Reinforced construction and resistance to weathering
Steel reinforcements embedded in PVC profiles provide exceptional strength. The material withstands extreme weather conditions with ease. Thermal break aluminum doors never rust, corrode, or deform over time, maintaining their perfect shape indefinitely. The surface is completely resistant to scratches and fading. This durable construction requires minimal maintenance, saving you significantly on repair costs. Its robust design easily handles daily use, offering reliable protection while preserving its aesthetic appeal for years, even under the constant exposure to sun, rain, and temperature fluctuations.
Excellent thermal and sound insulation properties
