This nice door was made for The Old Brewhouse when it was a farm service building where nobody lived.
It has thin planks with cracks between, and is a heat sink in the house during winter, no matter how much draft proofing is stuffed in and around it.
As a listed building, we’re supposed to make a formal application to the council heritage department and pay a fee if we wish to replace it. Our solution was to leave the old door untouched, apart from a few new screw holes, and build an identical door on the inside of it to double the thickness, cover the cracks and improve its thermal performance. It should make a noticeable difference to the warmth of the room in midwinter.

Early on, we filled panels where the clay had disappeared with new wattle and daub. This year we have switched to a new plan: these panels, which had been filled in the last 30 years with Thermalite blocks and broken bricks, have been made into a breathable hemp sandwich.
We lined the outside of the building with Savalit woodwool boards (as described before), then plastered them with haired chalk and lime mix bought from Anglia Lime. We used battens to fix Savalit boards on the inside, recessed just enough to take the plaster, and gave them a thinner layer of chalk and lime plaster, also with hair. In fact, internally, Savalit boards can take an extremely thin, almost skim coat of haired lime plaster and still look good.
In the middle we put two 75mm layers of natural hemp batts, Continue reading “Hemp insulation”
Our thinking has moved on from when we started work in 2009 and 2010. One advantage of repairing a house very slowly is that it gives time to learn as you go along.
This applies particularly to the question of which materials to use when repairing walls and infill panels and when plastering and rendering, and to the question of energy efficiency. Continue reading “Moving on – chalk and woodwool boards”
