A Yorkshire builder is said to have been won over to Spatial Roof from iLevel Trus Joist by its ease of construction and the ability to create extra space.
White Rose Property Services decided to trial the system, which is claimed to offer quicker and simpler ways to build attic roofs by creating an attic room as a separate floor and roof, rather than a combined unit on a site in Bradford.
By installing the floor first it means a permanent working platform for putting up the pitched roof was formed, aiding the construction.
