SK NOTE: I was thinking of putting some placeholder blocks here to indicate there was more content to come (rough example below). But that is being used quite a lot now in apps where content loads automatically - so would be pretty misleading and may lead to a user waiting for something to happen. So still thinking of a better idea here...

Side Lap Fastener

Side lap fasteners are required at mid span when girt centres are 1800mm or greater. These are essential to hold the sheet laps firmly in place and maintain a weather-proof joint. Use aluminium 4-2 rivets.

Insulation

Care needs to be taken when installing insulation with roof sheeting. When insulation thickness up to 50mm are installed the screws detailed in Table LR PF NC 001 may need to be increased depending on the thickness and density of the insulation. When the screw is properly tightened into metal there should be a minimum of three (3) threads protruding past the support being fixed in to. For timber the screw must penetrate the timber as much as the screws detailed in Table LR PF NC 001 do without insulation.

For insulation thicknesses greater than 50mm Fielders® recommend the use of a thermal spacer to help maintain Rw values as well as minimising any bulging in the profile caused by the insulation.
