Outdated and draughty windows can become real energy guzzlers because glass panes that are not thermally insulted and leaky frames are unable to keep the heat in rooms. This results in higher heating costs and can also cause damage due to damp. This is why building owners and architects use multi-panel insulating glass for their new buildings and renovation projects because it reduces energy costs thanks to its thermal insulation, provides noise insulation and can also protect against burglaries if laminated safety glass is used. If you select multi-panel insulating glass certified with the RAL Quality Mark, you can rely on the long-term quality of the product. The surrounding frame remains sealed and the glass will retain its insulation and security properties, which means that the windows can help you save energy in your own home.
