Many homes lose energy because they are not insulated to the latest standards. Because of this, they can be uncomfortable and require higher costs for heat in winter or to keep cool in summer. With the energy-efficient technology available today, homeowners who properly insulate their homes can save up to 70% of the energy used to heat or cool them by reducing living costs, creating a more pleasant living space, even by increasing the value of their property.
Where do we start?
As the heat rises, the best starting point is the roof insulation. Often, this is the easiest space to insulate because the materials can be placed on the floor of a bridge or an attic space. If your home has a basement or an auxiliary space below ground level, it is very beneficial to insulate there, either at the top of the floor or under it.
Then check your walls. Some homes will be built with hollow walls, originally designed to protect against moisture. Newly built homes are often insulated, but many cavity walls remain uninsulated and this is an excellent opportunity to improve energy efficiency: insulation materials are simply inserted into the cavity. Otherwise, if you have solid walls, exterior or interior cladding will improve the energy performance of your home and can be very cost effective as part of a renovation or repair project.
Then fill in the blanks. This assumes that windows and doors are well insulated and that any gaps in the building envelope (for example, around pipes, cables and lighting fixtures) are airtight. Even small gaps can increase heating and cooling costs and can lead to damage due to humidity or discomfort.
Finally, as part of any insulation project, it is important to provide protection against condensation caused by the “cold deck”, which can happen when there are colder surfaces in a newly insulated interior. It is also essential to ensure good ventilation, either by using windows and window frames or by mechanical heat recovery systems, so that the interior space is as comfortable as possible.
If you live in a house that may have improved insulation, this is a great opportunity to make a home that is more comfortable and cost effective.… Read More
