Glass options and glazing performance
The right glazing package changes how a room feels, sounds and performs across seasons. Choices here strongly affect thermal comfort, safety and long‑term value.
Standard, Low‑E, toughened and laminated
Standard glass gives basic daylight and clarity at the lowest price. It suits sheltered rooms where security and high insulation aren’t priorities.
Low‑E coatings reflect infrared heat and improve energy efficiency, reducing heat loss in winter and heat gain in summer. This option raises the upfront price but often pays back via lower heating and cooling use.
Toughened and laminated panes add safety and security. Toughened glass resists impact; laminated glass holds fragments and improves acoustic performance. Both are recommended for ground‑level openings and doors.
Gas fills and advanced coatings
Inert fills (argon, krypton) and magnetron coatings boost insulation by cutting heat transfer across the gap. They also help reduce condensation by keeping the inner pane warmer.
Thicker panes, laminated interlayers and optimised air or gas gaps improve noise attenuation for homes near traffic or activity.
- Match glass choice to orientation, shading and local climate for best results.
- Thermal, acoustic and safety goals often overlap — a balanced spec delivers multiple benefits.
- Heating and cooling efficiency relies on frames and airtight installation as much as the glazing itself.
For advice on the best glass package for your home, call 0440 138 658.
Frames and finishes: uPVC, aluminium and colour choices
Frame selection affects energy performance, appearance and long‑term upkeep.
Choosing between uPVC and aluminium shapes thermal performance, maintenance needs and delivery times. The right pick also supports your overall design and perceived quality.
uPVC vs aluminium: cost, insulation and maintenance
uPVC is durable, low maintenance and offers strong thermal performance. Standard colours are White, Cream, Golden Oak, Anthracite and Black Smooth. Special‑order finishes expand options but can extend lead times and add to cost.
Aluminium is slimmer, ideal for modern frames and large spans. Powder‑coated finishes give a full palette and excellent durability. Thermal breaks and quality gaskets are vital to preserve efficiency.
Popular colours and finish effects
Wood‑grain uPVC and powder‑coated aluminium mimic timber tones while keeping low upkeep. Consistent finishes across doors and windows create a cohesive facade.
“Match material and finish to climate, security needs and long‑term maintenance goals.”
Feature | uPVC | Aluminium |
Thermal performance | High with multi‑chamber profiles | Good with thermal breaks |
Maintenance | Low | Low to moderate |
Colour options | Standard palette + special order | Full powder‑coat range |
Best for | Energy efficiency, coastal UV stability | Large spans, slim sightlines |
Security improves with robust frames, multi‑point locking and laminated glazing. For samples and a side‑by‑side specification comparison, call 0440 138 658.
Installation, site work and hidden extras to budget for
Site work and installation often decide the final invoice more than the product tag. A tidy plan at measure stage cuts surprises and keeps the project on track.
Delivery, removal and disposal of old units
Typical exclusions such as delivery, hire of access equipment and disposal of old windows can add significant sums. Ask for these line items up front so you see the full costs.
Structural repairs, hardware upgrades and compliance
Removal can reveal rot in frames, lintel movement or degraded surrounds. These repairs, plus upgraded locks or safety glazing, will change the final sum.
- Confirm site access, parking and power to avoid variations.
- Discuss noise goals — acoustic glazing or seals affect installation approach.
- Coordinate trades if plastering, painting or cladding interfaces are needed.
Best practice: get a written, itemised quote that lists labour, materials and provisional sums and states warranty terms. Avoid hidden extras — ask for a line‑by‑line quote at 0440 138 658.
Item | Common exclusion | Impact |
Delivery | Not always included | Adds to price on remote sites |
Removal & disposal | Often extra | Site clean‑up and waste fees |
Structural repair | Measured on site | Can delay schedule and raise cost |
Hardware & compliance | Upgrades billed separately | Improves safety and warranty |
Repairs, replacements and how existing conditions affect cost
A clear site inspection tells you whether repair or full replacement is the better value. Early assessment avoids hidden surprises and gives a fair schedule and price estimate.

