New England’s weather takes a toll on your home’s exterior. An extra weatherproof barrier can bring many benefits to your home, especially during New England winters and muggy, rainy spring and summers.

At Coastal Windows & Exteriors, we always strip a home when we install vinyl siding as we need to check for any rot and leaks. Our New England homes need all the help they can get with defending against the harsh weather elements.

This is when products like house wrap and siding foam board enter the picture which provides excellent protection against moisture, prevents water penetration and actually channels water away from your home, while providing a breathable barrier technology for many years.

Think of it as the evolution in water drainage, beathabilty & durability…It’s the exterior upgrade that you never knew you needed!

House Wrap Prevents Moisture Damage

The primary purpose of house wrap is to prevent wind-driven rain and moisture from penetrating from reaching the sheathing and internal damage to your home. It assists with maintaining a dry building structure.

optimal moisture vapor transmission

This is important because moisture can be incredibly dangerous and damaging to your home.

For example, moisture can deteriorate wood siding. When the wood is exposed to moisture without treatment, it can even lead to rotting wood.

With house wrap applied to your siding, you will have a weatherproof and waterproof barrier for incredible protection. In fact, house wrap is essentially the #1 defense mechanism. House wrap ensures that you have protection no matter the circumstances.

House Wrap Prevents Mold

Mold is perhaps the most concerning aspect of moisture damage. Not only is it unsightly, but it is also damaging to your exterior. In the worst-case scenarios, it can lead to health issues.

House wrap prevents mold by ensuring that moisture can’t reach the exterior. Moisture is one of the key elements that mold needs to grow and flourish.

The vapor-permeable membrane allows moisture in the home to escape, protecting your home from rot and mold.

House Wrap Reduces Drafts

When you’re dealing with a drafty home, it can cause your home to feel cold and uncomfortable. The protective layer of house wrap keeps drafts out and can serve as a barrier against lost energy. This air barrier helps reduce your heating & cooling costs!


Is House Wrap Necessary?

The best approach is to have your house wrap installed before your new vinyl clap siding or vinyl cedar shakes. This way you can be sure that your home is receiving proper protection. As Kimberly-Clark says, Don’t just wrap your home, BLOCK it against the elements!

As you can see, house wrap is necessary to prevent damage such as the following:

Prevention from mold that results from contact with moisture. Moldy siding will break down the structure of your siding and leave the exterior exposed.

    1. It keeps your exterior otherwise protected if the vinyl becomes damaged. If wood is exposed to the elements, it’s subject to chipping, peeling, and rot.
    2. House wrap also reduces drafts and helps your family feel comfortable no matter the time of year.
    3. Bottom Line:  It prevents the penetration of water and channels water away from your home, while providing a breathable barrier that protects your home for years to come!

That’s a wrap on what you need to know about house wrap! Next, let’s explore the benefits of siding foam board.

The RIGHT Way to Install New Siding…with Foam Back Insulation?

In the most energy-efficient options of the vinyl exterior, foam siding is installed under the panels for moisture control and many other advantages. Foam siding is engineered to reduce heat transfer, resulting in energy savings and a durable layer against unexpected impact to your siding.

With a 1-inch layer of foam siding under your vinyl, you can receive an immediate increase in R-value of 5. Meanwhile, air infiltration is blocked within the wall cavity for additional comfort.

HINT:  The more insulation that fits behind your siding the higher the R-Value.

It’s the most cost-effective time to add insulation to your home’s exterior…when you reside in your home with vinyl siding…do it right the first time and enjoy the benefits for years to come.

Vinyl siding with foam back insulation ensures you will get the most from your new siding:  premium appearance, improved durability & energy savings.

Can Siding Foam Board Save Energy?

There may be an energy leak in your walls that is costing you money every day! Did you know that 35% of your home’s energy is lost through the wall studs?

This primarily happens when the walls are uninsulated, making it easy for energy loss via heat transfer. If 35% of your home’s walsall is made up of uninsulated studs, that is like having one entire wall of your home with NO insulation!

wall studs

Heat bypasses the insulation in your wall cavity and transfers through the studs, allowing energy to leak through your walls.  This energy loss is known as thermal bridging, which affects New England homes in the summer as well as the winter.

energy loss in a home

  • In the winter, heat leaks through the walls where cavity insulation settles and loses the effectiveness of keeping the home warm.
  • During the summer, heat from the outdoors leaks through the studs which results in the air conditioning system working harder to keep the home cool.

Preventing energy loss is the reason why the Department of Energy recommends using foam siding with your new vinyl exterior install. With 50% to 70% of energy consumption coming from heating and cooling, homeowners can lose a significant amount of money by foregoing foam siding.

Bottom Line:  Provides real energy savings by keeping heat where it belongs, inside in the winter, outside in the summer and money in your bank account all year!

Foam Siding Protects Your Home From Moisture Damage And Your Health & Comfort

House wrap helps prevent moisture damage, but when coupled with foam siding they create an unstoppable force.

  • Moisture Management System for your home: It’s estimated that each person uses 80-100 gallons of water per day at home. Instead of that moisture becoming trapped inside the home, foam can help it escape.  Foam back siding is designed to shed water and allow walls to completely dry with a permeability rating up to 5.0, reducing the chance of mold & mildew growth in your walls.
  • Prevent Against Termite Damage:  Our foam insulation is treated with a safe insecticide that protects your home from termite damage. Most people don’t know they have a problem until it’s too late. Rest assured and have peace of mind as this product not only saves energy but it protects your home from future termite damage. In other leading brands, or when a home does not have any foam back protection, termites and other insects will create tunnels and damage the structure of your home. This treated foam doesn’t just repel the insects its kills the BEFORE they can inflect any damage.

Don’t Let Water Get Trapped In Your Walls

Moisture cannot remain inside your home for several reasons. These reasons are vital to your health as well as the overall condition of your home. Adding insulation to home reduces energy loss, but it can also create moisture problems so make sure water vapors don’t get trapped in your walls.

water damage

  • Built-up moisture inside the home can lead to mildew and mold growth. In the worst cases, black mold can form which is incredibly comprising to your health.
  • If the moisture problem is neglected, the structure of the home can suffer. This is because moisture damage leads to wood rot in the home’s frame.
  • Choose a foam with a Stay Dry technology (5x more breathable than other products) that actually releases water vapor to the outside of your home where it belongs.

Luckily, this moisture buildup is manageable with foam siding. Foam siding serves as a Type 5 water vapor by the American Society of Testing and Materials perm rating system. A perm rating of 1 is a significant vapor barrier with no breathability. Breathable foam is necessary to release interior moisture.

With a perm rating of 5, homeowners can count on our siding foam board to serve as a waterproof barrier that insulates and protects your home from moisture damage. Think of the foam siding as Gore-Tex in athletic apparel in hiking shoes, but made for your home.

Furthermore, while mother nature threatens our home with downpours and moisture from humidity, foam siding is there for your home’s protection.
