Alpha 3 1/2″ Wall
(Cross Section)

The Alpha 3 1/2″ aluminum wall system is our original wall system first released in the 1960’s. Since then, we have made many refinements to the product, yet the concept of an affordable way to add space hasn’t changed. It is ideal for 3 season usage and its tuff and durable design will last you years with just a little maintenance. It is very conventional while adding value to your home.

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

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.
