SIPs quote

[Kevan Marshall]

Just had a quote for supply and erection of SIPs house, my house is 180sqm ground floor area with provision to convert loft 70sqm at later date, external walls 197mm SIP panels to give U value of 0.13 or 172mm SIP panels plus 25mm PIR internal insulation to give U value of 0.12, roof is of vaulted truss system with steels in to support and boarded out and insulated to 0.12, all supporting stud walls are supplied, posi joists are supplied for loft conversion and floor boarded out, all wall and roof locations made airtight and battened out for service void ready to plasterboard, all exterior areas made weather tight, all crane hire, delivery costs included, airtight test done after I fit windows, all paperwork done for building control, with quite a lot of structural support walls going in leaves me very few stud walls to put in after installation of screed floor, I am waiting on quotes from two other SIPs companies but does this seem a reasonable price at 100k?

 

kind regards,

Kevan.

What score do they say they will achieve with the airtightness test.
