With over 15 years of experience in selling and servicing PVC windows, our company has encountered and resolved numerous issues and complaints related to various constructions. In this guide, we aim to provide impartial advice on what factors to consider when selecting PVC windows, free from brand or manufacturer bias.

When selecting windows, it's essential to prioritize your specific requirements. Before placing an order, it's crucial to clearly define the intended tasks and desired functionality of your future windows. In the following section, we will provide a brief overview of the components that make up modern PVC windows and explain how each component can impact the overall window performance.

Components of PVC Windows

PVC windows are composed of the following elements:

1. Frame: The fixed part of the window made from PVC profile.
2. Sash: The movable part of the window also made from PVC profile.
3. Metal reinforcement: A steel non-closed loop that provides structural strength to withstand external forces acting on the window.
4. Fittings: These include all locking and moving parts, which are installed on the opening sashes of the window, with some parts mounted on the window frame.
5. Glass unit: This encompasses various glass coverings used in the window, such as double or triple glazing, low-emissivity coatings, or other specialized glass treatments.

Specify the requirements and tasks for your future windows

Windows are commonly installed to enhance the thermal insulation properties of a room and retain heat within a building. However, in warm and sunny regions, the objective may be the opposite—to prevent the entry of solar heat and ultraviolet rays. There are also instances where these requirements can be combined within a single window. By ordering double-glazed windows with appropriate coatings, the cost of air conditioning and cooling on hot days can be significantly reduced. However, in domestic buildings or warm regions, there may not be a need to invest in windows with enhanced thermal insulation properties.

Additionally, it is important to determine the size of the window openings, as larger sizes necessitate the use of high-quality and reinforced hardware. When selecting windows, it is advisable to consider whether your house is located in an area prone to strong winds. Moreover, the floor level of the room should be taken into account, as it might require reinforced reinforcement for window installation. When glazing private houses or cottages, it is essential to consider the maximum and minimum permissible sizes of windows. Furthermore, the thermal expansion of PVC profiles should be considered, particularly when using laminated or colored profiles.

 

 

Changes in window design can have an impact on several components of the window. Let's explore each of these components in detail:

Frame and Material

The material used for the window frame, such as wood, aluminum, or PVC, can affect factors like insulation, durability, maintenance requirements, and aesthetics. Changing the design may involve using different materials or altering the frame structure, which can influence these factors.

Glazing

The type of glass and glazing used in windows can affect thermal insulation, soundproofing, and UV protection. Changes in window design may involve upgrading to double or triple glazing, adding low-emissivity (low-E) coatings, or incorporating gas fills between panes, all of which can enhance energy efficiency and comfort.

The double-glazed window is a crucial component of a window, occupying the largest area. Double-glazed windows consist of two or three panes of glass, offering enhanced thermal insulation properties.

In the past, the choice for windows was limited to two or three panes. However, advancements now allow for additional enhancements that significantly improve the thermal insulation capabilities of the window. One cost-effective method to enhance heat preservation is by installing double-glazed windows with a special energy-saving coating known as i-glass. This coating is applied to the inner surface of the double-glazed unit, ensuring its durability during operation.

The i-glass coating functions by reflecting the thermal spectrum inward, maximizing heat retention within the room. To identify windows with this coating, they are marked as 4i-10-4-4-10-4i. The number four represents the thickness of the glass panes, while ten indicates the distance between the panes. The letter "i" signifies the presence of the energy-saving coating. To optimize cost savings, it is advisable to install at least one internally coated glass pane.

By incorporating such enhancements, double-glazed windows can significantly improve the thermal insulation performance of a building, contributing to energy efficiency and creating a more comfortable indoor environment.

To enhance the thermal insulation properties of windows, double-glazed windows can be filled with argon gas instead of air between the panes. Argon, being a heavier gas, slows down molecular movement and reduces heat exchange between the interior and exterior of the house. For optimal performance, both chambers should be filled with argon. It is recommended to first install i-glass and then consider filling the chambers with argon. Such double-glazed windows are labeled as 4i-10Ar-4-10Ar-4i.

Furthermore, as an alternative to i-glass, Solar coated glass can be used as an additional layer on the outer pane. This coating not only retains heat inside the room but also reflects solar energy outward. As a result, on hot days, the room is less heated by the sun, enabling cost savings on air conditioning and cooling. Solar coated glass is commonly used in southern regions. In regions with cold winters and hot summers, a combination of solutions can be implemented by installing double-glazed windows with i-glass, argon gas filling, and Solar coating. These multifunctional double-glazed units are marked as 4i-10Ar-4-10Ar-4Sol.

Window Seals

The sealing around the window frame, including weatherstripping and gaskets, plays a crucial role in preventing air and water leakage. Modifying the window design may require improving the quality of seals or adopting different sealing techniques to enhance insulation and prevent drafts or moisture intrusion.

Hardware and Operation

The hardware components of a window, such as locks, handles, hinges, and opening mechanisms, can impact functionality, security, and ease of use. Changes in design might involve upgrading to more advanced or secure hardware, altering the opening style (e.g., casement, sliding, tilt and turn), or introducing automation and smart features.

To ensure long-lasting performance of windows, it is advisable to opt for well-established brands with a proven track record in the market. This way, if any hardware component fails, it will be easier to find and replace if needed. Choosing lesser-known hardware brands that have limited compatibility with manufacturers can make it challenging to find the right replacement parts in case of a breakdown. In such situations, there is a possibility of having to replace the entire window hardware, which can be expensive and labor-intensive.

Additionally, when selecting windows for a private home, it may be worthwhile to consider anti-breaking hardware, despite the slightly higher cost. This type of hardware is reinforced and features special locking mechanisms and mating strips. While it cannot completely eliminate the risk of burglary, it significantly complicates potential break-in attempts and enhances security measures for the window.

Size and Configuration

The size and configuration of windows influence the amount of natural light, ventilation, and views in a space. Changes in design may involve resizing or reconfiguring windows to optimize these aspects, taking into account architectural considerations, building codes, and structural requirements.

Aesthetics and Style

Window design significantly contributes to the overall aesthetics and style of a building. Alterations in design can involve changing the window shape, adding decorative elements, selecting different grille patterns, or matching the window design to the architectural style of the building.

Energy Efficiency and Sustainability

Changes in window design can impact the energy efficiency and sustainability of a building. Upgrading to more energy-efficient windows, such as those meeting ENERGY STAR standards, or incorporating renewable materials can enhance the building's overall energy performance and reduce its carbon footprint.
    

Maintenance and Cleaning

Window design can influence the ease of maintenance and cleaning. Modifying the design may involve adding features like easy-to-clean coatings, removable grilles, or accessible hardware to simplify upkeep and ensure longevity.

 

The market for unplasticized polyvinyl chloride (uPVC) windows continues to demonstrate impressive growth, and it is expected that this trend will persist in the future. Source.
