Vinyl vs CBS. Our home up north is frame. We bought a CBS pre-owned villa. CBS is a bit more money. We rented a frame for 3 months and think the CBS is much quieter and most important we like the look of CBS. Solar tubes are great. We have one in each bath. If there is a moon you do not have to turn on the light in the middle of the night. Most often you see them in baths but we saw one that was installed over the counter in an open kitchen plan and it was really nice.
