Wind and Weathertight – Mostly!

As autumn approaches, wherever possible the focus is getting the buildings closed-up before the winter weather. So in the Sports hall the composite panels are installed, the windows are installed in the historic buildings and new blocks, and wherever possible the AVCL and proper temporary drainage is installed on the new and existing roofs.

On the new blocks the frames for the windows are mounted on the outside of the wall sheathing, on an insulated bearer plate, and completely sealed to it, so that the thermal line of the windows is within the wall insulation zone, there are no cold bridges, and the air-tightness line is maintained.

In C station the spaces within the former Power Hall are well advanced; with the internal insulation boards installed and awaiting their fermacell finish boards, the partitions that define the spaces can be completed as soon as the major elements of air handling plant have been installed. This is the future Dining Hall, from the new mezzanine.

The openings under the central windows were made in the façade when the back-up engines were installed in the 1960’s. Our proposals retain them, restoring the windows above, so become the doors from the Dining hall to the external dining terrace along the Power Hall west elevation.

Following on following the works to complete the new top floor envelope, each level of the Transmission Hall starts being insulated. This view of the future activity studio at the base of the building shows the parge coat completed and the insulation boards installed to the base of the walls,  and the two types of insulation boards are stacked in the middle of the room.

The insulated wall lining follows the complex profile of the old Coil Room walls, maintaining the visibility of the relieving arches and piers of the original space. Everything is carefully sealed and taped by DCL according to the Pavatex details, including each steelwork penetration and its thermal break pad.

The stair tower frames for the lower stairs are also erected and their walls sheathed, allowing use of both for access to the upper levels.
