A review of E3/AS1 changes and an alternative flooring solution in NZ

Are you aware of the big upcoming changes to the building code here in New Zealand? Our team here at Archant has been watching the developments closely.

On November 5th, 2022, a major shift will go into effect regarding timber-based flooring products. It’s all about reducing and eliminating internal flooring moisture for health and safety. In the past, timber-based products were considered an “acceptable solution Under the newly revised E3/AS1 guidelines, however, you will now need to file for an “alternative solution” to satisfy the Building Consents Authority.

This requirement applies specifically to any rooms that include water sources such as kitchens, bathrooms, and laundries. The way it’s written offers further clarity by specifying that any “areas that have sanitary fixtures” are part of the new code. Essentially any space within 1.5 meters of potential water splash is affected by the change.

What Does E3/AS1 Internal Moisture Building Code Change?

We understand that’s a lot of industry jargon to interpret so allow us to unpack this in layman’s terms. Timber is no longer an “approved solution” for flooring in wet areas. You can still use timber products for your choice of flooring material, but special permission is required to do so. For residential kitchens, bathrooms, and laundries, you’ll now need to submit documentation of an “alternative solution”.

Applying for this offers an apparent way around the new rule, but is that a risk you’re willing to take? Despite how gorgeous a hardwood floor can be, they’re problematic when used near moisture. This new code forces designers and homeowners alike to rethink their choice of flooring.

Why the Update?

Problems with moisture, mould and mildew can be a real safety hazard. In section E3.3.3 of the building code, it states that “floor surfaces of any space containing sanitary fixtures or sanitary appliances must be impervious and easily cleaned”. Timber was simply falling short in this regard. This new change will align those requirements more consistently. It applies to all types of timber flooring products and does not stipulate any variances for the type of finish used on the floor regardless of lacquer, wax, varnish, etc.

Flooring for the Future

Since timber is no longer classified as an “acceptable solution” when used in these wet areas, you may want to find a preferable material for your flooring needs. We know these new guidelines may be disappointing to some. Yet, one of our philosophies at Archant is to find solutions that remove friction from the design process.
