Frequently Asked Questions

Unlike standard casement windows that protrude from the frame, flush sash windows sit completely flush within the frame, creating a seamless, traditional appearance. This design replicates the look of historic timber sash windows while incorporating modern uPVC performance benefits.

Absolutely. Their authentic design makes them an excellent choice for period properties, listed buildings, and conservation areas where maintaining architectural integrity is crucial. The traditional appearance combined with woodgrain finish options often meets planning requirements where standard uPVC windows might not be permitted.

Extremely energy efficient. Our flush sash windows typically achieve A-rated energy performance with U-values as low as 0.8 W/m²K when using triple glazing. This represents a significant improvement over original timber sash windows and exceeds the performance of many modern standard windows, reducing heating costs and environmental impact.

Very little maintenance is required. Unlike timber windows that need regular painting and treatment, our uPVC flush sash windows simply need occasional cleaning with mild soapy water to maintain their appearance. The durable materials are resistant to rotting, warping, and fading, ensuring they look beautiful for decades with minimal effort.

The installation timeline depends on the number and complexity of windows being replaced. Typically, our professional installation teams can complete a standard single window replacement in 2-3 hours. For a full property with 10-15 windows, we usually complete the work within 2-3 days, ensuring minimal disruption to your household. We provide a detailed timeline during your free consultation.
