Modern construction technologies make it possible to reduce the cost of house projects, while at the same time giving them a stylish European look. This also applies to flat roof frame buildings. More and more often you can find in suburban areas beautiful modern buildings with large panoramic windows in the Art Nouveau, hi-tech, cubism style. In the article we will tell you what are the advantages of such houses, and what problems they have.
Advantages and disadvantages
To fully understand the advantages and disadvantages of frame buildings will help a minimum knowledge of how such structures are assembled, and what a flat roof is.
What is a frame house?
The building is based on a frame made of timber and planks (or from a metal profile), which determines its name - frame. The box is formed by vertical racks, the bottom strapping is made along the foundation, and the top strapping is made at the top of the racks. Insulation layers are laid between the frame. Then, with slabs or sheets of building materials, the house is sheathed outside and inside.
How does a flat roof work?
Now let's move on to the flat roof device. It still has an angle of inclination, but since it is only 5 degrees, it is impossible to visually notice the direction of the bevel. The slope is done by raising the height of one of the walls or using an additional beam.
The flat roof of block or brick houses is formed with concrete slabs. For frame structures, they constitute too much of a load. Therefore, roofs are assembled from various materials and resemble a layer cake.
The collection of the roof begins with the installation of beams (beams) with a section of 150x150 mm. They are attached to the top harness. Then, from boards, OSB boards or plywood with moisture-resistant characteristics, a dense sheathing is made with a gap of 1 cm. It becomes the basis for both the ceiling structure and the roofing.
The next layer of the "pie" is vapor barrier. It is often made from inside the building: first, the film is stuffed directly onto the beams, and then the crate is installed along it. This layer protects the roof structure from the destructive effect of steam emanating from the living space.
The insulation is installed over the vapor barrier film. It can be polystyrene foam boards, mineral wool, perlite.
Then, on top, on the thermal insulation, a bituminous or polymer waterproofing layer is laid, which protects the roof from moisture. You can use a more flexible membrane waterproofing, it is more expensive, but has a long service life.
There are different options for flat roofs. The customer himself decides which of them he wants to see on his cottage.
Unexploited. An inexpensive type of roof, which is based on corrugated board. During repair work, ladders are installed on the roof plane, since the coating can deform under a walking person
Operated. A more expensive type of roof. It has good rigidity, allowing not only to move, but also to equip a recreation area or a platform for viewing the outskirts on the roof of the house
Soft. You cannot walk on such a roof, it is really soft and squeezes under the steps. The thermal insulation layer (mineral wool) is covered with roofing material and does not create rigidity
Inversion. On this type of roof, all the materials that make up the "pie" are stacked in the reverse order
Ventilated. The roof contains aerators that allow the soft roofing cake to dry out and restore its properties. The device is a polypropylene pipe with a cap that protects the fan from rain and snow.
Now that we know what frame houses and flat roofs are, the strengths and weaknesses of such structures become clear.
Advantages of flat roofs
Let's first look at the benefits of a flat roof
- Due to the lack of a rafter system that uses a large amount of wood material, flat roof projects are cheaper.
- Building surfaces without slopes is easier, faster and safer.
- It is more convenient to service the equipment brought to the roof - air conditioner units, antennas.
The flat roof does not sail, which is advantageous in regions with strong winds. Problems such as falling shingles are unknown to her. Everything that hits the surface of the house rolls down through the drainage system.
- Rigid roofs represent huge usable areas. They can be equipped with solar panels, a lawn, a sports field, a small pool and a sunbathing area. Most often, the roof plane is used for a recreation area, where not only sets of garden furniture are installed, but also a canopy, a summer kitchen, a shower, and flowerpots.
- The beautiful design allows buildings with flat roofs to look like modern European buildings, in the spirit of our time.
There are disadvantages to a flat roof, but they can be solved with the help of competent design and high-quality construction work
Snow drifts accumulate on the roof in winter; a 5-degree slope is not enough for it to slide off on its own. The problem is solved by a thermal cable system laid on a flat surface. Snow melts and flows through the gutter
- Fallen autumn leaves and small branches will have to be removed by yourself
- In heavy showers, water does not have time to leave the flat roof through the drain, accumulates on the surface and can leak into living quarters. It is important that the roof has perfect tightness and evenness, then moisture does not collect in puddles and does not seep down.
- A flat roof gets very hot during the summer. The premises located underneath will need a reliable split system.
