The Science Behind Low-e Glass

Choosing the right Low-E stack for Mandeville

Low-E, or low emissivity, is a microscopically thin coating on the glass that manages heat transfer without turning your window into sunglasses.

Fiberglass is dimensionally stable in heat and accepts paint, typically costing more than vinyl but less than top-end wood-clad.

Thermally broken aluminum is strong for oversized glass but needs a smart Low-E to control heat gain.

• Keep weep holes clear with seasonal rinsing so pressure differentials do not pull water into the frame during storms.
• Photograph labels and serials after install for warranty and insurance files, especially on impact units.
