Technical SpecificationsOur easi-joists comply with all the relevant British Standards for resistance to sound, fire and deflection. Our joists have been tested for fire resistance in accordance with the requirements of BS476-21 and meet the standards for sound resistance Part E of Schedule 1 of the building regulations. They are limited to a maximum deflection limit of 14mm as to the NHBC regulations. easi-joists supplied by us are usually designed for a domestic floor load of 1500N/m2 (which is standard in the UK), unless otherwise requested. We also add an additional load of 250N/m2 for insulation and plaster board, 250N/m2 for floor boarding and 250N/m2 for partition walls. easi-joists are not designed to support block or load bearing walls. As well as being supported on wallplates as usual easi-joists have the added advantage of being able to supported on the top chord. This means that you can cut down on metalwork and can also have the floor designed to hide any steels within the floor. Below are examples of the two: Top chord support on wallplate
