- Carbon Sequestration: Trees take in CO2 as they grow, and this carbon stays locked in the lumber throughout its life as a window frame.
- Accreditations: To be really eco-friendly, wood should carry 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 process, wood is biodegradable and does not add to landfill crises.
3. Bio-Based and Recycled Plastics
While standard uPVC has faced criticism for its chemical structure, the industry has seen the increase of recycled polymers and bio-based plastics. These products offer the insulation advantages of plastic while mitigating environmental damage by repurposing existing waste.
4. High-Performance, Recyclable Glass
The glass itself has actually seen significant technological leaps. Modern secondary glazing typically uses "Low-E" (low emissivity) glass, which includes a microscopic metal oxide finish that shows heat back into the room.
- Recycled Content: Many manufacturers now include a high portion of "cullet" (recycled glass) into their assembly line.
- Vacuum Glazing: This is a more recent innovation where the air between 2 thin panes is removed to create a vacuum, offering the thermal performance of triple glazing with a fraction of the material thickness and weight.
Comparison of Secondary Glazing Materials
The following table offers a contrast of common products utilized in secondary glazing based upon their environmental and functional residential or commercial properties.
