Non-flammable thatched roofs

The potential flammability of thatch roof (or any other natural material, for example wooden shingles) is often a reason why homeowners do not decide to roof their houses.

They are right, the cane is flammable …

And they are wrong: we now live in times when science is capable of turning any flammable material into a non-flammable (even fire retardant) material (I hope we are one step away from inventing non-flammable safety matches).

In the past, Thatchers solved this problem by dipping straw into mud. It formed a hard, non-flammable crust on the thatched roof, so it was quite safe when faced with some smaller fires (chimney sparks, etc.).

Today you have many more possibilities of how to make your thatched roof also fire retardant.

The following fire protection methods for your thatch roof are worth considering:

Flame Retardant Sprays for Thatch Roofs

There are some substances available on the market, such as Flame Stop I-DS, which prevent the spread of flames by developing a chemically self-extinguishing reaction.

Most of them are available in the form of aerosols (spray).

Flame retardant aluminum sheets

As aluminum is a perfectly non-flammable material (it is a metal capable of withstanding high temperatures), even a thin sheet helps keep the interiors of your house thermally separated from the roof (this is the method that does not protect the roofing material itself , let it burn, if fire is your destiny, but it keeps the other parts of the house separate and thus safe from the burning roof).

Flame retardant blocks (straw blocks) They are generally used to fill in the spaces in the roof structure between the truss beams. The straw blocks are actually the rock wool blocks, again, that separate the thatched roof from other parts of the house.

Do you think that none of the methods mentioned above would protect your home from fire sufficiently?

Separately maybe they wouldn’t … but why don’t you combine them? You get a truly reliable, fire and water resistant, natural, eco-friendly and fresh looking straw material that lasts for years and can be quickly repaired at low cost.
