Off site fabrication can allow higher quality to be achieved. As briefly mentioned above, timber is one of the most versatile materials used within the construction industry. Many types of timber are capable of withstanding harsh weather conditions and are resistant. – Shrinking and swelling of wood: Wood has a natural ability to absorb water which is also known as Hygroscopy. Timber should always be suitably treated depending on its use and exposure, and if left exposed to water rot can lead to loss of quality. Very good results can be achieved with purpose manufactured airtight racking board on the warm side of the stud, which replaces the need for a VC membrane. Read more. Recent fire tests commissioned by the Timber Frame Industry and the ITFMA showed that in general a 15mm Type A plasterboard is required to meet the Fire resistance of REI 30 for external walls (see detail). Timber shrinks, swells, twists, cracks and … If large open plan spaces are required, however, steel framing will likely be required to ensure structural stability. Our goal is to make good design available to the general public while maintaining a strong focus on the energy efficiency and sustainability of our designs. Additional fire protection can be given to the frame by the boarding used to clad it and fire stops installed to prevent spread through the cavity. Timber frame structures must include a vapour barrier between the lining of the inner wall and the insulation, to prevent vapour passing through. As long as this balance is maintained, the supply will be sustainable. The cost will, of course, depend on the scale of the project, but timber can be cheaper than a steel-framed building or masonry building, partially due to its speed of construction. Condensation is a problem which can occur in any type of structure but having to deal with it can be extremely difficult. Unlike steel and other highly used building materials timber does not corrode in salt air or heavy industrial environments. – Prone to abiotic forces: Abiotic forces of nature like Sun, Fire, water etc. Isabel is also Accredited in Conservation at Grade 3. Shrinkage and Swelling. by Joe | May 31, 2019 | Structural engineering | 0 comments. Timber is a natural material and may shrink or swell as it has the ability to absorb water. It is important to remember that no construction material is perfect, and that is why a number of different ones are often used for each project. Condensation Choosing the right material completely depends on your given project, but each building material has its own advantages and disadvantages, there are many different materials to choose from. Disadvantages: – Vulnerable to pest attacks: Timber is vulnerable to biotic forces like termites, woodworm or wood ants. Timber can be great for insulation on buildings, whether that is sound or heat. A prefabricated timber frame can be erected on site faster than a comparable brick and block construction. However, timber frames may require additional time for their design and fabrication, which can lead to a longer wait before work begins on site. It is the connections between columns and girders that are the most vulnerable. If you require a structural engineer in Cornwall or just some advice on your building project, here at Martin Perry Associates, we provide a range of services from surveying to party wall services. Their low thermal mass allows spaces enclosed by timber frames to heat up more quickly than masonry construction, however they will also tend to cool more quickly.

It is also important to know that timber is a renewable resource making it incredibly eco-friendly. Designed by Elegant Themes | Powered by WordPress. However, timber will always be widely used throughout the construction industry, as one of its biggest advantages is that it is a natural resource, making it readily available and very economically. Reduced site labour. Timber frame structures may not achieve the same level of sound insulation as concrete or masonry as they are not as dense. She is a registered member of both the Royal Institute of the Architects of Ireland (RIAI) and the Portuguese Association of Architects. Con: Cost As opposed to light frame construction, building a post and beam home requires large pieces of high quality timber cut from large trees. This proves that timber will always be a staple in the construction industry, but with any building material, it does have its advantages and disadvantages which we have taken a look at below. Disadvantages. Speed of construction. If you have any questions, then please do not hesitate to get in touch on 01579 345777. Ideally, the racking layer should be on the warm side of the insulation, but this is not favoured by Irish timber frame erectors. If this happens to a structure which has a timber frame, it can rot the skeleton of the building. Isabel Barros Architects - Wexford is driven by a passion for creating high quality contemporary Architecture. If by any chance a fire breaks out, a timber-framed house will not be able to withstand the heat and flames in the same way a brick or steel structure would. Timber is a natural material and may shrink or swell as it has the ability to absorb water. While the frame is generally built on site, some elements can be prefabricated allowing for greater control of details and less time in construction.
