The Home Applications of Recycled Glass

It is estimated that 40 billion glass bottles are created every year, and 75 percent of those find their final resting place in a landfill. Glass doesn’t break down, but clever companies are finding ways to breathe new life into old glass. Companies like Vetrazzo and Gilasi offer product lines featuring recycled glass from soda and wine bottles, post-industrial waste and even demolished buildings. Mixed with resins, cement, epoxy and tinted binding agents, it can be used in your home in a number of ways.

Countertops of Beautiful Glass
The green movement is here to stay and people appreciate the green aspects of recycled glass countertops. You will love knowing that you did your part to keep glass out of the landfills, and you will also love how it adds light, color and drama to the kitchen. Durable and attractive, you won’t have to replace the counter for many years, and that’s another boost for the environment.

Mulch the Garden
Wood was always the traditional choice for mulch, and rubber has become a popular alternative. However, recycled glass may soon become the favored choice. Companies are now offering tumbled glass in nugget shapes that do not have any sharp edges. Ideal for mulching the garden, the recycled glass will never fade and you will never have to replace it. Slugs don’t like crawling over it, and you can choose mulch in a variety of colors.

Fill the Sandbox

Pulverized glass is an excellent replacement for sand. Transform your sandbox into a sparkling jewel, and use the crushed glass to cradle stepping stones in a stunning rainbow of color. It won’t have to be replaced like mulch, and it’s as stable as paving sand for your stepping stones.

Custom Pools and Aquariums
If you are building a custom pool and want an incredible look, consider the beauty of recycled glass. Worked into the concrete liner of your pool, the glass reflects light and adds glorious color to the swimming pool. If you love how the recycled glass looks under the water but aren’t adding a pool, consider adding the beautiful substance to your aquariums. The colors will add interest, and your fish will look even more attractive against this amazing and beautiful base.

Versatile Tiles

If you love the color of glass and also love how eco-friendly recycled glass is, then you are sure to appreciate versatile glass tiles. The tiles are available in standard sizes that can be used around the home. Place them on the backsplash for an incredible color addition, or use them on shower walls to reflect light and make the space feel larger.

There are many advantages to choosing recycled glass for projects around the home. The materials are brightly colored and brilliant. Durable and unique, they will add a beautiful and luxurious touch wherever they are used in your home. In addition to being beautiful and durable, you will appreciate that recycled glass is great for the environment. Glass does not break down in landfills, so it’s important that we all do our part to find other uses for those glass bottles, windows and other glass items.

Glass and Fire Safety

When designing a new building, we have to comply with a whole series of requirements regarding fire safety that are imposed by EU legislation. Construction materials used for partitions must meet the criteria of specific fire resistance classes, which for some architects can feel as a brake on their freedom of design. A glass partition can provide a solution here, given that even for the top fire resistance classes, a transparent solution is possible using glass.
EU legislation
EU legislation distinguishes a material’s reaction to fire and it’s resistance to fire. A material’s reaction to fire indicates how a material will respond to fire. A distinction is made between fire-resistant materials, inflammable materials and flammable materials. Materials are divided into seven Euroclasses: A1, A2, B, C, D, E and F, where A is the best classification. The following glass products are included in the list of materials that are assigned to class A1 without testing being needed: float glass, patterned glass, heat strengthened glass, thermally toughened glass, chemically toughened glass, glass with an inorganic coating, and wired glass.

Glass Buildings and The Environment

Here is another article from Thomas Hens on designing of glass buildings keeping in mind their impact on environment.

In our last issue, we discussed a number key factors to be taken into account when choosing facade glass. This issue will focus primarily on the environment and demonstrate that designers of glass buildings are also thinking about our planet.

We will be looking at three environmentally friendly construction methods:

  • Insulating buildings: cutting C02 emissions by reducing energy loss via glass.
  • Generating energy: cutting energy consumption by using glass as a construction component as well as to generate electricity.
  • Using sustainable materials and environmentally friendly manufacturing techniques.

An interesting and very useful article on glass selection for buildings by Thomas Hens, Technical Adviser, AGC Glass Europe.

Glass is a multifaceted material that has been used widely for centuries to embellish facades and interiors. In contemporary architecture, glass plays an even more important role. Used alone, it can add a personal touch to any facade. Of course, this would be impossible without the wide range of new products and innovations to have emerged on the market in recent years. But is everyone aware of these latest developments? And just how do you select the right kind of glass for a given project? These are precisely the questions that this article will attempt to answer. Over four issues, we will be discussing the various factors affecting your choice of glass with a view to delivering a safer, more economical and more environmentally friendly project, or simply one that improves living conditions.

Key factors

When choosing the ideal glass, you must take into account a whole raft of factors, chief among which are the insulation value (Ug value), the solar factor (g value), light transmission (LT) and appearance (colour, reflective properties). Glass choice really does have a significant impact on a building’s energy performance, meaning you should ideally choose the right kind of glass as early as the design phase. Glass must also meet different requirements for residential and office buildings, so the appropriate glass type must be selected separately for each given project. Continue reading

Spray Hard Coat Glass Vs CVD Hard Coat Glass

If somebody tries to sell you cheap reflective glass saying it is “Hard Coated”, the first thing you should ask is “Is it spray hard coat or CVD hard coat?”. Spray hard coat could be termed as a primitive and is relatively cheaper, in this one the chemical composition is sprayed over glass which would be in a semi solid stage (online process). Most cases, the coating tends to be uneven and deposition rate would be poor. In most cases the coated side appears yellowish.

CVD (Chemical vapor deposition in atmospheric pressure) on the other hand is far superior and the latest. Here, the chemical composition is vaporised and then allowed to deposit on semi-solid glass (online coating) in a controlled manner, achieving high deposition rate and the coating would be even. In most cases, the coated side would have a silver appearance.

It would be a disaster if spray coated glasses which come at cheap rates are used (especially when it is mis-sold with the name “Hard coated reflective glass”) in buildings. Below are some pictures for reference.

Glass Types for Building Envelope Products

There are typically four different glass types used in glazing products: From weakest to strongest they are: Annealed, Heat Strengthened, Tempered and Laminated.

1. Annealed glass is your basic non-impact glass type. It is used in applications where the required wind load is not so high and safety requirements are not a concern. When annealed glass breaks, it breaks in sharp chards.

2. Heat Strengthened glass is also a non-impact glass. It undergoes a “heat treatment” that increases it’s strength to twice that of annealed glass. It is used in similar applications to annealed glass but where the required wind loads are much higher. When heat strengthened glass breaks, it also breaks in chards.

3. Tempered glass is your basic impact glass. It undergoes a more aggressive “treatment” that increases it’s strength to four times that of annealed glass. It is used in “small missile” impact applications typically installed 30 feet or higher above ground and in safeguard applications. When tempered glass breaks, it breaks into very small cubes.

4. Laminated glass is your typical impact glass. It is a combination of two (usually) of the three previously mentioned glass types that are “laminated” together with an interlayer between them. It is typically used in “large missile” impact applications installed up to 30 feet above ground. When laminated glass breaks, it breaks based on it’s glass type make-up but is held in place by the interlayer…similar to a car’s windshield.

Low-e Coated Glass and the right usage

Here’s a short article which describes the right usage of Low-e coated glasses. Towards the last sentence of the article, it has been clearly stated that these glasses are used to prevent heat loss from the building in cold climate. But still the usage of these glasses have been mis-understood and are used in hot and humid climates, believing that they reduce the overall heat entering the building. True that they block long wave infra red radiation entering the building, just like they block them from leaving the building (which is why they are mostly used in cold climate).
