Boise Engineered Floor Joist Flooring ConstructionBoise engineered floor systems were introduced to the U.K in 1998, but worldwide , Boise employ 23,000 people and have been selling innovative timber products since the 1950’s. In North America engineered floors constitute up to 40% of the timber floor market in some states and for the same reasons the U.K. construction industry has now identified significant advantages, offering ease of installation, house design flexibility with non load bearing walls and eliminating shrinkage and squeaky floors.

Joist Profiles


The following profiles will help designers to prepare an economic and practical scheme.
 

Boise Engineered Floor Joists Specification

BCI Joists are approved by British Board of Agr�ment - BBA Cerificate No. 99/3620.


The performance of a floor is a matter of opinion.  The "feel" that satisfied one individual may not satisfy another.  Many factors affect the performance and "feel" of a floors, these include:
   

  point.gif (857 bytes) The depth of the joist

  point.gif (857 bytes) The spacing of the joist

  point.gif (857 bytes) Continuous or simple spans

  point.gif (857 bytes) The decking / flooring material

  point.gif (857 bytes) The fixing of the decking material to the joist

  point.gif (857 bytes) The ceiling material below the joist

  point.gif (857 bytes) Level bearings

  point.gif (857 bytes) The location of walls and furniture

Increasing the stiffness of a floor system will improve its performance and "feel".  The most efficient way of increasing the stiffness of the floor is to deepen the joists - this is simple engineering fact. 

A 25% increase in joist depth will have the same effect as doubling the joist width of halving the joist centres.  A clear justification fro the "deeper is cheaper" statement that echoes around the engineered wood product industry.  Our designers can easily design the floor to performance levels above the minimum code requirements if so desired.

Residential Floor Span Table

Recommended Spans for BCI Joists when used in Residential Construction

 

The table below represents the maximum spans for a range of floor performance levels, assuming joists are either simply supported or continuous over two equal spans.
 

 

Where joists are continuous over two unequal spans, smaller maximum values will apply; intermediate between the single- and double- span values lists, depending upon the relative proportion of the spans involved.
