One solution is to use stone wool insulation, which offers excellent drying potential and does not promote mold growth.
Fiberglass insulation is constructed of tiny shards of glass that form pockets to trap air and help restrict the transfer of heat. Its naturally mold resistant in that the material itself is not a food source for mold.
The best types of insulation to prevent mould include: Sheep's wool insulation, which can be one of the best types of insulation for preventing mould, as it has natural damp-fighting properties.
Nonporous materials such as plastic, metal, and glass are less likely to support mold growth but may do so if organic material is available in the dust or dirt coating these materials. Uncoated masonry is also less likely to support mold growth but may do so under special conditions.
Although fiberglass insulation is generally mold-resistant, mold can still grow on dust, dirt, or other organic debris that may collect on its surface.
The best way to remedy mold on insulation is by prevention. One way to prevent mold on insulation is proper ventilation. Good air circulation in an insulated area prevents moisture buildup that can lead to condensation. Sealing leaks in the building is another way to prevent mold.
There are only a handful of mold release agents that DIY fiberglass technicians commonly use: paste wax, drugstore hairspray (yes, hair spray-that horrible liquid plastic stuff used for producing rigid quaffs of the early 1960s), and poly vinyl alcohol (PVA), a sort of water-soluble liquid plastic.
Options such as porcelain tile, vinyl plank, and engineered wood are highly recommended by Buffalo Restoration for their durability and resistance to moisture. These materials are easy to clean and maintain, making them ideal for areas susceptible to water exposure.
There is a silver lining: you can't eliminate mold, but you can discourage its growth. By taking steps to make your home mold resistant, you'll avoid the headaches of remediation and repair, as well as the potential health problems mold can cause.
Mold hates light. Other than moisture there's nothing mold loves more than dark places. An easy prevention against mold growth is opening your blinds and shades. If it's warm enough out, open the windows.
You can get rid of mold by mixing bleach and water. First, mix one gallon of water with one cup of bleach. Then, use a spray bottle to spray the mixture onto the moldy insulation. Let the mixture sit for about 10 minutes, then rinse it with water.
For this reason, we highly recommend Suretherm Anti-Condensation Paint. Suretherm helps prevent the route cause of the problem - the moisture! Suretherm Anti Condensation Paint is an internal water-based emulsion that is specifically designed to help deal with internal mould and damp caused by condensation.
If water can't get inside the walls or into the masonry and timbers, then mould will find it difficult to survive without the moisture it needs. In conclusion, the question 'will external wall insulation stop mould' can be answered with a resounding yes.
Mold does not grow directly on insulation because the insulation is not its food source. However, when your attic or crawl space is attacked, then it will spread to the insulation. And as such, it will start to grow on the insulation.
Thanks to its cell structure, FOAMGLAS® cellular glass insulation is completely waterproof and vapour tight. Leaks are easily detected as water cannot penetrate the system, and the insulation does not absorb water.
Many of us know what causes mould; when moisture is trapped in the rooms of you home. Sometimes, there is insufficient insulation in the walls, so mould grows. However, not many people realise that additional insulation isn't always the answer. In fact, too much insulation can be the secret cause of mould.
Because most synthetic fibers, such as acrylic, polyester and nylon, are resistant to mildew, clean fabrics of these fibers will not support mold growth.
In short, the answer is yes. Older buildings are more likely to have mold issues. Newer homes, however, can have mold problems that are just as serious if the owner does not implement proper prevention strategies.
As such, stone wool insulation will not contribute to the growth of mold, mildew, bacteria or rot. It will instead resist mold, helping to preserve indoor air quality (IAQ) for occupants of the home or building.
Mold prevention
DO put exhaust fans in kitchens and bathrooms. DO clean your bathrooms with bleach and other mold killing products. DO add mold inhibitors to wall and ceiling paints before application. DO inspect hoses, pipes and fittings to insure leaks won't cause dampness.
There are, however a number of surfaces where mold will not grow. Treated surfaces and drywall have been found to resist growth, even when wet.
To release the resin from its mold, use Vaseline. Apply it over the mold before adding the epoxy resin. This mold release for epoxy prevents the resin from sticking to the mold.
Yes, there is a method to avoid the chance of sticking on mold initialization. In a word…PVA. Polyvinyl alcohol (PVA) is a parting film which forms a physical barrier between the mold and the part. PVA has been around since the beginning of the fiberglass industry and certainly is not considered new technology.
