Title: Spray Polyurethane Foam Insulation - PowerPoint PPT Presentation

Description: Spray polyurethane foam insulation (PUF) is a plastic-based insulator praised for its high resistance to heat flow, known as the R-value. It works wonders in stopping heat from passing through walls, roofs, and different parts of buildings. Made from two chemicals, polyol, and isocyanate, it forms a liquid foam that expands and solidifies when it meets air. By adjusting how much polyol and isocyanate are used, their thickness and density can be controlled. PUF is versatile in how it’s used: sprayed onto surfaces using a special sprayer, injected into walls for older buildings, or pre-made into panels for easy installation on walls or roofs – PowerPoint PPT presentation
