My wife wanted more natural light in our kitchen. I helped build our house so I knew what would be involved. I looked into tubular skylights and found plastic and card board with reflective tape. We live in the Midwaest and our winters are severe some times. I looked for a company from my area or a similar climate. I found Sun Bubble out of Canada. All metal construction and a great warranty. I installed the skylight by myself in 5 hrs. That included telling 3 sidewalk rubber necks what I was doing. We love the light. Call the Illinois office 630-536-2729 They will send brochure and price sheet.
