STM Mogano – Scandinavian Oak Window

Look no further for high quality oak windows than the STM Mogano. Sustainably-sourced and high density (at least 550kg per m³); STM only use timber from PEFC-certified forests, and select the wood that will go into manufacture based on the colour and weight.

Oak itself has a naturally large amount of various oils and salts, making the timber resistant to mould and rot. Our oak windows do require occasional maintenance, but the windows will let you know when it’s necessary. When the surface becomes grey and dull to look at, it is time a coating of oil.

A popular request is to have the majority of windows in a home as aluminium-clad timber, and to then have the main entrance door in our oak product. To help create a more cohesive design, we are able to provide the oak door sash in a frame that will match the rest of the windows.

  • As standard, the window has a wooden lower glazing bead, but can be a powder-coated blown aluminium if you prefer.
    A natural oak product is a very traditional and classic route to follow. In the UK, many conservation areas require replacement windows and doors to be manufactured from oak. When choosing a traditional-looking product, it’s important to consider the modern impact of the product’s life-expectancy and the ongoing care that these types of product require. Our oak windows should not be painted, as their long service-life has been specifically designed around regular oiling and maintaining the natural oak appearance.
    All of STM’s products have a positive environmental profile; they use only “Green Energy”.

    As with all our bespoke windows, if you have any complex designs for your windows or doors, be sure to let us know! It’s very likely that we will be able to find a solution for you.

    STM have a complete range of windows and doors to provide a complete solution for your dream home. Their products achieve the highest levels of energy and environmental performance to ensure both comfort.
