This gap is where an EnerPHit retrofit actually gets won or lost. Get the airtightness detailing wrong here and no amount of insulation upstream will save your blower door test. Every junction, every service pe*******on, every joint between old masonry and new lining gets the same attention before it disappears behind the wall.

Not glamorous. But it’s the difference between a house that performs on paper and one that performs in winter.

Making our walls waterproof before we put in enough super fill which is a hydrophobic insulation. To avoid mould risk we need the outside skin of brickwork to be watertight and this water repellent does that job. Other options would be to paint or to render and paint, but we wanted to keep the aesthetics of a the face brick.

“Quality isn’t a result, it’s a process.” This was my favourite quote from the 28th International Passivhaus Conference in Essen, Germany. It perfectly sums up the craftsman’s mindset: delivering a quality home requires rigorous, well-thought-out processes from day one.
Here’s what’s happening on the global stage:
The 3.5°C Jump: While the world average rise is 1.2°C, areas like Innsbruck, Austria are already 3.5°C over the 1900 baseline. This is pushing active cooling to the forefront of Northern European design.
Efficiency in the Details: We looked at how pre-detailing—like airtighting beam pockets before installation—saves time and cost while ensuring performance.
The Retrofit Revolution: From Greek islands to NY firehouses, the EnerPHit standard is proving that we can retain the “embodied carbon” of existing buildings while hitting peak efficiency.
My favourite site visit? A 1937 neighbourhood undergoing a massive retrofit. They’re using prefab insulated facades (windows included!) and craned-in roofs to move buildings from ‘H’ to ‘A+’ class without moving the tenants out.
It’s inspiring to see the global drive to create healthy, comfortable, and efficient spaces.
