Double glazing, also known as insulated glazing, refers to windows made up of two panes of glass with a gap between them that is filled with air or gas. This seemingly simple upgrade offers immense benefits for your home, from better energy efficiency to noise reduction, security enhancements, and more.
Suppose you are considering installing double glazed windows. In that case, this comprehensive guide covers everything you need to know, from understanding the advantages to choosing the right type and installer for your needs. Read on to learn why double glazing could be one of the best investments for your home.
What is Double Glazing?
As the name suggests, double glazing consists of two parallel panes of glass sealed inside a window frame, with a gap between them filled with air or gas. This contrasts single-glazed windows, which have only one sheet of glass.
The air space creates an insulating barrier between the inside and outside of your home. It prevents warm air from escaping during winters and stops cold air from entering. In summer, it keeps your interiors cooler by blocking heat gain. Additionally, using argon or other inert gases between the glass panes enhances insulation even further.
While double glazing units can be fitted into existing window frames, replacing old single glazed windows with entirely new double glazing yields optimal results. Modern double glazed windows feature technologically advanced glass, frames, and sealing that maximize efficiency.
Benefits of Double Glazing
The advantages of double glazing installation in Adelaide go beyond aesthetics, offering tangible benefits for your home and your well-being. Here are some key reasons to consider this upgrade:
Improved Energy Efficiency
Double glazed windows can substantially reduce home heating and cooling costs by providing better insulation, heat retention, and preventing drafts. You can achieve savings of 25-50% on annual energy bills after installation. During extreme weather, the effects are even more pronounced. Ultimately, this translates into higher comfort and lower environmental impact.
Reduced Noise Pollution
The air-tight seal and a layered glass structure result in effective soundproofing from outdoor nuisances like traffic noise. Indoors, it also contains sounds within a room. This allows you to sleep, work, or relax without distraction. Noise reduction is upwards of 50% compared to single-pane windows.
Enhanced Security
Getting through is extremely difficult with double glazed windows that feature laminated or tempered glass. Adding multi-point locks and hardware further deters any unwanted access. This provides peace of mind and reliability for homeowners.
Reduced Condensation
Since insulated glazing minimizes cold spots near window panes, it mitigates interior condensation, mold and mildew issues prevalent with single glazing. Keeping your home free of dampness has health advantages as well.
Increased Property Value
Investing in double glazing adds tangible, marketable value to any home. Not only does it drastically improve aesthetics, functionality, and comfort, but buyers recognize and appreciate such upgrades that lower energy bills and maintenance costs in the long run.
Types of Double Glazing
Double glazing comes in various configurations to suit different needs and budgets. Here are some common types:
uPVC Double Glazing
Made using uPVC (unplasticized polyvinyl chloride) window frames filled with double or triple glazed glass panes. These are the most popular choices in many regions, offering durability and cost-effectiveness. Thermal efficiency is also quite high.
Timber Double Glazing
Timber-framed double glazing features a classic appearance that suits cottage-style homes or rustic interiors well. Lightweight construction using various wood types is common. It requires proper treatment and maintenance against moisture. Offers reasonably good insulation during all seasons.
Aluminium Double Glazing
Sleek aluminum frames hold the double-glazed units in such windows. Aluminium itself is lightweight, weather-resistant, durable, and recyclable. Further enhancement with thermal breaks reduces heat flow through the frame. Suited for contemporary architecture that calls for slim and minimal designs.
Double Glazing Installation Process
Installing double glazing typically involves the following steps:
Consultation
A preliminary inspection and measurement of your window areas are done. This allows for recommendations on appropriate double glazing products and customization options. You can clarify priorities, concerns, and budget at this stage.
Measurement and Planning
Detailed measurements are taken, and plans are drawn up for production or order placements. Taking them out may be needed first to size precisely for total window replacement. Expect 1-2 weeks for this planning process.
Ordering and Delivery
Based on agreed drawings/specifications, your bespoke double glazing system is ordered or manufactured. Delivery typically occurs after 4-6 weeks. The frame varies by product type and supplier lead times.
Removal of Existing Windows
If undertaking complete window replacement, the first step is taking out old single-glazed frames. This is performed with care to avoid damage to adjoining structures. Space is cleared to accommodate new double glazing fittings.
Installation of New Units
Prep work, like opening adjustments, is done before placing the insulated glass panes into window frames. Fastening and sealing are checked closely for alignment, stability, and insulation continuity. Any finishing like painting is completed.
Finishing Touches
Installation debris and dust are cleaned thoroughly. Hardware like handles, locks and any accessories chosen are fitted. Operation is tested to ensure smooth open/close function. User manuals for care and maintenance are provided.
Factors to Consider When Choosing Double Glazing
Before making your decision, consider the following factors:
Your Budget
As a home upgrade, double glazing requires considerable investment. Pricing is generally by the square meter and influenced by window sizes, customizations, and enhancements chosen, e.g., triple glazing. Energy savings in the long run offset costs. Prepare for approx. expenditures between $600 to $1500 per window, depending on specifics.
Energy Efficiency
The biggest motivation for most homeowners is enhanced insulation and lower heating/cooling costs. Thermal efficiency differs widely between types and models – from U-values of 1.4 to 0.7. Lower U-values indicate better performance. Choose A-rated double glazing for best results.
Noise Reduction
Acoustic insulation quality should match your needs, too. Traffic noise, flight paths, and other exterior factors may call for double-laminated glass, casement style, or triple glazing for higher noise reduction. These dampen sounds by 40-50 decibels compared to standard double glazing’s 25-35 dB rating.
Security
Basic double glazing already enhances security by making intruder access tougher. Additionally, laminated glass panes resist blunt force much longer. Lock types like key locks and child safety locks also improve protection. Alarms can also be incorporated for maximal security.
Style and Aesthetics
Frame material and finish determine overall visual appeal alongside glass color, bevelling, etching, and obscuration choices. Contemporary aluminium in black creates an edgy look while classic wood lends traditional earthiness. Go for bevels, etched patterns, or color tints if you want to make a stylish statement.
Warranty and Guarantees
Reputable manufacturers offer at least 5 years on the structural frame and 2 years on glazing units, but extended warranties are advisable for long-term security. Ensure the installer also guarantees their fitting workmanship for at least 5 years. This ensures any defects or leaks from poor sealing are covered.
Conclusion
Upgrading existing single glazed windows to modern double glazing is an investment that pays dividends in the long run through drastic savings on monthly energy bills and reduced building wear and tear. Alongside better aesthetics, functionality, comfort, and property value, it is a smart upgrade that makes every home a higher-quality living space for occupants. Use this guide and consult experienced installers for flawless double glazing execution tailored to your needs.
