1.0 Introduction

Wood as cladding in building production simply means the use of timber in building cladding. B. Wood siding, wood exterior walls, wood exterior windows, doors and frames.

Logging of timber in the construction industry brings a variety of tree species to natural forests, and in recent years, the planting of exotic tree species such as pine and eucalyptus has increased. Despite its abundance, timber resources are underutilized as they are a material to be avoided due to their unreliability, variability and unknown properties.

In general, timber research is academic and focuses on a few tree species, resources have not studied key indicators of timber strength such as flexural rigidity and flexural strength, and alternative strength is reported to be low. This is why wood users are reluctant to accept lesser-known woods. Limited research has been conducted to predict allowable stresses from poor deflection relationships. This is probably why timber users prefer timber that has been trucked. This unfortunately puts pressure on known timber species, leading the construction environment to declining timber resources coupled with global population growth, and the arbitrarily sought use of multiple timber species for quality control. I’m here. procedure.

The purpose of this study was to investigate timber utilization practices with a focus on analyzing the weaknesses and strengths of using timber as a cladding material in construction.

Wood is a cellular material made up of tiny cells called fibers or grooves, which have interconnected depressions or values ‚Äč‚Äčthat allow water and solutions to pass through the structure.

The word timber describes wood that has been cut for use in construction. Wood as a building material has many advantages. It is a heavy weight material that is easy to cut, shape and join using the relatively cheap and simple hand or power tools used in wood production. Timber is used in all parts of buildings such as decorations, doors, windows, frames, timbers, wall panels, floors and roof trusses. Wood is a very important material in construction production that facilitates the construction of buildings. As a building material with rational selection, treatment, fixing, and appropriate impregnation or protection, it has favorable weight to loss of elastic modulus and coefficient of thermal expansion, density and specific heat value. It is a relatively durable material compared to the life of most buildings, with wood burning at temperatures of around 3500 degrees, enough to last long enough in the event of a fire in most buildings. For a period of time, the coated outer surface of the wood protects the unborn inner wood. .

Wood is the largest renewable raw material in the building materials sector. As a building material, the availability of sound structural design of timber structures and the development of economical processing and presentation processes, coupled with the more efficient use of timber, has determined its application in construction There are specific characteristics that Inside a wooden building.

In general, wood offers many advantages in building applications such as aesthetics, workability, low cost per kg, high strength-to-weight ratio, excellent electrical performance, and low temperatures.

1.1 Research background

Wood research explored the use of wood in construction as one of the most important building materials. Wood has been used in construction in most parts of the world for thousands of years. It is a renewable and easy-to-use natural material. Wood is just one building material that offers positive benefits when used properly.

1.2 Problem Description

While observing and researching building materials, I found that wood is inexpensive as a building material. This means that wood is a cheap material in construction production due to the high cost of certain materials such as aggregate, sand, cement and roofing membranes.

It is difficult to compare the cost of wooden frames with other building materials. The actual construction cost is likely to be a few percentage points higher for a typical timber frame compared to brick or block, and architects and builders with less experience in timber frame construction may want to make sure their designs are correct. tend to raise prices to compensate for the extra time required for This project is a comprehensive wood study to determine the suitability and usefulness of wood as a building material. Although wood donations to construction companies in general are common, there are still many problems associated with the use of wood in construction. These issues include a lack of knowledge about how to treat wood and the unavailability of standard wood connectors. Economics in the use of timber, incompatibility of timber available on the market and many other problems associated with the use of timber as an external material in construction production in hot climates.

1.3 Objectives and objectives of the survey


The main purpose of this study is to assess the problems and prospects of wood as a cladding material in construction production in hot climates.


The purpose of this research is to:

1. Clarification of various problems and viewpoints of wooden buildings in exterior construction.

2. Determining the function of wood in building production.

3. Evaluation of the quality of timber used by contractors as external materials for construction production. 4. Identify factors that inhibit the effective use of wood as exterior materials in building production.

5. Suggest how best to minimize the problems associated with the use of wood in construction production.

6. Regain the need and value of wood as a building material.

7. Arriving at the natural quantity of building wood, i. H. Aesthetics.

1.4 Importance of research

This research activity will benefit a great many people. People who would benefit from this research are:

It serves as a resource for builders, architects, students, and many others.

Contractors will benefit greatly from this work as they will be made aware of the problems and prospects of wood as an external material in construction production in hot climates. This study is relevant for students who wish to use it as a basis for further research. It serves as a board to initiate further research. The data already collected and documented in this project will serve as a resource for students and as a reference for classroom work.

This work is also of great importance to individual citizens of the country who wish to learn more about the problems and prospects of wood as a cladding material in construction production in hot climates.

1.5 Research question

For this research work, the following research tasks were created:

1. What are the diverse issues and perspectives of wood in construction?
