Further Details:

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.

As standard, the window has a wooden lower glazing bead, but can be a powder-coated blown aluminium if you prefer.

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.
