Choosing Window Frames
There are three main types of material used to manufacture window frames.
These are aluminum, PVC-u and wood. These are also vinyl-coated and fibreglass
frames, but for simplicity at this stage we shall stick to the three main types.
The three materials each have their strengths and weaknesses and in this article
we shall look at the several properties to see how each type shapes up. The
properties we look at are heat insulation, sound insulation, security,
appearance, maintenance and least but definitely not least, cost. We shall also
briefly talk about the different styles of windows commonly available today.
Heat insulation is perhaps the most common reason for getting double-glazing.
However, if the frame is not right the insulation provided by double-glazing is
lost. The worst conductors of heat and therefore the best insulators are wood
and PVC-u. Aluminum is a relatively good conductor of heat and so is not the
best material if this is of primary concern.
The protection against sound is another great attribute of double-glazing and
their isn�t really a clear winner. The relative sound insulation properties are
therefore of lesser concern that those of say heat.
Security is always a concern and here we have a clear winner. Aluminum is
extremely strong and is the material of choice where security is of major
concern. This explains why aluminum is commonly seen on commercial premises.
Wood and PVC-u have their weak spots. PVC-u expands during hot temperatures and
the expansion gaps required can become weak points for intruders.
Another area that has a clear leader is appearance. Wooden frames are easily the
most attractive frames. The timeless appeal of wood suits both modern and period
properties. In particular, for period properties it is almost mandatory to have
traditional looking frames and in particular sash windows. The appearance of the
properties can be undermined with PVC-u frames or cheap looking fake wood
finishes.
Although wooden frames are the most pleasing on the eye they are also the
hardest work. Older frames require a significant amount of attention to prolong
their life. The newer wooden frames are treated before being shipped to
retailers but they still require the attention. Regular coats of protective
paints are needed every four or five years. PVC-u and aluminum frame require
very little maintenance and can be cleaned with just an occasional wipe with a
damp cloth.
Finally, we look at the cost of the different types of frames. Generally
speaking, the cheapest are PVC-u frames, followed by aluminum and finally wood
are the most expensive. The economic benefits of PVC-u frames combined with
their excellent insulation properties go a long way to explaining their
popularity.
There are many different styles of window that can be manufactured from the
three materials. Casement windows, tilt and turn windows and sash windows are
all made from the three materials.
