What to look out for when buying a round window

Round wooden windows can bring elegance and charm to any home. However, purchasing one requires careful consideration of quality, durability, and craftsmanship. Below is a comprehensive guide on what to look for when buying a round wooden window.

1. Avoid Biscuit Joints in Frames

Biscuit joints, often used to joint picture frames, are not ideal for round wooden window frames. Biscuit joints, while quick to assemble, aren’t strong enough to withstand the stresses that windows endure over time, especially in a rounded design. Biscuit joints may loosen or weaken under pressure or temperature changes, potentially leading to separation of frame segments. In a round window the biscuit joint is suitable for reinforcing the beading, as the beading is secured to the frame with screws or glue, but to use a biscuit joint as the main strength point for a large round frame is highly risky.

Instead, look for frames joined through lamination. This is where two or more circles are laminated together, giving incredible strength and resistance to twisting. This method creates a tighter, longer-lasting connection, ensuring the frame maintains its shape and integrity even after years of use.

2. Check Wood Quality

• Type of Wood: High-quality hardwoods like Sapele, Oak, or Chestnut are highly durable and offer natural resistance to moisture and pests. Ensure the wood type is appropriate for your climate and fits the aesthetic of your home. Alternatively, quality Nordic Pine can be used when treated well for termites and mold.
• Treatment and Finish: Proper treatment and sealing are essential to prevent rot, warping, and fading. Look for UV-resistant finishes and protective coatings that will guard against weather and wear.

3. Inspect Craftsmanship and Joinery

• Precise Joinery: Since a round shape is challenging to produce accurately, ensure the joinery is precise. Tight joints prevent drafts and contribute to energy efficiency.
• Smooth Curves: Look for a consistent curve without gaps or irregularities, as these indicate skilled craftsmanship and ensure a more seamless fit.

4. Evaluate Glass Quality and Glazing Options

• Energy Efficiency: Double or triple glazing helps regulate indoor temperature, reducing energy costs. Consider Low-E glass, which provides additional energy savings by reflecting heat back into the room in winter and keeping it out in summer.
• UV Protection: Windows that filter UV rays help prevent furniture and flooring from fading.
• Safety Glass: Tempered or laminated glass is more resistant to impact and shatters into small, less dangerous pieces if broken, which is especially useful in family homes.

5. Examine Insulation and Weatherproofing

• Weatherstripping: High-quality weatherstripping seals gaps around the frame to prevent air leaks and water infiltration, keeping your home comfortable and dry. This is especially crucial for round windows, as their shape requires careful fitting.
• Thermal Performance: Choose windows that meet or exceed energy efficiency standards, as this will help lower heating and cooling costs. A well-insulated window is a long-term investment in your home’s efficiency.

6. Assess Hardware and Opening Mechanism

• Durable Hardware: For operable windows, choose corrosion-resistant hinges and handles, particularly if you live in a coastal area.
• Smooth Functionality: Check that the window opens and closes smoothly. High-quality hardware and proper weight distribution ensure ease of use, which is particularly important for heavier wooden windows.

7. Professional Installation

• Precise Fit: Round windows require precise installation to avoid air leaks, water infiltration, and frame misalignment. An experienced installer will ensure a snug, secure fit, which is vital for the window’s performance and longevity.
• Alignment: Even minor misalignments can compromise the window’s functionality. Proper alignment also supports energy efficiency by minimizing air gaps.

8. Consider the Design and Aesthetic

• Frame Style and Finish: Choose a style that complements your home. Round windows can be striking design elements, so consider finishes and frame thicknesses that will enhance your space.
• Customization: Look for options for finish and size, allowing you to create a window tailored to your taste and needs. A high quality window manufacturer should be able to offer these options.

In Summary

A round wooden window can be a beautiful addition to any home, but the choice requires close attention to detail. By asking for laminated joinery (and steering clear of frames held together by biscuit joints), high-quality wood, glazing options, and careful installation, you can be sure your window will be as durable as it is attractive. Make these considerations, and your round wooden window will enhance your home for many years to come.
