<p><span class="em">B2 and B3-Construction Materials of the Roof and Outer Walls</span>
<br />Data on construction materials of the roof and outer walls provide information on the construction, replacement, and improvement of housing units. These items can be used as proxy variables to measure the economic condition of households.
<br />Moreover, data on these items can be used in the evaluation of construction statistics, programme implementation, and for estimating investments in housing construction. They can also be used to determine the number of households residing in structurally acceptable housing units.</p>
<p>Structural acceptability of housing units implies that these housing units are made of durable construction materials that will safeguard the occupants of the housing unit from adverse climatic conditions and provide protection and privacy.</p>
<p><span class="em">B2-Construction Materials of the Roof</span>
<br />The categories for the kind of construction materials of the roof are as follows:</p>
<div class="i1">[] Galvanized iron/aluminum<br />[] Tile concrete/clay tile<br />[] Half galvanized iron and half concrete<br />[] Wood<br />[] Cogon/nipa/anahaw<br />[] Asbestos<br />[] Makeshift/salvaged/improvised materials<br />[] Others, specify</div><p>Write "X" in the box opposite the kind of material used in the construction of the roof. This item can be answered through observation but if you are in doubt, ask the respondent on the material used mainly for the roof.
<br />If two or more kinds of roofing materials are used, report the material used in most part of the roof. Thus, for a house with different kinds of roofs, report the material used in the main portion of the housing unit (usually containing the living room/sala and bedrooms). Specify the kind of construction material used for the roof if it is not one of the aforementioned categories.
<br />Bamboo, when used as a roofing material, is included in the category for Wood. On the other hand, housing units in structures such as culverts, bridges, and others should have an "X" mark in the box opposite Makeshift/ salvaged/improvised materials.
