Procheck® 500 - BAS Signy Cummins Hut

High-performance products from the A. Proctor Group, experts at solving condensation, airtightness and energy efficiency problems in buildings have been selected for use in the construction of a British Antarctic Survey building.

The BAS Signy Cummins Hut is designed to provide a fully fabricated, fit for purpose hut, which can be easily erected to provide short-term accommodation for two British Antarctic Survey operatives to carry out incredibly valuable research in extreme polar conditions.

Main Contractor, Mike Robinson of Rothwell Robinson, Manchester explained. “Due to the extreme conditions, we wanted to ensure that only the highest performing products were used on the project. In light of the extreme temperatures involved, we approached the A. Proctor Group who carried out a full condensation risk analysis.

“Following the risk analysis, the recommendations adopted included Roofshield® for the roof and Procheck® 500 as a VCL for the walls.”

“Another key factor was that the chosen components needed to be lightweight to be carried from the shore to their final location on the island.”

Roofshield is an air and vapour permeable, highly water-resistant roofing underlay that has been made to the same high specification for over 20 years. The products reliable performance has been demonstrated in the toughest locations around the world. Its characteristics allow even very complex pitched roofs to breathe, without the need for air gaps or secondary venting.

Many vapour and air permeable underlays use an airtight VP film layer to achieve their performance, whilst Roofshield’s patented SMS (Spunbond Meltblown Spunbond) structure allows high levels of airflow, in addition to the transport of moisture vapour, making the formation of condensation in the roof space virtually impossible. It has an extremely high degree of vapour permeability, as well as air permeability, so will still perform in conditions in which air tight alternatives will not.

Procheck 500 is a strong reinforced polyethylene vapour control layer, for use within roof and wall constructions to prevent warm, moist air escaping from inside the building and condensing within the insulation. The woven extruded polypropylene multifilament scrim reinforcement provides exceptional tear resistance and robustness to withstand the toughest conditions.
