The following

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:
|
The depth of
the joist
The spacing of the joist
Continuous or simple spans
The decking / flooring material
The fixing of the decking material to the joist
The ceiling material below the joist
Level bearings
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.

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.
