Construction system
MHArctic

Component id: 1542cs02
Manufacturer: MH Arctic A. S.
Category: Construction 
Construction type: Light (Wood) 
Window: The system is certified with the MHArctic Thor vertical window (01), Sif door (02) and Baldr roof window (03). These products are currently in development and at the time of publication are in the process of being CE-marked, therefore the thermal values are preliminary. Thor and Baldr use the Multitech G spacer and polysulfide as secondary sealant. The Sif door is opaque and is constructed from timber, insulated using Baumit OPEN (0,031 W/(mK)) and Kingspan Kooltherm (0,022 W/(mK)). 
Airtightness: The MHArctic timber modules are fitted with EPDM gaskets, which ensure a Passive House level of airtightness. Windows and doors are connected to the wall with suitable airtight connection membranes or profiles. 
Illustration: MHArctic is a lightweight modular timber construction system, insulated with Knauf mineral wool (rated lambda value 0,035 W/(mK)). The modules are fastened together using steel bolts and then covered with a weathertight membrane, before being clad with a timber rainscreen and roofing materials. The system is designed to be both manufactured and erected on site, allowing for fast delivery times and a minimised shipping costs. As investigated, the construction is deemed suitable for passive houses, as both the regular U-values of the exterior components are below 0.12 W/(m²K) and the connections meet the criteria of 'thermal bridge-free'. The surface temperatures of all connections (with the exception of window connections) meet the surface temperature requirements. 
Climate zones: Cold
