ROOF TRUSSES

At Modeco Timber Engineering we are committed to manufacturing the perfect timber roof truss for your building whatever its size or complexity. All our roof trusses are precision engineered using the latest Gangnail software application. We use high quality stress graded timbers supplied from sustainable European Forests. We are NSAI approved under Standard EN 14250.

Benefits of using timber roof trusses:

• Wooden roof trusses use 40% less timber than traditional construction methods significantly cutting your materials cost.
• As the trusses are fully manufactured off-site they can be quickly erected once delivered to site.
• Off-site manufacturing eliminates the need to store roofing timber which saves valuable space on site.
• Attic trusses provide the necessary head space for attic conversions.
• Special trusses can be used to allow for vaulted ceilings in hallways.

Attic Truss

Timber attic trusses combine the speed of erection on site of standard trusses with the open plan nature of the traditional cut roof. Attic trusses can give you several extra rooms in your house for very little extra cost in relation to project as a whole.

Attic trusses offer several major advantages:

• Roofing a house using attic trusses can be up to 5 times faster than using the cut roof method.
• Quality is guaranteed every time using attic trusses. Remember a cut roof is only as good as the carpenter/joiner’s individual skill and experience.
• Attic trusses allow for further expansion in years to come. For a little extra initial outlay, the option of one or more extra rooms in your building is there for life. Even if the attic area isn’t availed of upon moving in straight away, the space will always be there if needed later down the line.

Stubbed Attic Truss

Also known as an ‘upstand attic’, these allow for larger room widths and greater headroom over conventional attic trusses.

The end height at wall plate can be customised to suit the eaves detail you require, or to maximise the room height achievable within your attic space. With cavity wall construction the internal leaf of blockwork typically stops at ceiling level with a wallplate on top to support the ceiling joist of truss. The external leaf of blockwork then continues on up to match the end height of the truss.

Scissor Truss

The lowest cost option to provide a vaulted ceiling – with scissor trusses being around the same cost per truss as a fink or queen post truss with a flat ceiling.

Parallel Chord Truss

These are a very popular option to provide a vaulted ceiling.  Similar to a scissor truss, except the internal ceiling and the external rafter are at the same pitch.  This provides a ceiling which goes up into an apex in the centre.

Parallel chord trusses provide a more thermally efficient alternative to conventional cut roofs with steel apex beam.  Eliminating the steel from the roof construction removes the potential for it to cause thermal bridging, whilst also allowing a greater depth for insulation (typically 450-600mm+)

They are ideal for use where you have gable apex windows.
