Insulation
Unless a house has suitable loft insulation up to 60 percent of heat from a property can be lost through the roof. As energy is becoming an increasingly expensive commodity it is obvious that this is a lot of money that is getting wasted not to mention the environmental toll of increased energy demands. Loft insulation acts like a blanket to trap rising warm air which without the loft insulation would escape through the roof. The great benefit of loft insulation is that it is relatively inexpensive for the immediate benefit that is gained. Another benefit is that loft insulation can be purchased at most major DIY stores. Why not try ordering loft insulation online and then letting the store deliver it for you. This will save you a lot of hassle and most retailers will deliver for free or at very reasonable rates.
While there are many forms of loft insulation, the one that is most common and that people identify with when thinking of loft insulation is the wool type material that is brought as a large roll. This type of loft insulation is the most commonly used method in the United Kingdom and is known as a ‘quilt’. The quilt comprises usually of fibre glass matting or mineral fibres which have a meshed structure allowing air to become trapped. Air is a relatively poor conductor of thermal energy so this rapidly slows down the rate at which heat is lost through the loft your house.
Another area which is prone to energy leakage is around doors. This can be offset by using draft excluders which act as a barrier to the movement of warm air through any gaps.
More Info
| Insulation is a general term that may refer to thermal or electrical insulation and can be defined as the use of proper dielectric or insulating materials for resisting the flow of electric current or heat. Electrical insulation is accomplished by the use of dielectric materials which have atoms with tightly bonded valence electrons. Electrical insulation is carried out so as to ensure the safety of human beings interacting with them and also to support current carrying conductors used in transmission without passing current through them.
Some typical examples of insulators are glass, porcelain, and Teflon and all these are used in various industries for insulating purposes. In addition to these materials, there are many artificial polymers and plastics available which can be designed to have insulating properties as required for heavy industries. In theory any material that does not conduct electricity can be termed as an insulator. Electrical current flow occurs due the availability of states into which the electrons in a material can be excited or through the movement of ions. The absence of both will make the material an insulator. However the major factor to be considered in the design of insulating systems is the electrical breakdown voltage if the material used. The breakdown voltage can be defined as that particular voltage level above which the material loses its insulating property and starts behaving as a resistor, the results of which can be catastrophic and unpredictable. Thermal insulators are those materials that are used to restrict the flow of heat and are carried out generally for maintaining a particular temperature at a place with minimum energy intake. The most common application of thermal insulators is in refrigerators, freezers, air conditioners, domestic flasks and other kitchen utensils or devices. |
