Considerations for Selection

When selecting wall insulation, consider factors like thermal performance (U-values), fire resistance, acoustic properties, and environmental impact. The choice will depend on your specific application, be it residential, commercial, or industrial.

Remember, proper installation is key to maximising the benefits of insulation. Consult with professionals to ensure the best fit for your project.
