Advantages of flat roofs: Why choose a flat roof and how to light it?
House blocks topped with a modern flat roof are taking designers and investors by storm, increasingly daring to complement and diversify the landscape of traditional construction. Such a solution is not only an excellent way of distinguishing a building from the usual pitched roofs, but also offers a whole range of added values. What do we gain by investing in a flat roof?
An investment that pays off: energy efficiency and photovoltaics
Building regulations clearly define the requirements to which buildings should conform. The overriding design objective today is reducing energy losses, which reduces the amount of heat required to heat a building. The investment in energy-efficient construction is implicitly intended to bring a return in the form of lower bills.
The construction of the roof is of considerable importance in this case. When thinking about the roof slope in the context of the new technical requirements, it is important to remember the golden rule: the simpler the roof construction, the better the energy balance of the entire building.
Going one step further and making your house part of the eco-building trend, a flat roof gives you much more flexibility when installing solar collectors and photovoltaic panels.
On a pitched roof, optimal installation is usually only possible on the south-facing slope.
The flat roof gives you complete freedom to adjust the angle and direction of the panels.
It is estimated that appropriately selected solar installations can save around 60% of the energy required to heat domestic hot water and around 30% of the energy required to heat the building each year.
Dinner under the stars, relaxation in the sun - the functionality of a roof
The charm of a flat roof lies in its spatial possibilities. The charm of a flat roof lies in its spatial possibilities. By choosing such a construction, we gain additional usable space, which, if appropriately arranged, will turn into a favourite place for relaxation.
**How can a flat roof be used?
Green roof (garden): Sky green pleases the eye and the wallet. It provides an excellent insulating layer (prevents heat escape in winter, protects against heat in summer), acts as an acoustic barrier, purifies the air and retains rainwater.
Lounge terrace: We can easily turn the soffit into an outdoor dining area, ideal for Sunday lunches or romantic dinners under the stars.
Spa area: With the right budget and imagination, a home wellness area with a jacuzzi can be created on the roof.
The arrangement of a flat roof should be thought of as early as the design stage of the house. This will allow you to create additional space and expand the house vertically without any problems.
Benefits for the interior - optimum illumination through OKPOL windows
The ceiling has a huge impact on the design of the interiors beneath it. Deeper rooms often suffer from a lack of sunlight, which is why window frames designed for flat roofs become a key element.
Aesthetics must go hand in hand with the highest technical requirements here. A window on a flat roof must be able to withstand the difficult conditions of the Polish climate (lingering snow, downpours) and have excellent thermal and acoustic insulation parameters. The Polish company OKPOL offers a wide range of solutions ideally suited to such needs.
Recommended models of OKPOL windows for flat roofs:
Non-opening windows (FIX version) - e.g. OKPOL PGX A1 model: This is an ideal solution for corridors, living rooms or dressing rooms, where all we care about is maximum interior illumination with natural light, without the need for additional ventilation.
Openable windows - e.g. OKPOL PGC A1: An excellent choice for bathrooms, laundry rooms and kitchens located deep inside the house (without access to façade windows). The opening sash (often integrated with an electric actuator) allows quick and efficient ventilation of the room.
**Windows with frosted/frosted glass (e.g.
pGX line with see-through glass):** They work well in places where you want to let in light but want complete privacy and intimacy (e.g. above a bathroom shower).
Flush-to-floor windows (so-called "walk-on"): For green roof and terrace lovers, the brand offers packages with toughened glass that can be walked on freely and safely, allowing maximum use of the terrace space.
Design options: In modern interiors, flat roof windows illuminated with LED strips are great for creating an amazing atmosphere in the living room or bedroom after dark.
When choosing solutions for a flat roof, there is no room for compromise - neither visually nor functionally. The correct installation of windows (especially the precise processing of connections to the roof covering with a minimum pitch) carried out by a professional roofer is a guarantee of safety. If you decide on such an original project, a holistic approach will ensure that your dream terrace or relaxation area "between heaven and earth" will be enjoyed by all household members for many years.
