What is a Conservatory?

Filed under: General — Tags: , — Alan @ 12:23 pm

Defined as a room made of windows, differing from a room – such as a sunroom or sun porch, whether it be manufactured or stick built – with windows in it, a properly designed and built conservatory is not comprised of mass manufactured windows but instead is created from individual glass panels, or “windows” if you will, that can be fashioned from a myriad array of available glass with widely varying characteristics.

Confused by claims touting a particular brand or type of glass as better or best, people often ask Tanglewood what glass we use in our conservatories, or which is the best type of glass to use in a conservatory. The answer is both simple and complex. The glass we use is the glass that will produce the results that you desire, and the best glass is the glass that will best achieve those desired results. There is no one size fits all, with the only constant being that all of the windows and doors made at Tanglewood for our discerning clienteles’ one-of-a-kind conservatories is Argon gas filled to precise tolerances to ensure maximum insulating capability; all roof glass and door glass, and windows with glass closer to the floor than eighteen inches, is tempered as per the International Building Code (IBC).

If you plan to set up your easel and paint in your conservatory, you will appreciate the features of a soft coated glass that reduces glare while minimizing distortion of the natural daylight color spectrum. Those of you whose homes are located where intense light and heat rise to the extreme ranges will want to seriously consider heat mirror glass—especially on the roof –to make climate control of your conservatory more manageable. If you reside in a heavily wooded area populated with large trees, laminated glass affords enhanced safety and protection from the potential intrusion of heavy limbs.
You’ll be most pleased if you are among the many that enjoy specimen plants with the specialty glasses featuring properties that reduce the potential of foliage burn while providing optimum light transmission for growth and maintenance. And yes, we’ll even design leaded and stained glass windows just for your conservatory in any style, period or motif that pleases you, whether it is grandly spectacular, light heartedly whimsical, or incorporates an element of nature.

We’ve mentioned just a few circumstances necessitating specific types of glass to meet individual needs. Most clients’ requirements are not characterized by such exacting criteria, and can readily be accommodated with one of the many glasses produced in a selection of grey, bronze or green tint levels from nearly invisible in intensity to heavily shaded.

Today’s selection of high performance glass makes it possible for us to design your Tanglewood conservatory with your comfort and perspective as our principal consideration. This is why we say that the best glass is the glass that’s best for you. All glass is made from the same basic ingredients and comes into being in essentially the same way. How it is heated, treated and otherwise enhanced makes it distinctive and defines its suitability for your individual application. Tanglewood is not affiliated or aligned with a single glass manufacturer, so our only commitment is to you, not to a glass manufacturing company or brand.

Orchids. The essence of elegance for your exquisite conservatory.

Filed under: General — Tags: — Alan @ 1:22 pm

An orchid is to your conservatory what your conservatory is to your home. The crowning jewel. Everyone admires the exquisite jewel-like beauty of color and form manifest in hundreds of orchid species, but many of you are reluctant to grow them because you’ve heard that it is difficult to do so. Fear not.

Successful orchid cultivation is simply a matter of understanding which species are best suited to the environment you are able to offer them. We have a friend who claims they thrive on neglect. He has no dedicated heat source in his conservatory, and more than one hundred orchids rely on whatever heat transfers from the open interior wall window and door. At times, on a cold Pennsylvania night the temperature inside dips to the 40’s, yet he’s presented with a seemingly endless array of blooms. He waters at regular intervals and feeds occasionally. Nature does the rest. Though we don’t necessarily advise you to try this method, it seems that the orchids receive the light and warmth they need from this south-facing room during the day and the very cool nighttime temperatures mimic the contrast that orchids enjoy in some of their native high mountain habitats.

Having a conservatory gives you a leading edge in providing the two most important criteria for growing orchids. Light and Temperature. Few plants other than cacti thrive in direct sunlight, but orchids do vary in their light intensity requirements. Brassavola, Cattleya, Cymbidium, Dendrobium, Laelia. Oncidium, Phragmipedium, and Vandas name a few that can be successfully grown by the beginner in medium to high lighting, with temperatures spanning 55 at the low end to an ideal high of 70–conditions typically available in the conservatory.

Humidity and air circulation are also factors to be considered, but are most critical only in the immediate area in which the plants are displayed. Often the necessary humidity levels can be created by the use of one of several styles of water trays. Be careful to make sure that the pot is not sitting directly in the water. Orchids dislike having wet, soggy “feet”.

Contrary to what you may have assumed, you do not need to turn your conservatory into a sauna. Orchids grow best in 40-70% humidity—a huge range that is usually achievable, but in part will depend on the climate in which you live, and the conservatory heating and cooling (HVAC) system designed for your comfort as well as that of the orchids.

Common HVAC Mistakes Made When Designing Indoor Swimming Pool Enclosures and Conservatories

Common HVAC Mistakes Made When Designing Indoor Swimming Pool Enclosures and Conservatories.

