Solving Thermal Bridges in Steel, Concrete & High-Rise Passive House

Passive House & High-Rise Steel Construction

Hebei Woqin Structural HD‑PUR — The Structural Thermal Break System That Ends Compromises

Thermal bridging is the single greatest threat to Passivhaus certification, UK Part L compliance, EPC ratings, and long-term building envelope health.

Traditional insulation is too weak to carry structural loads.

Structural materials carry loads but create fatal thermal bridges.

For decades, the industry has been trapped in an unsolvable dilemma — until now.

This is Hebei Woqin Structural HD‑PUR.

Core Combat Data (Tested & Certified)

8.115 MPa structural-grade compression strength (EN 826)

8.17 MPa flexural strength (EN 12089)

620N screw‑holding power (matches hardwood, EN 320)

Euroclass B1 fire rating (EN 13501‑1)

0.08 W/(m·K) rigid thermal resistance (EN 12667)

One material. Five critical building failures solved.

Your Battlefield. Your Solution.

Below are the 5 high-risk thermal bridge scenarios destroying European buildings — and the engineered fix from Hebei Woqin.

Battle 1: Steel Beam Through-Wall Connections

Steel Beam Cold Bridges: Achieving Part L Compliance with Structural PUR Thermal Breaks

For: Structural engineers | Passivhaus architects | Compliance officers

Steel beams penetrating walls act as thermal “cold pipes,” causing condensation, mold, and failed energy checks.

Our fix: A bolted thermal break that passes Part L without sacrificing structural safety.

Battle 2: Cantilevered Balcony Thermal Connectors

Balcony Thermal Connectors: Load-Bearing Insulation for High-Rise Passive Houses

For: High-rise developers | Balcony system integrators

Cantilever balconies act as “cooling fins,” draining heat from slabs and ruining energy ratings.

Our fix: A cost-effective thermal break that carries balcony loads and stops energy loss.

Battle 3: Rooftop HVAC Plant Supports

Rooftop HVAC Plant Supports: Eliminating Condensation Below Heavy Chillers

For: MEP/HVAC engineers | Commercial property managers | Roofing contractors

Heavy chillers cause roof damage or top-floor condensation and mold.

Our fix: A fire-safe structural support that protects roofs and stops ceiling dripping.

Battle 4: Rainscreen Cladding Mounts

Rainscreen Cladding Mounts: Using 620N Screw-Holding PUR to Stop Facade Thermal Bridging

For: Facade engineers | Cladding contractors | EWI specialists

Through-wall fixings create thousands of point thermal bridges; wood blocks rot.

Our fix: A high-strength, rot-proof fixing system that eliminates facade thermal bridging without penetrating the inner insulation.

Battle 5: Parapet Wall Thermal Breaks

Parapet Wall Thermal Breaks: Blocking the "Cooling Fin" Effect in Flat Roof Construction

For: Main contractors | Roofing specialists | Building envelope designers

Parapets act as heat sinks, causing corner condensation, mold, and energy waste.

Our fix: A structural thermal break that carries full masonry weight and seals the envelope.
