4 Gaymer Memorial Cottages, Attleborough, Norfolk
Blog 2 (25.11.10)
Things are progressing well at Attleborough with completion anticipated in early January (1 week behind programme). The site is very busy at the moment with several trades onsite this week including plumbers; window fitters; electricians; MVHR and PV installers, etc. 1st fix electrics and plumbing are ongoing with installation of PV due later this week.
Following our fortnightly site meeting on Tuesday we managed to give the future tenant (Margaret Lawrence) a guided tour of the property and explained progress to date:
Existing finishes have been removed and 80mm spacetherm insulation fitted to existing floors and external walls. The insulated wall build up receives an air-tight membrane and battens to create a service void for cables/ pipes thereby improving long term flexibility and minimising future risk of puncturing the envelope. Photographs show the underside of the existing roof lined with OSB and taped at junctions with Pro-Clima sealants/ adhesives to provide an air-tight envelope.
We have come across a few technical issues which have required minor amendments. These include the discovery that the property is in fact cavity rather than solid wall construction! We will of course be injecting insulated cavity wall fill to all areas which will further improve the already impressive U values of 0.15. In addition the short length of existing flex to the original meter means that we have been forced to reduce the thickness of wall insulation behind this small area.
This property was until recently void and the client (Hastoe Housing Association) is taking the opportunity to upgrade the property to Decent Homes standard including relocation of the bathroom and reorganisation of the kitchen.
