Insulation Guru Brisbane recently released a video that shines a spotlight on an important consideration when selecting insulation materials—how they respond to moisture. For homeowners, builders, and renovation experts, understanding the interplay between insulation and water exposure is crucial, especially in climates prone to dampness or specific areas of the home where moisture is a concern. This guide offers a deep dive into the characteristics of various insulation types, particularly focusing on earth wool, fibreglass, and polyester, providing necessary insights to make informed decisions.

The video begins with a vivid comparison, likening water-affected insulation to candy floss, which dramatically shrinks upon contact with moisture. This analogy sets the stage for a detailed examination of how certain insulation materials, specifically earth wool and fibreglass batts, behave when they become wet. Initially heavily compressed within their packaging, these materials can expand significantly when unpacked—a characteristic feature that unfortunately reverses in the presence of moisture, leading to substantial compression.

This inherent property highlights a significant limitation for earth wool and fibreglass insulation—they are not designed to endure wet conditions. Installed in environments meant to remain dry, such as attics or internal walls, these materials can suffer in performance if exposed to moisture, complicating their use in areas with any risk of water intrusion.

Conversely, the video introduces polyester insulation as a resilient alternative, capable of withstanding conditions that would compromise the integrity of more conventional materials. Polyester batts, characterised by their dense, non-compressible nature, maintain their thickness and insulative properties even when wet. This makes polyester an ideal choice for underfloor insulation, where occasional moisture exposure is possible, such as from mopping. The video reassures viewers that water passing through polyester insulation does not inflict permanent damage; instead, the material simply allows moisture to drip through and will dry out without losing effectiveness.

Insulation Guru Brisbane’s exploration of insulation responses to water is not just informative but also practical. By distinguishing the moisture resilience of polyester against the moisture vulnerability of earth wool and fibreglass, the video empowers viewers to make choices suited to their home’s specific needs. Whether prioritising durability in damp conditions or seeking the most cost-effective solution for dry areas, this guide underscores the importance of matching insulation material to environmental conditions.

For anyone involved in building, renovating, or upgrading their home insulation, this video serves as a crucial resource. It ensures that decisions are made with a comprehensive understanding of how different insulation types perform, guaranteeing long-term satisfaction and efficiency in insulation investments.
