- Sturdiness: Its resistance to corrosion guarantees that the frames last for decades, minimizing the need for replacement.
2. Sustainably Sourced Timber
For heritage residential or commercial properties or those seeking a natural aesthetic, wood is a top choice. When sourced correctly, wood is the most sustainable framing product offered.
- Carbon Sequestration: Trees absorb CO2 as they grow, and this carbon stays secured the lumber throughout its life as a window frame.
- Certifications: To be truly environmentally friendly, timber should bring accreditation from the Forest Stewardship Council (FSC) or the Programme for the Endorsement of Forest Certification (PEFC).
- Biodegradability: At the end of its long life cycle, wood is biodegradable and does not add to land fill crises.
3. Bio-Based and Recycled Plastics
While conventional uPVC has actually faced criticism for its chemical composition, the market has seen the rise of recycled polymers and bio-based plastics. These materials provide the insulation benefits of plastic while mitigating ecological damage by repurposing existing waste.
4. High-Performance, Recyclable Glass
The glass itself has seen substantial technological leaps. Modern secondary glazing often makes use of "Low-E" (low emissivity) glass, which includes a tiny metal oxide finish that reflects heat back into the space.
- Recycled Content: Many manufacturers now incorporate a high percentage of "cullet" (recycled glass) into their production lines.
- Vacuum Glazing: This is a newer technology where the air in between 2 thin panes is gotten rid of to develop a vacuum, providing the thermal performance of triple glazing with a fraction of the product thickness and weight.
Contrast of Secondary Glazing Materials
The following table offers a contrast of typical products utilized in secondary glazing based on their environmental and functional residential or commercial properties.
