With Walls Of Windows, The Glass Matters!
All dual sliding windows come with our EZ Glide Quad Roller system!
Available exclusively by C-Thru, it carries double the number of rollers as our competitors, minimizing sash racking and making for extra smooth operating windows. Our vinyl windows come with a substantial 3 ¼” thick framing, dual cam locks and a variety of glass options to choose from. They come in three different configurations…
- Sliding windows are available in 36”, 42”, 48”, 54” wide with custom widths available.
- Fixed windows are available in 24″, 36”, 42”, 48”, 54” wide with custom widths available.
- All standard windows are either 54″ or 60″ high
- All sliding windows come with a fixed exterior screen
SmartGlass 30 | 60 | 180
Most sunrooms feature a lot of glass, so it’s important that the glass itself is clear and strong. Duralite has up to twice the clarity of regular glass and is strong enough to withstand impacts without breaking or scratching.
Choose from three different types of Duralite glass:
Single Pane Clear Glass (Smart 30)
1” Sealed Double Low E Pane Glass (Smart 60)
1” Sealed Triple Low E Pane Glass (Smart 180)
*The triple pane glass option is expensive and should only be considered if you are in extreme weather areas and the rest of your home has triple pane windows as well!

How to read the table...
U-Value Radiant (non-solar) heat transfer through the glass measured in BTU’s/sq.ft./hours x deltaT. The lower the number, the better.
Shading Coefficient: An index of solar heat gain rejection. The lower the number, the better.
Solar Heat Gain Coefficient: Similar to shading coefficient. The lower the number, the better in terms of solar heat gain rejection.
Visible Light %: The amount of visible light allowed to transfer through the pane of glass.
UV% The % transmission of ultraviolet radiation through the glass (see below!)
On the left, you will see the results of our in-house UV transmission test conducted in the factory using a UV transmission meter and a UV light pen. This is given to further illustrate the efficiency differences between the glass packages that we offer.
Standard upgrade on all sunrooms and modular wall systems, with both single and dual-pane windows
8 times stronger than residential glass – nearly unbreakable
Stronger than laminated and safety glass, decreasing the chance of breaking – rated as good or better than tempered glass!
Patented warm-edge spacer technology for maximum insulation
Safe and shatter-resistant.
The window is only as good as its seal!
This one element of your room, the spacer between panes of glass, although unseen, is one of the most important elements in the construction of your windows and doors. Duralite spacers are the most advanced, energy-efficient spacers in the industry. Commonly known as ‘warm edge technology,’ it acts as an insulator between the outside temperature and the inside of your room. Duralite spacers are made from non-metallic structural elements that insulate extremely well and do not degrade over time.
SUPERIOR THERMAL PERFORMANCE
The thermal performance of a window plays a major role in household energy conservation. A high-performance window system will keep your energy costs low by reducing heat loss in the winter and heat gain in the summer. Duralite, combined with Low-E glass and air, produces one of the highest-performing, energy-efficient window systems, saving you money on heating and cooling costs. Duralite is an ENERGY STAR® qualified product.
DURALITE® SPACER DESIGN
Duralite is a flexible, warm-edge spacer featuring a unique no-metal, composite laminating technology that provides superior durability and thermal performance in insulating glass units. To achieve the ultimate in performance, all in a single-seal design, Duralite is preassembled with an air-filled polycarbonate shim, butyl sealant, a three-sided continuous moisture barrier, and a desiccated topcoat. The results are better performance now and in the future.
REDUCE CONDENSATION FOR A CLEAR VIEW
When you see condensation inside a dual-pane window, that means the seal has failed. Our exclusive high-performance dual and triple-pane glass is made using the latest technology in insulated glass seals. Poorly insulated windows allow moisture to condense. Condensation can obstruct your outside view, reduce natural lighting, and damage interior finishes. Moisture and condensation can also increase the risk of mold. Windows built with Duralite warm-edge spacers reduce condensation, keeping moisture off your glass for a clearer view to the outside.
