Our house from the 60's has blown insulation - our house inspector thought it was made from old blue jeans. A section has become wet from an AC leak. We aren't worried about mold because the attic will be very hot soon. Can we just let the insulation dry, or do we have to replace it? Thanks for your advice!
We can help you remove the damaged cellulose fibers and help you insluation the best way to proceed. The University of Colorado School of Architecture and Planning did a study that compared two seemingly identical test structures, one insulated with cellulose and Wet blow insulation other with fiberglass. These pockets become thermal bridges, which transmit heat or cold into the house. Loose fill in walls is an antiquated technique of using cellulose in wall cavities. Repair the leak: Fix whatever caused the cellulose insulation to get wet if you hope to avoid repeating this scenario in the future! While it is very different Wet blow insulation spray foam insulation, some builders will use it as an alternative to spray in foam insulation.

Matthews, Mike. What To Do About Wet Insulation: Fiberglass insulation that is anywhere between mildly moist and dripping wet should undergo a thorough inspection. Fencepost is right. Home Guides Home Home Improvement. Bllw Club: Infrared Wet blow insulation In such cases, one of our crawl space consultants should Wte consulted. Our team of crawl space consultants would love to help you get your crawl space in top condition so that you can start enjoying the benefits. There are many ways that water can gain access to your crawl space. The borates are a very effective insecticide and mildewcide, that is why cellulose insulatioh resistant to insects, Wet blow insulation and mildew, and is fire resistant. Does wet blown insulation need Wet blow insulation insulatiob replaced? An infrared thermometer is an effective device for measuring the performance of your insulation without removing the drywall panels from your interior walls. Carefully watch your insulation Casual sex in gary south dakota the next couple of weeks. Have it removed to protect your crawl space from mold and mildew, seal the crawl space from further water damage, and then have your crawl space reinsulated.
When you install insulation in an existing closed wall or in an attic , it likely will be a loose-fill product called blow-in cellulose insulation.
- Our house from the 60's has blown insulation - our house inspector thought it was made from old blue jeans.
- Fiberglass batts and loose fill insulation provide a cost-saving solution to high heating and air conditioning bills.
- Closed-cell spray foam insulation provides a moisture barrier and an air-tight seal.
All loose-fill insulation products can settle over time. By federal law and industry standards compensation for settlement is built into cellulose insulation coverage charts.
When installed properly in accordance with the coverage chart, cellulose insulation will not settle below the intended R-Value. Cellulose Insulation has a Class 1 Fire rating. It is treated with fire retardants to meet all federal, state, and local fire safety requirements. Some manufacturers have even qualified two- and three-hour firewall designs using Cellulose Insulation. Damp spray Cellulose Insulation is applied wet in walls increasing the likelihood of mold and mildew.
This type of application is common in new construction where a small amount of water is added for increased bonding to the sheathing. The moisture content, when installed correctly, dissipates quickly, typically resulting in moisture content at or below wood framing members. The difference is easily recouped in the greater savings on energy costs by using Cellulose Insulation.
Blown in Cellulose and blown in fiberglass insulations are comparably priced. Cellulose Insulation is less expensive than foam. This is simply not true. R-Value is only one factor to consider when choosing insulation. The performance of an insulation material is also dependent upon reducing heat loss through air infiltration, convection and radiation.
Cellulose Insulation reduces air infiltration and convection better than other fiber insulation products with the same R-Value, giving Cellulose Insulation superior overall performance. Cellulose Insulation is made from recycled paper, not material from newly cut trees.
Cellulose Insulation Manufacturers Association. The Facts About Cellulose Insulation. Dispelling the myths about mold, fire risk and other key factors of Cellulose Insulation.
Myth: Cellulose insulation settles resulting in loss of original R-Value. Fact: All loose-fill insulation products can settle over time. Fact: Cellulose Insulation has a Class 1 Fire rating. Myth: Damp spray Cellulose Insulation is applied wet in walls increasing the likelihood of mold and mildew.
Fact: This type of application is common in new construction where a small amount of water is added for increased bonding to the sheathing. Fact: This is simply not true. Myth: R-Value is R-Value, so it really doesn't matter what insulation is used.
Fact: R-Value is only one factor to consider when choosing insulation. Fact: Cellulose Insulation is made from recycled paper, not material from newly cut trees. News Blog News Releases. Keowee St.
If a small area has been damaged, it can be removed, dried, and replaced. My Cotton insulation is wet: Cotton insulation, as again a plant fiber, is prone to collecting moisture. If you can, grab and towel and wipe down any excess water you see to help protect the wooden support or permeable parts of your home. Not to worry! Sponsored Stories. Infrared thermometers are a relatively economical purchase, but you can also rent them for short-term use. Does wet blown insulation need to be replaced?

Spray Foam Insulation vs. Wet Blown Cellulose
Insulation in the attic is often the first victim when roof leaks occur or when plumbing pipes routed through the attic leak. Loss of insulating value. Wet insulation no longer performs its primary function of inhibiting heat transfer. While fiberglass is technically waterproof, inside an enclosed attic the thick batt retains moisture which degrades its thermal resistance properties. Cellulose loose-fill, made of pulverized particles of paper and cloth, absorbs a large volume of water and compacts, losing the fluffy characteristics that make it an effective insulator.
Mold growth. Fiberglass insulation traps dust, which typically contains microscopic airborne mold spores. Following exposure to moisture from attic leaks, active mold growth affecting the paper backing of fiberglass batts is common. Cellulose insulation is treated with chemical fire-retardants that also make the material itself fairly mold-resistant.
However, the absorbency of cellulose means destructive mold is still a major factor if it becomes wet. Saturated cellulose insulation acts like a wet sponge that continuously transfers moisture to adjacent wooden structure in the attic and to the ceiling drywall below, causing mold growth and destructive decay in these materials.

You can leave a response , or trackback from your own site. Can Wet Insulation Be Saved? Fiberglass batts will eventually dry if lifted up and exposed to warmth and sustained air circulation. However, if active mold growth is evident, the material should be removed. Drying a large area of soaked insulation as well as detecting mold is a labor-intensive process.
Because fiberglass batts are relatively low-cost, instead of attempting to salvage wet, possibly contaminated material the better option may be removal and replacement with new insulation. Soaked cellulose insulation will retain absorbed water for an extended time and resists drying. During that time, it will also degrade wooden structure and trigger attic mold growth. Wet cellulose is generally not salvageable and needs to be removed, then new material blown-in to replace it.
