Delaware Energy Codes

Steel Building Insulation, a division of Building Outlet Corp., is a longtime industry leader in insulating metal buildings in Delaware and the surrounding region. We are able to keep insulation costs low by working directly with metal building insulation manufacturers, enabling us to offer extremely competitive prices on top-quality, name-brand insulation panels, thermal blocks and a broad range of related products and accessories, including, but not limited to, metal building insulation patch tape, steel banding, insulation knives, thermal break tape, washers, facings and building pins.

We provide steel building insulation for a wide range of commercial structures that are designed to keep Delaware buildings cool during the summer, warm during the winter, dry and condensation-free year-round. Thermal energy loss is one of the most substantial drains and expenses in a metal building owner's budget, and while adequate insulation can certainly be a money saver at any stage during the construction process, installing insulation at the time of building erection is the single most cost-effective method of installation. All Metal Building Insulation packages are cut specifically for the building size you request, and are available in a variety of insulation systems with varying R-values, depending on your structure's specific needs.

When purchased as a package, Steel Building Insulation orders include a variety of tools and accessories to simplify the installation process, including double-face tape rolls (to adhere the insulation blankets to the steel framing during installation of wall and roof panels), patch tape, fasteners, and steel banding used in higher R-value systems. Installing thermal blocks and high R-value insulation systems drastically lowers a building owner's overall "cost of ownership" over the lifespan of the building, in addition to offering numerous other owner benefits such as increased comfort and improved noise control. Whether you are looking to insulate a gym, greenhouse, aircraft hangar, storage facility, church or other metal or steel building, Steel Building Insulation can work with Delaware consumers to ensure that you are not only making the most of your investment, but making one that will ultimately pay for itself in only a matter of time.

Compliance with the energy code is determined at the local level and varies depending on the county or locality. The Delaware Energy Office will establish procedures for compliance certification. Local governments have the option of using alternative methods, such as the ASHRAE/IESNA 90.1-1999 Compliance Guide or COMcheck-EZ, to ensure that commercial buildings less than 5,000 sq. ft. meet the requirements of the code.
