Frequently Asked Questions

Can I have both skylights and sun tunnels in my home?
Absolutely! Many homeowners use skylights in rooms where they're practical (kitchens, bathrooms, living rooms) and sun tunnels in interior spaces where skylights aren't feasible (hallways, interior bedrooms). This combination maximizes natural light throughout your home.
How much light does a sun tunnel actually provide?
A typical sun tunnel provides the equivalent of 3-4 100-watt light bulbs worth of illumination on a clear day. Light output depends on tube diameter, length, and weather conditions. Shorter tubes deliver more light than longer ones.
Will a sun tunnel work on a cloudy day?
Yes, sun tunnels work on cloudy days but provide less light. On overcast days, you might get the equivalent of 1-2 light bulbs worth of illumination. This is still enough to reduce daytime artificial lighting needs.
Can I install a skylight in a room under a second story?
No - a skylight requires a direct roof opening above the room. If your room is under a second story, a sun tunnel is the perfect solution. The tube can route light from the roof down through walls and floors to reach the interior room.
Which option is better for energy savings?
Both reduce energy costs by providing natural lighting during the day. Skylights typically save more because they provide more light output. However, sun tunnels offer better value for the cost - you get significant energy savings at a lower installation price.
Do sun tunnels require maintenance?
Sun tunnels require minimal maintenance. The exterior dome should be cleaned 1-2 times per year to remove debris and maximize light transmission. The interior tube is sealed and requires no maintenance.
Can I add a shade or blind to a sun tunnel?
Some sun tunnels offer optional diffuser shades that can reduce light output or provide privacy. However, they don't offer the same level of light control as skylight shades. If light control is important, a skylight with motorized shades may be better.
How long do skylights and sun tunnels last?
VELUX skylights typically last 20-30+ years with proper installation and maintenance. Sun tunnels also last 20+ years. Both are durable, long-term investments in your home's natural lighting.
Which option adds more home value?
Skylights typically add more perceived value because they create a dramatic visual impact and are more visible to potential buyers. However, both skylights and sun tunnels improve home appeal by providing natural light and reducing the need for artificial lighting.
Can I retrofit an existing skylight to a sun tunnel?
Not directly - they're different systems. However, if you have an existing skylight that's leaking or outdated, we can replace it with a new VELUX skylight. Or, we can install a sun tunnel in a different location to provide light to another room.
