Straw matting

Straw matting is a type of floor that prevents the creation of 95% of most types of filth that would otherwise be created on it.

== Summary ==
Straw matting is one of a few floors that slows down pawns to of their move speed. It is also very flammable. It is not just by far the most flammable flooring, but one of the most flammable structures in general. Precautions should be taken in case of fire in areas where this is a risk, but it can also be exploited by making intentional fire traps. When it burns it leaves burned straw matting behind.
Straw matting has a cleanliness of , which means a room entirely filled with straw matting will have a cleanliness of the same value. Cleaning filth from straw matting takes the normal amount of work.
=== Filth multiplier ===
Straw matting is the only floor with a filth multiplier. For straw matting the amount of filth deposited on it is reduced to only , meaning of filth that would be deposited is not.
Note: Even though the description states the filth is deposited and then disappears, this is not the case. Filth sticking to the feet of pawns will instead be deposited elsewhere, meaning using straw matting as a "dormat" is counter productive. At the time of writing it is unknown if this is a bug.
The filth multiplier is especially important for filth like animal filth, dirt, sand and trash. Some types of filth are excluded from this, however, and will be deposited at the usual rate. These include notably: blood, corpse bile, firefoam and vomit.
== Analysis ==
This type of floor should be placed in any enclosed area that animals, especially farm animals, are allowed to enter. Care should be taken however - while it may be tempting to give any hauling animals paths to the warehouse where they will create minimal filth, it also essentially provides a wick directly to the same warehouse full of valuable items in the event of a fire.
A compromise would be to use matting with "fire breaks", either non-flammable walls and doors or areas of at least 3-tiles wide of non-flammable flooring at least 3 tiles wide, to minimize the spread of any fire.
=== Cleanliness ===
 
For the purposes of cooking, as long as a room's cleanliness is above -2.0, then the chance of food poisoning will not increase. Straw matting's is significantly above this threshold. As straw matting only creates 5% of walking filth, it is a very work efficient way to creating "clean enough" kitchens. It takes much longer to reach -2.0 cleanliness with straw than with regular floor. 
However, for other rooms where cleanliness and impressiveness matters, such as hospitals and throne rooms, the beauty and base cleanliness penalties of straw matting are sufficient by themselves to justify the cleaning time to avoid.
You can pair this floor with steel or sterile tiles in areas where filth does not or cannot accumulate, such as under furniture or chairs. This increases the overall base cleanliness of the room, while retaining the filth repellent nature of the straw matting in traffic areas. Fences can be used to control the path cost on sterile tile making pawns prefer the straw matting instead
