House Temperature and Sound Wool Insulation
Insulation is a key factory in energy saving in the home and work place. Energy waste caused by insufficient or poorly performing insulation is a key factor in causing higher energy bills. In order to mitigate this problem, it is vital to review your house insulation - as for a minimal cost you could have significant savings.
Hemp Insulation
Hemp has significantly grown in popularity of recent years. Hemp is a plant often cultivated without perticides or insecticides - which makes it a very environmentally friendly option. Fibres are teased from the plant and then synthetic binders are added to ensure flexibility and durability. Hemp wool can be used to insulate roofs, walls and even floors. Its thermal conductivity is comparable with sheep wool or cellulose wadding.
There are many advantages to using hemp wool - it is very effective at providing noise, heat and cold insulation, as well as not being hazardous to health. It is resistant to compressing and has good fire resistent properties. As it is quite rigid, it is particularly good as thermal insulation in walls and roofs.
Sheep Wool Insulation
Although sheep wool can be used in its raw form, generally it is purchased ready washed, treated and coated in a wool mattress. It quickly loses its odour. Somtimes other fibres of polypropylene polyester or resin are added. It comes in rolls of varying thickness. It is preferable to purchase it without synthetic fibres added. It can be used to insulate floors, walls and roofs.
There are many advantages to using Sheep Wool Insulation: it is not very flammable, it is able to absorb approximately 30% of its weight in moisture without wetting the fibre and losing its insulating properties. Due to its non-compacting properties, it is very flexible to use in irregular shaped spaces. Finally, it is inexpensive if you purchase directly from the stockists.
Cellulose Wadding
Cellulose wadding is 100% natural, and the most common in use for ecologic building construction. It is made using recycled paper. The manufacture of the cellulose wadding uses very little energy - significantly less than polystyrene. Boron is usually added to the recyled paper to improve its fire resistance and increase its resistance to rodents and insects.
There are many advantages to using cellulose wadding: it is ideal to use in roof spaces between rafters, and provides excellent insulation against winter cold and summer heat. It has excellent soundproofing properties in partition walls, and finally it is very easy to use due to its rigidity.
Wood Fibre
Sawdust is processed using sawmill residue. It is essential to use natural sawdust that has no synthetic materials. There are many advantages to this form of insulation, including the long durability and that at the end of their life they are fully recylcable. Tree bark can be turned into pure pellets without the need to add additional binding. It has excellent insulation properties as well as being compact and resistant to compression. It is easy to use in walls and roofs. It can be painted, papered or even rough cast. It is fire and termite resistant. When used on the ground it is very good at noise reduction.
