The standard UK window apertures for new build houses can vary depending on several factors, including the specific requirements of the project, architectural design, and building regulations. However, there are commonly used window sizes and proportions in the UK construction industry. It's important to consult with architects, builders, or window manufacturers for precise measurements based on your project's needs and local regulations. That being said, here are some general guidelines:
- Window Apertures:
- For casement windows, the standard opening sizes for residential buildings are typically around 600mm to 1200mm in width and 900mm to 1800mm in height.
- Sash windows often have a narrower width and taller height, with standard sizes ranging from 600mm to 1200mm in width and 1200mm to 2400mm in height.
- Bay windows can vary significantly in size and design, but typical widths range from 1800mm to 3000mm, depending on the number of panes, with heights ranging from 1200mm to 2400mm.
- Sandstone Heads and Cills: The size of sandstone heads (lintels) and cills (sills) for windows will depend on various factors, including the window opening dimensions, the thickness of the sandstone, and the desired aesthetic appearance. Typically, the width of the sandstone head is determined by the width of the window opening, while the height is often proportional to the height of the opening.
As for the sandstone cill, it usually extends beyond the width of the window opening to provide a suitable ledge for water runoff and to protect the wall below the window. The width of the cill can vary based on personal preference and architectural design, but it typically ranges from around 100mm to 300mm.
It's essential to consult with a professional stone supplier, architect, or builder who can provide precise measurements and recommendations for the specific sandstone heads and cills required for your new build project. They can consider factors such as the load-bearing requirements, local building regulations, and the specific characteristics of the sandstone being used.
