Wolf Systems easi-joist system
Main benefits of the proven, quality Wolf Systems' easi-joist system include quality of performance, ease of use and design versatility.
Apartment buildings now account for 41% of the housing completions in the UK while Ireland is experiencing the same trend As a result, engineered floors is the fastest-growing sector of the engineered wood products market and the specification is growing in importance as the number of manufacturers increases and the market becomes more complex

Software helps manage timber engineering business
Wolf Systems new and unique software system, WMS, represents a major step forward in how software can help manage a timber engineering business.
Wolf Systems' easi-joist system, which was designed specifically to provide a solution to this trend, is now employed by 37% of Wolf manufacturers - a huge increase on previous years.
In essence, easi-joists are parallel cord trusses using stress graded timber cords.
These cords are plated together with a procession engineered structural component called the metal web.

Wolf get approval for easi-joist floor system
Wolf Systems, the Midlands-based timber engineering specialist, has gained Irish Agrement Board Approval for their easi-joist floor system.
Pressing the metal webs into the cords forms the easi-joist.
In a complete floor situation, this becomes the easi-joist system.
The main benefits of the proven, quality easi-joist product include quality of performance, ease of use and design versatility.
The original and most popular use for the easi-joist is as a floor joist although it can also be used in cassette form which is becoming increasingly popular as more and more prefabrication of components is being used in construction.
Ideally suited for creating flat roof solutions, easi-joist provides easy access for service runs.
It can also be designed as pitched rafters to create a roof.
The most common application here is when a high thermal efficiency value is required; the voids in the joists give greater flexibility for insulation through the whole roof.
The key to the success of the product is the manufacturers.
It is not a product which is purchased and resold; it's an engineered product that's manufactured in a customer's factory.
Manufacturing the product brings benefits to the Wolf customer.
There are no large expensive stocks in the yard for the truss manufacturer and, because the end product is manufactured to order, costly waste is reduced.
The job only uses the materials needed to complete it so if a customer needs a four-metre long joist, a four-metre long joist is made with no wastage.
An easi-joist is still a truss, just a little shorter and flatter, as well as being easier to cut, easier to set up, easier to handle and easier to deliver.
Every roof needs a floor and every floor needs a roof; Wolf has found the answer with the easi-joist system.
Because it is a custom made product, there is the opportunity to create a wide range of different depths giving great flexibility.
This range of depths allows compatibility with solid timber and other engineered joists so there's no need for expensive drawing changes.
Easi-joists are 40% lighter than equivalent solid joists which means easier handling on site and, as the joists are made to measure, there is no site wastage.
They are manufactured to exact dimensions and the wide bearing surface allows for quick setting out.
The decking can be quickly added as temporary bracing is unnecessary and the wide nailing surface makes it easy to fix to the joist.
The open web system means that there is no need to notch or drill for pipes.
Easi-joist also offers the opportunity for retro-installation of additional services with very little disruption.
In addition, a small cross-section of timber means minimal shrinkage and quieter floors and there are very few ancillary products required to complete a floor minimising the need for a great deal of on-site training.
A future development is trimmable ends for easi-joists, giving the builder flexibility to slightly alter the spans.
This will eliminate multiple set-ups for angled wall situations.
In response to increased demand, Wolf also offers an increased level of support for manufacturers; another reason for the steady growth in the system's popularity.
In addition, the two-day easi-joist training course is now well attended and support literature includes three sales brochures, a comprehensive technical guide and a Masonry and Timber Frame site guide.
