Injection Foam

Injection Foam Insulation on Florida’s Treasure Coast

Many Florida homes and buildings are constructed of concrete block walls. Within each concrete block are open cavities or cores. These empty cores allow continuous airflow into your home. Cold air easily enters in the winter and warm air in the summer, making your HVAC system work harder to maintain an ambient temperature inside your home throughout the year. The result is higher energy bills and an uncomfortable home.

Worrying about your rising energy bills should not be a part of the Florida lifestyle. Your focus should be on relaxing and enjoying time with family and friends in your air conditioned home during the hot summer. Lower your energy bills and enjoy a more comfortable home with the installation of injection foam insulation. 

What is Injection Foam?

Injection foam is a “dry” resin foam-in-place insulation product designed for the cores of concrete block walls. The liquid foam is injected directly into each concrete block where the white foam, resembling shaving cream, fills up each core. The thick, foamy consistency allows the foam to fill every nook and cranny and work its way between wires and pipes, creating a solid air seal to stop cold or hot air from entering your home. In preexisting concrete block structures, injection foam is the only and best insulation option to ensure you get a total fill throughout the block cores.

The Benefits of Injection Foam

Injection foam has many benefits for you and your home including:

High R-value, Lower Energy Bills 

Excellent thermal properties allow your HVAC system to work less to keep your home comfortable.

Seals Against Air Infiltration 

Injection foam insulation keeps the cold air out in the winter and the hot air out in the summer.

Class 1 Fire Rating 

Injection foam will not start or contribute to a fire in your home as it has high fire-resistance and does not spread flames quickly.

Environmentally Safe, No Off-gassing

Injection foam insulation does not release harmful chemicals over time into the air and your home.

Non-Expanding, Never Loses its Shape  

It hardens in place as it dries and never shifts, settles, compresses, or sags.

Reduces Sound Transmission 

Injection foam has excellent acoustic properties that help absorb sound vibrations for a quieter home.

Inhibits Insects and Pests

Injection foam insulation seals the gaps and holes where insects and pests might congregate.

Easily Installed 

Small holes are drilled into the blocks to allow the walls to be filled with injection foam, which are then patched over when completely dry.
