The RAL certification ensures the level of quality of your new windows, well in excess of the statutory CE mark requirements covering component quality, consistency, serviceability and service life. Out of the thousands of timber window manufacturers in Germany, only 40 are RAL certified - of which Richard Martin are one.

Statistics show that in Germany there is a burglary every 3.5 minutes - 80% of attempted forced entries are achieved through terrace doors and windows. It is easy to prevent this. For more than 35 years we have been producing certified anti-burglar windows and entrance doors. To ensure safety and affordability go hand in hand we have developed four safety levels, tailor-made for every single application.

Sustainability is a common theme in all areas of our company. The use of energy-saving LED technology for light sources and the use of solar energy for generating electricity are part of this. Our heating utilises wood waste from our own production facility and for our products we only use water-based varnishes and paints. We manufacture high-quality, long-life products which give hardly any disposal problems. Above all, we work with the most sustainable material of them all, timber.

The timbers from which our windows and entrance doors are manufactured originate almost entirely from FSC® or PEFC™ certified forests. You can find the certification badge on your door or window between the frame and window sash, showing that we have been certified according to the strict criteria of the two global sustainable forestry organisations. This ensures a closed product cycle: the timber for our products is accounted for from forest to finished element. Detailed timber certification and labeling also ensures that each piece can be identified throughout the entire manufacturing process.
