Stop Thermal Bridges at the Source: High-Strength PU Structural Thermal Breaks (600 kg/m³)

The "Hardest" Part of Insulation In Passive House construction, the biggest challenge isn't the wall—it's the mounting points. How do you attach heavy windows, curtain walls, or AC units without drilling through the insulation and creating a "Thermal Highway"? The Solution: You need a material that is structurally rigid but thermally non-conductive. Enter Hebei Woqin’s High-Strength PU Block.

Engineered for Load-Bearing (Verified Data) Based on our latest test report from the Academy of Building Research, this is not standard foam. It is a structural component.

1.Density: 602 kg/m³. It feels and works like hardwood.

2.Compressive Strength: > 8 MPa. It can support heavy structural loads without deformation.

3.Screw Retention: > 600 N (Board Face). You can drive screws directly into it to fix brackets and frames.

4.Thermal Conductivity: 0.080 W/m·K. While higher than soft foam, it is 10x better than the concrete or steel it replaces, effectively breaking the thermal bridge.

Key Applications

1. Passive Window & Door Installation

• Problem: Heavy triple-glazed windows need strong support, but steel brackets conduct cold.
• Woqin Solution: Use our PU Blocks as the Sub-frame or Mounting Block. It bears the weight of the window while isolating the frame from the cold concrete wall.

2. Curtain Wall & Facade Brackets

• Problem: Metal anchors penetrate the insulation layer.
• Woqin Solution: Place a High-Strength PU pad under every metal bracket. It acts as a Thermal Break Pad, preventing condensation and heat loss at connection points.

3. Equipment Foundations (HVAC / Solar)

• Problem: Heavy AC units on the roof compress standard insulation.
• Woqin Solution: Our blocks (Water Absorption 2.1% ) are waterproof and rigid. They serve as rot-proof, insulated bases for rooftop machinery.

Compliance & Safety

• Fire Rating: Class B1 (Flame Retardant), ensuring safety in wall cavities.
• Durability: Unlike wood, it does not rot, swell, or degrade over time.

Conclusion: The "Structural Bone" of Green Buildings Don't compromise your building's energy rating with poor mounting details. Switch to Hebei Woqin’s Passive Polyurethane Insulation Blocks. Strong enough to build on, warm enough to insulate.
