Insulation, Roofing & Waterproofing sourcing guide
Global B2B Sourcing of Advanced Insulation, Roofing & Waterproofing
The global building and civil engineering sectors rely on high-performance thermal insulation, weather-resistant roofing systems, and advanced waterproofing barriers to protect structures against environmental degradation and energy loss. BIGEXPORT helps buyers connect with suppliers for these products worldwide.
Buyers can submit Requests for Quotations (RFQs) for stone wool insulation, PIR/XPS boards, APP/SBS modified bitumen membranes, EPDM liners, and metal roof cladding systems.

Meeting International Standards and Specifications
When creating an RFQ, buyers can specify compliance with international building physics standards to ensure energy efficiency and moisture defense. Key standards and specifications to request from suppliers include:
Compliance with global standards (EN 13162, ASTM C578, CE, ISO 9001, ISO 14001).
High thermal resistance (R-value), Class A1 fire resistance, and superior UV/weather durability.
Custom membrane thickness options, customized thermal conductivity values, and complete system accessories.
Frequently Asked Questions (FAQ)
Are the insulation and waterproofing products certified for fire safety?
Buyers can specify fire safety certification requirements in their RFQ. Many suppliers can provide stone wool and specialized membranes that meet Euroclass A1 and A2 non-combustible ratings.
What is the difference between APP and SBS modified bitumen membranes?
APP membranes excel in hot climates due to higher heat resistance, while SBS membranes offer superior flexibility in cold weather environments.
Can manufacturers supply complete roofing systems including fasteners and underlayments?
Buyers can request fully integrated system kits. Many suppliers can provide these, including vapor barriers, insulation boards, waterproofing layers, and mechanical fasteners.
