What does this even mean? 7700 is a useless number without a manufacturer. And LEEP glass? Maybe a Low-e typo? If so, what type of low-e? There's a wide range of performance when it comes to low-e. And double insulation properties? Maybe you mean a dual seal insulating unit? Explain further why this is advantageous over a single seal unit. I know why, but your customers should know why before you shite on a competitor. Double strength glass is by definition 1/8" thick (3.2mm). Any thicker and it's no longer double strength. Be honest with your potential customers. Don't rattle off industry jargon to make something sound fancier than it really is.

LEEP (Low Energy Emissitive Pyrolytic) Glass - Has a hard pyrolytic coating on the inside surface of the inner pane of glass. Makes for a .27 or lower U-Factor. It combines Northern and Southern Glass. The glass is rolled out of the machine in a molten state onto a bed of mercury. The molten glass is sprayed with the EP coating at this point. As the glass cools the EP coating turns into a hard shell fixed to the glass. The newly finished glass reflects shorter wave radiation with the LE and blocks the longer wave radiation with the EP. All this together makes the window more like a wall.

Double Insulation Properties - Vinyl frames are chambered with individualized pockets of airtight space to increase insulating values. They're doubled in comparison to the 5400 series, which is more comparable to the Window World window. Even then, the 5400 series is a step above WW's standard window.

This is all as fancy as it sounds. Hope this helps clarify what I meant!
