TECHNICALEXCELLENCE

Energy efficiency. Timber engineering provides the ideal platform for introducing a highlyinsulated building envelope. For instance, a high performance timber frame specification iscapable of making a significant, cost-effective contribution towards the whole building energyperformance rating. In addition to energy savings, building in timber frame also reduces CO2.

Durability. Modern day production techniques generate a highly engineered solution.Timber retains its natural, dynamic and durable qualities, the result of detailed design andquality controlled manufacturing processes. As with all organic materials, wood requiresprotection from the elements, and a well designed and protected timber frame structure will have a service life at least equal to its masonry equivalent.

Fire aspects. When properly designed and constructed in accordance with buildingregulatory requirements, a timber frame construction presents no more of a fire risk thanother forms of construction.

Moisture resistance. By its very nature, wood is sensitive to exposure to moisture. However, with effective detailing and an attention to detailing on site, this risk is effectivelyeliminated. In the case of flooding, once waters have subsided the inundated building can be quickly reinstated. Unlike masonry structures, which may require several months’drying before internal linings are reinstated, timber framed structures regain their integritynormally within a few weeks once the damaged internal linings (plasterboard) and moisturesensitive insulation have been removed and the low level timbers allowed to dry.

During recent years, increased levels of environmental awarenesshave led to an improvement in the energy efficiency requirementsof buildings. Howarth Timber Engineered Solutions offers solutionsto meet, and often surpass, the latest legislative requirements.

Howarth Timber Engineered Solutions understands thatin an ever changing industry, where regulation,legislation and technology impact to create confusionand uncertainty, there is a need for innovation andsimplification of the construction process. As one of the first businesses to introduce engineered timberproducts into the UK, we are extremely proud of thedesign and engineering that has gone into our I beam.

The I beam is a professionally engineered composite timber productmanufactured within a quality assured process. As with all HowarthTimber Engineered Solutions’s products, the supply chain is managed toensure consistent quality and sustainability credentials. The result is thatthe frequency of naturally occurring defects, which can impair theperformance of solid timber products, is reduced.

The structural timber I beam can be produced in a range of depths andspans to suit domestic and commercial applications. As an engineeredcomposite, the beam dimensions are not restricted by the availabledimensions of natural sawn timber. The high-strength to low-weight ratio of the I beam enables larger beams to be readily transported and handled on site.

Although the I beam can be incorporated in a range of fabricatedassemblies, it is also sufficiently lightweight and can be readily cut andinstalled using conventional construction techniques, making it a highlyflexible and adaptable product.


SAVING YOU TIME & MONEYMETAL WEB BEAMS

Metal web beams combine structural softwood chordswith high strength steel webs to form a lightweight,structural beam for use in a range of floor or wallapplications. As a fully engineered solution, metal webbeams are simple to set out and install and, crucially,allow for services to run virtually unimpeded.

Metal web beams can span greater distances than solid or fabricatedtimber alternatives and, given that they provide an economic alternativeto steel or concrete beams, considerable savings can be made in the useof raw materials. The open web design makes for simpler and fasterinstallation on site, thereby reducing labour costs. The higher structuralintegrity of the beam reduces the need for additional intermediatesupports, further reducing design and overall construction costs.

The POSI beam is available in a range of depths from 202 to 421mm,offering a diverse range of structural options for the floors and walls ofdomestic and light commercial constructions. Howarth Timber EngineeredSolutions provides a comprehensive design service where we, incollaboration with the building designer, will evaluate the feasibility and subsequently develop an appropriate design solution. In recognitionof the considerable time savings that can be achieved with off-sitefabrication and assembly, Howarth Timber Engineered Solutions can also supply components ready assembled in cassette form.

Particularly useful for larger project or developments, all POSI beamproducts are location-coded and bundled specifically for plot or projectdelivery. We can provide details and guidance on load weights anddimensions for organising and managing site lifting and installation.

