meka-leikkaus2014Fixed wood-aluminium windows are structurally wood, but exterior parts have aluminium profile casings. MEKA windows are glazed from the inside so glass can easily be replaced if needed because it can be done from inside the room. For example in stone houses, exterior plaster and jambs are not damaged if for some reason glass has to be replaced. A special feature of the MEKA window type is that the fixed and openable portions can be placed in the same frame
