Advantages of Glass
01. Transparency
Glass is a transparent material that allows light to pass through, making objects behind it visible. It helps you visually connect with the outside world. Even when doors or windows are closed, glass allows natural light to flow in, which saves energy and reduces electricity bills. It brightens up the room and enhances the beauty of the home. Additionally, it can also boost the residents’ mood. Glass is an ideal way to bring nature in. It gives you a feel of the outside, even when you are sitting inside your home.
02. Dustproof and Waterproof
Glass has a smooth, glossy surface, which makes it dustproof and easy to clean and maintain. Another advantage is that it is waterproof. Thus, with the dual benefits of being both dustproof and waterproof, glass is mostly preferred in dusty and sandy areas.
03. Wide Range of Colours
Glass is available in a wide range of colours, and when glass sheets are combined in laminated or insulated units, their colour and appearance change. Laminated glass can be made with a wide range of coloured interlayers to provide exceptional lighting effects. These colours can also be combined with tinted and printed glass to produce different results.
04. Aesthetically Appealing
Using glass in the building instantly changes the visual appeal of the structure. It gives it a stunning and sophisticated look. The pattern on even one of the glass panes creates an interesting atmosphere inside the building. Glass adds a sleek and modern appearance to a structure effortlessly.

05. Recyclable
According to Catherine Soanes, Sara Hawker & Julia Elliott (authors of the Pocket Oxford English Dictionary), recycling means converting waste into a form in which it can be reused. The other benefits of recycling glass include saving energy, being cost-effective, reducing water and air pollution to a certain extent, and conserving natural resources.
Glass is 100% recyclable, and it does not degrade during the recycling process. Hence, it can be recycled repeatedly without compromising quality or purity.
06. UV stable
The ozone layer is gradually degrading; therefore, it is essential to use materials that protect us from ultraviolet radiation. Glass is UV-stable, which means UV rays do not affect it. Hence, issues such as cracking, discolouration, or disintegration do not occur. It lasts much longer than many materials like plaster, which are not stable against UV radiation.
07. Weather and Rust Resistant
Unlike most materials, glass is corrosion-resistant and is only chemically attacked under specific conditions. According to ‘N. Papadopoulos’ and ‘C. A. Drosou’ (authors of Influence of Weather Conditions on Glass Properties), the chemical composition of glass plays a key role in how it interacts with the environment. Glass is fully weather-resistant. It can withstand wind, rain, and sunlight while retaining its appearance and structural integrity. Additionally, glass does not rust, so gradual degradation due to chemicals or environmental exposure is not a concern.
08. Easily Moulded
Glass is a transparent, hard material that can be easily moulded into desired shapes. It is produced by heating sand, allowing it to be blown, drawn, or pressed into various forms. This makes it suitable for general glazing in buildings, shop fronts, doors, windows, and workshops. It is also used in furniture after being laminated with plywood or metal sheets. Hence, it is one of the most versatile materials used in construction.
09. Insulator of Electricity
An electrical insulator is a material that poorly conducts electricity. Glass is an excellent electrical insulator because it does not readily allow the flow of electric current. Due to the absence of free electrons, glass ensures safety from electrical hazards. Because of this property, it is used in ceiling lights, decorative wall lights, and various electrical appliances.
10. Sustainable Material
Glass is a sustainable and fully recyclable material that offers significant environmental benefits. It helps mitigate climate change and conserves natural resources. Its inert nature also contributes to safeguarding the health and well-being of occupants.
11. Visible Transmittance
Visible transmittance (VT) refers to the amount of visible light that passes through a glazing material. It determines how much natural light enters a building. This property distinguishes glass from other materials and is one of the reasons it has gained immense popularity.
Glass absorbs, refracts, and transmits light. It can be made transparent or translucent, adding exceptional beauty to buildings. It can transmit up to 80% of natural daylight without yellowing, clouding, or weathering.
12. Resistance to Abrasion
According to Christopher Gorse, David Johnston, and Martin Pritchard (authors of the Oxford Dictionary of Construction, Surveying & Civil Engineering), abrasion refers to the wearing away of one material by friction against another. Glass has excellent abrasion resistance, enabling it to withstand surface wear caused by rubbing or direct contact with other materials.
