Glass Options

The type of glass used will have a direct effect on the energy efficiency of your windows and doors.

A more energy efficient glass product will improve your home’s energy performance in every season, so you’ll save energy – and money – year-round.

The glass in all North Star windows meets or exceeds industry standards. Glass is also available in a variety of attractive and practical options.

Argon Gas Filled

argon_glazing

Thermal performance is improved by replacing the air between the panes of a window with Argon gas, an inert, slow-moving gas. Argon gas helps prevent heat loss to improve energy efficiency.

Bronze-Tint Glass

Glass that features a bronze tint can cut down on the amount of glare and heat entering a building.

 

Krypton Gas Filled

Krypton gas is an inert, slow-moving gas that improves thermal performance. Denser than Argon, Krypton gas does an excellent job of preventing heat loss. Available exclusively in North Star triple-glazed windows.

LoE 366 (Cardinal)

LoE 366 is recommended when cooling costs outweigh heating costs, or where summer discomfort from heat build-up is a concern. It has a lower Solar Heat Gain Coefficient (SHGC) and a very high reflection rate in order to minimize radiant outside heat, preventing heat gain in the summer while still retaining radiant heat in the winter. LoE 366 is the best glass for areas of direct sunlight and most applications in a southern climate.

LOF (Libby Owens Ford) / Pilkington Energy Advantage

LOF – Pilkington Energy Advantage Low-E is the best glass for most applications in a northern climate. It has a very high retention rate of the heat in your home in winter and prevents heat gain from outside in summer. Energy Advantage Glass has a higher Solar Heat Gain Coefficient (SHGC) than Low-E glass designed for more southern climates, providing free winter heat for your home. Since as much as 95% of your energy expense for heating and cooling combined is for heating, this glass is more cost effective than glass without a high SHGC.

Obscure Glass

Obscure glass provides an effective shield without shutting out the sun. Obscure glass is particularly useful for bathrooms, basements or along walkways. North Star offers obscure glass in pebbled or glue chip pattern.

Self-Cleaning Glass

A unique treatment that allows the glass to break down organic dirt that collects on the surface. Dirt washes away with the next rain, leaving no streaks or spots. Pilkington Activ™ Self-Cleaning Glass is available in every North Star window.

Tempered Glass

Tempered glass offers added strength that is up to four times greater than conventional glass so that when shattered, it breaks into small pieces. It is required as safety glazing in patio doors, entrance doors, and side lights.

Triple Glazing

Triple-glazed windows utilize three panes of glass to dramatically reduce condensation and thermal transfer while insulating as much as 60% better than double-glazed windows. North Star’s optional triple-glazed windows offer incredible energy efficiency.
