Air drafts through the walls cost us the most heating and air conditioning dollars, far more than a lack of insulation. Blocking them up is called Air Sealing.If a crack is meant to move, like a door or a window, then we block the drafts with weather stripping.If the crack is not meant to move, l...
Any insulation that is properly installed to provide R-20 of insulation will save just as much energy as another insulation installed to R-20. So why have I accepted to do media work for one insulation company over another?Because there are many ways that we loose energy in a home and therma...
False.
Vapour barriers, together with air barriers, prevent moisture from escaping into the walls.
In this sense vapour barriers make you more aware of the quantity of moisture you have generated in your house.
Condensation problems are caused by generating too much moisture and/or having too ...

It's become very important to understand the difference between a vapor barrier and an air barrier.
If we completely seal a polyethylene sheet on the warm side of the insulation, we call it a combined air/vapor barrier.
But it's possible to put the vapor barrier on the warm side of the insulati...
Weather-stripping is used to seal air leaks at any opening in the house that moves -- doors, windows, and traps. If you need to be convinced of the necessity of doing a good job of weather-stripping, check out Air Barriers in the search tab above -- or look at your last heating bill.

Sealing air drafts, both inside warm air escaping out and outside cold air sneaking in, is one of the most important things you can do to your house. It will both save you heating dollars and protect the structure of your house. This animation gives you a quick and visual overview of the task at ...
The smoke test described in the previous answer should be used to verify the presence of typical leaks and discover those peculiar to your own house. Before sealing, read the section on Ventilation to avoid any future condensation problems.
The leaks high in the house are not necessarily the lar...
The reality is that there is not just one good way to install windows, but there are certain principles that must be taken care of with any installation to prevent cold air or water leakage later.
Basically a window installation must shed most of the water with the siding, what does get through ...
