Copper Cladding

Designing with copper cladding usually starts from from a known line. Architectural cladding drawings will supply the lines that are important to the architect. For example, horizontal cladding may be required to line up with the finished window size at the head and the sill. The architect will show how many panels are desired to span the window. Dividing the window frame size by the number of panels will give the panel width including any reveal.

Materials

Copper cladding is available in sheets as well as brake-formed panels. There are more traditional pure copper panels as well as copper plated on stainless steel. The latter can be a very cost effective way of gaining the look of copper while stating within tight budgets. Copper has a rich history, being used for centuries in historic churches as well as being a material that is associated with certain countries such as its use in Canadian architecture.

Erection direction

The orientation of the cladding profile is important. In hidden fastener styles of cladding the panels must be installed so that there are no voids that can trap water. Keeping the voids open to the bottom allows the wall to drain. The installation process has to be planned out on paper to make sure there are no unanticipated changes in direction brought about by site conditions. An arrow indicating erection direction can be placed on each elevation as well as a start indicator to help the installer organize the installation of panels.

Grain Direction

Many types of cladding have a grain that must lie in a specific direction, often specified by the architect. This grain direction must be carried through all the fabrication drawings right from the elevations to the work orders to the unwinding of material from the coil or from the cutting out of sheet.

Fastener Selection and Electrolytic Corrosion

Copper cladding requires matching fasteners.If copper cladding is brought in contact with another metal such as steel, electrolytic corrosion can occur. Steel fasteners for example would be eaten away. For this same reason the flashing material must also be copper. A wood substrate will be necessary to separate the copper cladding from its steel sub-girt support system. Flashing Coordination with trades is important when flashing.

Installation

The responsibility for window head, sill and jamb flashings is often divided among trades based on order of operations. For example it makes sense for the window contractor to be responsible for the sill flashing, since that flashing often has to be installed to make a starting point for window installation. The side jambs and head flashing are often the responsibility of the cladding contractor since these can be added later prior to the window being caulked and even after that has occured.

With materials like copper cladding it may be necessary for the cladding contractor to be responsible for the window sill and in that case there will have to be coordination with the window contractor. Design details must delineate the responsibility for particular flashings especially when working around windows and doors.

  • Yuuuuup - Auction Websites in Ontario !

    Perhaps its because of the hit TV series "Storage Wars" going to auctions of all types has become very popular. Both for personal and for business purchases. Visiting auctions can be a great way for a new business to get started. If you are looking for office furniture and factory equipment there are always great bargains to be had.

    Be extremely careful when computers, flat screen TV's and other technology items. You must know the value of these items before bidding. People go crazy about these items and auctioneers know it. In the heat of the moment people often pay more for a used computer that is several years old then they would brand new in a retail store.

    Bear in mind you are buying items as-is where-is and there is always the possibility that the item you are buying wont work or be damaged in some way. Take advantage of the inspection days that most auctioneers provide and factor the risks into the maximum price you are willing to pay for an item. Record this information and have it handy when the auction starts and you go to bid.

    Auctioneers often will refuse to sell an item if it does not draw a high enough price, they will withdraw the item and list it in a future auction where they hope it will gain more more attention. In general it pays to find an item you are interested at an auction where the majority of bidders are not looking for that kind of item. You want to be the only person bidding on it.

    Auctions most often charge a fee over and above what you pay for the item. This is called a “buyers premium” and usually goes to cover the cost of the auctioneers services. You have to factor in this cost. As well, You also have to pay all applicable sales taxes.

    The internet has revolutionized the auction business. Many auction houses use the services of www.bidspotter.com which allow users to view the auction live and bid online without actually being at the auction. This increases the bid frenzy dramatically and drives up profits for the auctioneers. But its great if you want to log on as a guest and get a feel for a live auction and see how the auctioneers work the audience.

    Registering with Bidspotter is simple and is no different than registering for an auction in person. The main difference is that you can bid in auctions across the continent. Just bear in mind that if you win a bid you will have to pay to arrange shipping and delivery to your location if you are unable to pick the item up your self.
