Weathertex exterior cladding explained

Exterior cladding NZ

Are you wondering which cladding to use on your home’s exterior?

In this article, we share the type of cladding we use here at Manor Build and explain the benefits that set it apart. We also explain how to choose the right cladding for your home. 



How to choose exterior cladding


House cladding serves several vital functions, both practical and aesthetic. Below are some attributes to consider when evaluating house cladding options. 

1. Weather Resistance

The main purpose of cladding is to provide protection against harsh weather conditions such as rain, wind and UV radiation. It should prevent moisture from penetrating the structure and causing damage.

2. Durability

Cladding materials should be able to withstand long-term exposure to the elements without deteriorating, warping, or cracking. This reduces maintenance needs and increases the lifespan of the cladding.

3. Aesthetic Appeal

As a prominent feature of a building's exterior, cladding should enhance the visual appeal of the house. We recommend choosing a cladding material and style that complements the architecture and overall design. 

4. Low Maintenance

Opt for cladding materials that require minimal maintenance. Some materials may need periodic cleaning or painting, while others are virtually maintenance-free. 

5. Environmental Impact

Sustainable cladding materials, such as those made from recycled or renewable resources, can reduce the environmental footprint of the building.

6. Installation

Cladding that is easy to install can save time and money during the construction or renovation process.

7. Resistance to pests and decay

Some materials are more resistant to pests and fungi, helping to extend the lifespan of the cladding. 

8. Cost

Consider the initial cost of the cladding material, as well as potential long-term savings from reduced maintenance and energy efficiency. 

9. Compatibility 

The chosen cladding material should be compatible with the structural elements of the house and any insulation systems in place. 

10. Regulatory Compliance

All claddings in New Zealand have to comply with the building code. Make sure your chosen cladding meets these requirements. 



Weathertex cladding


Here at Manor Build, we use Weathertex cladding on all our prefab homes. This trusted brand is renowned for its sustainability, wide range of durable products, and affordability. Weathertex weatherboards are made from 97% hardwood and 3% paraffin wax, see below for the manufacturing process and the advantages these boards provide. 

The Weathertex manufacturing process

In the first step of the process, chipped Eucalypt hardwood is separated into base fibres. Most of the sugars and starches are removed and the coarse fibre is ground down. The refined fibre is then added to the board-forming machine, where excess water is drained away, producing a wet-lap. 

The wet-lap is trimmed and hot-pressed to remove further water and cook the fibres. This holds the board together, without the need for resins or toxic binders. When the boards are ready, a humidification machine restores their equilibrium moisture content of 8%. 

The boards are then planed to a nominal thickness of 9.5mm, cut into planks, moulded into shape, cured, and primed with a white acrylic primer.
