STM Mogano – Scandinavian Oak & Mahogany Window

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

Oak and mahogany naturally contain various oils and salts, making the timber resistant to mould and rot. Our oak and mahogany windows do require occasional maintenance, but the windows will let you know when this is necessary. When the surface becomes grey and dull to look at, it is time for that 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 or mahogany product. To help create a more cohesive design, we are able to provide the 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 also be a powder-coated blown aluminium if preferred.

    A natural oak or mahogany 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 is important to consider the modern impact of the product’s life-expectancy and the ongoing care that these types of product require. Our hardwood windows should not be painted, as their long service-life has been specifically designed around regular oiling and maintaining the natural oak or mahogany appearance.

    All of STM’s products have a positive environmental profile and only use green energy.

    STM offer 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 the best in both comfort and performance.

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