Draft Proofing: Weather Stripping and Caulking



Weather-stripping is used to control air leakage at joints where two surfaces meet and move relative to each other such as doors, windows, and attic hatches. A proper weather-stripping job requires that you select the correct material, adequately prepare the surfaces to which the weather-stripping will be applied, and properly install the material.

Selection of Weather-stripping

Different types of weather-stripping materials are commonly available. The weather-stripping you choose for a particular application should:
• Provide an effective seal
• Be durable
• Be relatively easy to install
• Have an acceptable appearance



Caulking is used to reduce air leakage where two surfaces meet, but do not move. Although the application of caulking may require a little more effort and skill than weather-stripping, it is just as important in cutting heat loss from your home.

A proper job of caulking requires that you:
• Select the correct type of caulking for each job;
• Properly prepare the surface to which the caulk will be applied;
• Properly apply the caulking
If any one of these aspects is ignored, the effectiveness of the caulking job will be jeopardized

Selection of Caulking

Many homeowners have unfortunate experiences when they first try caulking because they purchase an inexpensive or inappropriate caulking compound. These caulking materials might be effective at first, but more often than not, they fail very quickly and will be a waste of time and money. Be sure to select a good quality caulking material that is well suited to the task.


By just caulking and weather stripping your home you can reduce the amount of air leakage in your home. You can read in more detail about draft proofing your entire home at Efficiency NS
