Roof Heat Insulation
Length: 50 Meters
Width: 1.2 Meter
Thickness: 5 millimetre
Single side Silver laminate
Used for keeping homes, go-downs, warehouses and churches cool.
Regular home use the recommended size is 3 mm thickness
It is easily installed in one application creating a vapour barrier, thermal insulation, and will also achieve high acoustic values, reducing road, aircraft, and outside noise.
Procedure

For optimal insulation, ensure a minimum air gap of 25mm between the Jumbolene underlay and the iron sheets. The underlay maybe laid horizontally or vertically under the purlins.
One can use either strainer wires or Aluminium strips.Installation Guide for a New Roof:
1. Attach the galvanised wires onto the trusses running parallel to the purlins. The galvanised wires should be 300mm apart.
2. Place the roof insulation on top of the galvanised wires ensuring that the ends of the sheets are held firmly and that the sheets run continuously from one end of the truss to the other.
3. When adjoining the next roll, make sure that 100mm overlaps the first roll. This should ensure that the product is creating a vapour barrier.
4. Where necessary cut it around any penetrations making sure a tight fit to minimize openings.

Installation Guide for an Existing Roof:
1. Place the roof insulation between the purlin and the galvanised steel strip and screw it onto the purlins using 1 inch self tapping steel screws.
2. When fixing the roof insulation onto the subsequent purlin, pull the sheet so as to achieve a tight and firm fit free of sagging.
3. When adjoining the next roll, make sure that 100mm overlaps the first roll. This should ensure that the product is creating a vapour barrier.
4. Where necessary cut it around any penetrations making sure a tight fit to minimize openings.
