Benefits of Using Structural Flooring & Underlay
Creates a Solid, Stable Subfloor: Provides a strong, even, and rigid base that prevents flexing and movement, ensuring the final floor covering performs correctly and lasts longer.
Superior Load Distribution: Effectively distributes point loads (e.g., furniture legs) across a wider area of the floor joists, enhancing the overall strength and safety of the floor system.
Improved Structural Integrity: When glued and screwed to the floor joists, it adds significant diaphragm strength to the entire building structure, improving its resistance to lateral forces like wind.
Minimises Squeaks and Noises: A secure installation with adhesives and fasteners prevents friction between the subfloor and joists, which is a primary cause of squeaky floors.
Barwon Timber supplies high-performance structural flooring underlay designed to deliver a stable, level, and durable base for timber, laminate, hybrid, and engineered flooring. Our underlay products enhance acoustic insulation, moisture resistance, and thermal efficiency, ensuring long-lasting comfort and performance in residential and commercial spaces.
