Frequently Asked Questions
Does glasswool insulation shrink?
Glasswool insulation is designed to be stable and durable, but performance depends on installation quality. Gaps, compression, or poor fitting can reduce effectiveness, even though the material’s declared R-value remains stable.
What is the R value of glasswool insulation?
Glasswool is available in a wide range of R-values depending on thickness and product type. In New Zealand, R-values are declared to AS/NZS 4859.1 and listed on product packaging or datasheets. Compliance targets are set by Building Code H1, such as R6.6 for roofs.
