STM Windows – Timber and Alu-Clad Windows

 

STM Logo

Company Overview

STM is a Danish window and door manufacturer, providing premium quality timber and aluminium-clad timber windows and doors. Like many of the manufacturers we recommend, STM treat environmental concerns seriously. By using “green electricity”, they have a positive environmental profile and use only PEFC certified wood from sustainable forestry.
Their classic and stylish timber products have a slim design, and are great both new builds and renovations. Bringing the beauty of Scandinavian design to the UK, their Mogano, Sapino and Sapino A products have a flush exterior and arguably the best surface finish in their class. The timber is knot-free, and is sanded down before applying 130-140 microns of paint.
STM’s alu-clad timber windows have the same slim design, but have the benefit of almost zero maintenance. The alu-clad Tinium 2+ and Tinium 2020 come with a 10 year warranty.
Offering the complete range of configuration options, STM offer their products as a fixed frame, side hung, top guided or swing, tilt-turn and also entrance/patio doors.

In production, STM only use top quality timber, where one of the requirements is also that it must be knot-free, thus avoiding the brown rings from the knots that eventually penetrate the paint.

STM exclusively use timber that is at least 90% heartwood. Heartwood is naturally waterproof due to the high content of oils and resins, which also contain fungicidal substances. Heartwood timber is well suited for making windows and exterior doors. Our goal is for our windows and doors to suit all buildings and environments. Due to its firmness, the timber only absorbs 20% moisture. As the decay process first starts at 30% moisture, timber heartwood is extremely well-suited for production of windows and exterior doors. The Nordic pine density is between 470-500kg/m^3 and is FSC and PEFC certified.

Timber is a natural product and, like all other materials, can be degraded by wind and weather and the sun’s UV rays. Therefore the right surface treatment is of the utmost importance. All of STM’s timber components are surface treated, cf. “2ØKO”. This is environmentally friendly, and together with STM’s solid frame/frame design, it has a long life.
