Installation Costs
Factors Influencing the Price of uPVC flush casement windows.
Size and Dimensions
 Larger windows will naturally cost more due to the additional materials and labor involved.
Glazing Options
Double glazing is the most common choice for uPVC flush casement windows, offering excellent energy efficiency and sound insulation. However, if you’re looking for superior insulation and noise reduction, triple glazing is an option worth considering.
It’s important to note that while triple glazing can improve energy efficiency, it tends to be more expensive than double glazing.
Key Points to Consider:
Secondary Glazing: Offers basic insulation and soundproofing, typically cheaper than double and triple glazing but less efficient.
Double Glazing: The most popular option, balancing affordability and energy efficiency, perfect for most homeowners.
Triple Glazing: The most efficient glazing option, providing superior insulation and soundproofing, ideal for properties in noisy areas or those looking to maximise energy savings.

| Glazing Type | Small (600mm x 900mm) | Medium (900mm x 1200mm) | Large (1200mm x 1500mm) | Extra Large (1500mm x 1800mm) |
