Discover what affects the price of double glazing from window types to installation charges. This guide helps you balance budget and aesthetics for your project.
The Type of Windows You Choose
The type of windows you select has a major impact on the price of double glazing. Standard casement windows are typically the most cost-effective, while more complex designs, such as sash or tilt-and-turn windows, tend to be more expensive due to their intricate mechanisms. Bay and bow windows also increase costs as they require more materials and structural support.
Additionally, bespoke or custom-made windows will cost more than off-the-shelf options, as they are tailored to specific dimensions or styles. The choice between fixed and opening windows also affects the price, as operable windows require additional hardware and sealing. Selecting the right type depends on both your budget and the overall aesthetic you want to achieve.
The Size and Number of Windows
Larger windows require more materials, increasing the cost of both the glass and frames. A home with multiple windows will naturally have higher costs compared to a property with fewer openings. If you are replacing all your windows at once, some companies may offer discounts for bulk installations.
However, homes with irregularly shaped or oversized windows may face additional charges for custom manufacturing. The positioning of the windows can also impact costs, as those in hard-to-reach areas may require specialist installation techniques.
When planning your budget, it is important to balance the number and size of windows with your overall financial constraints while ensuring they meet your property’s needs.
Frame Materials: uPVC, Aluminium or Timber?
The choice of frame material plays a key role in determining the cost of double glazing. uPVC is generally the most affordable option, offering durability and energy efficiency with minimal maintenance. Aluminium frames are more expensive but provide a sleek, modern appearance with enhanced strength, making them ideal for larger windows.
Timber frames tend to be the most expensive due to the cost of natural materials and the maintenance required to protect them from weathering. However, they offer a traditional aesthetic that suits period properties. The lifespan and energy efficiency of each material should also be considered, as higher upfront costs may result in long-term savings through improved insulation and durability.
Glass Options and Energy Efficiency Ratings
The type of glass used in double glazing significantly affects the overall cost. Standard float glass is the most basic option, while low-emissivity (Low-E) glass enhances thermal insulation, making it more expensive. Triple glazing is another premium option that improves energy efficiency and noise reduction but adds to the cost.
The energy efficiency rating of the glass also plays a role, with A-rated or A+ rated glazing offering the best insulation but at a higher price. Additional features such as laminated or toughened glass for security purposes, or self-cleaning glass, can further increase costs.
Choosing the right glazing specification depends on your priorities for insulation, noise reduction, and security.
Installation Costs and Labour Charges
The cost of installing double glazing varies depending on the complexity of the job and the company you choose. Labour charges can be higher for properties requiring structural alterations, such as enlarging window openings or reinforcing frames. Installation costs may also increase if scaffolding is required for upper-floor windows.
Some companies include labour in their pricing, while others charge separately, so it is important to obtain a detailed quote. Additionally, removing and disposing of old windows can add to the overall expense. Choosing a reputable installer ensures the job is done to a high standard, preventing future issues such as poor sealing or draughts.
