Frequently Asked Questions
Q
What are double folding windows?
Double folding windows, often referred to as bi-fold windows, feature multiple hinged panels that fold smoothly back against themselves. This design allows you to open up entire walls, creating an unobstructed view and seamless transition between indoor and outdoor spaces.
Q
What are the key benefits of installing double folding windows?
The primary benefits include maximized natural ventilation, abundant sunlight, flexible configuration options, and a modern aesthetic. They are ideal for serving bars, patios, and areas where you want to connect your kitchen or living space with the outdoors.
Q
Are double folding windows energy efficient?
Yes, our double folding windows are engineered with thermal breaks, high-quality weather stripping, and double or triple glazing options. This ensures excellent insulation, helping to keep your home warm in winter and cool in summer while reducing energy costs.
Q
How secure are these folding window systems?
Security is a top priority. The windows are equipped with multi-point locking systems and heavy-duty hinges. When fully closed and locked, they offer robust resistance against forced entry and harsh weather conditions.
