Acoustic insulation is more dense than ordinary bulk insulation and is specially designed to restrict the transfer of unwanted noise between floors and walls. Wall insulation is typically installed at the time of construction of the new building. Before deciding what type of wall insulation to use, consider carefully the potential impact outside noise, for example, traffic and barking dogs, might have on your quality of life.
Commercial buildings also require insulation. These often take the form of rigid panels which are fixed directly to the building framework or concrete structure using special screws. A properly insulated building will in many cases be more than twice as energy efficient as a building with no insulation. As such, insulation is usually the best investment a building owner can make towards reducing the long term energy usage and cost of the building occupants.

A well insulated home reduces energy bills by keeping warm in the winter and cool in the summer, and this in turn cuts down carbon emissions linked to global climate change.
In terms of energy efficiency, investing in high levels of insulation materials for your home is more cost-effective than investing in expensive heating technologies. It is worth taking the time to choose the right materials in the context of whole building design. Insulation materials are used in roofs, walls and floors.
Solid wall structures such as stone, cob and adobe cannot be insulated, but they have good thermal mass to compensate. Timber frame homes need wall insulation in the form of batts pre-cut sections that are designed to fit between stud walls , rolls or boards.
Other types of construction such as brick or concrete insulate with spray foam, loose fill or rolls. It is far easier and cheaper to install insulation in the walls and floors of a new build home, than to retrofit an existing home. However, insulating roofs is easily achieved in any home using rolls or bags of loose fill. Insulation materials work by resisting heat flow, measured by an R-value the higher the R-value, the greater the insulation.
This R-value varies according to material type, density and thickness, and is affected by thermal bridging, unwanted heat flow that occurs at joists, studs and rafter beams.
Conventional insulation materials are made from petrochemicals and include: fibreglass, mineral wool, polystyrene, polyurethane foam, and multi-foils. These materials are widely used because not only are they inexpensive to buy and install, but there is an assumption from the building industry that their performance ability is higher than the natural alternatives. On the downside, almost all conventional insulation materials contain a wide range of chemical fire retardants, adhesives and other additives, and the embodied energy in the manufacturing process is very high.
Natural Insulation Materials The green alternative to synthetic insulation is natural insulation. There are many different types available, including:.
It has very low embodied energy unless it is imported and performs exceptionally well as an insulation material. Thermafleece is the most common commercial brand available.
Flax and Hemp Natural plant fibres that are available in batts and rolls, and typically contain borates that act as a fungicide, insecticide and fire retardant. Potato starch is added to flax as a binder. Both materials have low embodied energy and are often combined in the same product. Examples include Isonat and Flax Cellulose A recycled product made from newsprint and other cellulose fibre. It is one of the most favoured materials of natural builders because it can be blown into cavity walls, floors and roofs; used as a loose fill; and is also available in quilts, boards and batts.
Like hemp and flax it contains borate as an additive. Products include: Warmcell and Ecocel. Wood Fibre Made from wood chips that have been compressed into boards or batts using water or natural resins as a binder. It has very low embodied energy and uses by-products from the forestry industry. Examples include: Pavatex, Thermowall and Homatherm.
Expanded Clay Aggregate These are small fired clay pellets that expand at very high temperatures to become lightweight, porous and weight-bearing. For years scientists have been discussing new approaches for greater sustainability in architecture. An energy efficient building method of the future needs to focus increasingly once more on the topographic, climatic and cultural conditions of its own environment , according to German architect Professor Stefan Behnisch.
Architects and engineers face two challenges: on the one hand, the German government is pressing ahead with its Climate Plan , by the year , to refurbish the energy system of around 90 percent of its existing buildings. This is set to further reduce carbon dioxide emissions which are produced when burning fossil fuels. On the other hand, society is making growing demands on comfortable living: the living space to be heated per person is expanding and the number of household electrical appliances is increasing.
Therefore, even more energy is required than was the case previously. One way of increasing the energy efficiency in buildings is to use insulating materials. Not only do they provide greater comfort but they also fulfil important tasks such as heat insulation, damp proofing, fire protection, and noise insulation.
Some, such as expanded polystyrene EPS have come under criticism , and others are waiting for their major breakthrough. This includes environmentally friendly insulating materials made of hemp, cellulose or wood.
Their raw materials extraction, manufacture, processing and disposal requires less energy than is the case for conventional insulating materials and they present a low risk to waterways and soil. They consist of renewable raw materials and are percent recyclable. Some outperform traditional insulating materials due to their specific properties.
The most well-known material for environmentally friendly insulation is cellulose. The flock or boards are made of crushed newspaper. In order to ensure sufficient fire protection the manufacturers add borates or aluminium sulphate. The building material, for instance, serves as roof insulation or as insulation for walls in wood frames. Wood is suitable as a sustainable insulating material for roofs and facades and also for footfall noise insulation.
The material can be processed in the form of boards, flock or wood wool. It has excellent thermal insulation.
