Pressure-Treated vs. Dip-Treated Garden Sheds: Which is Best?
When choosing a garden shed the type of timber treatment is a crucial factor that affects longevity, maintenance, and overall durability. The two main options are Pressure-Treated and Dip-Treated timber. Understanding the differences will help you make an informed decision when purchasing a garden shed.
What is Pressure-Treated Timber?
Pressure-treated timber undergoes a deep preservation process where wood is placed in a vacuum chamber and infused with protective chemicals. This treatment ensures the preservatives penetrate deep into the wood fibres, providing long-lasting protection against rot, fungi, and insect attacks.
Key Benefits of Pressure-Treated Timber on a Garden Shed:
- Long-lasting protection – Durable and long-lasting. A life expectancy of 15+ years should be achievable.
- Low maintenance – Although it is still recommended to annually treat your Pressure-Treated garden shed with a high-quality wood preserver, this is less important compared to a Dip-Treated garden sheds.
- Resistant to rot, decay and insect attack – Pressure-Treated timber offers excellent protection against rot, decay and insect damage (such as woodworm) to prolong the life of your garden shed.
- All Weather Protection – Pressure-Treated timber is suitable for exposure to all weather conditions. Ideal for the British weather!
- Appearance – Pressure-Treated timber typically has a more natural appearance. It is also easier to over-paint to the colour of your choice should you wish.
What is Dip-Treated Timber?
Dip-treated timber is when the timber is submerged into a preservative solution for a short period of time, allowing the preserver to be absorbed into the timber. While this method provides a degree of protection to the timber (and is better than no protection at all), it does not give sufficient time for the protective treatment to penetrate deep into the timber and provide a long-lasting protection barrier. This will require a higher degree of maintenance to your garden shed once installed (at least an annual maintenance treatment).
Key Benefits of Dip-Treated Timber:
- More affordable – Dip-Treated Garden Sheds typically cost less than a pressure-treated equivalent.
