Build Center has won a contract to become sole I-joist supplier to national housebuilder Barratt.

The merchant, part of Wolseley UK, will supply Barratt with Finnforest UK‘s Finnjoist system from this month as part of a national roll-out expected to be completed by the end of the year.

Barratt has been buying solid timber joists from Build Center in some areas but changes to Part E (Resistance to the Passage of Sound) of the Building Regulations forced it to update its flooring details.

Build Center said the 220mm Finnjoist removes the possible need for additional brick courses which may have been required in Barratt homes if a 240mm joist was used. It also works without an acoustic blanket to satisfy Part E requirements.
