Retrofit Project Overview
Asset Integrity Scotland are a retrofit insulation company based in Aberdeen that uses Sisalwool in most of their projects. In this particular project the aim was to help the customer stay warmer in winter and cooler in the summer.
Why Sisalwool
The majority of buildings that are retrofitted are traditional stone, so they chose to insulate with something that keeps with the original design aspect of the building by insulating with vapour open materials to ensure moisture is not getting trapped within the fabric of the building making it breathable. Essentially work with the building not against it.
Installation of Sisalwool
Internal wall insulation, room in roof and underfloor.
For internal wall insulation the walls are stripped back to the stone and the condition is inspected, then a stud frame is installed. Sisalwool is installed between the frame then an airtight vapour control layer followed by plasterboard.
For room in roof, any current plasterboard and insulation is striped back and condition is inspected to ensure there are no leaks or damage. Sisalwool is installed to the full rafter depth and an airtight vapour control layer installed followed by plasterboard.
In most cases a wood fibre over sheet is installed to combat thermal bridging.
