SmartGlass 30 | 60 | 180    (details & options)

Most sunrooms are made with 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)



SmartGlass Efficiency U-Value Shading Coefficient Solar Heat Gain Coefficient Visible Light % UV %



How to read the table...



 U-Value Radiant (non-solar) heat transfer thru 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.

The % transmission of ultraviolet radiation through the glass.

DuraLite Windows

  • Standard upgrade on all sunrooms and modular wall systems, with both single and dual pane windows

  • 8 times stronger that residential glass increasing security - 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 and minimum argon loss

  • 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 with non-metallic structural elements that insulate incredibly well and do not break down over time.


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 your heating and cooling costs. Duralite is an ENERGY STAR® qualified product.




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.


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 collect in the form of condensation. 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.
