Insulation over sarking boards.
Tiles on battens and counterbattens
19mm softwood sarking boards
Improved thermal and acoustic performance against over-heating and outside noise compared with conventional solutions
Fully vapour permeable construction without the use of membranes or vented cavities - no risk of interstitial condensation or rot
Simple and robust construction with few skilled operations
Materials are non-toxic, non-irritant and easy to handle for installers with zero emissions once installed
Construction has low embodied energy, low CO2 emissions in manufacture and waste can be composted.
Add airtightness paper over sarking boards Necessary if boards are ill-fitting
