So, while #HempWool has some advantages over #Fiberglass and insulation made from #SyntheticMaterials , it is not fireproof (unlike #WoolInsulation), and requires treatment to make it fireproof. The same with mildew/mold resistance (treated with lime plaster or other materials). I've also seen "hemp wool" mixed with synthetic fibers, so that kinda defeats the purpose of using natural fibers (imho). Plus, I'm not finding any instructions on how to #DIY hemp wool (unlike wool insulation or #Oakum).
Why Hemp Wool is Gaining Traction in Sustainable Construction
Published by naturalbuildingaustralia on 14/02/2025
"As an all-natural material, it’s increasingly being considered for use in construction projects aimed at reducing environmental impact and improving energy efficiency.
Hemp wool is essentially insulation made from hemp fibers and is commonly found in eco-conscious building projects. While Harry Hemp’s blog doesn’t refer to any specific vendor or product, it highlights the general benefits and concerns surrounding hemp wool as a material in modern construction.
However, there are valid concerns, especially when it comes to untreated hemp wool. Fire safety and mold resistance are two issues that need attention before this material can be fully integrated into permitted builds. These concerns stand in contrast to the proven advantages of #hempcrete, a material that has already set a high standard for sustainable construction.
Benefits of Hemp Wool
Hemp wool, made from the fibers of the hemp plant, offers several key advantages:
- Thermal Insulation: Hemp wool provides excellent R-values, helping to regulate indoor temperatures and reduce energy consumption.
- Sound Absorption: This material excels at reducing noise pollution, making your indoor environment quieter and more comfortable.
- Eco-Friendly: As a renewable resource, hemp wool sequesters carbon during production, helping to reduce its overall environmental footprint.
- Health Benefits: Free from chemicals and toxins, hemp wool is non-allergenic and contributes to better indoor air quality.
These qualities make hemp wool an appealing alternative to more traditional insulation materials like fiberglass and mineral wool. It’s a natural option that supports sustainable living while offering practical benefits.
Challenges with Untreated Hemp Wool
While hemp wool offers many advantages, untreated versions come with their own set of challenges that must be addressed:
Fire Safety Concerns
Untreated hemp wool typically has poor fire resistance, which disqualifies it from use in many permitted builds. Building codes often require materials to meet specific fire safety standards, and without proper treatment, hemp wool doesn’t meet these requirements, potentially posing a risk to safety.
Mold and Mildew Issues
Hemp wool’s natural fibers can absorb moisture, leading to potential mold and mildew growth in environments with high humidity or poor ventilation. This is a stark contrast to hempcrete, which naturally resists mold and moisture, making it a more reliable choice for durable and safe construction.
How Hempcrete Stands Up
While hemp wool has its potential, hempcrete is already a well-established material in sustainable construction.
Here’s how hempcrete stacks up in comparison:
- Fire Resistance: Hempcrete boasts excellent fire ratings due to its lime-based composition, making it compliant with building codes and safe for use in construction.
- Moisture Control: Its unique ability to absorb and release moisture without compromising its structure makes hempcrete highly resistant to mold and mildew.
= Durability: Hempcrete is naturally resistant to pests, mold, and moisture, making it a long-lasting material in construction.
- Code Compliance: Hempcrete has undergone rigorous testing and meets ASTM standards, ensuring its reliability in meeting building code requirements.
These characteristics make hempcrete a top choice for builders looking for a safe, sustainable, and code-compliant material.
The Future of Hemp Wool
The future of hemp wool is promising, especially as advancements in testing and treatment could resolve its current limitations.
Improved Fire Resistance
Through treatment, hemp wool can be made fire-resistant, meeting the stringent requirements for modern builds. This will make it a much safer option for both builders and homeowners.
Enhanced Mold Resistance
New techniques in moisture management could prevent mold and mildew from forming on hemp wool, making it more reliable and long-lasting, even in humid climates.
Conclusion: The Potential of Hemp Wool in Sustainable Construction
While untreated hemp wool still has hurdles to overcome, its potential as a sustainable, eco-friendly building material is undeniable. As advancements in fire resistance and moisture management continue, hemp wool will become a viable option for modern construction, alongside its proven counterpart, hempcrete.
The combination of both materials offers a powerful solution, balancing insulation and structural integrity, and paving the way for greener, safer, and more sustainable construction practices. As the industry continues to innovate and test new methods, the excitement surrounding hemp wool is justified—it’s on the path to becoming a staple in eco-conscious builds worldwide."

