1950's refurb - mini event 2

As part of the Eco Houses Under Construction series, a second mini event was held on site at the 1950's solid wall house. (...mini events because it would be impractical to have many people present at one time).



Gil Schalom (the architect) started by talking about how the ground floor is being insulated. Then attention turned to the roof. Due to the obvious shortcomings of the roof in its present state, and the plan to carry out a loft conversion with dormer and change from hip to gable at the back of the roof, major work will be needed.


The wind whistles through the loft due to the deterioration of the roofing felt, and the loft insulation was thin and full of dust. These two things alone conspire to make the house much colder than it should be.

Had the condition of the roof been better, most of the existing structure and the tiles would have been preserved, and insulation placed between and possibly beneath the rafters. However, in this case, we've decided to renew everything so that it will last long into the future, and at the same time aim for a very air tight construction and super-insulate at rafter level.



Another 1950's feature we won't be retaining is the state-of-the-ark Baxi fireplace! It's funny to think that this is where Baxi must have started when you consider the range of systems they now offer (from gas boilers to ground source heat pumps, air source heat pumps, one of the first domestic "combined heat and power" systems, solar hot water and so on!)

  2. The windows will be passive house suitable triple glazed with insulation inside the wooden frames. The UK supplier is Green Building Store. The u value of the whole window is very low, and depends on the ratio of glass to frame... these will be in the region of 0.75 for the whole window with a lower u value for the glazing alone.
