I have a small gap (2mm) under the window sill that is causing some draft to come inside the house. I have attempted to correct this using the Ge Silicone Caulk, but the draft continues to come in.
So I am going to now try the gap and crack sealant in that area? The name of the product is Gaps and Cracks Insulating Foam Sealant and it is available at home depot.
How can I stop the draft from coming in? Is this the right product that I should use?
The temperature outside is 20 degrees F.
