Earth reel roofs
• This roof construction system is suitable for sloping and flat roofs.
• Its density and heat retaining capacity make it well suited for hot dry or highland regions, where days are hot and nights are cool.
• The main component is a reel, made by rolling long vegetable fibrous material (generally straw) and a wet clayey soil around a wooden spindle (3 - 5 cm 0, 80 - 100 cm long).
• The reels are laid between the timber purlins when still moist and pressed against each other, the space between them being filled with a fibre-soil mix.
• After drying, the cracks are filled with a mud slurry, on top of which a 2 cm layer of soil, stabilized with finely chopped fibres and lime is applied.
• Finally, the roof is covered with a bitumen roofing felt and a layer of sand or fine gravel.
• On account of the large proportion of vegetable fibres and timber, the risk of termite attack is great.
