A Better Way To Insulate

Hempwool Natural hemp insulation

Hemp Fiber Insulation

HempWool is comprised of 92% industrial hemp fiber, specifically processed for this product. Hemp Insulation is non-toxic, pest resistant, and contributes to a healthy home.

In addition to the various performance factors presented above, HempWool is naturally sound absorbing. This will have the effect of increasing interior acoustic comfort, while also achieving thermal comfort. By achieving both acoustic and thermal comfort with a singular material, the resulting enclosed thermal envelope offers a multitude of benefits

Hemp is one of the most resistant insulations against rodents, mites, moths, and termites. Fiberglass, which lacks density, is a perfect nest for rodents. The strong mechanical strength of hemp fiber, and the dimensional stability of the insulation panel, prevents and deters rodents to infiltrate.

Moreover, hemp fiber has a high concentration of silica, preventing the development of moths and termites. Whereas moths love sustainable alternatives like Havelock Wool, they will not take to HempWool. In summary, the use of HempWool makes it possible to be better protected against common pests and rodents

Is Hemp Insulation Better Than Fiberglass?

Recently in the last few years Hemp insulation has made an appearance in construction industry and people want to know if its better than the traditional fiberglass.

Hemp Insulation has benefits over traditional fiberglass. Hemp insulation is sustainable and environmentally friendly to grow and produce. It can be handled without gloves as hemp does not irritate the skin or produce hazardous off gassing, and its pest resistant so that termites and rodents don't like to use it for making nests

In terms of thermal performance, both hemp insulation and fiberglass insulation are effective at retaining heat in the winter and keeping buildings cool in the summer. However, the exact thermal performance of each material can vary depending on the specific product and the application in which it is used.

Since hemp insulation is made from the plant's fibers, it’s completely natural and free of chemicals. But why does this matter?

  • Look for insulation with an Environmental Product Declaration (EPD) or Health Product Declaration (HPD).
  • Insulation made of plant fibers, like hemp, is an excellent choice for those who want a natural and sustainable product.
  • Avoid products treated with formaldehyde or other chemicals.
  • Consider insulation with a low VOC (Volatile Organic Compound) rating.

Hemp is an excellent choice if you're looking for a sustainable insulation option. The plant grows quickly and doesn't require much water or chemicals to thrive.

3. Hemp Insulation Is Effective in All Seasons

One of the best things about hemp insulation is its effectiveness in any season. It’ll keep your home warm in the winter by trapping heat inside.

And in the summer, it’ll keep your home cool by reflecting heat away. This is thanks to the plant's strong fibers, which are excellent at trapping heat.

As a result, you'll be able to save money on your energy bills all year round. Plus, since it's effective in hot and cold weather, you can use it no matter where you live.

4. Hemp Insulation Does Not Irritate the Skin

Another great thing about hemp insulation is that it doesn't irritate the skin. Some types of insulation, such as fiberglass, can cause skin irritation.

Here's a video that describes some of the benefits of hemp in construction:

5. Hemp Insulation Regulates Humidity

Another great thing about hemp insulation is that it helps regulate humidity levels. According to this study published in 2015, the plant can absorb moisture from the air. As a result, it helps keep your home's air dry and prevents the growth of mold and mildew.

Plus, this insulation can be a lifesaver if you live in an area with high humidity levels. By regulating the humidity levels in your home, you'll be able to prevent health problems such as asthma and allergies. In addition, you'll be able to save money on your energy bills. This is because high humidity levels can make your air conditioner work harder, which leads to higher energy costs.

Pro Tip: Besides using hemp insulation, here are a few ways to keep your home's humidity levels under control:

  • Use a dehumidifier: A dehumidifier is a device that removes excess moisture from the air. This can help keep your home's humidity levels under control and prevent the growth of mold and mildew.
  • Ventilate your home: Another way to reduce humidity levels is to ventilate your home. You can do this by opening windows and doors or using fans.
  • Use an air conditioner: If you live in a hot and humid climate, using an air conditioner can help keep your home's humidity levels under control.

6. Hemp Insulation Reduces Noise Levels

Another benefit of using hemp insulation is that it can reduce noise levels. This is due to the plant's strong fibers, which trap sound and prevent it from echoing around your home.

If you live in a busy area or have noisy neighbors, this benefit can be a godsend. By reducing the amount of noise in your home, you'll be able to relax and enjoy your downtime much more.

Besides, reducing the noise levels can help you concentrate and be more productive if you work from home. Also, if you have young children, reducing the noise levels in the home can assist in everyone having better sleep.

7. Installation Is Quick and Easy

Another great thing about hemp insulation is that it's quick and easy to install. Unlike other types of insulation, you don't need any special tools or equipment.

In addition, there's no mess or hassle involved in installing hemp insulation. So, you can get it done quickly and without any fuss.

If you're not comfortable installing insulation yourself, you can always hire a professional. This is an excellent option if you want the job done right and don't want to worry about it. Nonetheless, installing hemp insulation is a relatively easy task that most people can do themselves.

8. Hemp Insulation Saves on Energy Costs

One of the best features of hemp insulation is that it can help you save on your energy costs. This is because the plant has excellent thermal properties, which means it can keep your home warm in the winter and cool in the summer.

According to a 2015 study, the thermal conductivity of commercial hemp insulation falls in the 0.038-0.043 W/(m∙K) range, making it an excellent insulator. Therefore, you won't need to use as much energy to heat or cool your home, which will help save you money on your energy bills.

9. Hemp Insulation Is Pest-Resistant

Another great thing about hemp insulation is it's pest-resistant. This means that you don't need to worry about rodents or insects invading your home and causing damage. With this insulation, you can rest assured that it’ll protect your home from pests.