Here are some common issues that need to be carefully planned for when building a swimming pool that will be enclosed within a conservatory.

1. Don’t try to control the room environment without a dehumidification system. One of the biggest misconceptions is that exhaust fans and make-up air systems can be used to maintain a proper level of humidity inside the room. Fluctuations in outdoor temperature conditions and humidity levels make this nearly impossible. Also, the wintertime cost of operating a ventilation-only system will be far higher than a system with HVAC.

2. The dehumidification system must be properly sized. This includes the two different aspects of the system – a) the capacity of the equipment itself and, b) the air turnover rate. Adequate air movement is essential to maintaining the conservatory structure (wood, steel etc.) and finish over time.

3. Installation of the proper ductwork. The ductwork in a conservatory pool enclosure is somewhat like the arteries in our bodies with the HVAC equipment itself being the heart. No matter how “good” the heart is, if the arteries are “bad”, the conservatory building will be “unhealthy”. The ductwork will usually be larger than expected, so it is important to plan for it in the conservatory design concept phase.

4. Don’t try to use the swimming pool itself to heat the pool enclosure. This is impossible to do as there will be no way to control the humidity level which will be a very big problem especially in the winter.

5. Don’t try to “overbuild” the conservatory pool enclosure using moisture resistant materials in an effort to avoid having to deal with the humidity control issues. A well designed HVAC system will control the environment to the degree that conventional materials can be used.

6. HVAC systems using more than 5 rows of evaporator coils do not remove any more moisture and are very difficult to clean.

7. The company that is to provide the system should stand behind their work; the design of the system, the components and the installation work. Some companies will offer a money-back guarantee on the system’s performance. It should state that if the design details and ductwork design are followed, the pool temperature and the room temperatures maintained at the recommended levels, the system will perform as specified. Humidity levels should never exceed fifty to sixty percent.

8. Make sure that you allow enough space for the mechanical equipment. Frequently the mechanical spaces are the last to be considered in the design process since they are not “living” spaces. If enough space is not allocated, the equipment can be hard to install and service later on.

9. There must be adequate air flow on the surfaces of the roof glass. It’s easy to think that because warm air generally rises, the roof of the conservatory will be warmed, but the nooks and angles of the roof will also trap humidity and moisture which will condense, drip and eventually deteriorate the structure.

10. Make sure that any unconditioned enclosed spaces adjacent to the main conservatory space such as dropped ceilings, soffits etc. are well conditioned and ventilated as moisture will easily find its way into all these areas, condense on building structure and damage the conservatory building.

continued cool new conservatory projects

Continued…

Not long ago while working with a client on another very unusual greenhouse project (which I will get to later), the client asked Nancy and I if we had ever built one like it before that he could go see. His project was for a large greenhouse near Boston that utilized the look and glazing techniques of the historic Conservatory of Flowers in Golden Gate Park, San Francisco.

He wanted to make sure – that as he put it, he wasn’t going to be the “guinea pig” for our latest new “great” idea – that the system we were proposing would actually work.

My answer was only that doing the unusual, even if it means inventing entire new systems is something which we do all the time at Tanglewood, and in this sense, we had done what we were doing for him many, many times before – even if we had never designed and built a conservatory anything like the one we had designed for him. Totally unique, which of course was what he really wanted, he just had to feel comfortable with the idea, which he then did – sort of!

Later on, as his project progressed, he and his builder made several trips to Tanglewood to see his conservatory being “born”. It was great for us to watch his entire attitude change as he began to see with his own eyes and then understand what goes into each of our projects and how his was such a perfect fit for him even in ways he never understood before. (I’ll get some pictures of this amazing conservatory project up as soon as I can).

Right now for example, we are designing and building two unique projects at Tanglewood. One is a small conservatory for customer in Montana that is completely clad with copper on the exterior and is beautiful stained mahogany on the inside. The roof, the casement windows, the doors and even all the exterior ornamentation (pilasters with Corinthian capitals) are being made out of copper, a Tanglewood first.

The other conservatory is an ornamental “old world” pool enclosure for a job in Mississippi that is completely constructed out of steel and aluminum. Steel windows, steel doors, decorative steel roof members and ornamental aluminum trim inside and out, another Tanglewood first. (Photos of these will be coming soon also.)

Mehmet, my counterpart in the design process, as well as many others here at Tanglewood constantly resist attempts to rehash old design ideas, even if for economy sake, some reuse is called for.

My goal is not to engage in this very difficult design and building approach just for the sake of being different, but be able to bring a very high level of creativity, inventiveness and sensitivity to bear on each project that Tanglewood designs and builds, whether large or small, expensive or not. In that way, the end result will be a completely unique yet logical and appropriate response to each of our clients individual needs.

When people look at one of our finished conservatory projects, they usually see the wood, glass and steel building that has appeared, but it is only the final result of our efforts. What is more difficult to portray is the creative process that has lead to that result and how appropriate a response it is for that particular client.

More on all this later…
