IECC Metal Building Insulation Codes in Massachusetts

Massachusetts Energy Codes

When Massachusetts residents, contractors and business owners grow tired of pouring their hard-earned savings into escalating energy bills, they contact Steel Building Insulation, a division of Building Outlet Corp. We are a leading provider of steel building insulation, foam insulated panels and insulation accessories to Massachusetts and the rest of New England.

Installing new insulation, or performing an insulation retrofit will result in tremendous energy savings for metal building owners, particularly in climate-controlled environments where the interior must be kept cool in the summer and warm in the winter. Installing an effective fiberglass insulation system in your new or existing metal building involves a minimal initial expense – a large portion of which may be tax-deductible – that will pay for itself in just a matter of time, in addition to offering a variety of other benefits, including noise-control, increased user-comfort, improved indoor air quality and minimized strain on our natural resources. Additionally, when equipped with a laminated vinyl/polypropylene vapor retardant known as facing, quality fiberglass insulation reduces condensation and mold build up, resulting in better overall climate control and a safer interior environment. Facing materials also offer bright, reflective wall and ceiling treatments, which increase both lighting efficiency and safety.

We also offer a broad selection of insulation panels, insulation rolls, facings, tabs and accessories to fit your particular project, regardless of scope, size or other criteria. We carry both single and double-layer insulation and blankets with varying thicknesses and R-values, and our knowledgeable sales team is available to assist you, if need be, in determining the best particular product or products to fit your building’s specific needs.
