Buying Guide
Choosing the right caulking for interior windows is important for maintaining energy efficiency and preventing drafts. The right product can also improve the appearance of window frames and reduce noise. Understanding key factors will help you select the best caulk for your needs.
Type of Caulk
Different caulking types are suited for interior window applications. Latex, silicone, and hybrid caulks each have specific benefits and limitations. Consider which type offers flexibility, adhesion, and ease of use for your project.
