R1.5 Wall insulation is the right fit for tight spaces and steel frames. Shop Fletcher's Pink Batts R1.5 wall insulation at Melbourne Insulation Online - Melbourne's local insulation experts — and get reliable thermal performance where thicker batts simply won't fit!

Not every wall cavity is created equal. For steel-framed construction, narrow stud profiles, and retrofit situations where space is at a premium, R1.5 Pink Batts deliver practical, compliant insulation in a slim, easy-to-handle format that fits where other products can't.

Why R1.5 for Walls? R1.5 wall batts are a specialist product designed for applications where wall cavity depth is limited or where a thermal break layer is required alongside other insulation systems. They're commonly specified for:

• Steel stud framing - where batt compression must be avoided to maintain rated R-value performance
• Narrow wall cavities - in older Melbourne homes and heritage renovations where standard 90mm batts won't fit
• Secondary insulation layers - used in conjunction with higher R-value batts to boost overall insulation
• Commercial and light industrial fitouts - where lightweight, low-profile insulation is required between internal partition walls

While R1.5 sits at the entry level of the wall insulation range, it plays an important role in composite insulation systems and are often paired with external cladding insulation, reflective foil wraps, and higher R-value ceiling insulation to achieve overall NCC compliance and NatHERS energy ratings.

Who is R1.5 Wall Insulation For? R1.5 Pink Batts are the right call for:

• Steel-framed residential and commercial builds where narrow cavity depth limits thicker batt use
• Heritage and period home renovations across inner Melbourne where original wall profiles are narrow and non-standard
• Commercial fitouts and office partitions requiring lightweight insulation between internal stud walls
• Acoustic partition walls in apartments, townhouses, and multi-residential buildings
• Composite wall insulation systems where R1.5 forms part of a layered insulation solution alongside foil wraps or other bulk insualtion (for example cross layering of batts)
• Renovation and retrofit projects where full wall cavity access is restricted

Please note R1.5 alone won't meet NCC minimum wall insulation requirements as a standalone solution - but it's a highly effective component in a layered insulation system.