Besides the above-mentioned benefits, there are other benefits associated as well:
01. Glass is stable over a wide range of temperature. Hence, it can be used for the fireplace, high-temperature light lenses, and wood-burning stoves, cooking tops and high-temperature areas where low expansion is needed.
02. It does not get affected by air, water and most of the acids hence discoloration, alteration in the degree of shine, softening, swelling, the detachment of coatings and blistering will not occur. Glass also protects against outside barriers.
03. When used in the interiors, Glass can save the space. It gives a spacious look as well.
04. Glass is comparatively lighter in weight than the other materials. Thus, it reduces the dead load of a structure.
05. Glass proves to be an excellent material for thermal insulation, waterproofing and energy conservation.
Disadvantages of Glass
01. Cost
Manufacturing of glass is a highly energy-consuming process due to high temperatures required for processing the raw materials. Glass is an expensive material as compared to the other materials used in the construction industry. As a result, the total cost of the building may increase. Using glass in a building enhances the cost of security and privacy because of the transparency that it offers.
02. Brittleness
A material that breaks into pieces or can be easily reduced to powder form is known as a brittle material. Glass is a stiff, rigid, and brittle material. When it is subjected to stress, it breaks without significant strain. Broken pieces of glass may be sharp, and the chances of injury are very high.
03. Impact Resistant
Glass is less impact-resistant, so its ability to withstand an immediately applied load is very poor. It will break immediately under impact.
04. Etching on Glass surface
Glass is affected by external hydrofluoric acid; hence, etching may occasionally appear on the glass surface.
05. Corrosion Due to Alkali Solution
Glass is affected by alkali ions. Alkali solutions dissolve the glass surface, and if the supply of alkali is high, this type of corrosion occurs at a uniform rate.
06. Heat Transparency
Glass offers superior heat transparency; hence, it must be balanced with its relatively low R-value (energy saving). R-value measures insulation effectiveness – its resistance to heat gain or loss. The higher the R-value, the better the insulation against heat and cold.
07. Unsafe for Earthquake-prone areas
Buildings in earthquake-prone areas need to be specially designed to withstand horizontal loads and movements. However, glass is brittle; therefore, it tends to break or collapse quickly.
The use of glass is very dangerous in earthquake-prone zones. Unfortunately, there is no technological advancement that can make glass an earthquake-resistant material. However, with some costly treatments, it can be modified to a certain extent so that it can withstand small-scale earthquakes.
8. Heat Absorbent
Glass traps heat, which eventually warms the interiors and acts like a greenhouse. Therefore, it might not be suitable for buildings in hot regions. It increases the A/C load and energy consumption needed to maintain indoor temperature. Hence, it should not be used in hot/tropical areas without careful consideration.
9. Maintenance
In humid and dust-prone areas, dust particles stick to the glass surface, making it look dirty and shabby while also reducing internal lighting and transparency. You may believe that once you provide glass as a building façade, you won’t spend much on painting. But this is not the case. On the contrary, you may end up paying an equal amount for cleaning glass. Sometimes, it can even be as expensive as exterior painting. Moreover, a building may be painted once every five years, but glass must be cleaned every year.
10. Glare
The façade is an elegant component that helps define the architectural aesthetics of any building. It also plays a crucial role in energy performance and interior function. However, glare is a significant problem in glass façade buildings. As technology improves, various options for reducing glare are becoming available for incorporation into building facades.
Final Thoughts
In a nutshell, “Glass bridges the gap between spaces, enhances the quality of space, transmits sufficient light, and also contributes to saving energy. The appropriate choice of glass can even improve the energy efficiency of the building,” says Jelena Savic et al. (2013), published in Architectural Glass: Types, Performance and Legislation. Glass has proved to be a building material that inspires designers to use it while creating various design forms and spaces. The above-mentioned advantages and disadvantages of glass as a building material will help you decide when, where, and how to use it for your sweet home.
