Astragal Bars Problems

When it comes to window designs, there’s a myriad of options that homeowners can choose from. Among the most popular and potentially confusing are the Georgian bars and the astragal bars. This article aims to shed light on their differences and address some common problems associated with them.

The Differences

1. Georgian Bars: These are inserts within the sealed unit of the window, giving the appearance of ‘Georgian’ windows. They are normally 18mm in width but can be as wide as 25mm or even rarer, 40mm. These bars are automatically incorporated within the sealed unit, providing an authentic look of Georgian windows.
2. Astragal Bars (Also known as Astrical Bars): These are placed on the OUTSIDE of the sealed unit. They are usually used over duplex layouts. A duplex layout means there are smaller layouts within the sealed unit that mimic individual sealed units, even though it’s just one single unit.

Problems with Astragal Bars

While astragal bars can certainly provide a touch of elegance and authenticity to windows, they aren’t without their fair share of challenges:

1. Cleaning Difficulties: With astragal bars, you have to clean each square as a separate pane of glass rather than cleaning a complete double-glazed unit. This means cleaning windows can become quite laborious, consuming a significant amount of time.
2. Handling by Window Cleaners: Given the structure of these bars, window cleaners must wipe and dry each individual square, which can be quite tedious. This often results in them rushing and being too aggressive, causing the bars to weaken or even fall off.
3. Durability Issues: Even though the bars are held at each end with clips, the center is typically unsupported. This means they can start to slip down once the sun softens the glue on the tape used to stick them on.
4. Heat Absorption: Certain colors, especially brown woodgrain/rosewood, can absorb more heat than white. This leads to the bars bowing down due to a lack of strength or reinforcing in the bars. Over time, exposure to the sun can cause these bars to deform.

Potential Solutions

1. Opt for Georgian Bars: These bars are placed within the window glazing unit, eliminating most of the aforementioned problems. They may cost more, but they provide a more genuine look and are easier to maintain.
2. Clear Windows: If you’re not set on having the bar aesthetic, consider opting for clear windows, especially if maintenance is a concern.
3. Consultation: Before deciding on which window design to choose, always consult with an installer. They can provide insights based on your home’s architecture, your maintenance preferences, and your budget.

In conclusion, while astragal bars can indeed offer an authentic, traditional look to your windows, it’s crucial to be aware of their challenges. Weigh the pros and cons before making a decision, and always prioritize long-term convenience and functionality over short-term aesthetics.
