FAQ About Internal Wall Insulation
Can internal wall insulation help reduce noise between rooms?
Yes. Acoustic insulation batts are specifically designed to minimise sound transfer between internal walls, especially effective in bedrooms, media rooms, or multi-family residences.
Do I need insulation in every internal wall of the house?
Not necessarily. Most homeowners insulate between living areas and bedrooms or bathrooms to improve privacy and thermal zoning.
What R-value is best for internal wall insulation in Melbourne homes?
An R2.0–R2.7 is common for internal applications, but it depends on your project’s acoustic or thermal goals. Our team can advise based on use case.
How is internal wall insulation different from external wall insulation?
Internal insulation focuses more on noise reduction and maintaining internal room temperatures, while external insulation protects against outdoor temperatures.
Is internal wall insulation safe to use around wiring and plumbing?
Yes, but it must be installed correctly. Always use products that comply with AS/NZS standards and consult your installer or electrician for guidance.
Can I install internal wall insulation myself?
DIY installation is possible for batts, but for best acoustic and thermal performance, we recommend working with a professional installer.
What building codes apply to internal wall insulation in Australia?
Insulation products must comply with the NCC and relevant AS/NZS standards. We supply code-compliant solutions for residential and commercial applications.
How does insulation affect room temperature in winter and summer?
It slows heat flow, keeping warmth in during winter and blocking heat during summer — making your home more comfortable and reducing reliance on air conditioning.
Are your products fire-rated?
Yes, many of our insulation materials come with fire resistance ratings. Contact us to check compliance for specific applications.
