Filling gaps at eaves and ridge
Foam fillers should be used to fill the gaps at the ridge and eaves ends of sheets. Eaves fillers fitted underneath the sheets whilst ridge fillers are fitted on top of the sheets and underneath the flashing*. Foam fillers are supplied in pairs with a ridge and eaves profile for each sheet.
For added protection foam fillers can also be bonded to the sheets using a waterproof sealant such as butyl.
Fitting foams at the ridge
*Whilst not advised, if you are not using a flashing at the ridge end of a building you can use a foam underneath the sheet. Please be aware that you will need to double the amount of foams ordered for box profiles.
