FAQs
- Q: Why should I choose a timber-framed structure rather than one
built entirely of bricks and blocks?
A: Because when it is erected you will
enjoy a fully engineered structure that has been designed to properly
transmit all loads to foundations, is manufactured under controlled
conditions, can be easily insulated to comply with current thermal
regulations, clad outside to fit in with most settings and finished
inside to suit varying individual tastes. Moreover, you will be contributing
to a global effort to build in a sustainable way and in doing so
you will help to reduce carbon dioxide emissions that are so harmful
to our environment. The reasons why you should build using Timber
frame are ever-growing. Likewise, the reasons why you should not
be building entirely with masonry are increasing!
- Q: Why are the numbers of timber-framed structures built in the
UK increasing?
A: As stated above, timber frame structures are encouraged
by virtually everybody these days because they provide positive solutions
to environmental issues raised when using other so called 'traditional' materials
and building techniques. They are also easier to insulate and are
less demanding on scarce site skills. In other parts of the developed
world, timber frame is the primary method of low rise building
and has been for many years. So, in truth the UK is not a pioneer,
but is really only adopting a tried and tested method of construction
albeit that certain aspects have been adapted to suit our climate
and customs. We have seen how it is done in the States, in Canada,
in Scandinavia and elsewhere and learnt from their expertise and
in many cases their materials are used in our factory.
- Q: Are timber-framed structures more or less expensive than masonry
equivalents?
A: In truth, they are about the same, but the move toward
greater use of timber frame has more to do with the above points
than anything to do with being cheaper. As with most things, you
get what you pay for, and you will not get a Rolls Royce for a Mini
price. However, you will get valuable advice so that you can ensure
you do obtain good value for money.
- Q: Are timber-framed structures quick to build?
A: Experience has shown that many so-called building programmes suffer
from regular 'non
activity' days when any given building is waiting for the next component
to arrive or tradesman to appear. Masonry structures, in particular, are
often affected by poor weather conditions when it is too wet, too cold or
too hot to progress the work. With timber frame construction, the effects
of the latter are not usually critical to the overall programme period and
providing delivery of components is planned in advance, it is easier to pre-book
tradesmen knowing that preceding programme dates are likely to be achieved.
So, the honest answer to the question is 'given
proper contract administration, timber frame presents the opportunity to
build efficiently and effectively, and on occasions, more quickly'.
- Q: Is it true that timber-framed structures last as long as masonry
built ones?
A: As with any method of construction, it is essential that
certain operations and details are done properly. Given that a good
standard of work is achieved, there is no reason to suppose that
the life span of a timber-framed structure is any less than say masonry
or steel framed equivalents.
- Q: Will I be able to raise finance for a timber-framed building?
A: Now that this method of construction is used more and more and surveyors
and lenders see for themselves that it really does offer an alternative
to other building forms, there should be no block to finance on
the grounds of 'non-traditional
construction'.
- Q: Do timber-framed structures represent a greater fire risk than
other methods of building?
A: Building regulations stipulate that all
buildings meet prescribed levels of 'fire resistance' dependant on
use and design. Timber frame structures are not singled out as presenting
any more or less risk. Indeed, in the event of fire, timber normally
retains its structural integrity longer than many other alternative
materials. However, exposed faces of timber are usually covered with
plasterboard to provide the required fire resistance period.
- Q: Are proper foundations required for timber-framed structures?
A: Yes, they most certainly are.
When considering domestic low-rise buildings, Building Regulation
compliance and the need to avoid differential movement usually means
that there is little to choose between substructures for timber frame
buildings and masonry types. Clearly, there will be less dead load
with timber frame and that may have an effect on specialist foundation
designs (should they be required), but in general terms there will
be no appreciable difference.
- Q: Are there any limitations for timber
framed structures?
A: Generally not, but it may be necessary to 'adapt' some
existing architectural designs to suit. For example, in some instances
glulam beams and/or steel beams and columns are introduced as an
integral part of an engineered structure and sometimes cladding
detailing may be a little tricky. However, there are a few basic
ground rules that are quickly mastered and then opportunities for
all sorts of building design are open to all.
- Q: Can I extend a timber-framed structure?
A: Yes you can, usually very easily,
providing proper engineering advice is obtained beforehand. What
you can not do is to take a saw and merrily cut away timbers to
form, say, a new door or window opening. Bear in mind that the
existing timber-framed structure was specifically engineered and
you may just be cutting away a critical load-bearing member.
