Vinyl and Fiber cement siding installation with Tyvek weatherbarrier in Maryland, Washington DC and Northern Virginia.

Tyvek House Wrap Installation

Maryland, Washington D.C., Northern Virginia

Hallmark Windows and Siding installs DuPont™ Tyvek® with a large portion of our siding jobs.

Tyvek is the original selective barrier technology.

Since the initial discovery in 1955 that led to Tyvek®, DuPont has been a recognized global leader in selective barrier technology. Amazingly Light Tyvek® has a higher strength-to-weight ratio than paper. So, lighter weights of Tyvek® can be used for most applications. Tyvek is Tough! It is strong and rip-resistant.

Incredibly Water and Moisture Resistant Tyvek® absorbs little or no moisture…and liquids simply run off its smooth surface. And, the physical properties of Tyvek® are the same, wet or dry!

With more than 30 years of residential performance on millions of homes, DuPont™ Tyvek® HomeWrap® is the world's leading housewrap.

DuPont™ Tyvek® HomeWrap® has the optimum balance of properties for superior performance against the elements and the competition. When using Tyvek® HomeWrap® you can be assured you are using the brand leader in weather resistant barriers.

A weather resistant barrier is a building's main protection against the damaging effects of the elements. A funtioning barrier must include two basic properties:

- It must have a high level of AIR RESISTANCE- to help prevent drafts, reduce energy bills and resist the flow of moisture laden air through wall cavities.

- It must have a high level of WATER RESISTANCE -to help protect the wall cavity from water

Tyvek is 100% Recyclable
