BLANKET FILL INSULATION

Blanket fill insulation also known as a 'loft roll'. It helps to retain heat in your home which would typically escape through the ceiling. Blanket fill insulation usually comes in roolls and batts. While rolls can be unrolled into place, batts can be installed between rafters for even more effective insulation. It can be fit between studs, joists, and beams, and usually comes pre-measured to suit standard stud and joist spacing such as 400mm or 600mm centres. In its roll form, it can also be rolled over ceiling joists, which prevents heat from being lost via conduction. Blanket insulation can also be used as acoustical insulation for retrofitting warehouses and other such commercial buildings, as well as thermal insulation for areas inside the home (attic spaces). When used at ceiling level it is usually laid in two layers, with the first layer between the joists and the second layer over, and at right angles to the joists. It comes in various thicknesses available, including 100mm, 150mm, 200mm and 270mm. Blanket fill insulation is made by  Isover, Ursa, Superglass and Thermafleece.

TYPES OF BLANKET FILL INSULATION

Generally speaking, blanket fill insulation can be divided into 3 main categories named as Mineral wool, Glass wool and Sheep's wool. Different ingredients are used in the production of these wool. In fact, 2 of them - mineral wool and glass woll are the same, they are just made up of different minerals. One is made of stone (stone wool) and rocks and the other is made of glass. Both of these insulation types operate on the insulating property of air trapped between the fibers. 

MINERAL WOOL

Mineral wool insulation is also referred to as stone wool. It is made from a range of raw materials like rock and stone, and the process for this is very similar to the glass wool insulation process. Mineral wool is made by melting the raw material, which can be stone (such as basalt), at very high temperature, spinning it like cotton candy to produce very thin fibers, coating those fibers with a binder to hold them together, and forming it into the insulation batt or boardstock material to meet specific product needs. The mineral wool is then usually packed into either slabs, rolls, or batts. Mineral wool is highly fire resistant, which has long made it an insulation material of choice in many commercial buildings. Mineral wool is a heavier and more dense insulation material than fiberglass, giving it better sound-control properties and more effectively restricting air movement through it.  Since stone wool is three times denser it is also heavier.

GLASS WOOL

Glass wool sometimes referred to as fibreglass insulation made of recycled glass fragments and pure sand. It is available in the shape of blankets or sheets. Being ‘made to measure’, the material’s extremely easy and efficient to install. Glass mineral wool is also breathable, helping to reduce the risk of condensation in the building. Glass wool can be supplied as either slabs or rolls depending on how the product will be handled and installed. Glass mineral wool is usually laid at ceiling level as a common loft insulation solution. It can also be fitted between rafters, as part of a loft conversion project, to provide both thermal and acoustic comfort.

SHEEP WOOL

Sheep's wool is a natural material obtained from sheep and other animals, including cashmere and mohair from goats. Because it is a natural fibre, sheep's wool insulation is also biodegradable, making it a more sustainable choice than synthetic insulation options. If you're looking for an environmentally-friendly way to insulate your ceiling, sheep's wool insulation is a great option. Wool insulation causes no issue to the health of people or the environment, it does not require any protective wearing while installation like fibreglass insulation. Sheep wool is nature's most effective insulator and has a crimped nature, which helps to form millions of tiny air pockets while packing or bonding wool fibre to trap air. The environmental benefits of sheep’s wool insulation are many. Each kg of natural fibre product locks up about 2-3 kg of carbon dioxide which helps remove CO2 from the atmosphere. Thermal Conductivity of sheep wool insulation is between 0.035-0.04 W/mK which makes sheep wool a better insulator. Sheep wool insulation can be used throughout the entire house from loft, floors, external walls and internal walls. Sheep wool will keep its insulation value even if moisture is present in the building. Sheep's wool is hygroscopic, so it can absorb around 25% of its own weight in moisture before its thermal efficiency drops. This ability to absorb water helps control humidity levels and reduces condensation within your home.
