Robust Details handbook update

With the new year comes a new update to the Robust Details Handbook. This handbook provides a reference manual for those working on the specification and building of separating walls and floors in new homes. This scheme enables compliance with Part E of the building regulations without the need for PCT (pre-completion testing) for newly built residential dwellings.

The latest changes to the handbook provides an increase in options available when using E-WS-1 and E-FS-3 as well as further guidance for users of E-WT-2.

Making use of light weight steel constructions

As part of this update Robust Details have announced that Fusion's Thermashield pre-insulated factory built panels have now been approved as a flanking option for E-WS-1. Thermashield had been included as an option to E-FS-3 in the June update which means plots can now be registered for complete wall-floor combinations using Thermashield.

E-FS-3 now allows the use of a generic 16mm resilient bar where a second ceiling is suspended underneath (giving a minimum 150mm additional void).

The final update on E-WT-2 now clarifies the situation with sheathing boards and the dimensions to be maintained when setting-out.

What's E-WT-2 used for?

E-WT-2 is primarily used when more structural sheathing is required than permitted for E-WT-1.

This latest update provides information on what can be done when structural considerations allow E-WT-2 wall leafs to be constructed with partial sheathing or no sheathing at all.

You can download the full handbook on the Robust Details website.
