FAQ
Frequently Asked Questions
- How do energy efficient windows reduce utility bills through double glazing technology?
Energy savings depend on the complete window, the building, shading and how heating and cooling are used. The advanced insulation properties maintain consistent indoor temperatures with less energy input, resulting in measurable reductions in electricity and gas consumption throughout the year.
- What makes energy saving double glazing windows effective in Perth's climate?
Energy saving double glazing is specifically engineered for Perth’s extreme climate conditions, featuring low-E coatings that reflect summer heat whilst retaining winter warmth. The advanced thermal breaks and optimised cavity design provide exceptional insulation performance that adapts to seasonal temperature variations effectively.
- How much can energy efficient double glazed windows save annually?
Energy savings depend on the complete window specification, the building, shading and how heating and cooling are used. Ask for a quote based on your existing openings and priorities; there is no fixed saving or payback period that applies to every home.
- Do energy efficient double glazed windows meet building efficiency standards?
Yes, energy efficient double glazed windows exceed current NCC energy efficiency requirements and can contribute to achieving passive house standards. Our advanced glazing systems provide superior thermal performance ratings that enhance overall building energy efficiency scores and compliance with evolving building codes.
- What energy efficiency features do double glazed windows offer?
Energy efficient double glazed windows feature advanced thermal breaks, low-E glass coatings, optimised cavity design, and precision weather sealing. These elements combine to eliminate thermal bridging, control solar heat gain, maximise insulation properties, and prevent air infiltration for optimal energy performance.
- How does energy saving double glazing windows compare to single glazing?
Energy savings depend on the complete window, the building, shading and how heating and cooling are used.
- Can existing windows be upgraded for better energy efficiency?
Penot installs complete replacement windows and doors with new frames and glazing. We assess the existing openings, access and any heritage or strata requirements before quoting. We do not offer glass-only upgrades into existing frames. Any preparation or structural work is identified during the assessment.
- What maintenance ensures optimal energy efficiency performance?
Energy efficient double glazed windows require minimal maintenance to maintain optimal performance. Regular cleaning of glass surfaces, periodic inspection of seals, and occasional hardware adjustment ensure continued energy efficiency. The quality construction maintains superior thermal properties with minimal upkeep requirements over decades.
