How to choose the right sub flooring with KeyFloor

Across the country, New Zealand’s new rules for building granny flats – which allow a new standalone dwelling of up to 70sqm without resource consent or building consent (conditions apply; contact your local council), are bringing forward dreams of a backyard rental or a cute cottage for nana. Start your construction plan with quality sub flooring materials; KeyFloor fine oriented strand board (FOSB) flooring panels, used in offices, schools and housing developments, deliver next-level strength and a sleek finish for a top-notch D.I.Y. build.

Tip: Always wear the appropriate safety equipment (safety glasses, gloves, ear muffs and a mask, for example) and always follow the instructions for the product or equipment.

What's the difference between KeyFloor FSOB and standard OSB?

The difference between KeyFloor FOSB and standard OSB is clear at a glance – and a touch. A dense core is overlaid with twin layers of fine hardwood fibres, delivering a flawless surface, while the tongue-and-groove system ensures the panels sit snugly together for a flat, clean finish that’s flooring-installation-ready and ideal for underlay, membranes and finishing. 

How is KeyFloor built for our environment?

The Kiwi climate is fierce, so our building materials need to be made of stern stuff, and KeyFloor meets the brief:

• Beneath the smooth surface is a high-density engineered core.
• It’s created with tightly aligned hardwood strands and moisture-resistant resins, which resists movement, swelling and edge damage.
• Not only is KeyFloor a robust, long-lasting subfloor solution once laid, it’s also tougher than your average OSB on the building site – KeyFloor is designed to withstand up to 12 weeks of weather exposure, giving you much-needed flexibility in case of construction delays.

How does KeyFloor's easy install work?

With advancements in digital printing technology, it's now possible to get the look of timber floors in wet areas without the associated issues. Timber-look porcelain floor tiles replicate the look and natural variation of real wood, yet are incredibly low maintenance and water resistant, perfect for bathrooms and shower zones. You can also use them with underfloor heating. 

How can you tell if KeyFloor meets the right building codes?

Underneath the silky surface, KeyFloor panels are products you can trust. They’re manufactured to meet or exceed all New Zealand building codes, including NZBC B2 durability (50 years structural, 15 years non-structural) and formaldehyde emission class E0.
