Window Sealant Compatibility & Performance

Sealant refers to a flexible material that serves the purpose of blocking dust, heat, noise, and water from entering your place of business. The sealant fills cracks, gaps, and joints in both new construction and repairs. In addition to being waterproof, they are highly resistant to weather conditions, including Arizona’s extreme summer temps.

While the term may be used interchangeably with caulking, sealants are primarily used in construction, as they provide exceptional adhesion once cured. Cure time generally varies depending on the product selected. Having window sealant installed by a professional sealant company in commercial, industrial, and municipal buildings is ideal.

Professional Grade Window Sealants

Royalty Sealants will assess your building, analyzing existing air or water leakage in window and door openings. We will look for structural cracking, failure of joint materials, and porosity of the vertical walls. That will allow us to determine the work necessary and the best materials to seal the building’s envelope.

Silicone Sealant

Among the most versatile sealants – it can be applied in various construction applications – silicone provides good to excellent adhesion and minimal, if any, shrinkage. It is a perfect option for building materials such as glass, wood, stone, metal, and brick. Silicone will bond to painted surfaces, but most paints will not adhere to silicone sealants unless using an option that can be painted, so it’s a good idea to discuss your requirements with a professional.

Polyurethane Sealant

Another equally versatile option is polyurethane sealant. Like silicone, polyurethane can be applied to various building materials, providing good to excellent adhesion and no shrinkage. The latter can be attributed to its ability to expand. It differs from silicone in that it is ideal for more extensive and irregular cracks and gaps, whether indoors or outdoors, and can be painted after it is fully cured. Additional benefits include flexibility and the ability to be applied at variable temperatures.
