Backpainted glass a hit for home décor

If you’re looking for a quick, cost-effective way to update your kitchen, consider backpainted glass or backpainted Plexiglas™. Backpainting does not require special tools, and you can complete backpainted projects in a few hours or days. You’ll want to use Glassprimer™ glass paint because ordinary paint won’t stick to glass.

Backpainted glass makes a great surface for backsplashes, walls and cabinet fronts. If you’re worried about the weight of a glass surface, you can also use Plexiglas™ and achieve a similar effect. Backpainted Plexiglas™ is a great alternative for cabinet fronts because it is very lightweight and will not put extra stress on the hinges. You can use Plexiglas™ to quickly reface existing cabinet fronts that have worn or been damaged.

To backpaint, you’ll need glass or Plexiglas™ that’s been cut to size. If you intend to use glass near a stove, you’ll want to use tempered glass. Consult with a glass shop to be sure you get the exact size glass you need. Once glass has been tempered it can’t be cut, so you need to start with glass that’s ready to go.

Glass and Plexiglas™ require minimal surface preparation before you apply Glassprimer™ glass paint. Surface prep includes washing the surface of the glass with rubbing alcohol and lightly abrading it with fine steel wool. This will remove oils and other surface contaminants that may prevent the paint from adhering to the surface.

Dry the surface with ordinary paper towels. (Don’t use the lint-free kind; the store brand cheapies are ideal here.) That’s it! You’re ready to apply Glassprimer™ glass paint to the glass surface.

Glassprimer™ glass paint is engineered to form a permanent bond to the glass, so once the paint is cured, it won’t come off. The paint dries to the touch in a few hours, and you can recoat once the paint is dry. The easiest paint application method is spraying with a high-volume, low-pressure paint sprayer. You can find these at any home improvement store. An HVLP paint sprayer is ideal because it actually minimizes the amount of paint you need to cover a surface, while providing an even coating of paint. An HVLP paint sprayer works with any kind of paint, so you can add one to your kit and use it for any future paint project. You can also apply paint to glass or Plexiglas™ using a good quality brush or roller.

Once the paint is dry, you can flip the glass and mount it using a neutral cure silicone adhesive, also available at any home improvement store.

Glass insulation and new technologies

Glass has been used in building windows for hundreds of years. Single pane windows were the standard for most of this time, but in the quest for better energy efficiency, double-pane and triple-pane windows have been brought to the market.

Double pane windows have two sheets of glass with a single gap between them. The gap is often filled with an inert gas like argon, and tightly sealed. The gas increases the insulating value of the glass and helps reduce both energy costs and energy losses. Double-pane windows are readily available for both new construction and as replacement windows.

Under the assumption that two panes of glass are better than one, triple pane windows feature three panes of glass and two air gaps. As with double-pane windows, the gaps are filled with inert gas and tightly sealed to prevent leakage. Are triple-pane windows really better?

Triple-pane windows are heavier than their double-pane counterparts, but they’re about 20%-30% better insulators than their double-pane cousins. The weight of the window may not be of great concern, because once the window is installed, it’s weight isn’t really relevant. The added weight does increase the cost of transportation, however. The increased insulating value does have significant benefits. With regard to noise insulation, triple-pane glass doesn’t provide significantly better noise insulation that double pane glass does.

There is some industry research being conducted in Europe on the value of quadruple-pane glass windows. Quad-paned windows have four sheets of glass and three insulating spaces. Typically, the four sheets of glass have a single-sided anti-reflective coating, and the inner and outer panes are made of low-emissivity glass. These windows aren’t in production, but they’re being evaluated on a cost-benefit basis.

In addition to quadruple-pane glass windows, some research is being done on multi-pane thin glass that is vacuum sealed. The thin glass reduces the weight of the finished window, and the vacuum sealing helps improve the insulating value of the window. Building a thin-glass, vacuum sealed window is tricky, because the seals need to be robust enough to last over time. Experimental windows using vacuum-sealing haven’t proven to last very long, which makes them unlikely candidates for production.

Currently, triple-pane windows offer the best insulation properties of any window product on the market for residential applications. Glass with low-emissivity and anti-reflective coatings offers significant advantages in commercial applications.

One inexpensive option to reduce heat gain is glass paint. Glassprimer™ glass paint is designed to bond permanently with glass, and can help reduce solar heat gain, while still permitting light transmission. Glassprimer™ glass paint also offers superior UV resistance, so it won’t chip, fade or peel, even in direct sunlight.

Stained glass future in doubt

Churches around the United States are finding themselves in a new battle – one that pits their cherished stained glass artwork against the environment. Stained glass suppliers and manufacturers are being limited by federal regulations governing lead and other heavy metal emissions from glass furnaces. That makes the future of stained glass uncertain. It also means that churches will have an increasingly difficult time getting stained glass windows made, repaired and replaced.

