How often do you think about the insulation in your home? Yet, it plays an important part in maintaining your home’s comfort and energy efficiency. Insulation should be dry, and if it gets wet, it can become compromised. Things like roof leaks, pipe bursts, floods, or condensation can all cause wet insulation. Wet insulation can lead to mold growth, increased energy costs, and even structural damage.
Gold Star Insulation has helped thousands of homeowners across Northern California identify and replace wet insulation, and we want to help homeowners. Here’s how moisture affects your insulation:
Primary Concerns of Wet Insulation
When insulation becomes wet, it loses its ability to regulate temperatures effectively. This can create a whole series of other problems, including:
- Mold growth: Wet insulation provides the perfect environment for mold to thrive. Mold can lower indoor air quality and create serious health risks.
- Reduced insulation effectiveness: Insulation’s R-value, which measures its thermal resistance, goes down significantly when it’s wet. This leads to higher energy bills and less comfort.
- Structural damage: Moisture weakens structural parts, like wooden beams, drywall, and ceilings. This means you could have costly repairs if there’s prolonged exposure to moisture.
When moisture reaches different types of insulation, it can affect their R-values in different ways. Here are the main types of insulation and their effects:
- Fiberglass: Moisture changes the displacement of air pockets, which reduces its insulating properties.
- Spray foam: While it resists water, it may require replacement if water goes through its barrier.
- Cellulose is a highly absorbent insulation that is prone to mold growth. It often needs full replacement after exposure to water.
What To Do If Your Insulation Is Wet
You take different steps to address wet insulation depending on its type and how badly exposed it is to moisture.
- Fiberglass insulation: For minimal moisture, remove and dry small sections thoroughly. If the material remains damp or shows signs of mold, you’ll need to replace it.
- Spray foam insulation: Inspect for water getting through the barrier. If the damage is minimal, drying may be sufficient. Call a professional for inspection and replacement if it’s been exposed to a significant amount of moisture.
- Cellulose insulation: Because it absorbs moisture, cellulose insulation must be removed immediately to prevent mold growth.
If you think your insulation has gotten wet, the first thing to do is find and stop the water source. Then, make sure you have good ventilation during the drying process to help dry it out and get rid of all excess moisture. Finally, it’s best to consult a professional for an inspection to evaluate the damage.
Do You Always Need to Replace Wet Insulation?
Knowing if you should replace your wet insulation depends on a few factors, like the material type, how much water exposure there was, and how quickly the issue is addressed.
If the water damage is severe, it’s usually best to get a full replacement to give you peace of mind that your home is safe and energy-efficient. Sometimes, if the area that got wet is small, you may be able to dry and salvage it. This should always be determined by a licensed insulation contractor. A professional inspection helps you make sure all compromised materials are identified and prevents future issues like mold or reduced insulation performance.
