What sun tunnel should i use on my roof?
For all pitched roof/sloping roof sun tunnels, you can purchase them in their flexible or rigid. Each variation has its own benefits and depending on your home. You may have to go with the flexible.
Flexible sun tunnels come with a flexible reflective tube to pivot around obstructions or unmoveable items in your attic. The flexible sun tunnel usually comes in cheaper than the rigid sun tunnel. However, due to its difference in material and pivotable tube, they usually produce less light within your home as the rigid sun tunnel maximises daylight with more light bouncing off the surface of the ridged tube.
Rigid sun tunnels come with a solid tube which goes straight down from the attic roof to the attic floor (room ceiling). The rigid cannot pivot around unobstructive items or move to the conditions of your home. Rigid sun tunnels can be bought with extension pieces to increase the reach of your new natural daylight.
