What is 'Easy Timber Frame' ?
Easy Timber Frame Is a unique fusion of the best forms of timber construction with the simplest methods of conventional assembly. It combines the principles of Post & Beam structures with conventional Timber Frame Panels, enhanced to deliver strong Factory Insulated Panels (FIPs).
Prefabricated in a number of standard modular widths these can be used with other selected components to simplify basic building design.
Now anyone can use these standard building elements to quickly layout a plan, establish the building framework, and assess the cost of the resulting low energy, hybrid timber frame structure.
Working to a modular 150mm grid plan, designers simply select from a range of standard width wall panels, including door and window panels, to create their floor plans.
The small design adjustments necessary to position standard width panels and locate internal walls are quite usual. They should not significantly alter external appearances or internal room layouts. However, make-up timbers can be used for minor relocations, for instance to line up with frames in alteration or extension works.
Vertical loads are spread around the building via continuous rim beams at joist and eaves levels. Sturdy corner posts support them at the ends, with panel-junctions effectively providing double wall studs for additional intermediate support.This obviates the need for lintels which are effectively moved up into the joist and ceiling zones.
Forming part of the joist and ceiling frames these rim beams do not affect elevations and can actually allow for greater width floor to ceiling openings if required, depending on engineering.
Internal and external walls are all designed to be load bearing. The OSB3 sheathing on the external walls creates racking for these and all 38x89 internal wall frames have a central row of offset noggins to stiffen the frame. They are open, with no sheathing. (We suggest you order extra lengths of 38x89 for any additional load bearing studs required by your engineer and for junctions with other walls). External corners are formed with 100x100 or 150x150 square posts to suit your walls.
Windows and Doors
Window and door openings use 150, 313, 750, 900, 1050 or 1350 deep infill panels (which can be made narrower or cut down on site) at head or base as required. No lintels are used in the frames. Instead lintels are moved into the joist or eaves zone. This enables you to create floor to ceiling openings if you wish. Add 1300mm to the opening width for lintels to ensure these span across 2 studs on either side. If required, larger panels are fitted with lifting straps for easy handling.
Wider Joist Spans for Larger Rooms
220mm deep extra-long solid timber joists (up to 12m) can be supplied. These can bare on internal walls (if these have foundations) to give up to 5.2m spans at 600 centres and 6.2m spans at 400 centres.
Cut outs for service pipes, ducts and even drainpipes can be fitted with proprietary joist plates that encircle the pipes and let you span wider, shallower, safer and cheaper than 'I'-beams or metal web joists.
70mm, 100mm, 120mm or 140mm thick insulation is factory fitted between the wall studs. 25mm or 50mm thick insulation is factory fixed to the outside of the frame, held in place by the battens fixed through to the studs themselves.
This can virtually eliminate any residual 'cold bridging' through the frame timbers, as well as improving airtightness.
Should engineering require additional wall studs to carry point loads, these can easily be inserted into the panels on site. Likewise, if internal to external wall junctions need to be solidified, additional wall studs can be added at the connections. These can be set in the external frame on site if required.
If required, OSB can be added to any internal walls to create 'wind walls' for racking resistance. Please ask about this is specified by your engineer.
Drawings & Structural Engineering Support
All panels and frames are manufactured to the same high standards and quality out of the same materials used for timber frame buildings up to three and more storeys high. However, apart from standard details no drawings or engineering calculations are included with your panels. These can only be provided and calculated for specific, individual projects.
If you need drawings for planning and building regulations we can provide your architect with details to speed and ease their design - or we can prepare these for you.
If you need structural engineering calculations for your building and you have engaged us to provide you with the structural timber frame drawings, we can produce these for you BUT we will need a full set of your building drawings showing location, sections, elevations, and roofing materials.
Prices for these services depend on the complexity of the design, so if you send us your design asking for these prices we will give you bespoke estimates for your project.
