Foam is one of those fascinating materials that hides in plain sight—something you encounter every day without realizing how much potential it carries. From the cushion on your chair to the packaging that protects your favorite gadgets, foam is everywhere. But what exactly is it? At its core, foam is a structure made of gas bubbles trapped in a solid or liquid matrix, giving it that light, airy, and sometimes spongy quality we all recognize. In the world of design and sculpture, this unique structure becomes more than just practical—it becomes a canvas for creativity. Foam can be rigid or flexible, dense or feather-light, smooth or textured, making it a material that bends to the imagination of artists, builders, and innovators alike. This section, What is Foam?, is designed to peel back the layers of mystery surrounding this versatile medium. Whether you’re curious about how it’s made, why it behaves the way it does, or what makes it so valuable across industries, this is your doorway into understanding foam in all its forms.

This comprehensive guide explains the science, benefits, and best techniques, showing how foam rolling supports both body and mind for long-term well-being.
What is Foam Padding? Comfort, Safety, and Performance Explained
Foam padding is the hidden layer that shapes comfort, safety, and performance in our daily lives. From cozy mattresses to protective helmets, it cushions, supports, and protects in ways we often overlook. This in-depth review explores its history, science, uses, innovations, and future, revealing why foam padding is more than material—it’s an essential modern marvel.
What is Foam Board? A Complete Craft and Construction Guide
Foam board is a versatile material that bridges the gap between craft studios and construction sites. Whether used for mounting prints, sculpting displays, prototyping, insulation, or signage, it delivers strength without bulk and clean surfaces that are easy to finish. This complete guide explores the many types of foam board, from paper-faced foam-core to PVC sheet and rigid insulation panels, and explains how to cut, join, bend, and finish them for professional results. With practical tips on adhesives, coatings, mounting strategies, and safety, it shows why foam board has become an essential choice for artists, builders, and designers alike.
What is Foam Rubber? History, Uses, and Modern Applications
Foam rubber—born from latex-foaming breakthroughs of the 1920s–40s—pairs a resilient polymer with a network of bubbles to cushion, insulate, and absorb sound. From early Dunlop and Talalay latex to today’s polyurethane and EVA variants, open- vs. closed-cell structure shapes feel, durability, and moisture behavior. This overview traces the history, demystifies how it’s made, and surveys modern applications across furniture, footwear, vehicles, medical supports, packaging, and acoustic panels.
What is Foam Made Of? The Science Behind the Bubbles
Foam is a lattice of gas bubbles in a polymer matrix, created by blowing agents and stabilized by surfactants. As the resin cures, additives and open- vs. closed-cell structure shape strength, insulation, and lifespan—linking chemistry to real-world performance.
What is Foam Insulation? Benefits, Types, and Costs
Foam insulation has transformed the way homes and buildings achieve comfort, efficiency, and durability. Unlike traditional insulation, foam not only slows heat transfer but also creates an effective air and moisture barrier, sealing gaps that cause drafts and energy loss. With options ranging from open-cell spray foam to rigid foam boards, homeowners can tailor insulation strategies to their specific climate and design needs. Costs vary depending on type and application, but the long-term energy savings and structural benefits often outweigh the initial investment. This comprehensive guide explores the benefits, types, installation methods, and costs of foam insulation, helping you make an informed choice for your home.
Understanding Foam: From Everyday Use to Industrial Applications
Foam is engineered air—cells inside a solid—that makes products lighter, safer, quieter, and more comfortable. This guide explains open- vs. closed-cell structures, key materials (PU, EPS, XPS, EVA, EPP), manufacturing methods, and the properties that matter, then tours real-world uses from packaging and construction to medicine and aerospace. You’ll also learn how to choose the right foam for your project and where sustainability is heading with recycling, bio-based options, and smarter design.