Now considered part of traditional constructionaltechnology, Howarth Timber Engineered Solutions hasbeen manufacturing trussed rafters for more than 30years. Engineered trussed rafters still offer the most costeffective and flexible design solution to simple andcomplex pitched roof constructions.

Howarth’s team will formulate a practical design solution based on the supplied architectural outlines or details. This can be undertaken as a singlecommissioned solution or in collaboration with the primary design team.Howarth Timber Engineered Solutions provides technical advice, designguidance and installation information for each project.

HTE offer two design options:1. Complete roof design - we undertake full design

responsibility for the complete roof which includes thedesign and supply of all structural elements, i.e. rooftrusses, infill timber, wind bracing and any associatedstructural metalwork.

2. Component only design – we undertake designresponsibility for the roof trusses and any associatedbracing.

Regardless of whichever option is selected, each project is designed for specificloading and service class in accordance with BS 5268 PT3. Howarth TimberEngineered Solutions can provide the appropriate design warranty and we areable to fully certify our supply chain in accordance with recognised industrystandards. In addition, Howarth will evaluate health and safety risks inaccordance with CDM Regulations and provide advice so that a full and accuraterisk assessment and method statement for site operations can be prepared.

Our design and production process is fully integrated. This generates thenecessary geometric profiles, the appropriate timber grade and section, and type and size of connector plate. An automated manufacturing processestablishes the truss profile by positioning within a range of jigs and presstypes, which are selected to reflect the complexity and size of the truss.Where required, timber can also be preservative treated.

All Howarth Timber Engineered Solutions trussed rafters are loaded verticallyonto a customised trailer and delivered to site at pre-arranged dates and times.Deliveries will require some form of mechanical off-loading and Howarth TimberEngineered Solutions can provide guidance on load weights and dimensions.

A TRUSTED SOLUTIONSPANDREL PANELSSpandrel panels are pre-assembled structural piecesused as separating walls or external gables, typicallysupplied as part of a structural roof package.Howarth Timber Engineered Solutions’s spandrelpanels are specifically designed and fabricated tocomplement our range of engineered products andto replace the need for conventional masonry, whichis expensive and time consuming to build in-situ. As the composition of Howarth’s spandrel panels isbased on current robust standards there is norequirement for pre-completion testing.

As with all Howarth Timber Engineered Solutions’ products, each roofstructure incorporating spandrel panels is designed in accordance withthe Robust Details certification scheme. Howarth can provide theappropriate design warranty and we are able to fully certify our supply chain in accordance with recognised industry standards.

Howarth Timber Engineered Solutions’ spandrel panels are loaded verticallyor horizontally, as size and configurations allow, onto customised trailers,and delivered to site at pre-arranged dates and times. Once on site thepanels will require some form of mechanical off-loading and must be storedvertically. Appropriate lifting and temporary support must be provided athigh level to facilitate installation, and Howarth Timber Engineered Solutionscan provide guidance on load weights and dimensions.

FORMER MILL SPANNED WITH HOWARTH’S ENGINEERED ROOF TRUSSES

Howarth Timber Engineered Solutionsmanufactured and delivered to site around90 bespoke timber trusses, each 16.7mmetres long, to span the roof void of a refurbished mill, now converted into 30 high quality apartments.

The building, known as The SpinningHouse, is widely regarded as one ofBatley’s finest former textile houses, andhas been sympathetically converted intodesirable accommodation. Howarth wasappointed to design and manufacture theroof trusses, bracing and associatedmetalwork, based on its successful trackrecord in major projects.

The inner shell of the 19th century buildingpresented many challenges to the design ofthe roof trusses. Several existing structuralsteel beams had to be accommodated inthe fit, along with an irregular layout ofinternal walls. Furthermore, the roof spacewas designed to accommodate two atticapartments and a hallway in each truss.

Specialist vehicles were hired to transportthe trusses to site, which is located in abuilt-up and highly populated area of theWest Yorkshire town.
