The Inquiry

Email excerpt from Martí Designs :

"We're restoring 19th-century windows in Eixample district. Need roller blinds fabric that:

Passes heritage council approval

Reduces interior heat by ≥60%

Installs without drilling (stone frames)

Traditional blackout fabrics rejected. Can LEAPKA help?"

Technical Assessment

Our engineering team identified three hurdles:

Non-Invasive Mounting: Existing frames couldn't support >400g/m² fabric

Aesthetic Compliance: Required exact color match to original stained glass

Micro-Climate: Sea air accelerated material degradation

The Solution: F2001 White

Phase 1: Virtual Prototyping

Created 3D model showing 5% openness mimicking glass transparency

Simulated thermal performance (62.7% heat reduction confirmed)

Phase 2: On-Site Testing

Outcome

Client testimonial:

"After 3 failed attempts with other suppliers, LEAPKA's sunscreen fabric saved the €2.3M project. The heritage council praised how the material preserved the building's character while cutting cooling costs 41%. Most impressive? The 360g weight caused zero structural stress."
