如何更换旧的铝百叶窗

较旧的铝百叶窗经常在铰链处折断

I recently had to replace three sets of 铝 窗口 百叶窗 because the original 1960’s rivets in the hinge had finally broken. Initially, I thought of replacing the rivet by drilling out the old one, but the amount of force on the hinge would probably be too much for a standard rivet. It’s much easier to just buy replacement cooper 百叶窗 from one of the major hardware stores.

我用了 Ullrich Aluminium的Trimline天窗 that I bought from Bunnings for about $30 a pair. They also offer another option called Blade Lok which secure the glass in the holders but these are more troublesome if replacing 百叶窗, as they take up more width due to the plastic locking strip. For most old 百叶窗, this will mean cutting an extra few mm off the glass to fit. If your 窗口s are on the second story like mine are, you’re probably not too concerned about securing the glass permanently.

不论使用哪种品牌,请检查玻璃的间距,以确保旧窗格适合。

卸下旧百叶窗

First, remove the glass. Trying to do anything else first is just asking for trouble! The old 百叶窗 will probably have a thin piece of 铝 bent over the end of the glass pane to hold it in place. You should be able to bend this back by hand or you can use a pair of pliers. This will allow the glass to slide out easily. Be wary of splinters from the old glass but I don’t suggest using gloves without non-slip grips as the whole pane is more likely to slip out of your hands.

Once you’re removed the glass, you’ll find the mullion (the upright bit that screws onto the 窗口 frame) is attached to the frame with screws. These may well be seized-up, so grab your screwdriver and placing it on the screw, give it a short, sharp tap wth your hammer. This should loosen the screw. If pieces of broken plastic tinkle to the floor from your screwdriver handle, go buy a better quality one!

After removing the screws, don’t assume that the mullion will come directly off the frame. It could well be stuck with paint and may also be set into a routered groove. In my case, the mullion had to be tapped outward. If you need to use a hammer to remove the mullions, use it lightly and watch for splitting in the timber frame around any groove. If this is a problem, a clamp could be used to prevent splitting.

准备窗框

准备窗框Depending on the type of 百叶窗 you’re replacing, preparation may include priming and painting the timber 窗口 frames to cover areas that were hidden by the old 百叶窗 but aren’t covered by the new ones.

The new mullions are unlikely to have exactly the same profile as the old ones, so there may be some exposed, unpainted timber. Before painting this, put the new mullions in place, check for fit and drill screw holes. When checking for fit, pay attention to the spacing when the glass holders are in the closed position. Too tight and the glass will break. Too loose and you’ll get drafts.

When you’re sure the fit is right, start preparing the frame. First, using a damp cloth, remove any grime or your paint won’t stick.  The old mullions will likely have a paint edge that needs to be sanded down to avoid an unsightly, lumpy line. When you’ve smoothed that down, put on some primer undercoat. Once this is dry, you need a couple of top coats to match the old paint. Lightly sand with fine sandpaper between coats to get the best finish. It’s not a good idea to try and do this after fitting because the locking handle and hinge makes it difficult to paint.

安装百叶窗

新型铝百叶窗Like most DIY jobs, the preparation is the time-consuming part! Once the paint is dry, all you need to do is position the mullions and screw them to the frame using the pre-drilled holes from earlier. Then, all you need to do is slide the glass panes back in and check the fit is right when the 百叶窗 are closed.

If the glass is a tight fit, you can use the heel of your hand or the rubber handle of a hammer to gently tap the pane into place. Be sure to keep it straight so that it doesn’t jam.

This is where your preparation proves it’s worth. If you rushed and drilled the holes in the wrong place, it can be very difficult to shift the mullion slightly and re-drill. It may be easier to drill new holes through the mullion instead. Just remember to punch the 铝 to create a recess for the screw-head.
