Green Building & Retrofit

Green building and retrofit work pairs energy efficiency with fire safety. Industrial furnaces get thin high-temperature coatings that cut heat loss; existing buildings add fire wrapping and partition fills without major reconstruction. The aim is lower operating energy and stronger code compliance.

Green Building & Retrofit Application Scenarios

• Industrial furnace energy-saving coating — a high-temp insulation coating (≈0.03 W/m·K, rated to 1000 °C) applied to furnace shells cuts heat loss in retrofit projects.
• Industrial equipment energy layers — ceramic fiber on boilers and thermal pipes reduces standby losses.
• Building exterior insulation layers — ceramic fiber and other systems raise facade efficiency.
• Steel-structure fire wrapping — calcium silicate slows the temperature rise of structural steel, protecting load capacity.
• Fire-door cores — calcium silicate boards with high fire rating and stable structure.
• Fire partition walls — calcium silicate fills interior fire divisions for code compliance.

Green Building Insulation Standards

Sustainable and retrofit projects are judged on three axes at once: energy performance, fire safety and documented environmental impact. The certifications that specifiers ask for reflect all three, and insulation choices feed directly into the credit calculations.

• Energy codes — ASHRAE 90.1 and the EU EPBD — set minimum envelope performance and continuous-insulation requirements by climate zone; insulation is the primary control layer for thermal resistance.
• EN 13501-1, Class A1 — non-combustible mineral wool supports fire-safe, code-compliant envelopes, especially where continuous insulation crosses structural members.
• LEED and BREEAM — award points for optimized energy performance and for transparent material documentation, including Environmental Product Declarations (EPDs) and low-emitting, low-VOC products.
• EPDs and ISO 14025 / ISO 14044 — life-cycle assessments that let a project claim the Materials and Resources credits tied to responsible sourcing and embodied carbon.

We support green-building submissions with documented thermal performance, A1 fire classification and EPD-ready product data for our mineral wool and calcium silicate ranges.

How to Select Green Building Insulation

1. Target the energy code first. Meet or exceed ASHRAE 90.1 or EPBD envelope thresholds; continuous insulation that breaks thermal bridges is usually the fastest route to credits.
2. Keep the envelope fire-safe. Specify A1 non-combustible mineral wool for assemblies that cross structural members or sit in high-occupancy zones.
3. Document the material. Collect EPDs and low-VOC declarations early; they are required for LEED and BREEAM Materials and Resources credits.
4. Match temperature to the system. Ceramic fiber serves high-temperature equipment and facade retrofits up to 1430 °C; calcium silicate provides structural fire wrapping and durable partition fills.
5. Favor durability and low load. Lightweight, stable boards and coatings upgrade existing buildings with minimal added structural burden.
