INSULATION MATERIALS

Standard blanket insulation is typically made up of fiberglass from silica spun. This product usually contains a phenol-formaldehyde binder (a known carcinogen). However, formaldehyde-free products have been introduced. Most fiberglass insulation has at least 30% recycled-glass content. Fiberglass insulation contains mineral microfibers which are a potential cause of respiratory problems, so care must be taken when installing it and protective equipment must be used.

Mineral wool insulation is made from either waste product from steel production or natural rocks. Mineral wool has better sound-blocking properties and fire resistance than fiberglass. Mineral wool insulation contains mineral microfibers which are a potential cause of respiratory problems, so care must be taken when installing it and protective equipment must be used.

Cotton insulation is made from post-industrial recycled cotton textiles, such as denim, with synthetic fibers added to maintain structure. Nontoxic flame retardants are added. Unlike fiberglass and mineral wool, there are no mineral microfibers in cotton insulation so the risk of respiratory problems is greatly reduced.

Hemp has been used by mankind for thousands of years. It has always been considered a valuable raw material for clothes, paper, oil & medicine. In recent years the demand for more cost effective natural construction materials has allowed for the regeneration of the hemp industry. Since 1996 the cultivation of low-narcotic hemp has been permitted again in parts of Europe. As hemp grows, it helps to restrict environmental pollution because it decomposes CO2. Uniquely, it also improves the ground soil as it leaves the ground loose & totally weed free. Because hemp matures to a height of 4m within 100-120 days, weeds have no chance to grow so no herbicides or pesticides are necessary during cultivation. The increasing demand for natural construction materials is leading to a regeneration of hemp as a natural raw material. This demand has lead to the development of regional cultivation & processing, which in turn helps to provide a product that is cost effective & environmentally friendly.

Natural wool is a better insulator than fiberglass. As an added bonus, using natural wool creates a market for sheep farmers who have struggled to make a living on sheep farming in the past. Wool becomes a more effective insulator once moisture is introduced, so it’s perfect for the Irish climate! In addition, wool breaks down formaldehyde into safe molecules so this reduces formaldehyde threat to home occupants.
