In the quest for energy efficiency, comfort, and aesthetic appeal, double glazed windows have become a staple in modern homes. However, like any other component of a building, double glazed units have a lifespan and will eventually require replacement. This article offers an extensive and informative look at replacement double glazed units, exploring their benefits, the signs that indicate a need for replacement, the replacement process, and factors to consider when choosing new units.
Understanding Double Glazed Units
Double glazed units, also referred to as insulated glass units (IGUs), consist of two panes of glass separated by a spacer bar and sealed around the edges. The space between the panes is typically filled with air or an inert gas like argon, which acts as an insulator, reducing heat transfer. This construction significantly improves the thermal performance of windows compared to single glazed ones, leading to reduced energy bills and enhanced comfort.
The Benefits of Replacement Double Glazed Units
Over time, the seals of double glazed units can deteriorate, allowing moisture to enter the space between the panes. This results in condensation build-up, fogging, and reduced visibility. In such cases, replacement double glazed units are necessary to restore the window’s functionality and aesthetic appeal. New units offer several benefits, including:
- Improved energy efficiency: Advances in technology have led to the development of high-performance double glazed units with enhanced insulation properties. Replacing old units with newer ones can significantly reduce heat loss, leading to lower energy bills and a smaller carbon footprint.
- Enhanced comfort: By minimizing heat transfer, replacement double glazed units help maintain a comfortable indoor temperature throughout the year. They reduce drafts, cold spots, and condensation, creating a more pleasant living environment.
- Noise reduction: The insulating properties of double glazed units also extend to soundproofing. Replacing old units can significantly reduce noise pollution from outside, creating a quieter and more peaceful home.
- Increased security: Modern double glazed units often incorporate toughened or laminated glass, which is more resistant to breakage and forced entry. Replacing old units can improve the security of your home and deter potential intruders.
- Enhanced aesthetics: New double glazed units can revitalize the appearance of your windows and enhance the overall aesthetic appeal of your home.
Signs That You Need Replacement Double Glazed Units
Several telltale signs indicate that your double glazed units may be nearing the end of their lifespan and require replacement. These include:
- Condensation between the panes: This is a clear sign that the seal of the double glazed unit has failed, allowing moisture to seep in. Condensation can obstruct visibility and create an unsightly appearance.
- Fogging or misting: Similar to condensation, fogging or misting between the panes indicates a broken seal and the need for replacement.
- Drafts and cold spots: If you feel drafts or cold spots near your windows, it could be a sign that the insulation properties of the double glazed units have deteriorated.
- Difficulty opening or closing windows: Warped or damaged frames can also affect the functionality of double glazed units, making it difficult to open or close windows smoothly.
- Visible damage: Cracks, chips, or other visible damage to the glass or frame also warrant replacement.
The Replacement Process
Replacing double glazed units is a task best left to professionals. While it is possible to replace the units yourself, it requires specialized tools and knowledge to ensure a proper fit and seal. Hiring a reputable window company or glazier will guarantee a professional installation and minimize the risk of future problems.
The replacement process typically involves the following steps:
- Measurement and ordering: A professional will carefully measure your existing windows to ensure the new double glazed units fit perfectly. They will also discuss your requirements and help you choose the right type of glass and spacer bar for your needs.
- Removal of old units: The old double glazed units will be carefully removed from the window frames. Any damaged or deteriorated sealant will be cleaned and prepared for the new units.
- Installation of new units: The new double glazed units will be fitted into the window frames and secured with new sealant. The installer will ensure a proper fit and airtight seal to prevent future problems.
- Finishing touches: Any final adjustments or cleaning will be performed to ensure the windows operate smoothly and look their best.
Factors to Consider When Choosing Replacement Double Glazed Units
When selecting replacement double glazed units, several factors should be taken into consideration:
- Energy efficiency: Look for units with a low U-value, which indicates good insulation properties. Consider units filled with argon or krypton gas for enhanced thermal performance.
- Glass type: Choose the right type of glass for your needs. Options include clear glass, tinted glass, low-emissivity (low-E) glass, and self-cleaning glass.
- Spacer bar: The spacer bar separates the two panes of glass and plays a crucial role in the unit’s insulation. Choose a spacer bar made from a durable and thermally efficient material, such as warm-edge spacer bars.
- Frame material: Ensure the new double glazed units are compatible with your existing window frames. If you’re also replacing the frames, consider materials like uPVC, timber, or aluminum, each with its own advantages and disadvantages.
- Cost: Replacement double glazed units come in a range of prices depending on the size, type of glass, and other features. While it’s important to consider your budget, prioritize quality and energy efficiency for long-term savings.
- Warranty: Choose a reputable supplier that offers a comprehensive warranty on both the units and the installation.
Conclusion
Replacement double glazed units offer a cost-effective and efficient way to revitalize your windows, improve energy efficiency, enhance comfort, and increase the value of your home. By recognizing the signs of deterioration and choosing the right replacement units, you can enjoy the benefits of double glazing for many years to come. Always seek professional assistance for the replacement process to ensure a seamless and successful installation.
