Waterproof palm thatch roof
For a waterproof palm thatch roof, a distance of about 10 cm between the slats of the palm thatch is usually recommended. This spacing ensures that the palm thatch overlaps and provide sufficient coverage to prevent water infiltration.
Decorative palm thatch roof
For a purely decorative palm leaf straw roof, where waterproofing is not a priority, a larger spacing between the slats of the palm thatch roofs can be used. A spacing of about 25 to 35 cm between slats may be sufficient to create a decorative effect.