- The absence of an attic floor poorly protects rooms in winter from cold, in summer from overheating, in showers from leaks. You can go for additional costs and build a small attic floor between the roof and living quarters. It will help monitor the tightness of the roof.
The advantages of frame buildings
Today, the developer widely uses frame technologies, especially since they have a lot of advantages:
- attracted by the low cost of buildings;
- buildings are erected quickly in small teams;
- thanks to modern materials, the houses have a good microclimate, they are not cold in winter and not hot in summer;
- low heat capacity makes it possible to heat only the necessary rooms;
- frame technology allows you to lay communications and electrical wiring in the walls, which improves the appearance of the premises;
- due to the lightness of the structure of frame structures, inexpensive shallow foundations are used;
- such houses do not shrink, and you can start internal work immediately after the construction of the building;
frame structures are seismically stable and windproof.
Disadvantages of frame technologies
Now let's talk about the cons of frame houses:
- in regions with high humidity, fungus and dampness may appear in buildings;
- such houses are more flammable than brick or block houses;
- buildings have low noise insulation.
There are few shortcomings, and today frame technologies are used all over the world for the construction of houses as the cheapest and fastest-built ones.
Frame houses are built in one, two, and sometimes three floors. Young people prefer to build housing with a modern design, with a flat exploited roof. We propose to consider in more detail the projects of such buildings with different storeys.
One-story can be both small budget buildings and large-scale cottages with an extraordinary layout, occupying large territories
Frame house with a flat roof, size 14.6x9 m, contains a hall combined with a kitchen and a dining room, 3 bedrooms, a bath complex and a large terrace located at the back of the building (from the second exit).
Project of a modern cottage (11.34x10.7 m). It looks like two one-size buildings connected by a common wall. One part is occupied by a large room that combines the living room, kitchen and dining room. The second part contains two bedrooms and a sanitary room
One-storey house with a flat roof accommodates a living room, a bedroom, two children's rooms, an office and a kitchen. From the side of the dining room, there is an exit to a large terrace
Today it is no longer a rarity for beautiful modern frame cottages, built in two floors, with a flat roof, in the style of minimalism or cubism. We suggest that you familiarize yourself with examples of such projects.
The plan shows the 1st floor of a two-story high-tech house (11.325x11.550 m). The building contains a boiler room, a garage and a large terrace. In fact, half of the floor is occupied by a large hall combined with a kitchen. The sleeping rooms are located on the second tier.
Large cottage second floor plan marked by four bedrooms with dressing rooms
A modern house with a flat roof and a massive balcony, built in the shape of the letter "L". A spacious garage for two cars is integrated into the building
The plan shows the first floor of a two-story frame cottage with an exploited roof, measuring 13.8x13.2 m. The floor contains a living room, kitchen with access to the terrace, garage and technical rooms
Frame houses with a flat roof in the vastness of our country are preferred to build in high-tech style. This direction is characterized by large smooth surfaces, a minimum of decorative elements, an almost ascetic calculation. Whoever prefers coziness, loves to surround himself with cute little things, is unlikely to choose hi-tech.
Initially, due to the cold severity, the style was used only for decorating offices, but over time there were many connoisseurs of minimalist environments. Very quickly it spread in architecture, finding its adherents there too.
The style is characterized by large-scale territories, a demonstration of modern technology, so a gym will be appropriate on the roof, and a home theater in one of the rooms.
High-tech rooms are filled with multidimensional lighting, but the fixtures are chosen with a strict geometric shape.
Frame cottages with a flat roof are built in the style of cubism. The cube house looks good in large open areas. Most often, it has corner glazing, a solid, saturated color, presented in several versions. Cubic houses are endowed with a simple form, practical layout, and an energy-saving system.
An industrial loft-style house can have elements of industrial buildings, or contain a concrete facade. Large windows and quirky walls are in the spirit of the style.
Architectural modernism is associated with the renewal of forms and structural solutions, it lacks the artistic soft, curved lines characteristic of the modernist style of the past.
Homes with flat roofs in the direction of modernism are modern, beautiful and more sophisticated than all the styles presented above.
In cities and cottage settlements today, you can find a lot of examples of beautiful frame houses with flat roofs:
- a tower house with a large balcony and a flat, noticeably sloping roof;
stylish two-tone hi-tech
small modern house
laconic building in the style of minimalism
a cottage with a two-story operated roof
the house is made up of individual cubic units with separate rooms enclosed in each cube.
