Märynummi School & Day Care Centre
Log school's safe and natural fire protection
Prior to this building project, the school and day-care centre for the town of Märynummi operated in several different buildings. Of the two buildings that the school had been using, one was demolished due to indoor air problems, and the second underwent a renovation. For the new building, non-settling pine logs were selected as the building material, as they are a breathable natural material well-suited to the surrounding forested environment.

RESULTS WERE ACHIEVED WITH GREAT COLLABORATION
The overall job included building an approximately 1,500 m2 modern log building on the site of the demolished school. One of the two old buildings was renovated. Architect Kristiina Krapu from the city of Salo was responsible for the design, and the project was implemented by Varpe Oy.
At this site, the reaction to fire performance requirement for indoor surfaces of log walls was to meet Euroclass C-s2, d1. The log walls were treated with Nordtreat’s clear flame retardant, which allowed them to achieve an even higher fire-class of B-s1, d0. Kontio had used Nordtreat’s products for the fire protection of log buildings in the past as well – there is no comparable product on the market that delivers the required reaction to fire performance in a way that is environmentally friendly and allows the wood's natural fibres to remain visible.
