Andrews Dehumidification assists Sheffield school construction

The construction of a new school in Sheffield prompted one of the country’s leading infrastructural companies to get in touch with us to assist with the latter stages of completion. The contractor in charge of the building contacted us regarding a temporary heating hire arrangement which was needed to support the laying of wood flooring.

Before this process could take place, however, it was important to ensure that the temperature of the areas in which wooden panels were to be laid had been kept at 18⁰C or above for at least 48 hours. This was to ensure that air humidity was at a normal level for habitable premises but also to dry any concrete or surfaces that could have conceivably been damp or contained moisture.

To guarantee this phase of development ran smoothly from start to finish, Andrews recommended the deployment of a single FH2000 indirect fired unit. This was accompanied by several lengths of ducting to help distribute significant volumes of warm air around the areas in which work was being done. Additionally, a number of FD40 Fast Dryer dehumidification units operated simultaneously and were deployed within the target applications to ensure that any moisture present in the air was extracted.

Once temperatures had been constantly above 18⁰C for the outlined period of time, the contractors in charge installed the wooden flooring. By doing it this way, adequate precautions were taken to ensure that there was no sudden change in temperature which could later cause air humidity to rise and potentially cause the floor panels to expand further down the line.

Before beginning the project, the client made it very clear that curbing fuel costs would be preferred if possible – prompting us to set our heater up on recirculation mode. Our hired heating and drying equipment was required on site for a total of 12 weeks and was used on almost every room in the entire school – allowing all floor areas to be professionally laid without any issue at all.
