As such, the units meet a range of industry standards for structural integrity and thermal concerns, in addition to being eligible for tax credits. The 5500 series features Intercept spacers for low U-factors and advanced low-E glass available with the Simonton Solar System glass package. The Solar System package upgrade comes with krypton gas and a 1-inch space between the panes. Reflections 5500 units are available with brass hardware and woodgrain color options. 800.746.6686. www.simonton.com.
