One of the best ways to improve your home’s energy efficiency and prevent water infiltration and drafts is to make sure your windows are well sealed. One way to do this is to apply sealant to any areas that may not be airtight.
In order to make the perimeter of the windows 100% airtight, it’s important to choose a sealant designed specifically for that purpose.
In this article, find out which features make for a good window and door sealant and which Adfast products are perfectly suited for the job.
Features of the best window sealants
Before going to the hardware store to buy a sealant cartridge, it’s important to know the characteristics and properties that make a sealant product effective at caulking doors and windows.
The components of sealants vary greatly, making some products much more suitable for this use than others.
Adhere well to various types of building materials
Windows and the walls that hold them can be made with many different materials. A good window sealant must therefore be able to adhere solidly to a variety of bases, such as glass, plastic, aluminum and masonry.
Good resistance to UV rays
Prolonged exposure to UV rays can affect the performance of some silicone sealant products. These rays can cause discoloration, loss of flexibility, and even cracks in joints made with sealants that are susceptible to them.
Remain flexible even at low temperatures
Windows are regularly subjected to hostile weather conditions. In North America, temperatures can drop well below freezing, which can reduce the flexibility of some sealants. For best results in all seasons, it’s important to choose a product that will remain flexible even when subjected to freezing temperatures.
it is recommended that you choose a non-corrosive sealant in order to avoid damaging the metal components of your windows and building. That way, you avoid the risk of the sealant causing rust on your house.
Offered in a variety of colours
Some sealants can’t be painted because paint doesn’t adhere to their surface. It’s best to try to find a sealant with a colour that blends well with the tones of your windows and building.
