10mm vs 150mm: The Truth About Guy Martin's Retrofit Challenge

The "Bunker" Dilemma
This Monday, Channel 4’s Guy Martin: House Without Bills showcases the extreme engineering required to turn a standard UK home into a Passivhaus.
While the goal of "Zero Bills" is inspiring, the reality for many is daunting. To achieve these standards with traditional materials, you often have to line your internal walls with 150mm of insulation. In a typical Victorian terrace or a cozy semi, that means turning your living room into a bunker and losing thousands of pounds in floor space value.

Just as Guy Martin applies engineering logic to home problems, Woqin applies petrochemical-grade thermal technology to your living room.
Here is how you can solve the biggest retrofit headaches without the bulk.

1. The Space Revolution: 10mm ≈ 150mm Performance

The Challenge: Traditional mineral wool relies on trapped air and thickness (100-150mm). Worse, if it gets damp—a common issue in solid brick walls—its insulation value plummets.

The Industrial Solution: Silica Aerogel Insulation Blanket
We don’t rely on thickness; we rely on nanotechnology.

• Thermal Superpower: With a conductivity of 0.020 W/(m·K), a 10mm layer creates a thermal barrier that rivals much thicker systems in effective performance.
• Hydrophobic Shield: Unlike wool, our Aerogel is 99.7% hydrophobic. It repels water, ensuring insulation works perfectly even in damp conditions. 10mm of dry Aerogel beats 100mm of wet wool every time.

2. The "Thermal Putty": Ending Black Mould

The Challenge: Window reveals and beam junctions are "Cold Bridges." They are too tight for boards, so they stay cold, attract condensation, and turn black with mould.

The Industrial Solution: Advanced Silica Aerogel Insulation Coating

• Application: Apply it like a skim coat (thermal putty) on internal window reveals.
• The Result: It raises the surface temperature immediately. No Condensation = No Mould.
• Exterior Use: For rendered facades, it acts as a continuous "thermal skin" under the finish. By eliminating thermal bridges at critical zones, it improves the overall effective U-value of the wall assembly, targeting energy savings of up to 30%.

3. The Window Foundation: Graphite EPS Sub-frame

The Challenge: Installing heavy triple-glazed Passivhaus windows directly onto cold brickwork creates a massive thermal bypass.

The Industrial Solution: Ultra-High Strength Graphite EPS Sub-frame

• High Density: Compressive strength of 2090 kPa and screw holding force >2100N.
• Thermal Break: It isolates the frame from the masonry, ensuring the "warm edge" stays warm.

4. The Structural Breaker: Rigid Polyurethane (PUR) Blocks

The Challenge: What about the metal brackets for your rain canopies, satellite dishes, or external railings? Bolting metal directly to the wall punctures your insulation layer, sucking heat out like a radiator in reverse.

The Industrial Solution: High-Density Rigid Polyurethane Insulation Blocks

• Function: Load-bearing connectors buried within insulation.
• Benefit: They carry the load while cutting off the thermal bridge. No more cold spots where the bolts go in.

Summary: Industrial vs. Traditional