When repairing old frames is cost-effective
Repair makes sense if frames are square and timber or uPVC has minor damage. Small rot pockets, loose seals or worn hardware can be fixed for less than a full swap.
Upgrading for longevity, security and performance
Significant rot, twisted openings or failing sills usually push the balance to replacement. Modifying a poor frame raises labour and material demands and increases total costs.
Key upgrade options:
- Replace single panes with laminated or toughened glass to lift safety and acoustic performance.
- Fit multi‑point locks and reinforced frames to improve security and durability.
- Upgrade seals and drainage for better thermal and weather performance.
“Request line items that separate repair allowances from new product prices to compare true value.”
Condition | Likely action | Impact on budget |
Minor damage | Repair seals & hardware | Low extra costs |
Moderate rot | Partial frame replacement | Moderate costs, improved longevity |
Severe structural | Full replacement | Higher upfront, lower lifecycle costs |

Double glazing vs single glazing: upfront cost and lifetime value
Choosing between single pane and paired‑pane glazing means weighing a higher upfront purchase against years of lower running bills.
Energy efficiency, comfort and noise reduction gains
Paired‑pane glazing lowers heat transfer and can cut heat loss by up to 50%. That reduces reliance on heating and cooling systems and improves comfort.
Rooms stay warmer in winter and cooler in summer. Condensation risk falls, protecting paint and furnishings.
Laminated or thicker panes improve noise control. For homes near busy roads, acoustic glazing often outperforms single pane options.
Impact on energy bills and property value over time
Energy bills can drop by as much as 30% with a well‑specified upgrade. Those reductions compound over years and help offset the higher initial outlay.
Property value and buyer appeal also rise; modern, efficient units typically boost resale by around 10% on average.
Feature | Single pane | Paired‑pane |
Heat loss | High | Up to 50% lower |
Energy bills | Higher | Up to 30% lower |
Noise reduction | Low | Good with laminated glass |
Condensation | More likely | Reduced risk |

FAQ
What factors most influence the price of double glazed windows?
Size, frame material (uPVC or aluminium), glass type (standard, Low‑E, laminated or toughened), gas fill and any specialised coatings are the main drivers. Installation complexity, site access and required structural work also raise the final figure.
What’s typically included in a quote and what’s extra?
A clear quote usually covers supply of frames and sealed units, delivery, basic installation and standard hardware. Extras often include removal and disposal of old frames, structural repairs, specialised finishes, powder-coating, upgraded handles or locks, and any council compliance fees.
How do uPVC and aluminium compare in price and performance?
uPVC often costs less and offers strong thermal performance with low maintenance. Aluminium can be pricier, especially with thermal breaks and powder-coating, but it gives slimmer sightlines and greater strength for large openings.
Which glass options help reduce energy bills and noise?
Low‑E glass with a warm-edge spacer and argon or krypton gas fill improves insulation and lowers heating demand. Laminated glass and thicker panes with gas fills are best for noise reduction.
When will replacing frames be more cost-effective than repairing?
Replace when frames are warped, corroded, or have widespread rot and when sealing has failed. New frames deliver better thermal performance, security and often lower lifetime maintenance costs compared with repeated repairs.
Do larger doors and stacker systems cost significantly more?
Yes. Larger sliding doors, stackers and lift‑and‑slide systems use heavier hardware, stronger frames and precision installation, so expect a marked price increase versus standard windows.
What hidden extras should I budget for during installation?
Budget for removal and disposal of old units, minor structural work, patching and repainting, scaffolding or elevated access, and upgraded locks or flyscreens. Also allow for waste disposal fees.
How do glass coatings and gas fills affect pricing?
Low‑E coatings and argon or krypton fills add to the unit price but improve U‑values and comfort. Toughened or laminated safety glass and acoustic laminates cost more but add safety and noise control benefits.
Will new glazing increase my property value and reduce bills?
Upgrading sealed units and frames improves energy efficiency, reduces drafts and noise, and often boosts market appeal. Over time, savings on heating and cooling can offset a portion of the initial investment.
How long does a typical replacement project take from quote to finish?
From accurate quote to installation completion, small projects can take 2–6 weeks. Custom orders, powder-coating or specialised glass may extend lead times to 6–12 weeks. Onsite installation for a single window may be a few hours; larger jobs take days.
What should I ask suppliers to ensure like‑for‑like quotes?
Ask for specifications of glass type, spacer, gas, frame material and thickness, hardware brand, installation scope, removal of old units, warranty length and what is excluded. Request thermally rated U‑values and acoustic ratings where relevant.
Are warranties and certifications important?
Yes. Look for manufacturer warranties on frames and sealed units and installer guarantees for workmanship. Ensure compliance with Australian standards for glazing and any energy-rating documentation.
How do regional markets — for example Perth — affect pricing?
Labour costs, supply access and demand vary by region. Perth can differ from eastern states on lead times and freight charges, so regional sample prices often adjust for local market conditions and installer availability.
Can I get a transparent fixed quote over the phone or do you need a site visit?
Basic ballpark figures can be given by phone, but accurate fixed quotes require site measurements, inspection of existing frames and discussion of finishes, hardware and access, often needing a site visit.
What phone number should I call for a transparent quote today?
For a clear, itemised quote, call 0440 138 658 to discuss specifications, warranties and lead times with a local supplier.
