Is Spray Foam Insulation Waterproof? What Woodstock Homeowners Should Know

The weather in Woodstock mirrors the rest of Georgia. Temperature fluctuations and storms are commonplace. Many homeowners keep this fact in mind during new construction and home improvement projects.

So, when it’s time to install new or replacement insulation, it’s natural for many to choose a material that doesn’t just keep conditioned air in but can also survive even in the event of a flood.

Spray foam insulation is the highest-rated form of insulation and generally the most expensive. Is spray foam insulation waterproof, though? The best attic insulation company in Woodstock will cover all you need to know about spray foam insulation and water protection in this post.

What Is Spray Foam Insulation?

Spray foam insulation is the material you get from the mixture of polyol resin and isocyanate. Spray foam installers mix these chemicals and spray them out of a container around the surfaces they intend to insulate.

The chemical comes out as a liquid. However, it forms a semi-solid expanding foam as it reacts with the air, providing the insulation you need.

The Types of Spray Foam Insulation

Spray foam insulation comes in two variants: open cell and closed cell spray foam insulation.

Open cell spray foam insulation is generally more flexible and softer. It expands quickly, shortening the installation time significantly. It’s also easier to remove when you need to take out the insulation.

Closed cell spray foam insulation is a lot denser because the cells are closed off completely. It’s stronger and has some of the highest R-values you’ll ever see among insulation materials.

However, the denser nature of closed cell spray foam insulation means it takes longer to install. You’ll also need a lot more chemical to achieve the right level of insulation. Thus, it’s generally more expensive.

Is Spray Foam Insulation Waterproof?

In a word, yes. But only closed cell spray foam insulation. The highly dense nature of closed cell spray foam insulation means it doesn’t allow water to get through easily. The moisture resistance of spray foam insulation makes it a fantastic choice for high-humidity areas like Woodstock, GA.

However, you won’t get waterproof insulation just by using spray foam insulation. Other factors that can influence the waterproof properties of spray foam insulation include the following.

Level of Thickness

The thickness of the insulation is a major factor when it comes to the level of water resistance you can expect from your closed-cell insulation. The thicker the insulation, the higher its ability to keep out water.  

There’s no hard and fast rule for the level of thickness to aim for. However, the general rule of thumb is to aim for three inches of insulation on walls and five inches on walls.

Your insulation crew will recommend the right level of thickness based on your home’s peculiar situation, but it’s always best to ensure you meet the minimum requirements first if you want to enjoy the water-repellent features of spray foam insulation.

Quality of Installation

Professional installers of spray foam insulation do more than just point the nozzle to the wall or ceiling. They know the right ratio to go with when mixing the chemical and how much they need to express to reach the right level of insulation for your space.

They also know how to cover seams and penetrations properly. Those areas where pipes and wires enter and exit your home are usually loopholes in any poor installation work. Poor quality work can affect your insulation’s water resistance qualities.

Presence of Other Gaps and Voids

The waterproofing capabilities of spray foam insulation will not matter if your roofing is severely compromised or if you have an unfinished or untreated basement and crawlspace. The thing about moisture prevention is you can’t afford to neglect a possible source of moisture, no matter how little you think it is.

Why Waterproof Insulation Is So Important

Seeing that the answer to, “Is spray foam insulation resistant to water?” is, “Yes, if you use closed-cell spray foam insulation,” you may be wondering if you really need to worry about waterproof insulation. After all, you can get most of the main benefits of spray foam insulation with the cheaper open-cell option.

However, you’re doing the right thing by thinking about choosing waterproof insulation. Research by Statista.com, shows that floods cause billions of damage across the U.S each year. Residents in Woodstock and the rest of Georgia are no stranger to such types of damage.

Waterproof insulation helps protect your home from moisture damage, especially for the more manageable cases of flooding. Prevent moisture intrusion can save you from the dangerous impact of mold growth.

Additionally, waterproof insulation means you won’t have to worry about removing your insulation material after every storm. Materials like fiberglass lose their effectiveness when they get wet. For closed cell spray foam insulation, the wetness will never get into the core of the insulation.

This can save you significant sums over the years as you won’t have to worry about replacing your insulation or, worse, going on to live without proper insulation a few months after spending significant sums on the insulation process.

Finally, waterproof insulation is highly versatile. You can use it everywhere around your home to the same fantastic results. So, you don’t need to worry about having separate insulation for your basement or attic space.

How To Fix Condensation in Your Woodstock Attic

Homeowners in Woodstock dread seeing any moisture in the attic, and for good reasons. First, no one wants the hassle of fixing roof leaks. Secondly, moisture in the attic often means mold growth and other structural issues.

However, that attic moisture may not be due to a leak in your roofing. It could be condensation. Condensation in attic spaces is still a major issue that needs urgent attention. The fallout might not be as instant as with a roof leak, but it can be highly destructive.

In this article, the best attic insulation company in Woodstock, GA, will discuss all you need to know about attic condensation and how you can fix it.

What Is Condensation in the Attic?

Your attic isn’t just a space to dump your outdoor gear, seasonal decorations, and everything else you want to keep out of sight. It plays a significant role in keeping your home comfortable. It is the barrier between your conditioned living spaces and the roofing, helping shield you from the year-round temperature fluctuations outside.

Attic condensation occurs when damp air enters the space and can’t escape. As the air in the attic cools, the moisture in the air will turn to liquid. In the winter, the liquid can turn to frost. The resulting moisture will accumulate on beams and other parts of the attic.

Water damage will follow if you don’t address the issue for long periods. Attic condensation can happen all year, but it’s worse during the colder months when the outside temperatures are cold, but your home is warm.

