Description And Analysis Of Products Used In Construction

Next and synthetically, we offer a global view of what materials are commonly used in the construction sector and what negative impacts they cause on the environment, to have an approximation to the problem and be able to propose the corrective measures that lead us to a sustainable consumption trend in the construction sector.

The classification of construction products according to the construction elements where they are located in what we are going to consider describing them because although they are similar products, there are differences derived from the requirements depending on the use and the solicitations to which they are subjected. During the useful life.


The envelopes are the building systems that make up the facades and roofs of buildings, and that has the critical mission of protecting them and generating interior living spaces.

In the late nineteenth and early twentieth century, the new architectural languages imported from Europe, promoted the reduction of the dimensions of the envelope and the construction of flat roofs, which led to the necessary use of waterproofing and insulation, and the need for use of active conditioning measures to guarantee the comfort of buildings, forgetting the traditional bioclimatic resources.

In the construction of roofs products derived from ceramic materials and concrete are used, requiring waterproofing sheets flat roofs (1-5% slope) and inclined roofs of slight hills according to roofing material (CTE HS1), in addition to insulation material according to climatic zones.

The traditional massive facades are constructed of ceramic brick or lightened concrete block, taken with cement mortar. From the second half of the twentieth century, to avoid energy losses and moisture condensation, they began to introduce insulation materials, housed in air chambers or fixed to the wall on the outside of the building.

The most modern facades, promoted by the CTE DB HS1, include metal profiles for anchoring cladding pieces, insulation elements, and interior layers.

The Impacts Associated With The Envelopes Are Characterized By:

    Constituent materials, thicknesses of construction systems, and weight.

   Percentage of holes in the facades and roofs.

   Energy saving in the use phase of the building.

Maintenance of the envelope and durability.

The insulation is achieved by constructive provisions, air chambers, low-density materials, or with specific reinforcement products.