The US Environmental Protection Agency is considering new regulations that will significantly limit the emissions from glass furnaces. Ordinary glass does not emit significant pollution, but colored glasses – many of which are made by combining metallic salts with raw materials for glass – can emit high levels of heavy metals like lead, cadmium, manganese, chromium, cobalt, copper, nickel and uranium.

While some of these metals are stable at room temperature, the glassmaking process heats the metals to the point of vaporization. Most of the vaporized metals are released into the furnace exhaust. Furnace exhaust can be filtered, but the filtration systems are extremely expensive, and beyond the budget of most glass producers.

In addition, current federal regulations provide exemptions for smaller glass furnaces, but new regulations would lower the filtration requirements. The required filtration systems would likely be too expensive for small glass furnaces. Stained glass windows are completely customized, and can exceed $20,000 apiece. The loss of smaller glass producers would likely increase the price of stained glass beyond the reach of most churches, and increase the amount of time required to fulfill stained glass orders.

One alternative to stained glass is painted glass. Painted glass windows can provide a similar effect to stained glass windows, but do not compromise the environment during production. In addition, painted glass windows are easier and less expensive to repair and maintain.

Iconic Glass Structures – Capital Gate, Abu Dhabi

Abu Dhabi is the home of a number of iconic glass structures. One of the most recognizable buildings is the Capital Gate. Built in 2010, the Capital Gate is a 35-story hotel and office complex that has a pronounced, 18° lean. The Capital Gate holds the distinction of being the world’s furthest leaning manmade tower.

The glass and steel structure is built using a pre-cambered core, which allows the building to lean without the danger of collapse. The core is built slightly off-center and anchored with nearly 500 pilings buried nearly 100 feet underground.

The building also uses a “diagrid” technique to counteract seismic forces and the effects of wind. The first 12 floors of the building are built directly on top of each other. The remaining floors are offset between .3 and 1.4 meters to achieve the building’s signature swirl shape. The building is part of the larger Abu Dhabi National Exhibition Centre, which is owned by the Abu Dhabi National Exhibitions Company.

The Capital Gate is not the tallest building in Abu Dhabi, but it is distinctive, nonetheless. The building’s lean is nearly four times that of the Leaning Tower of Pisa. It also features a “splash canopy” that helps to shield the office tower from the sun. By shielding the glass on the sunny side of the building, the splash canopy reduces energy consumption and makes the office floors more comfortable. The building is a combination of architecture and engineering, and has won numerous design awards since its opening.

The Capital Gate is home to the Hyatt Capital Gate Hotel, a 189-room luxury hotel, which occupies the upper floors of the Capital Gate building. The hotel rooms feature floor-to-ceiling windows, an outdoor lounge and spa area.It is also attached to the largest convention and exhibition venue in the Middle East.

Flat glass prices finally level out

According to the Bureau of Labor Statistics’ Producer Price Index (PPI), the price of flat glass leveled out in July, for the first time in five months. Prices increased just .1% in July and .2% in August, following months of full percentage increases. Overall, the price of flat glass has increased 8% since last year, owing in part to increased demand for glass and relative shortages in raw materials used in the production of glass. In addition, glass intended for new construction must meet higher energy and safety standards.

The construction and automotive industries account for the two largest glass consumers. Overall, demand for glass is expected to exceed $130 billion by 2020. Demand is also increasing for specialty coated glasses and photovoltaic glasses. In construction, these glasses are used to decrease energy consumption by controlling both solar heat gain and seasonal energy losses.

Increasingly, the automotive industry is turning to specialized glass to support new safety features. This increased specialization spurred Safelite, the nation’s largest auto glass manufacturer, to announce that it intends to withdraw from the auto glass manufacturing market by October. The company will still provide auto glass replacement services, but will leave manufacturing to smaller, more agile producers.

An 8% increase in the price of glass over a single year does not seem overly dramatic, but since 2008, the price of flat glass has increased 25%-50%. Flat glass prices have increased virtually every month since 2012. The long-term price increase stems from the fact that during the height of the recession, nearly one-third of the nation’s glass manufacturing plants were taken out of service, and were not replaced. The reduction in the number of producers, combined with the increase in demand, has resulted in longer lead times for production and an increases in the price of the product.

Some consumers are looking overseas for additional product, but transportation issues and lead times often make the cost of importing glass a wash.

One alternative to specialized glass may be glass paint. Glassprimer™ glass paint is specially formulated to bond permanently with glass surfaces, and provides superior UV protection. Glass paint can still permit light transmission while controlling solar heat gain, and is available for about $1 per square foot.
