Sheep's wool insulation
One of the most popular examples is sheep's wool, a material that has been used for centuries in textiles and other applications. Sheep's wool does not cause itching, so it is easy and completely safe to install with no personal protective equipment.
In conclusion, sustainable rockwool substitutes such as coco coir, vermiculite, perlite, clay pebbles, Growstones, and rice hulls are proving to be game-changers in the hydroponic industry.
High water absorption rate: Due to the nature of rock wool itself, its water absorption rate is high. If improper construction is carried out in local details, it can affect the overall insulation effect, leading to problems such as wet walls.
All in all, wool is a far better insulator and thermoregulator than cotton - in both hot and cold weather - with plenty of built-in breathability to boot when compared to cotton (or any textile, for that matter).
Installing a vapour barrier is optional when utilising ROCKWOOL solutions, as stone wool insulation is water repellent. However, adding a vapour barrier can help to prevent additional moisture coming through the ceiling space.
Furthermore, it appears that mice tend to steer clear of rock wool insulation. The environment it provides can lead to blindness in mice, and the reproduction process in this insulation occurs significantly slower. Many mice born in mineral wool are blind, and their skin is often irritated.
The best non-toxic insulation is either mineral wool or foam insulation inserts.
What happens if ROCKWOOL insulation gets wet? ROCKWOOL stone wool insulation is moisture resistant yet vapor permeable. This means that in the event the insulation becomes damp or wet, the insulation can be allowed to dry out.
Can sponge be used instead of Rockwool? Pros: Less expensive than Rockwool. No rinsing or soaking is necessary with hydroponic sponges, making them easier for novices. Roots quickly absorb water, so plants develop more quickly.
Both fibreglass and mineral wool insulation can cause skin irritation so it is important to wear gloves and protection when installing the material. However, most builders say from their experience that rock wool is less itchy and less irritating during the installation process.
Robust – our solutions keep their shape, don't sag over the lifetime of a building and are resistant to rot and mould, providing high thermal performance for life4/5. Recyclable – ROCKWOOL insulation can be recycled to create new products, reducing our production carbon footprint by 10 percent6.
Whilst both materials offer strong performance, rock mineral wool is the superior option, as across almost every aspect of performance, the material delivers greater results. Most notably, rock mineral wool delivers far more effective performance regarding fire resistance.
Compared to other insulation materials like foam boards, Rockwool insulation has the best acoustic properties. Foam boards, for example, are not as effective in reducing noise because they reflect sound waves instead of absorbing them.
Thermablok® Aerogel is a revolutionary advancement in thermal technology offering the thinnest insulation available to prevent thermal and cold bridging. Classed as a Super Insulation, Aerogel has the highest insulation value of any known material with the lowest thermal conductivity value of any solid (0.015W/mK).
Off-gassing refers to the gases emitted from a product post-production, often known as Volatile Organic Compounds (VOC's). ROCKWOOL products conform to testing standards limiting the emission of VOC's.
Like rockwool, mineral wool is naturally fire-resistant, and it is often used in the same types of applications. However, mineral wool is generally less dense than rockwool, which means that it may not provide as much insulation value per unit of thickness.
Squirrels are very similar to Mice and Rats and tend to find their way in the same way but they tend to cause more damage and nest in materials like wool insulation, such as Fiberglass, Rockwool and vermiculite.
Therefore, the construction of mineral wool allows for its installation without an air gap. Leaving an air gap would only result in unnecessary cooling of the mineral wool on its outer side. It should be further emphasised that the structure of mineral wool enables it to breathe, making a ventilation gap unnecessary.
Because a vapor barrier is a low permeable barrier, it keeps moisture from passing through. This is beneficial to keep moisture away from a dry surface but will trap moisture behind it if installed on a water-damaged concrete wall, causing the wall to fail further.
Avoid contact with eyes and skin. In case of high concentrations of dust, ventilate and/or use the same protective equipment as mentioned in section 8. Relocate to well ventilated area. Use personal protective equipment as required.
