.

Now all these sounds great and if you are looking to maximize these benefits then the ventilation type skylights maybe the best options for you but while they have improvements in these areas, they have their own weaknesses.

Opening skylights: Mechanical failure

Starting with opening skylights the main con for these types of skylights is the risk of failure in the mechanical system as with any device with moving parts there is the risk of failure due to wear and tear, blockages and weathering (eg. rust). With this there is a need for more frequent maintenance and cleaning to monitor for any damage or to clear away any potential blockages.

Passive ventilated skylights: Heat loss

For passive ventilation skylights the main con is lack of control in temperature and air flow while this it generally not an issue especially in hot climates, in cold climates it can act like a gap in the home or office’s insulation meaning the warm air inside is constantly leaking out increasing reliance on heaters and air conditioning. So, these options may be best if you live in a predominately warm climate area and have easy access to your roof/skylight for cleaning and maintenance.

It is important to look at both the positives and negatives of each type of skylight when decided on what you would like to have installed in your home or office. So, when looking at ventilation type skylights some question to think about would include, what type of climate and weather conditions are most frequent in my area? And will the skylight be accessible to me for cleaning and maintenance?

Frequently Asked Questions

What are the cons of tubular rooflights?

There are many potential drawbacks to tubular skylights. The most common issue is that they require professional installation in order for them to be properly sealed and secured. This process can be time-consuming and costly, which could result in higher installation costs than the initial fixture purchase price. Because of their design, tubular rooflights are smaller and may not be able to fit larger roof openings. These skylights can also block some ceiling space, which is not the case with traditional skylights. Natural light can still enter from all angles thanks to their design.

One potential problem is that tubular skylights may need direct sunlight to function properly. This could limit their utility in certain climates. You should also be careful when choosing additional fans or air ventilation systems. These fixtures can introduce heat into your home and make it uncomfortable in the summer months. Finally, tubular skylights cannot offer an expansive view of the sky or landscape like traditional fixed glass models do.

Which is better: sun tunnels or skylights?

When bringing natural light into a home, skylights and sun tunnels can be great options. You will need to know the differences between them so you can make the right choice for your space.

Skylights make a great addition to basements and bathrooms, as they provide extra sunlight or dramatic window effects. Skylights are more spacious than sun tunnels, and offer a wider view through the glass dome. These skylights can be used in rooms that have less furniture or need privacy. Plus, they are easier to clean as you can reach all surfaces from within.

Sun tunnels are narrower than skylights. They can be used to create a space with limited windowsill area, such as hallways or closets. Sun tunnels work by reflecting the sunlight from an interior mirror into the room. They allow natural sunlight to penetrate the room without direct exposure from outside.

When it comes to adding natural sunlight where you most need it, there is no one-size fits all solution. Consider your desired outcome regarding views and privacy along with available space when deciding which is best for your needs: skylights or sun tunnels.

Is it possible to use solar tubes in winter?

It all depends on the product and how it is installed. Solar tubes, also known as sun tunnels or light pipes, are installed within a home’s roof, which can trap heat and result in warmer indoor temperatures. But, products made for colder climates may not perform as well during winter months where there is less sunlight.

To maximize the effectiveness of your solar tubes during winter, you can use reflective mirrors or insulated tubing. This will help to capture more light and increase insulation. Many manufacturers offer snow guards, which attach to the roof of the house and prevent snow from falling on the solar tube. Install the solar tube facing south to get maximum sunlight exposure during all seasons.

The interior dome or lens can be cleaned with warm water, a sponge, or a non-abrasive cloth to improve the lighting efficiency. As dirt builds accumulation on both sides of the dome this may impede light entering into your house resulting in less brightness indoors. You must maintain your solar tubes by giving them regular care and maintenance during all four seasons.

Even though some models might not perform as well during winter months, it is possible to still use them efficiently by following best practices like proper insulation, direct sunlight orientation, and regular cleaning. Properly installed solar tubes will allow natural light to enter your home during summer and winter.

Can solar tubes ever be closed?

Yes, it is possible to close solar tubes. You can open and close sun tubes depending on their design. Caps are a permanent way to control the light entering a tube. Caps are placed at the top of tubes to keep outside light out and prevent precipitation from building up. A few solar tubes also have an acoustic layer that helps reduce noise in the room or an integrated blind. This gives you more control over the amount of natural light entering your space, without the need to manually open/close a shutter or operate a cap. Solar tubes can also be opened and shut down to allow for better daylighting control.

Do sun tunnels get dirty?

Sun tunnels are a great way to bring natural sunlight into dimly lit areas. They don’t get stained like normal windows. Sun tunnels often have high-quality polycarbonate and acrylic domes which reduce dust and dirt entry. Their thick lining material deflects smaller objects brought in by wind and other environmental factors. This helps to keep your sun tunning bright and clean.

Sun tunnels are also easy to maintain since all you need to do is lightly rinse them with a mild detergent or soap every few months. Sun tunnels last for years provided that they are not in direct proximity to chimneys or smoke sources. A sun tunnel is a great way to brighten up any area, and it requires very little maintenance.

Many sun tunnel systems have self-cleaning features, such as wipers that clean the lenses of dirt and dust. This eliminates the need to spend time cleaning them. This makes sun tunnels even more suitable for people who want to maximize sunlight but can’t dedicate time specifically to cleaning them regularly.

Can sun tunnels be used at night?

Are sun tunnels effective at night? Yes! Yes, even in low light conditions and without direct sunlight, sun tunnels are able to bring natural light into any space. Sun tunnels gather sunlight from the roof, and then direct it through a tube (or series of tubes) to the place it is needed.

Sun tunnel systems harness daylight by a dome that covers the roof. The dome directs sunlight down the tunnel and stores it in energy-efficient luminaires. The reflective material inside each tube helps keep the light quality consistent throughout its journey.

The night is when solar energy from the day is released by strategically placed LED lights located at specific points in their design system. This allows for illumination of a space without consuming any power from the grid. So while they may not get as much light as in the daytime, they still provide an effective lighting solution that requires no additional power source whatsoever. They’re ideal for homeowners and businesses who are looking for an off grid solution that doesn’t require power supply or maintenance. This can help consumers save money and promote sustainability over time.

How To

Brighten Up Your Space: How to Add a Skylight to Any Room

A skylight is a great way for your space to be more spacious. You must first measure the area you need to install the skylight. This should take into consideration both the available space as well as the desired level and intensity of sunlight. You should then prepare safety precautions, such as weather sealing and insulation.

After deciding the type of skylight that is most suitable for the area, based on its size and technical requirements (operable/fixed), you will need appropriate mounting supports like rafters and beams.

The last stage of the installation consists of proper fitting for all components including careful glazing with sealants for energy efficiency standards and aesthetics.

Yes! Skylight windows bring natural daylight into your home more efficiently than traditional electric lighting sources. They are able to catch maximum sunlight from multiple angles and reduce dependence on artificial lighting sources. Skylight windows also fill rooms with light, which can affect moods subtly more than other types of interior design. They also reduce electricity bills by using less artificial lighting sources at certain times of the day. This can result in lower maintenance costs. A realistic sun exposure creates better indoor air quality. Fresh air flows freely in enclosed spaces, which allows for less pollution. This reduces the possibility of allergies.
