STM Sapino and Sapino A
The all-timber STM Sapino and Sapino A (the triple-glazed counterpart) windows are made using only the highest quality timber. This is a classic and stylish window, suitable for renovations or new builds.
One of the main requirements is that it must be knot-free. This avoids any brown rings from knots that will eventually penetrate through the paint.
Like most traditional Scandinavian timber windows, the Sapino has a flush exterior, with only the lower drip projecting out from the frame.
To enhance the traditional Danish appearance further, casement fasteners can be chosen for a classic handle choice, interior timber can have traditional moulding and almost any decorative glazing bar arrangement can be configured.

Heartwood is naturally waterproof. It has a high content of oils and resins, which contain fungicidal substances, and absorbs only 20% moisture. Timber heartwood is a perfect material for windows and doors, as wood starts to decay at 30% moisture. 90% of the Sapino timber is made from heartwood.
All timber components are given STM’s special surface treatment. As well as introducing a unique Danish treatment oil, the timber is sanded and coated with water-based paint. STM use 20%-30% more paint than the industry requirement. Combining this with a solid frame design gives the product a long life.
All of STM’s products have a positive environmental profile and they only use green energy.
STM pride themselves on creating windows and doors to suit all environments and homes. If you have any special designs for your windows or doors, be sure to let us know!
