Fletcher Insulation Products for Walls, Ceilings & Roofs

Fletcher Insulation's range covers every part of a build. Pink Batts delivers trusted thermal and acoustic performance for ceilings and walls across R1.5 to R7.0. FirmaSoft Wall and Ceiling insulation batts are made to Fletcher's proprietary low-dust formula, using up to 80% recycled content, and are perfectly balanced — soft and comfortable to handle, with a firm fit for easy installation. Soundbreak targets dedicated acoustic performance between rooms, while Sisalation and Permastop handle roof and wall wrap applications, protecting the building envelope during and after construction. Pink Partition and supaBATT round out the range for partition walls and commercial-grade applications.

Fletcher Protect — Stonewool Party Wall Batts

For fire-rated separating walls in NCC Class 1 multi-residential buildings, Fletcher Protect brings stonewool insulation into the range, purpose-built where compress-filling with mineral wool is required.

Sealing & Accessories

A correctly installed Fletcher system relies on proper sealing at every join. The range includes Thermatape thermal break tape, Vapastop 883 foil tape, and dedicated seaming tape, all designed to maintain an airtight, continuous barrier across wall, roof and wrap installations.

From Sisalkraft to Pink Batts — The Fletcher Story

Fletcher Insulation's history in Australia stretches back to Australian Sisalkraft in the 1930s, through ACI Australia's glasswool batt manufacturing in the 1950s, the Owens Corning trademark era, and the iconic Pink Panther campaign that made Pink Batts a household name from the 1970s onward. Today, Fletcher Insulation stands as a leading Australian manufacturer, distributor and technical support provider for the building construction industry, continuing that legacy across the full Pink Batts, FirmaSoft, Sisalation, Permastop and Fletcher Protect range.
