Timber Window Sapino

Further Details:

The all-timber STM Sapino and Sapino A (the triple glazed counterpart) windows are made using purely 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.

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; they use only “Green Energy”.
