Energy efficiency
Windows made with REHAU PVC profiles and Reynaers aluminum profiles with thermal break are designed for excellent energy efficiency. REHAU profiles offer natural insulation through their multi-chamber design, while Reynaers aluminum systems use advanced technology to minimize heat loss. Both profile types help maintain a stable indoor temperature and reduce energy consumption, contributing to cost savings and environmental protection.
Thermal insulation
REHAU PVC profiles with up to five or six chambers and thermally broken aluminum profiles from Reynaers provide effective protection against the cold. Whether it’s a 70 mm PVC system or insulated aluminum joinery, both materials shield against noise, drafts, and moisture. These solutions help create a comfortable indoor climate even during the colder months, keeping out dust and maintaining a pleasant temperature.
Hacking protection
Both REHAU PVC and reinforced Reynaers aluminum profiles offer strong protection against break-ins. Their robust structures, combined with internal reinforcements and high-quality hardware, make forced entry difficult. Proper installation plays a key role in the overall security of the system, ensuring peace of mind and reliable protection for your home or business.
