The window replacement is already being prepared. So far, mainly paint, opening type and thermal insulation have been discussed. You now also want to sensibly include burglary protection. For this, the security requirement should be clarified before the offer decision, rather than appearing as an accessory question only after installation.
Use an independent initial consultation
The Police Crime Prevention unit (Polizeiliche Kriminalprävention) points to crime prevention advisory centres that provide free and neutral advice on suitable security measures. In its information it generally recommends mechanical protection for windows and doors as well as tested burglary-resistant products. [SCHUTZ] This article does not adopt any personal risk assessment from that source nor its own interpretation of a resistance class.
Describe to the advisory service which replacement is planned and which access points to the building are involved. Advice on the entire access concept is different from merely choosing a conspicuous handle. Which measures are sensible should be explained for your specific situation.
Align the security objective with the window offer
Pass the discussed requirements on to the supplying company. Ask them to name the specific window element being offered and the intended installation in a way that can be followed. Ask what evidence the claimed property is based on. A general catalogue term should not, without attribution, replace the statement about the entire offered element.
In the fictitious example a household presents two window offers. One merely lists an additional individual component, the other describes a tested version. The owners ask for clarification of the actually promised property and the installation. They do not decide solely on the number of terms that sound secure.
Discuss normal everyday use
An intended security gain should be understood in everyday life. Have the operation and intended use explained to you. The police also point out the importance of behaviour, such as locked windows when leaving the flat and careful handling of keys. [SCHUTZ] Nevertheless, this article does not promise absolute protection.
Discuss further requirements such as ventilation, accessibility and, where applicable, necessary escape options with the responsible specialists. This article does not explain any technical combination as permissible and does not recommend independently retrofitting or altering fittings.
Link the ordered property with handover
Record in the relevant documents which version is actually ordered and which evidence belongs with it. Request the appropriate operating instructions at handover. If a product is replaced during the contract, the security requirement also belongs again in the technical examination.
The decision aid applies to Germany and does not anticipate any Austrian standard requirements. It supplements the energy-related window planning with an independent security requirement. It is not a technical acceptance, an insurance approval or a guarantee against burglary. The aim is a clear, technically coordinated order before the window replacement.
