Can a Sun Tunnel be divided to go into 2 rooms?

Last weekend at the Kansas City Home Builders Association Home Show, I heard this question more than a couple times, so I’d like to address it here in the blog for anyone who is curious.

The short answer is…”no”…a Velux Sun Tunnel is not manufactured to allow for a “Y” tubing piece which will allow two separate tubes to divert light into two separate rooms.

Here are the main reasons this is not being done:

1)  There is no such “Y” tubing piece being made to fit the Velux  Sun Tunnels.  We do not recommend that folks try to make their own tube or use “dryer vent” tubing.  Sun Tunnel rigid and flexible tubing is not the same as tubing you can purchase in a home improvement store.  It’s made specifically for durability and energy efficiency.

2) Diverting light into two places would divide the light and both spaces would see less light than Sun Tunnels typically provide one space. 

3) Using a “Y” tubing section would require more “piecing together” of tubing in the attic, a practice we like to avoid.  More taping of tubing results in the increased risk that it will become detached or loose, thus compromising the Sun Tunnel.

Hope that answers your questions.  As always, give me a call if you would like talk skylights.

Skylight Tax Credits for 2011

Never thought skylights would qualify for tax credits?  They do, as long as they are Energy Star rated!

The details of the tax credits can be found on

but here are some basics taken directly from the website:

On December 17, 2010, President Obama signed the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010. This law extends the tax credits for energy efficiency into 2011, BUT at lower levels. The levels revert back to those in effect in 2006 and 2007, which were 10% of the cost of the improvement, up to $500, with a $200 max for windows, and several other set maximums.

Tax Credit Amount: 10% of the cost, up to $500, but windows are capped at $200.

Must be ENERGY STAR qualified.

You do not have to replace all the windows/doors/skylights in your home to qualify. And it doesn’t need to be a replacement either – installing a new window where there wasn’t one previously (like in an addition) qualifies.

Tax Credit does NOT include installation costs.

30% of cost with no upper limit

Existing homes & new construction qualify. Both principal residences and second homes qualify. Rentals do not qualify
