Within the Classic range are Rosenholm in double glazed and Danrose the triple glazed variant.

  • The Rosenholm window as standard is a double glazed window with a 115mm frame depth and, for opening sashes, a slim 86mm frame width (sometimes called the sight-line). All the outward-opening casements have the traditionally-Danish flush casement style with a 45 degree angle next to the glass.

    Vrogum’s Classic range of windows are a fantastic way to upgrade a home with better window insulation while keeping a traditional look.

    Unlike most factories nowadays, Vrogum have kept their craftsman-built approach. They’re a much smaller company compared to others we work with and, walking around the factory, it feels like a very tight-knit, almost family atmosphere with all their highly-skilled workers.

    As a company, Vrogum feel strongly about the naturally fantastic properties that Nordic pine offers. It’s a material that has been the go-to options in Denmark for many years, and will continue to be the primary choice far into the future. Nordic pine is naturally well-insulating, provides a classically cosy atmosphere inside the home and, of course, is environmentally friendly when sourced from sustainable forestry.

    There’s an emphasis on producing a quality item. Not just the timber, but all fittings, ironmongery and all parts of the manufacturing process focus on creating a product that will last for as long as possible. Our installers say exactly what they think about every product they work with, and Vrogum always gets a positive response from those who can truly recognise a high-quality item.

    Vrogum uses a 3 step paint process to ensure a high quality and consistent paint coat, first a primer layer is added that will stop the growth in any fungus spores in the wood. Second a grey or white base coat (dependant on the outer colour) is added to protect the end-grain, joints and weak spots. Finally the window is puttied to remove any divots in the surface and coated in an acrylic based paint with a minimum thickness of 100µm (industry standard is 70-80).
