High-Performance Underlay for Monopitch Roof


Rory Kofoed from Pac Studio designed a magnificent home on Black Jack Road, Kuaotunu, which perfectly fits into the surrounding natural habitat of Otama Beach.


How was this project implemented?

The roof is a 30 m long monopitch design using the pro clima recommended method. The metal roof is installed over purlins mounted on a series of counter battens over the SOLITEX MENTO® 3000 Roof Weather Resistive Barrier which is supported by a ply sarking. This allows for sufficient ventilation between the roof and the roof underlay.

The inside of the framing, walls and ceiling is lined with INTELLO® PLUS, pro clima’s Intelligent Air Barrier, before GIB is installed. The INTELLO® PLUS layer ensures that internal moisture is not allowed to move through the structure and the insulation layer. This dedicated airtightness layer also increases the thermal performance of the home.

Use has also been made of beautiful Larch windows from Eco Windows to take advantage of the expansive sea views and the high R-value of 0.9. Designed with a subframe, these frames can also be installed separately of the windows. The glazing layer is designed to sit in the middle of the insulation value, which maximises the thermal performance. The windows are connected to INTELLO® PLUS using TESCON® PROFIL tape, which gives continuous airtightness and insulation layers.

The builder on the job, who is making sure it all goes to plan (pun intended), is Damien Percival and his team at Percival Construction. They have made light work of bringing this great design to life.

Congratulations to everyone involved! This design and build ensure that the home will be efficient and durable for many years to come.
