Frequently Asked Questions
Everything you want to know about our products and services.
What is the lifespan of PVC windows?
Rande PVC windows are manufactured using high-quality raw materials and advanced production technologies. With proper installation and regular maintenance, your windows can easily last beyond 30 years. Our UV-protected profiles resist color fading and deformation, helping them maintain their like-new appearance for many years.
Why does condensation occur on windows and how can it be prevented?
Condensation usually results from the temperature difference between indoors and outdoors combined with high indoor humidity. Rande’s insulated double- and triple-glazed units reduce surface cooling on the glass, minimizing condensation. Regular ventilation to balance indoor humidity is also effective in preventing fogging.
How secure are Rande steel doors?
Security is our top priority. Rande steel doors feature reinforced steel bodies, monoblock locking systems, and burglary-resistant hinges. Our doors are tested and certified in accordance with international security standards, so you can enjoy peace of mind at home with your loved ones.
