Siding With Insulation Built In

Description

• On the outside, insulated siding looks just like regular vinyl siding. The siding is typically molded to look like overlapping horizontal rows. The insulating layer is found on the back of the siding. The insulation is laminated and molded to match the shape of the siding. It is permanently adhered to the siding itself so the two become one permanent piece. The attachment reduces the risk of separation and breakdown of the insulated siding. While the two pieces are adhered snugly, the insulated siding is still flexible so that regular contracting and expanding doesn't damage the siding.

Rating

• Like regular insulation, siding with insulation built in is tested and rated to show how well it prevents air movement through it. The insulation component of the siding is assigned an R-value, the standard measurement for insulation effectiveness. The siding component is also tested against industry standards to determine its effectiveness and durability. The ratings and standards help you compare different brands and versions of insulated siding products.

Advantages

• When you choose siding with insulation built in, you add an extra layer of energy efficiency to your home. The insulated siding works with the existing siding in your home's walls to reduce the amount of heat transferred between the home's interior and the air outside. This often translates to a savings on your utility bills since your system won't have to work as hard to heat and cool the home. Integrating the insulation with the siding means you are able to take care of both components with one installation process instead of first installing separate insulation and attaching regular siding on top.

Disadvantages

• Insulated siding costs more to purchase and have installed than regular vinyl siding. According to "Architect" magazine, the insulated siding often costs an additional 25 to 30 percent over regular vinyl siding. You also face a limited selection in materials and styles when it comes to insulated siding. The effectiveness of the siding depends on your local climate. If you don't have extreme temperatures in your area, the additional insulation won't make a large impact on your energy savings.
