Market Development History
Until the early 2000s, the Portuguese market primarily used simple PVC strips or brush-based seals. These provided basic protection but failed under prolonged exposure to high UV radiation, leading to frequent replacements and poor thermal insulation.
Between 2010 and 2020, there was a shift toward EPDM (Ethylene Propylene Diene Monomer) rubber. This era saw the widespread adoption of the under door draft protection concept, focusing on reducing drafts in traditional Portuguese stone houses and apartments.
In the current era, the industry has transitioned to "Active Sealing." The introduction of the automatic door sealing strip has revolutionized the market, allowing for seamless transitions that drop only when the door is closed, combining aesthetics with maximum efficiency.
Future Development Trends
Smart-Responsive Materials
Future seals will integrate shape-memory polymers that automatically adjust their tension based on the ambient temperature of the Portuguese climate.
Eco-Circular Production
A move toward 100% recyclable thermoplastic elastomers (TPE) to align with Portugal's commitment to the European Green Deal and circular economy.
Hyper-Precision Customization
Utilization of 3D scanning for doors to create bespoke seals that eliminate even the smallest gaps in historic Portuguese architecture.
