As designers, engineers and facility owners pursue solutions that align with New Zealand's low-emissions building objectives, Efaflex doors provide an optimal combination of thermal efficiency, airtightness and intelligent system control.

Minimising energy loss at critical thresholds 

In temperature-controlled environments such as cold storage, food processing, and logistics facilities, slow or inefficient doors can result in substantial energy loss. Efaflex doors address this challenge through rapid open and close cycles, minimising air exchange and limiting thermal drift between zones. Their advanced construction incorporates low U-values (from 1.5 W/m²K), helping maintain stable ambient conditions in production, warehousing and cleanroom environments. Options for double-walled laths or insulated panels further enhance thermal performance.

Certified airtightness and thermal insulation 

Efaflex doors achieve airtightness ratings up to Class 4 in accordance with EN 12426, contributing to more stable indoor conditions and enhanced HVAC efficiency. Superior air tightness is achieved through precision-engineered seals, flaps and tensioned systems that maintain consistent performance throughout their service life. This optimises energy retention and reduces operational heating and cooling demands.

Engineered for sustainability 

Efaflex integrates sustainability principles throughout product development and manufacturing processes. The doors are built for exceptional longevity, featuring robust components engineered for guaranteed high lifecycle performance. Products are nearly 100% recyclable and manufactured from premium materials with fully traceable origins. Third-party certifications, including those from ift Rosenheim and Environmental Product Declarations (EPDs), validate product quality and environmental stewardship. Efaflex actively participates in sustainability initiatives and maintains strategic affiliations with:

• EcoVadis (Silver-rated for sustainability)
• DGNB (Member since April 2025)
• LEED and BREEAM compatibility for green building standards
• UN Global Compact
• Tacto (verified sustainable supply chain audit)
• Energy Efficiency Through Intelligent Design

The exceptional speeds and sealing performance of Efaflex doors significantly reduce warm and cold air exchange. This directly lowers a facility's operational energy consumption and associated emissions. Integrated sensor technology minimises unnecessary hold-open periods and prevents false activations. Energy performance can be accurately modelled using the EFA-EnergySaver tool, which provides detailed estimates of energy, CO₂ and cost savings compared to conventional sectional doors.

Supporting low-carbon design outcomes 

By reducing HVAC and refrigeration loads, high-speed, well-sealed doors contribute to enhanced building energy performance. In new developments or retrofit projects, Efaflex doors can facilitate compliance with Green Star NZ or NABERSNZ rating systems. Comprehensive performance data and documentation are readily available for compliance reporting.
