What Is The Difference Between Treated and Untreated Windows?

Explore the difference between treated and untreated windows. Learn how treatments improve durability, resist decay, and extend the lifespan of timber windows.

When choosing timber windows, you’ll often come across the terms treated and untreated wood. The difference lies in how the timber is prepared to enhance its durability, resistance to environmental factors, and overall performance. Understanding these differences is key to selecting the best option for your home or project.

At Dale Joinery, all our bespoke timber windows are made using sustainably sourced, treated European Redwood to ensure long-lasting quality and performance.

What Are Treated Windows?

Treated windows are made from timber that has undergone a process to improve its resistance to moisture, decay, and pests. This treatment involves applying preservatives or chemicals that penetrate the wood, protecting it against the elements and extending its lifespan.

Advantages of Treated Timber:

Enhanced Durability: Treated wood is less prone to rot and decay, even in high-moisture environments.

Increased Longevity: Timber treatments can extend the life of your windows to 60+ years with proper care.

Pest Resistance: Treatment protects against wood-boring insects and fungal growth.

Minimal Maintenance: Treated timber requires less upkeep, making it a practical choice for busy homeowners.

At Dale Joinery, our factory-applied three-coat paint finish adds an additional layer of protection, ensuring our windows stand the test of time.

What Are Untreated Windows?

Untreated windows are made from timber in its natural state, with no preservatives or chemical treatments applied. While untreated timber retains its natural beauty, it is more vulnerable to environmental damage and requires frequent maintenance.

Disadvantages of Untreated Timber:

Vulnerability to Decay: Exposure to moisture can lead to rot and degradation over time.

Susceptible to Pests: Untreated wood is at risk of infestation by insects like woodworms.

Frequent Maintenance: Regular sealing, staining, or painting is required to protect the wood from the elements.

Shorter Lifespan: Without treatment, the lifespan of the timber is significantly reduced, especially in harsh climates.

Why Choose Treated Timber Windows?

Treated windows offer better performance, durability, and peace of mind compared to untreated options. They are ideal for properties where long-lasting quality and reduced maintenance are a priority.
