Living in the attic has its own unique charm – beautiful views and cosy space under sloping ceilings contributing to a special atmosphere. But to fully enjoy this place, you need to ensure adequate lighting, temperature and comfort. Roof windows with lower transom have been designed precisely to maximise the potential of the attic and provide the best conditions for the household throughout the year. This solution combines aesthetics and functionality – an additional glass in the lower section of the window lets in much more light and improves the view outside. This makes the space seem larger and more open, and contact with the surroundings becomes natural and comfortable. This group includes four models: FDU-X P50 AUMX, FDP-X P50 APMX, FDU-V P50 AUMX and FDP-V P50 APMX, which differ in terms of finish and equipment, so that everyone can choose the option that perfectly suits their needs.
Daylight is one of the most important elements affecting the comfort of living in a home. It makes rooms appear larger, brings out the colours of walls and furniture, and gives household members more energy to act. In roof windows with lower transom, an additional glass at the bottom of the structure allows sunlight to penetrate deeper, evenly illuminating the entire interior – from floor to ceiling. Imagine a morning in your bedroom when the first rays of sunlight gently stream through the window, illuminating the entire room, not just the upper part. In the living room, you can enjoy natural light until late afternoon, which gives the interior a pleasant, warm atmosphere. In the kitchen, better natural lighting means greater comfort when cooking – dishes looks more appetising and the work is less tiring for your eyes. The lower transom also improves the view outside – sitting on the sofa, at the table or even on the floor with your children, you can freely admire the garden, the sky or the city skyline. Children can observe their surroundings without climbing on chairs, which gives them a sense of independence and security.
Attics can be difficult to maintain an optimal temperature – they can easily become cold in winter and hot in summer. That is why roof windows with lower transom are designed to protect household members from these problems. Their design and special glazing units ensure that heat stays inside in winter and cool air does not get in. This makes getting up in the morning in the bedroom more pleasant, and family evenings in the living room take place at a comfortable temperature, without the need to heat the rooms. In summer, even in strong sunlight, the interior does not overheat so easily. You can fall asleep in a cool, airy room and wake up without feeling stuffy. This is especially important in south- and west-facing bedrooms, where the sun is strongest. This thermal comfort also translates into savings – less energy used for heating in winter and air conditioning in summer means real financial benefits.
Noise is one of the greatest enemies of home peace. The sound of rain hitting the roof, wind, passing cars or loud conversations outside can effectively spoil the mood. Roof windows with lower transoms effectively reduce these sounds, creating a real zone of silence inside. Imagine that during a downpour you can watch a movie in your living room in peace, with the sound of rain as a gentle background. In your child's room, even if it is a busy day outside, there is peace and quiet, conducive to play and learning. In your bedroom, you can sleep undisturbed, even if your house is located near a busy street.
Room ventilation is crucial for health and well-being. Window versions with automatic air inlets ensure that your home always has fresh air – without having to open the sash. The ventilator automatically regulates the amount of air let in depending on the conditions outside, eliminating drafts and heat loss in winter.
A window is an element that you see every day – both from the inside and outside. That is why it is so important that it matches the style of your home. In this group, you will find two types of interior finishes: white polyurethane – ideal for modern, bright spaces, moisture resistant, easy to clean. Great for bathrooms, kitchens and minimalist living rooms. Natural pine wood – adds warmth and cosiness, looks beautiful in bedrooms, living rooms and Scandinavian or classic-style interiors. On the outside, all models have modern cladding in fashionable colours – from elegant anthracite to deep black – which allows you to maintain a consistent and modern look for the entire building.
Roof windows with lower transom have been designed to make everyday use as easy as possible. The handle at the bottom of the sash makes it easy to open and close, even in the case of large windows. The micro-ventilation function allows for gentle ventilation, and a special locking bolt allows you to safely clean the glass from the inside – without going out onto the roof. Thanks to the security system, you can feel safe – the window design is resistant to break-in attempts and accidental opening. The easy-to-clean coating keeps the glass clean for longer with rain and sunlight naturally removing minor dirt.
