FHC Construction Sealants offer a diverse selection of 
options tailored for various construction needs. This 
lineup encompasses Structural and Non-Structural 
Silicones, Polyurethanes, Acrylic Latex with Silicone, 
and Butyl Rubber Sealants.
Structural Silicone Glazing, for instance, is a technique 
that employs silicone to securely attach glass or other 
panels to supporting frames, eliminating the need for 
external retainers or covers. These joints in structural 
silicone glazing must withstand forces stemming from 
wind, thermal expansion, and building shifts. Over 
time, this method has seen advancements in materials, 
performance, and sustainability.
Non-Structural Building Silicones, on the other hand, 
may feature low VOC emissions, making them safe 
for use in sensitive indoor settings like hospitals and 
schools.
Polyurethanes, recognized for their high-performance 
attributes, exhibit joint flexibility of up to ± 25% and 
more, rendering them ideal for various applications, 
including perimeter caulking around windows and 
doors (excluding glass). They often come at a more 
budget-friendly cost compared to silicones, providing 
excellent adhesion to diverse surfaces and the option 
for painting.
Acrylic Latex with Silicone Caulk, being water-based, 
facilitates easy cleanup. These sealants find common 
use in residential and light commercial construction 
projects, both indoors and outdoors, thanks to their 
relatively lower movement capability. They can usually 
be painted shortly after application.
Butyl Rubber Sealants excel in adhering to most 
substrates and demonstrate impressive weather 
resistance. However, due to their limited movement 
capability, they are best suited for applications with 
minimal movement, such as lap seams of metal panels 
and concealed window frame joints. Similar to the 
other sealants mentioned, Butyl Rubber Sealants can 
be painted after they have fully cured.
