2. What is the predominant material of the exterior walls?
Select the primary material used in the construction of exterior walls. In case of a doubt, consult the occupants of the dwelling. If in the construction there is more than one material, only make reference to the one used with the greatest proportion.
The following explanations will help you determine the nature of some materials:
Brick, ticholos, or finished blocks. The ticholos are hollow "blocks" (of bigger dimensions than those of a brick). The level of completion refers to the exterior part of the wall, it is said that they are finished when they possess mechanisms of thermal insulation and protection against moisture, like waterproof plastic, asphalt, sand, Portland cement, etc. Rock walls are included in this category.
Brick, ticholos, or unfinished blocks. It is said that they are unfinished when they lack exterior thermal insulation and/or protection against moisture.

Light materials with coating. This deals with smooth or corrugated panels of fibro-cement or new panels, that are also known as their brand name like Dolmenit, Eternit, Fibrolit etc. When they have some type of thermal insulation and or insulation against moisture they have a coating. In general if they have"No"outer covering they may have insulation on the inside as plastic foam.
Light materials without coating. These are like the previous case but have"No"thermal insulation or insulation against moisture. If the walls are made of wood it should be classified as light material without coating.
Adobe. This deals with walls made of clay.
Waste materials. Waste materials are those of little or"No"value that were previously used for other ends (plastic bags, wooden boxes, tin cans) or materials used for construction but were already used and deteriorated (pieces of chopped metal, pieces of broken concrete). Generally in constructions of this type their parts have come loose and the open joints are exposed to wind penetration.
