What's the Difference in Today's Vinyl Siding?

During vinyl siding installation, homes are pre-wrapped in a vapor barrier. A vapor barrier is a water-resistant, paper-like material with a waxy look and feel. The wrap covers all sides of a home, forming a layer of protection underneath the siding. It can integrate well with other materials, even stucco.

Today's vinyl siding installation offers a water barrier system that includes:

  • Exterior cladding
  • Flashed wall openings and penetrations
  • Water-resistive barrier material
  • Sheathing

These elements create a moisture-proof barrier that works just as well as any other type of siding material to keep your home dry and comfortable.

Vinyl Siding Installation and Regulations

Vinyl siding has greatly evolved since it became popular in the U.S. market in the 1960s. Though vinyl siding itself is a nearly impenetrable barrier against moisture, a vapor barrier can take the protection much further. Just like vinyl siding, vapor barriers are meant to last. Assuming proper care and maintenance, modern materials work well enough to protect your home for many decades.

Most states require that the vapor barrier be utilized during the vinyl siding installation. Since the rules and regulations vary from state to state, it is important to learn what your state's regulations are before installation begins.
