Frequently Asked Questions (FAQs)

1. Is silicone caulk good for windows?

Silicone caulks are among the best caulks for sealing windows. Silicone helps provide a long-lasting seal that can be applied against interior or exterior windows and its flexible material will not crumble in hot or cold temperatures. These properties make it an excellent exterior caulk that remains flexible.

2. What silicone do you use for windows?

Siliconized latex is similar to acrylic latex but contains silanes, a type of silicone. It has many of the same properties as acrylic latex but has greater resistance to weather and creates more durable bonds. This makes siliconized latex a good choice for exterior window caulking.

3. What type of caulking is best for exterior windows?

Exterior silicone caulk is the most common type of exterior caulk because of its incredible durability and water resistance. Silicone is also a very flexible material, even after it cures, making it an ideal option for sealing drafty windows and doors.

4. Can you use silicone on window frames?

As most window frames are subjected to a degree of movement, contraction or shrinkage, it's important that the seal is flexible. In most cases, low modulus based silicone sealants, which can be used in both external and internal environments, are recommended for window frames.
