The Renovation of the
London officePart 1: Insulation (Summer 2008)
A story of mud, sweat and sears
The office building
Existing Exterior Walls:400mm Brickwork
U-value of 1.4
Wood fiberboard Insulation with Clay plastering
Wood fiberboard Insulation is:
> Made of waste wood> Renewable Resource> Bio-degradable> Good conductivity & insulation> Adds some thermal mass> Breathable
Clay plastering:> Made of earth / clay> Natural & Renewable Resource> Bio-degradable> Low embodied energy> Breathable> Doesn’t trap moisture> Eliminates the need for paint
reduces time & cost & toxicity
Insulation Effect:
400mm Brickwork (existing)100mm Wood fiberboard7 mm Clay Plaster; 2 layers
U-value drops from 1.4 to 0.325
The old insulation was removed
The radiators were cut and drained
The walls were completely bare
1 ton of insulation boards arrived
…and 1 and ½ tons of clay
They were brought in…
…and packed the whole room
The boards were cut to size…
…with a jigsaw blade
The 100mm boards were drilled in…
…with a 200mm long drill bit
The boards were nailed to the wall…
…with plastic plugs…
…in the corners and the centre
The walls were less bare
The clay was placed in the buckets
…water was poured…
…to mix the clay plaster
The wet lining began…
…to cover the entire room
Mesh was cut to size…
…to hold the clay plaster…
…and was covered with white plaster
The heating & electrics were reconnected
The window sills were put back
The office was ready!
and now occupied.
The Renovation of the
London officePart 2: Biomass Stove (Nov 2010)
The thermal store arrived…
…was craned into position…
…and lowered into the basement
…and installed into its final position
The flue was installed…
…from the basement to the roof.
The stove arrived…
…was craned into position…
…and installed in its final location.
The existing beam was 60 years old & could not handle 1 ton of pellets
So it was removed…
…and replaced with a new one.
1 ton of pellets arrives every month in winter for 6 months
The pallet is lifted from the pavement…
…to the basement.
The final result!
