DIY - Insulated Plasterboard - Will BC Accept?


iSelfBuild

Recommended Posts

Just had a price for 25mm insulated plasterboard @ £27.00 a sheet 

 

Is there any reason why we can't just fix 25mm Recitcel to our rafters, tape all the joints with foil tape and then screw the plasterboard through the insulation onto the rafters?

 

Will BC accept that or is there a condensation risk because it's not bonded seamlessly? 

 

There is 100mm Recitcel between the rafters as well.
