So glad we came across this company during our searches for a pergola. Many quotes came in higher & didn't offer the terrific warranty they do here. Initially we were quoted about 6-8 weeks but they were able to get us in much sooner. We first just hired them for an open pergola on the side of our home. After looking into updating our covered patio area also we went ahead & contacted Marco who was able to accommodate our time frame & budget. They were able to get both area done within a few days. The installers were very efficient & tidy. Definitely would not hesitate contacting them again for another other work. Professionalism all the way!

Glass Opt.

Other than the framing and solid insulated areas, a sunroom is made almost of all glass. With this in mind, glass is one of the most important features to choose correctly when designing your new sunroom. C-Thru offers five unique glass options in its proprietary SmartGlass ™ line. Starting with the SmartGlass 30, it's our most economical option. This is a single pane glass with the least amount of insulation. Our more energy efficient glass option is our SmartGlass 60. This dual pane high performance Lo-E glass is considered to be the "Best Value" when taking insulating abilities and cost into account. However you chose is yours, scroll down the page to learn more about what Smart Glass package will work best for you.

Single pane Glass options
· Smart Glass 30
· Smart Glass 40

Dual pane Glass options
· Smart Glass 30+
· Smart Glass 60
· Smart Glass 90

*Not all glass options are available for every product. Contact your local authorized, independently owned and operated C-Thru dealer for more info.


Safety is also a paramount concern when surrounded by so much glass. C-Thru's exclusive DuraLite™ Glass is 8 times stronger than standard residential glass and is strong enough to withstand impacts without breaking or scratching. DuraLite glass is stronger than laminated and safety glass to protect against accidental breakage. Duralite is standard on all rooms on both single and dual pane windows.


C-Thru Sunrooms are engineered to be energy-efficient to help control your heating and cooling bills. Along with using SmartGlass™, C-Thru uses Tuff-Core™ wall panels and WeatherGuard™ roof panels. These panels are made of a highly-energy-efficient materials. 3" of Tuff-Core™ has as much insulation as 8" of fiberglass to help regulate the temperature inside of your sunroom.
