Architectural glass is glass used as a structural element, as opposed to merely decorative or inserted in hole in the wall for the sole purpose of providing light and a way to see out. Thus architectural glass doors are doors wherein the glass is an integral structural element of the door. There are many options when choosing glass for your architectural glass doors, although it may be wise to choose from safety glass types, which include toughened, reinforced and laminated glasses. Crown glass is the earliest style of glass window. It consisted of hot blown glass forced onto a round, flat sheet and cut to size. It was a very expensive mode of manufacture and could not be used to make large panes. It is not ideal for architectural glass applications, as it is not particularly strong compared to newer glass technologies. Also, it is expensive. It is still used for restoring old buildings, however, as it has a unique look that cannot be obtained through any other process. Glass blocks or glass bricks are often used as architectural glass in building walls and partitions, but aren’t ideal for doors as they tend to be very thick and very heavy. They could be used for doors, but this application is rare. To make rolled plate glass, large ladlefuls of molten glass are thrown on the cast iron bed of a rolling table, and rolled like dough. It is then trimmed roughly while hot and soft. Figure rolled glass results when the plate is cast between two rollers, one of which carries a pattern. The resulting pattern will appear in high relief. It is usually whiter than clear glasses and can be laminated or toughened to produce a safety glass suitable for architectural glass doors. This may be an option if you want to combine strength with decorative properties, and a whiter, more opaque color for the sake of privacy. 90 percent of the world’s flat glass is float glass. Molten glass is poured onto one end of a molten tin bath. The glass floats on the tin, and levels out as it spreads along the bath. The result is that the glass will be smooth on both sides. The glass cools slowly and solidifies as it travels over the molten tin. A very small amount of tin becomes embedded on the side facing the tin, and this side is easier to make into a mirror. Molten glass floating on tin will normally spread out to a thickness of about 6mm. It is made thinner by stretching it as it cools, and thicker by squashing it as it cools. Laminated glass is a safety glass that holds together when shattered. It is held in place by a layer wedged between layers of glass that prevents the glass from breaking into large, sharp dangerous pieces. It is often used in architectural applications. As an added bonus, it insulates better aginast sound and blocks 99 percent of ultraviolet light. When choosing glass for architectural glass doors, there are many viable options, but strongly consider laminated glass for its safety features.

December 20th, 2009Architectural Lighting Design
December 15th, 2009To stay on top of today’s increasingly regulated and competitive marketplace of architectural lighting design, you must focus on service beyond customer service. This may sound like an odd thing to say if you are a contractor who takes pride in exceeding client expectations and relies on customer service to win bids. Hear us out for a moment and consider this point of view as well: your service alone to the client will end when the system is finished, and the client will probably hope that you will not have to return with a labor invoice for additional service fees for maintenance and replacements. The type of service they are looking for comes not so much from you (although courtesy and professionalism are always a given in business), but rather equipment and solutions that serve them every evening when the doors close and the lights come on. A system developed along these principles of architectural lighting design is something of an intuitive beast that anticipates expectations on two levels. On one level, it reliably performs without mishap on a consistent basis in accordance with how it is intended to perform. On an entirely different level, superior architectural lighting design anticipates increasingly strict government regulations that increasingly mandate more green technology both in terms of power costs and material builds associated with equipment manufacture. To be a leader in architectural lighting design, you have to think ahead, and you have to install equipment that in spite of its lack of “thinking” ability, behaves as though it can think and satisfies both the client and surrounding community with performance above and beyond what is generally expected. To create this level of excellence, you must take either take extraordinary measures to design an architectural lighting system or work with an exceptional vendor who can offer you some unique and very proprietary support services. Architectural lighting design on the scale that we are talking about requires investing in very expensive software that many smaller companies and freelance contractors simply cannot afford, but desperately require nonetheless to develop site lighting and exterior lighting proposals that simultaneously speak to cost consciousness, governing authorities, employee morale, branding and advertising, and power conservation. Without tools such as this to work out all the math and angles of incidence necessary to determine wattage, voltage, foot candle densities, required LPW, and CRI index, finding the right industrial lighting fixtures for the system at a price your clients can afford and still make you a profit can be like searching for a needle in a haystack in today’s online marketplace of foreign manufactured goods, inflated promises, and endless discount offers on shortcut engineering that costs more money in the long run that it saves in the short term. Consider instead the benefits of working with a vendor like us who has already spent the money on architectural lighting design software so you won’t have to, and who will offer its full functionality to any client at no additional costs to the price of the equipment you buy. If you are a small, privately owned business, you can now compete with large architectural firms and lighting designer powerhouses that previously outcompeted because they had access to resources you lacked. If you are a larger company considering purchasing a suite of programs that will then requiring expanding your staff in a time of cutbacks and recession, don’t. Let our staff assist you with the process of turning conceptual, intuitive architectural lighting design into a scientific, mathematically sound schematic of the actual hardware to be used and the recommended positions of every fixture and lamp in the system. Not only will such a partnership save you time by streamlining the proposal development process, but it will also make your line items more precisely targeted toward the long term objectives of energy code compliance, reduced maintenance and replacement costs, light pollution control, and optimal aesthetic compliments that any client can justifiably and reasonably expect from their investment in architectural lights. When all of these variables are correctly factored into the lighting design equation, the outcome promises reliable service, a compliment to operations and aesthetics, and multiple sources of ROI ranging from savings on power bills to an increase in business resulting from a safer work environment and a more attractive face to the business world.
