impregnation). Normally, it is easy to predict were the risk of rot will be – e.g. 95% of the rot attacks in windows are found in the bottom part of sashes and frames. Logistics Linseed oil treatment does not fit in very well in the logistics at a modern rational building site – especially not if other work is to be carried out at the same time. Long drying hours, sensitivity towards dust and mechanical influence ("friction") are some of the factors that make it difficult. The most durable of the examined treatments had been performed most carefully: after the priming the windows were treated with 5 coatings of linseed oil paint applied with an interval of one week – that is, a total duration of treatment of min. 6 weeks. Such a long duration of treatment will be hard to carry through in ordinary building, e.g. within urban renewal. Preferably, linseed oil painting should be performed in a workshop. If the treatment is to be performed on the spot, it should rather not be performed simultaneously with other work. Scaffolds mean a rise in price because of the long drying hours. Application criteria Linseed oil paint does not live up to the same application criteria as modern paints. It yellows, chalks, wrinkles up, attracts more dirt, etc. It is debatable whether it important, but not all builders are prepared for this. 10.5 Potentials Linseed oil systems Probably, it would be possible to make use of the good properties of linseed oil and still take into consideration logistics and application criteria if linseed oil was used as priming and a 'modern' paint (e.g. aqueous alkyd) as topcoat. However, it is necessary to use paint in systems to secure a product guarantee. The manufacturer will inform you of which priming and top coatings should be used together. On the “want list” for a good linseed oil system is the following: • an all round primer based on heat treated linseed oil • a primer with fungicide against dry rot for treatment of particularly exposed places • a 'modern' topcoat paint that can stick to the current different types of paint, and that dries fast These products either do not exist at all or they do not exist within the same system. 85
New windows New factory made windows treated with linseed oil exist on the market but they are not exposed to DVC-label. They are more expensive than similar windows, but this may be compensated for by its durability which eventually will result in a better over all economy – but as far as it is known, no actual documentation for durability exists. Therefore, the “want list” for new linseed oil treated windows include: • a testing (accelerated tests of ageing) of new industrially treated windows • a calculation of the over all economy compared to traditional DVClabelled windows • a system of labelling equivalent to DVC 86
