How to Care for Timber Shutters in the Australian Climate

Introduction

Timber shutters are a classic window covering that add warmth and style to any home. In Australia’s sunny climate, timber shutters have practical benefits as well, providing insulation, UV protection, light control, and privacy. However, because of the extremes of heat, sunlight, and dryness that some parts of Australia experience, timber shutters require proper care and maintenance to keep them looking their best and functioning properly.

This article will provide guidance on caring for timber shutters specifically within the context of Australia’s climate conditions. We’ll look at how the climate impacts timbers and offer tips on cleaning, sealing, and protecting your shutters in each season across different regions of Australia. With the right maintenance strategy, your timber shutters can remain beautiful and functional for years to come.

Overview of Australia’s Climate

To understand how to best care for timber shutters, it’s helpful to first examine Australia’s climate conditions and how they may affect wood:

• High temperatures – Australia experiences periods of extreme heat, especially over the summer months. Sustained high temperatures can dry out and crack timber.
• Low rainfall – Much of Australia is arid or semi-arid, receiving lower rainfall than other parts of the world. Drier conditions remove moisture from wood.
• UV exposure – With a sunny climate and the hole in the ozone layer, Australia has high ultraviolet radiation levels. This can damage and discolor timber finishes.
• Coastal conditions – Homes along the coast are exposed to salty sea air and consistent onshore winds. The salt can erode and corrode timber over time.
• Seasonal variations – Different parts of Australia experience distinct wet and dry seasonal variations that impact timbers.

Understanding this context will help us tailor timber shutter care to counteract Australia’s climate risks. The next sections offer season-by-season maintenance tips for different regions.

Winter Care – Northern Australia

Homes across the tropical Top End and northern Queensland experience a dry winter season with very little rainfall. Dry season care considerations include:

Cleaning

• Dust buildup is common in the dry months. Clean shutters with a soft brush or damp cloth.
• Check for spider webs and insect nests around shutters. Vacuum or use gentle cleaning products to remove.

Moisture

• Mist shutters with water to keep the wood from drying out completely. Target areas that get less humidity.
• Place bowls or trays of water near shutters to add a bit of moisture to the air.

Sealing

• Inspect shutters and window frames for any cracks from seasonal contraction. Seal with appropriate caulk or filler.
• Add a fresh coat of paint or sealant if needed to protect the wood.

Sun protection

• Close shutters on sun-exposed windows during the hottest part of the day.
• Draw curtains over shutters to provide an extra UV buffer.

Follow these dry season care tips to prevent deterioration of your timber shutters in northern Australia.
