Tested security for maximum burglary resistance
Burglar protection is particularly important for lift and slide systems, as unsecured windows and doors make it easier for unwanted guests to gain access. That is why we equip our lift and slide elements with high-quality security-relevant components. Our timber and PVC systems are tested to EN 1627–1630 RC2, and for timber even up to RC3. In addition, all Gretsch-Unitas lift and slide fittings are certified according to DIN 18104-2 for burglar-resistant retrofit products – for both timber and PVC systems.

Modern lift and slide elements are energy-efficient and airtight, which makes air exchange more difficult. Instead of risky shock ventilation, the exclusive slot ventilation from Gretsch-Unitas ensures fresh air while maintaining a high level of burglary protection. Even in the ventilation position, your door remains securely locked and meets the RC2 test.
