If you are a homeowner that is concerned with energy efficiency and environmental friendliness, you likely try to make any decisions about home improvements with these factors in mind. As such, if you are looking to update and upgrade your home’s exteriors, you may wonder what you can and should do to make everything more energy efficient and eco-friendly. Before you get started on any projects, get to know some of the options that can help you to attain these goals. Then, you can be sure that you are making the right choices for you and your home. Siding Replacement Your home’s siding is one of the most important aspects of its exterior. The siding protects your home from harsh weather and the elements and helps to insulate and protect the inside of your home. It also covers the largest area of your home. Because of this, replacing your siding is a great opportunity to make your exteriors more eco-friendly and energy efficient. When you are looking for greener options, you will want to look for replacement siding that is at least partially made from recycled or repurposed materials. Generally, this leaves you with the classic and traditional option of wood siding or the more modern options of metal siding. Metal siding is usually made of aluminum which can be formed, at least partially, from recycled metals. Wood siding, on the other hand, can use reclaimed or repurposed wood from previous construction as the base siding material. If reclaimed wood siding is unavailable, new wood siding can also be eco-friendly if it is harvested from sources that are certified by the Forest Stewardship Council (a group that oversees the lumber industry and determines if the product is being harvested sustainably). Both metal and wood siding are also considered to be energy efficient. Roof Replacement Another important aspect of your home’s exteriors is, of course, your roof. The roof is one of the primary sources of thermal energy transfer in your home and is the area most exposed to direct sunlight. Because of this, it is important that you have a high-quality roof that prevents thermal energy transfer. There are many roofing materials available on the market. However, one of the most energy efficient and the most environmentally-friendly options would have to be recycled rubber roofing. This roofing material is made of recycled tires and is a thick and dense roofing material. Rubber absorbs heat and cold without transferring it through, which makes it a very good insulator for your roof as well. Other eco-friendly and energy efficient roofing options include recycled wood shingles, recycled asphalt shingles, metal roofing, or even a living roof (a roof made of a thin...
