Insulated Vinyl Siding

Wednesday, November 21st, 2018 by Ruthy Singletary

Vinyl siding was first introduced to the exterior cladding market in the early 1960s. The product grew in popularity over the next four decades because of its durability, versatility, value and ease of maintenance.

Then, in 1997, insulated vinyl siding was made available commercially-- and many argue that in addition to a stylish choice for your house-- it's a great return on investment; and one that will keep you toasty with the cold winter approaching!

Check out some basic facts about the insulation and energy-saving benefits of insulated vinyl siding below:

How does siding work?

Vinyl siding is manufactured primarily with polyvinyl chloride (PVC), a material that gives it impact resistance, rigidity and strength. Since 1995, vinyl siding has been the number one choice of exterior cladding across the United States and Canada. U.S. Census Bureau statistics show that for the past 20 years, more homeowners have sided their homes with vinyl than any other cladding.

While wood siding is fastened tightly to the house, vinyl siding literally hangs from nails driven through horizontal slots at the top of a panel's nailing hem. The reason for the loose nailing has to do with the vinyl's (and polypropylene's) need to expand or contract as the temperature changes: A 12-foot length of plastic siding can expand as much as 5/8 inch with seasonal temperature swings. If nailed tight to a wall, it can buckle on hot days.


"The worst thing you can do is nail vinyl tight," says Tom Silva, a construction specialist. To ensure that the panel is free to move, the nailheads shouldn't contact the hem, but should be left about 1/32 inch proud. Conversely, if nailed too loosely the panels will rattle noisily whenever the wind blows.

How is insulated siding different than traditional vinyl siding?

Compared to traditional vinyl siding, its insulated vinyl counterpart increases the R-value of your home which means reduced energy bills throughout the year. Insulated vinyl siding also offers better weather performance and better sound control properties than traditional siding.
