Other Practical Advantages During Foundation Work

• Fast, seamless application → no tapes or overlaps required.
• Closed-cell structure → foam seals perfectly around pipes, cables, etc.
• Compressive strength → withstands slab and backfill loads (200 kPa).
• Insulating capacity → λ = 0.026 W/mK; U-value = 0.13 with 200 mm thickness.
• Time savings → radon protection and insulation in a single application.
• Covers complex geometries without cutting → angles and irregularities handled with ease.

Documented Protection

S35-Z polyurethane has been tested by an independent laboratory at the University of Cantabria, showing a radon diffusion coefficient of < 1.0 × 10⁻¹³ m²/s, which corresponds to:

• 5 times more airtight than radon barrier membranes on the market (0.1 mBq/s with 50,000 Bq in the soil).
• 20 times more airtight than standard products (0.4 mBq/s with 50,000 Bq in the soil).
• Poliuretan Spray S35-Z: 0.02 mBq/s with 50,000 Bq in the soil.

Even with just 25 mm thickness, extremely low radon ingress is achieved.

An Alternative with Environmental Attributes

1. Contains recycled content (PET).

2. Uses renewable raw materials.

3. Polyol developed with blowing agents with very low Global Warming Potential (GWP).

4. Less waste and transport: the material expands 20–30 times its liquid volume, reducing packaging and transportation.

5. Solves multiple problems in a single application.

• • Addresses moisture, radon, insulation, and airtightness with one product and one step.
  • Fewer work stages, shorter construction time, and reduced resource use.

This initiative, carried out in collaboration with Kingspan Colombia and Promoambiental (the local waste management company), is part of a long-standing awareness campaign by Synthesia aimed at promoting collective action against global warming and environmental pollution.

With initiatives like this, Synthesia seeks to foster a circular economy and promote greater sustainability and environmental awareness. A big thank you to all the participants!

The celebration had especially significant moments, such as the recognition of those employees who have dedicated 25 years of their professional lives to Synthesia, demonstrating exemplary commitment and loyalty. Likewise, tribute was paid to the workers who shared their 60th birthday with Synthesia. A video was presented in which they recalled their anecdotes, stressing their valuable contribution to the company’s growth.

David Palleja, CEO of Synthesia, gave an inspiring speech highlighting the importance of teamwork, responsibility, and the values​​that have guided the company since its beginnings. During his speech, David reviewed Synthesia’s most important historical milestones, highlighting how dedication and collective effort have allowed us to overcome challenges and achieve great achievements.

With a motivating and encouraging tone, David invited all those present to look to the future with optimism and determination, betting on new challenges and projects that will allow us to continue strengthening Synthesia in the years to come.

Synthesia’s 60th anniversary was not only an opportunity to celebrate but also to reflect on the journey we have taken and reaffirm our commitment to excellence and innovation. Without a doubt, this will remain engraved in the memory of all those present as a symbol of the spirit that characterizes our beloved company.

This milestone represents another significant advancement after with implementing LCA’s capability in Polyester Polyols and obtaining in 2024 externally verified Product Carbon Footprint (PCF) for 57 Polyester Polyols.

By integrating certified bio, bio-circular, and circular raw materials into its Polyester Polyols, Synthesia is contributing to the Decarbonization across diverse PU markets, including RHM, CASE, Flexible, Footwear, and Rigid applications.

In addition, by providing transparent Sustainability data, we are fostering closer collaboration with our customers and suppliers in mitigating CO2 emissions along the entire value chain.

The ISCC Plus certification highlights the Synthesia’s commitment to sustainability and innovation, giving continuity to the circular and environmentally responsible projects based on Recycled and Renewable raw materials.
