Other alternatives are made of a polyurethane foam insulation core - offering six times the energy efficiency of wood - faced on both sides with vinyl or aluminum. These typically cost for a 6-foot-wide door. All well-made nonwood doors are designed with thermal breaks (separations between indoor and outdoor surfaces that block the conduction of heat or hardwoodfrontdoors cold.) Glazing options Of course, the largest part of a glass sliding door is glass. To make a door truly energy efficient, high-performance glazing is key. Fortunately, this is standard with most high-quality sliders. You''ll find double-paned glass with low-E (low energy) coating and, in some cases, argon gas filling. Low-E reduces heat transfer and protects against ultraviolet damage; argon gas filling provides greater insulation. Some manufacturers let you specify the glazing you want when you order. Where sun-caused fading or damage can e a serious problem, you may want to opt for glass with a solar bronze or solar gray tint to reject ultraviolet rays. In addition, some companies offer hardwoodfrontdoors decorative stained or beveled glass with true brass caming (leading). For bathrooms or other places where privacy is a concern, obscure glass is available.
