KILON LEC Multiwall and KILON LEC Solid Sheet
Polycarbonate sheets made with 50% post-consumer recycled content, manufactured in Ireland with 100% renewable electricity, and backed by third-party verified Environmental Product Declarations.
The KILON LEC range delivers high-performance daylighting polycarbonate with lower embodied carbon than the standard Kingspan versions of the same product, while maintaining durability and performance.
Our Two LEC Products
KILON LEC Solid Sheet
For glazing, screening and safety applications. Both are made at our Daylighting Centre of Excellence in Kingscourt, Ireland.
Recycled content
Made with 50% post-consumer waste
The resin in KILON LEC is a 50/50 mix of post-consumer recycled polycarbonate and standard polycarbonate. The post-consumer waste is collected, cleaned, sorted and shredded before being blended with prime polymer at our facilities.
- Less Virgin Plastic: Half of the resin comes from post-consumer waste.
- Renewable Manufacturing: Our Kingscourt plant runs on 100% renewable electricity, with 1,440 rooftop solar PV modules (540 kWp) on site.

Polycarbonate Multiwall Sheet
KILON LEC Multiwall
Up to 56.4% lower embodied carbon (A1–A3) than standard KILON Multiwall, a saving of 2.98 kg CO₂e per kg of product.
KILON LEC Multiwall panels are made from high-performance polycarbonate resin with 50% recycled content. Their multiwall structure is light, insulating and weatherproof, letting in natural daylight to reduce the need for artificial lighting and supporting lower heating and cooling demand.
- Available in 6 mm, 8 mm and 10 mm
- U-value from 1.6 to 3.49 W/m²K, depending on thickness
- For rooflights, roofs, vertical glazing and facades
- 35.6% to 48.7% lower embodied carbon across the full life cycle (A–C), depending on end-of-life scenario
- Verified according to EN 15804+A2.

FAQs
Common Questions about KILON LEC
What does LEC mean?
LEC stands for Lower Embodied Carbon. LEC products have lower embodied carbon than the equivalent standard Kingspan product, proven by comparing third-party verified Environmental Product Declarations (EPDs).
How is the carbon reduction achieved?
Two changes drive the reduction: the polycarbonate resin contains 50% post-consumer recycled content, and the raw material is sourced from suppliers closer to our manufacturing site in Ireland.
Are the figures independently verified?
Yes. Each KILON LEC product and its standard equivalent has an EPD published by Institut Bauen und Umwelt e.V. (IBU), externally verified to ISO 14025 and EN 15804+A2. You can use these EPDs in your project carbon assessment.
What do A1–A3 and A–C mean?
These are life cycle modules defined in EN 15804. A1–A3 is the product stage: raw materials, transport to the factory and manufacturing. A–C is the full life cycle, adding transport and installation (A4–A5), use (B) and end of life (C). Full life cycle results depend on the end-of-life scenario, such as recycling, incineration with energy recovery or landfill.
Which building certification schemes can KILON LEC support?
Product-specific, third-party verified EPDs can be used as evidence for embodied carbon credits in schemes such as LEED, BREEAM and the Home Performance Index. Talk to our team about your project requirements.
Can KILON LEC be recycled at end of life?
Yes. KILON LEC can be recycled into polycarbonate granulate, and the EPDs include a recycling end-of-life scenario.
