Marvin offers many glass options for energy efficiency, code compliance, sound reduction, and aesthetics.  Depending on the product and option they may be Single Glazed (SG), Insulated Glass (IG), or Tripane (TG).  The standard glass option is IG with Low E2 and argon fill between panes.  Here are some standard and decorative glass options.

Our standard glass option is dual pane, insulated, Low E2 with Argon gas. It is a simple means of maximizing your home’s thermal efficiency year-round. Low E2 reflects heat back to its source, so summer heat is reflected outdoor and indoor heating in the winter is retained. Low E2 also blocks up to 84% of UV rays to reduce fading and damage to upholstery and carpet.

Low E3 (low solar heat gain, good for southern climates), Low E1 (high solar heat gain, good in northern climates), Low ERS (Room Side), Low ELR (Light Reflectance), obscure options, Tempered, and Tripane.

All options are available either air or Argon (standard) filled. For more energy efficiency, a krypton-argon blend is also available.

Marvin also can provide decorative or specialty glass options.  That includes Ornilux® sometimes known as bird glass and Low ELR sometimes known as turtle glass where a low reflectance coating is added to Low E glass.  In many coastal regions, sea turtles nest and lay eggs on the beach. These animals have poor eyesight. They can easily mistake excessive lights on shore for the moon. Instead of following the moon back to the ocean, they follow light on shore putting them in great danger. Many species of sea turtles are now listed on the federal endangered species lists. To help protect the turtles, codes have been written to limit light on coastal beaches.  Ornilux® glass takes its cue from the web of the Orb Weaver spider, which catches ultraviolet light nearly invisible to the human eye, but is easily detected by birds. In nature, this design serves to protect the spider’s ability to capture prey.  In building construction, the same engineering reduces the risk to birds in flight.  Collision with glass remains the highest non-natural threat to fowl because, in many instances, the glass itself is unseen by birds, while the reflection of nearby trees in the glass gives a deadly illusion which threatens their safety.