6 Things to Know About Sheep’s #WoolInsulation
When it’s time to update your home’s insulation, consider what sheep’s wool has to offer.
By Alexa Erickson, Mar 24, 2021
"Sheep’s wool insulation uses a natural fiber base.
Among the most popular insulation materials today are #fiberglass and #rockwool (also known as mineral wool). Both consist of man-made fibers spun from, as their names suggest, molten glass or minerals such as basalt or diabase. While these insulation types are considered safe by institutes such as the U.S. National Toxicology Program and the International Agency for Research on Cancer, they do contain synthetic, hairlike fibers that can break off and become airborne during installation. They also contain #formaldehyde, which is known to release volatile organic compounds (#VOCs) into the air. Both airborne fibers and formaldehyde can irritate the skin and lungs, and long-term exposure to formaldehyde may cause some types of cancer. Even spray foam insulation can be especially dangerous due to the high level of VOCs that off-gas into the air during installation and before it cures completely.
Sheep’s wool insulation starts as sheared wool that grows naturally on sheep—often wool that is deemed too coarse to make into clothing or other fabric. It is important to note, however, that it is common manufacturing practice to treat sheep’s wool insulation with additives such as boric acid to repel insects and further reduce flammability. Ammonium sulfates may also be added as a fire retardant. So while the base material is inherently natural, the sheep’s wool insulation end product is also not completely free of toxins. Both additives are considered poisonous if ingested and can cause irritation to the skin, eyes, nose, and throat. Moreover, boric acid is classified as a reproductive toxin by the Classification, Labelling and Packaging (CLP) Regulation in Europe. [Boric acid does not pollute like #PFAS though]
When installing any type of insulation in your home, always use caution and wear the protective gear recommended by the insulation manufacturer."

fiberglass is such a cool and useful material, but the JB Weld resin I got from home depot smells like instant cancer. I use a respirator when working with it but it's so pungent that it permeates the whole area while it's curing. Any recommendations for more low-odor varieties?

I made some fiberglass 'angle iron' that will be used as braces for the top of the glider's instrument panel.
The mold was a piece of square steel tubing, well waxed.
Note that one of the fiberglass pieces is made from shorter scrap fabric, so the middle is a bit thicker because of the need for 1 inch overlap (2.5cm) of the scrap pieces.
Now I need to use a cutoff wheel to trim and clean up the parts.
Some of the paint from the square steel tube is now stuck to the fiberglass parts. Because these are internal parts, I don't care about this cosmetic flaw.

The glider turtle deck and cockpit get a few more items.
The oxygen tank is now mounted under the turtle deck. A retaining cable runs back to the rear steel carrythrough tube, and will only be used once...in the event of a crash. (Wooden 2x4's are mockups for the wing spars to ensure I am installing items with acceptable clearance.)
A two-litre water bladder hangs behind the seat pan, and the drinking tube is at a convenient location.
I still have to install another fiberglass antenna bracket under the aft end of the turtle deck.

Glider progress on closing out open spaces in the fuselage.
First photo shows the new fiberglass closeout panels I made this weekend. The new panels have bits of blue tape on them.
Second photo shows a fiberglass GPS antenna bracket near the top of the turtle deck.
What you don't see in the second photo are the wing spars, which will run across this space.
I am considering also making fiberglass shields to cover the autoconnect funnels, which are gray and located aft of the wing spar cutouts.

A home-made spring clip for small parts in the glider cockpit.
This is just several plies of fiberglass wrapped around a piece of foam that was sanded to a taper and the desired dimensions. Fiberglass can serve as a spring, but I would not use it this way where cycling fatigue is possible.

I have a new #carproject! #hotrod
I've got part of the makings for a #RatRod.
I came by a deal on an ancient #fiberglass replica of an MG TD. Guy started it 40 years ago and never did anything with it. Totally #untouched
In the garage I'm working on a 302 #Ford and I have a T5Z with a broken tailshaft housing to be repaired.
The #replica has a hefty #sqiaretubeframe frame with a #mustangII #FrontSuspension.
Already got #32Ford #wirespokewheels.
Anyone got an 8.8 #rearend laying around? -

@alf My dream #headphone would be a simple construction, avoiding plastic, glue and leather in favor of #aluminum, #wood, #alcantara and if it'd make sense maybe some #carbonfiber or #fiberglass to keep it #lightweight.
Any headphone that goes in that direction is immediately targeting a very wealthy audience though. 😝️
However, I do not long for #luxury. I am looking for #practicality, #durability, #repairability, #sustainability (and admittedly a bit of #beauty too). 🫣️🤓️ -
Pumpkin spice glass beads for pumpkin spice sunfish. For some reason, I start seeing these warmouth sunfish late summer into early fall.
I caught it on a new-to-me Fenwick FF70 7' 5-6 weight fiberglass fly rod that has the date 7/7/70 written on the rod tube. The glass beads came from a bead shop in Athens Ohio. One of the feathers came from a pheasant, and the other came from my new ratty rooster skin.

Some personal news: my wife and I have not been able to enter our apartment for more than a few minutes at a time since 12/23 due to #perlite dust #contamination which is similar to #fiberglass. Tara had to go to the #er for breathing problems and severe pain that night and we've been in hotels and hostels ever since. #advice welcome. Should we stop paying #rent? #landlord won't clean it so we're having to pay out of pocket.
