Windows and doors, especially French doors, are frequently the source of leaks and other issues in homes today. Many problems stem from poor design and the use of incorrect materials. It’s surprising how seemingly small design flaws can cause major headaches down the line.

The Minimalist Design Problem

A frequent issue, particularly with modern minimalist designs, is that windows and French doors are often not designed to be weatherproof. In areas exposed to strong winds or horizontal rain, this can lead to significant problems. Hilly areas, in particular, are prone to weather exposure, which can highlight design weaknesses in many homes.

Lessons From The Past

For generations, windows and doors have been developed, and over time, builders learned through experience how to construct them effectively. However, modern construction seems to have lost some of these crucial lessons, either by thinking they know better or simply not realizing the issues. It appears that the pursuit of minimalist design has led to the elimination of features that have historically ensured doors and windows function correctly.

Common Design Problems With French Doors

Here are some common design flaws to be aware of:

• Lack of Weatherproofing at the Bottom: Rain driven by wind often gets under French doors, and this can be difficult to remedy. Some use weather strips as a temporary fix, but this can cause issues such as floor marks, difficulty opening the door, and inadequate sealing. Good design involves a step between interior and exterior floor levels, a threshold, or bottom tracks that seal and drain effectively.
• Vertical Edge Weatherproofing Issues: Similar to the bottom of doors, the vertical edges can also be a source of leaks. Solutions include a step in the leading edge of the door or a weather strip on the outer surface of one door. A well-designed door will have a groove in one door and a vertical strip on the other to create a “labyrinth” seal.
• Non-Replaceable Glass Panes: Many doors are built with the glass fixed in such a way that it can’t be replaced without taking the door apart. Traditional methods such as using linseed oil putty or wooden beading allow for easier glass replacement.
• Horizontal Surfaces Under Glass Panes: When the wooden frame under glass is horizontal, rain can sit against the glass and seep through, particularly when there’s no sealant. This can be easily avoided by slightly beveling the lower surface of the wood and ensuring proper sealant is used.
• Poorly Sealed Glass Panes: Many builders don’t use enough sealant when installing glass in door and window frames. Tapping the glass will show if there is insufficient sealant, with rattling being an indicator. Acid-free silicone sealant is recommended for this purpose.
• Use of Bingkirai Wood: Although a good wood, bingkirai expands when wet and contracts when it dries out, potentially causing structural issues including cracking walls.
• Insufficient or Low-Quality Hangings: French doors, especially folding ones, need strong hinges and tracks. Low-cost fittings tend to rust quickly and may not be strong enough for the weight of the doors.
• Poorly Functioning Locks: Misaligned doors, poorly placed locks, or the use of low-quality locks can all cause difficulty in locking French doors.
• Warped Doors and Windows: Using wood that is not fully seasoned will often result in warping, which makes it difficult to close doors properly. Proper seasoning of the wood before construction is essential. Kiln drying can speed up this process if needed.

Modern Construction Problems

Problems like handles hitting the frames, track stops not properly set, and doors that don’t provide sufficient security are frequently encountered. It is important to choose a builder who pays attention to these details.

Conclusion

By understanding these common problems, you can make more informed decisions when it comes to designing and building your home.