What Causes Condensation Attic Spaces?

Some of the main causes of attic condensation include the following:

  • A leaky roof. Leaks in your roof will leave the air in your attic permanently damp due to the steady water intrusion.
  • Leaky pipes. Leaking plumbing in the attic will have the same effect as a leaky roof.
  • Poor insulation. Inadequate insulation between the attic and the lower living area will lead to air leakage into the attic space.
  • Blocked vents. Storing too many items in the attic can block vents and hamper air circulation in the space.
  • Poor appliance venting. Some people have bathroom vents running directly into the attic, increasing the amount of hot and humid air entering the space.
  • Inadequate number of attic vents. If you don’t have enough attic vents, moist air will remain trapped in the attic instead of allowing it to circulate and flow back outside.

The Top Signs of Condensation in Attic Spaces

Condensation in the attic can go unchecked for a while because the signs don’t become apparent immediately. Some of the signs you can expect to see when it starts manifesting include:

  • Musty smell in the attic
  • Watermarks on beams or any other surfaces
  • Damp insulation
  • Condensation on attic windows
  • Visible rust or condensation in the ductwork

You should make it a habit to visit your attic space periodically. It’s the best way to identify any issues before they get out of hand. Ideally, you should always visit your attic on chilly winter and rainy summer days. Those are the best days to see if you have condensation up there.

How To Stop Condensation in the Attic

The best way to stop condensation in the attic is to identify the cause and then try to address it. You may need to hire an expert to help with the analysis and recommendations. Some of the most common approaches to stopping condensation in attic spaces include the following.

Reduce Clutter in the Space

The attic is the perfect storage space for many homeowners in Woodstock, GA. However, as you load up the space, be careful to avoid blocking any vents. If you can currently see blocked vents in the attic, you can stop your moisture problem by removing some of the items you’ve stored up there to create more space.

Add More Vents

If you don’t have blocked vents but condensation is still a problem, you should consider adding more vents to increase airflow across your attic. Doing this will further reduce the amount of moist air that remains stuck in the attic.

However, adding more vents is a significant home improvement project. You should only consider it if other options here haven’t worked.

Reevaluate Your Bathroom or Appliance Venting

The local codes for Woodstock, GA, require venting your bathroom or appliances away from the attic. If yours vent into the attic, you’ll need to hire a contractor for vent rerouting to prevent attic condensation.

Fixing this issue now will also save you from inspection failure when it’s time to sell your property.

Improve Your Insulation

Do you have old insulation between your attic and the living areas? Perhaps you never had enough insulation in the first place. Fixing your insulation problems can help reduce the amount of warm air entering the attic and worsening your condensation problems.

However, it’s also possible to over-insulate an attic space. Therefore, it’s best to hire an experienced insulation company to help you strike that perfect balance to address your current condensation issues and avoid creating a new one.

Install a Dehumidifier

If you’re not quite ready to permanently fix your condensation issues, you can install a dehumidifier in the attic space to help keep it dry in the short term.

Dehumidifiers help remove excess moisture in the air, reducing the probability of condensation forming around your attic to the barest minimum. Be sure to choose the right size of dehumidifier for your attic space if you want this temporary fix to work.

8 Attic Vent Types for Your Home in Woodstock, GA

Attic ventilation systems serve an essential purpose. They draw fresh outdoor air into a building while allowing stale, musty air to escape. Yet many Woodstock residents seem unfamiliar with how attic ventilation works or the attic vent types used in residential architecture. Anthem Insulation & Home, Woodstock’s best attic insulation company, lists some vent types below. 

What Is an Attic Vent?

Most attic ventilation systems consist of intake vents and exhaust vents. The intake vent pulls fresh air into the building. That air will circulate throughout the home. 

The exhaust vent releases old, warm air as it rises into the attic. This release makes room for the fresh, crisp air from the outdoors. Most Woodstock homes feature one of two vent varieties: active or passive ventilation. 

Ideally, each attic should feature one square foot of intake and exhaust ventilation for every 300 square feet of attic space. Proper ventilation protects a home’s structural integrity, especially for the roof. It can reduce energy costs and improve indoor air quality. 

Passive Attic Vent Types

Passive ventilation requires less maintenance of the two. The forces of nature keep air circulating through passive vents. As wind moves into the vent, it enters the building. The warm, stale air escapes in turn. Some examples of passive attic vent types include:

  • Box vents: Contractors can install small, square vents along the roof’s surface. They work best for roofs with numerous valleys and angles. 
  • Cupola vents: This vent type often costs more than other options. Although it offers excellent ventilation, most homeowners choose these structures for their architectural aesthetic rather than their practicality. 
  • Soffit vents: These vents are versatile, subtle, and effective. A contractor can install them on almost any type of roofing. 
  • Gable end vents: Only homes with attics housed by gabled peaks can have gable end vents. Homeowners install them on either end of a gabled peak to increase attic airflow. 

Active Attic Vent Types

Many homeowners prefer active ventilation due to its consistent motorized operations and increased effectiveness. However, these systems may require more maintenance. Some examples of active vents include:

  • Baffled ridge vents: These vents run the length of a peaked roof ridge. The warmest air can escape through them as they replace it with cool, fresh air. 
  • Turbine vents: Turbine models require a breeze to function, so they aren’t the most effective vents. However, they can reduce a home’s roof emissions. 
  • Hand-wired powered vents: These small, circular vents use electricity to power their operations. Homeowners use a humidistat to control its functions. 
  • Solar-powered vents: While solar-powered options don’t use electricity to operate, they will cease functions to recharge their power supply. This results in higher energy costs as the HVAC system must work harder.
