Built from experience.

How we got here

Stewart and Cameron Scholten are brothers, licensed builders and Certified Passive House Tradespeople.

For years, Scholten Group worked much like any other residential building company in the Northern Rivers, building new homes, renovations and extensions around Ballina, Byron Bay and the surrounding region.

Over time, our attention shifted towards what makes a building perform well long after the builder has left site.

What makes a home truly comfortable, healthy and durable, and why do so many buildings struggle with air leakage, condensation and mould?

Those questions led us to Passive House, and changed the direction of the business.

The project that changed everything

Working with Sydney architect Kylie Mills and the wider project team, we built the first certified Passive House in the Northern Rivers at Ballina.

The home achieved an extraordinary 0.08 air changes per hour at 50 pascals (ACH50), one of the tightest airtightness results recorded in Australia.

Building to that level changed the way we thought about construction.

Every junction mattered. Every penetration mattered. Airtightness, insulation, moisture and ventilation all had to work together.

Pro Clima systems formed a major part of the building envelope, and spending months installing and detailing those products ourselves gave us an understanding you simply don’t get from a catalogue.

From building homes to helping others build better

That project made one thing clear:

Good products only work when people understand how to use them.

So Scholten Group began working more closely with Pro Clima, supporting builders, trades and merchants with the products, training and practical knowledge needed to get building-envelope details right.

Today, we supply Pro Clima systems across NSW and South East Queensland, run hands-on training and provide practical project support.

Pro Clima systems, technical support and training

Today, Scholten Group is a Pro Clima Partner with locations in the Northern Rivers and Brisbane.

We support the industry in three main ways.

Pro Clima systems

We supply Pro Clima membranes, tapes, sealants and building envelope systems through a growing network of hardware stores, timber merchants and building suppliers across NSW and South East Queensland.

Builders and trades can find product locally through our stockist network, while merchants have access to stock from our Northern Rivers and Brisbane locations.

Practical technical support

Because we have installed these systems ourselves, we understand the questions that arise when drawings meet the reality of a building site.

We help with product selection, system compatibility, installation questions and practical detailing, and can connect projects with Pro Clima’s specialist technical team where deeper technical input is required.

Training and education

We run practical training sessions for trades and merchant teams covering Pro Clima systems, airtightness, weathertightness, moisture management and installation.

For us, education is an important part of supplying the product. The better people understand why a system works, the better chance there is of getting the details right.

Local support, two locations

Scholten Group is based at Pearces Creek in the Northern Rivers, with a second location in Brisbane supporting South East Queensland.

Having people and stock on the ground in both regions means we can stay close to the projects, stores and people we support.
