Grill styles
Between the glass (BTG) grilles are encased between the two panes of insulating glass, leaving a smooth surface that’s easy to clean.
Simulated divided lites (SDL) grilles look like traditional divided light grilles, but offer the outstanding performance of our energy-efficient windows. SDL grilles are applied to the outer sides of the insulated glass for a more traditional profile – inside and out.
Window Grill Styles
Grill profiles

Glass Types
North Star Windows offer a variety of glass options that can enhance both the beauty and performance of your windows, including:

Bronze tint
Cuts down on the amount of glare and heat entering a building

LOF (Libby Owens Ford)
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 in summer. Energy Advantage Glass has a higher Solar Heat Gain Coefficient (SHGC) than Low-E glass designed for southern climates. It provides 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 other glass without a high SHGC.

LoE (Cardinal)
LoE 366 – Is recommended when cooling costs outweigh heating costs in your energy usage, or where summer discomfort from heat build-up should be an important concern. This is the best glass for most applications in a southern climate. It has a very high reflection rate of the radiant outside heat to prevent heat gain in summer and in winter it still retains radiant once you turn on your furnace! LoE 366 has a lower Solar Heat Gain Coefficient (SHGC) in order to minimize Solar Heat Gain that results in extra work for your air conditioning unit.

Argon gas filled
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.

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.

RE 29 double glazed

RE 39 triple glazed


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