If your attic is said to be two of the weakest places in your thermal insulation system along with the roof, it is possible that many may not believe. Poor (or absent) attic insulation will account for up to 15 per cent of your house’s total energy loss, according to statistics. Insulating an attic that is generally unheated is vital in the process of saving energy at home. read the article
What is your building’s attic, really?
Attic is defined as the space enclosed by the wall of the building and is located directly beneath the roof. Since this is an area not generally continuously occupied by anyone (except in special designs and home modifications) it is unheated. Depending on the volume of space available, some components of utilities such as water heaters, hot water storages, air conditioning and heating air ducts and also storage of goods may be located here. The roof and floor are generally insulated but more often than not inadequately.
Heat loss areas inside an attic
Researchers have identified some major points of heat loss. For instance;
Access at the Attic
Poorly erected hot / cold air canals and,
Poor insulation and plumbing in hot water tanks
The silver lining in the whole issue is that the easiest to deal with isolates from an old or new building attic isolation. And in most cases, as a DIY project maybe during a weekend, semiskilled amateurs can perform it!
Types of insulated attics
Commonly used insulations from the attic are as follows:
Insulation with cellulose-loose filling
Insulation with cellulose-Stabilized Insulation
Insulation of fibreglass and mineral wool-loose fill
Insulation of fibreglass and mineral wool-batts
Expanded insulation of polystyrene or phenolic foam-rigid boards
Cellular Foam Insulation-butyl and nitrile rubber foam sheets etc.
