Baseline measurements
Air leakage and improvements
Draft Stripping
Improvements tested in lab at Glasgow Caledonian
Existing options – shutters & blinds – gave significant improvements
Improved shutters – U value of 1.8
shutters, curtains and blinds – reduce heat loss by 62%
Secondary glazing
Secondary glazing : U Value 1.7
new sealed units within existing sashes
vacuum DG panes – made in Japan
 
Energy efficient but looks and performs well
Thermal properties of Mass Walls
Monitoring equipment
Castle Fraser – U Value 0.8W/m 2 K for mass walls
Lab testing as well CGU Test Chamber 550mm Locharbriggs Calculated U Value 1.4 W/m2K Measured U Value  1.1 W/m2K
Scottish winner 2009 Cottage on  Skye, U Value 0.6
So what to do with a mass wall? Intervene here? Or here?
Insulation behind lath and plaster
bonded polystyrene bead U value improvement 68%
Calcium silicate board
Aerogel blanket
Aerogel with plaster finish
Interior of tenement, Glasgow External wall U-value 1.00
breathable insulated board U value improvement 65%
cellulose fibre U value improvement 71%
Hemp board U value improvement 78%
Wood wool with clay board applied as finishing
Clay board ready for application of clay plaster
External Insulation Maybe not here…
But what about here?
Wood fibre insulation, Glasgow
With 2 coat render system beibng applied
Negative visual impact of external insulation
Is it worth lifting this?
Sheep’s wool pinned to under floor joists
Hemp board between joists held in place with timber runners
Stone floors – can this be improved?
hemp / lime-concrete insulated floor beneath stone flags
Concrete floors can be lifted and insulated lime concrete floor laid in its place
Lime concrete layer being mixed, laid and flags laid on top
Concrete floor insulation:  U-value 0.25 W/m 2 .k
Should be 250mm thick or more whatever material used
Dealing with coombes
Sheep’s wool between joists
Insulating between rafters using hemp / wool material
Door panels can be insulated to reduce heat loss
New insulated door to traditional pattern where original has been lost
