Impact of EC5 Standards on Floor Joists and Attic Trusses

Impact of EC5 Standards on Floor Joists and Attic Trusses

Under current EC5 standards, Deflection Limits are based on product capability, replacing the British Standards, where fixed limits applied to floor joists and attic trusses.

This gives us the flexibility to help our customer improve the client experience of their house-buyers, and reduce aftercare costs by engineering issues out pre-production.

Tailored Solutions

Without customer input, our Design Office now designs to the maximum Deflection Limits of the product, with relevant details included in the quote you receive.

However, value engineering is at the centre of our operation, and we work with our customers individually to understand how far they want their floors to deflect, then tailor their design accordingly.

EC5 standards

Using reduced centres and larger section sizes where appropriate, our designers are able to design solutions within EC5 that produce the quality of floors your clients want.

Quality vs Cost

So while choosing to be limited only by the Deflection Limits of the product can result in the lowest joist costs, where quality of the houses you build matters, setting smaller Deflection Limits can make the floors you construct sturdier and reduce the noise caused by friction between sole plates.

Weighing up the quality vs cost equation is not just as simple as looking at product costs; client satisfaction and aftercare costs need to be considered too.

A house-buyer who can walk around upstairs in their new home without being heard downstairs is likely to be a happier customer, more likely to recommend you and even repeat purchase for their next move. And, of course, less likely to call repeatedly on your aftercare team to resolve those noisy floors.
