The company CIPI, s.r.o. produces and supplies roof skylights to the market, which perform the task of ensuring the penetration of daylight into the building. These skylights can be fitted with openable parts for day ventilation called. (ventilation wings) which ventilate the spaces underneath.
Skylights are fixed to the roof sheathing by means of skylight frames of different heights above the level of the roof sheathing. Thermal insulation is inserted into the edges and everything is closed with waterproofing strips or. plumbing elements to ensure watertightness.
Arched skylights are designed for installation on flat roofs or roofs with a slight slope and are installed on the roof opening or on an opening fitted with a flange or flange. …by the rim. The structure consists of curved aluminium ribs with side base profiles. The polycarbonate is placed on the grid of ribs and a pressure spandrel is applied to the polycarbonate at the rib location, which is inserted into the base profiles and clamped at both ends with metric stainless steel screws through the thread, thus preventing the polycarbonate from loosening on its own.
The benefit of using it lies in the savings in energy costs, maintenance and care of the working environment.
This type is also very suitable for the reconstruction of older gable skylights of steel construction with wire-glass glazing respectively. glass. In this type of skylight, the polycarbonate plates are not drilled during installation, which is a prerequisite for not disturbing the structure of polycarbonate.
Gable rooflights consist of two flat sides that are joined at a certain angle at the top. Once upon a time, this design of skylight was very popular. With the advent of new materials such as polycarbonate and aluminium, the construction of gable rooflights has been maintained, but they are mainly used in commercial and shopping buildings where the architectural design is superior to other factors.
This type of skylight is of course also available with integrated ventilation parts for day ventilation, either pneumatically or electrically operated.
Grey skylights have the illuminating surface oriented to one side of the world (preferably north). The large glazing area enables high daylight values, a favourable brightness to contrast ratio, stability and uniformity of lighting in the building.
The opaque construction of the skylights protects the building from direct sunlight. This type of skylight is of course also available with integrated ventilation parts for day ventilation, either pneumatically or electrically operated.
Point skylights are designed for installation on flat roofs or roofs with a slight slope. The domes are installed on the roof openings. Point skylights are intended for all types of buildings as ceiling lighting of the space, they do not serve as acoustic or fire protection.
Point skylights are also supplied in arched design, this type is interesting for its price, relatively high warranty period up to 7 years (up to 10 years for polycarbonate). This type of skylight is of course also available with the option for day ventilation with either pneumatic or electric drive.
Counter skylights are mainly used for smaller widths of skylights with a requirement for lower light penetration into the space. The light transmission is high, but depends on the colour and thickness of the polycarbonate sheets. This type of skylight is mainly used for smaller opening widths due to the large minimum bending radius of polycarbonate. This type of skylight is of course also available with the option for day ventilation with either pneumatic or electric drive.
The construction of the skylights is made of aluminium certified extruded profiles in shade design:
By illumination resp. the glazing material is polycarbonate chamber plates with thicknesses from 10 mm to 25 mm with a thermal transmittance coefficient Ug from 3.0 Wm2K to Ug = 1.39 Wm2K shade – opal, clear, bronze, etc. The above glazing thicknesses are valid for arched skylights, for grey and gabled skylights the glazing thickness is practically unlimited and it is also possible to use a high quality polycarbonate glazing system based on the tongue-and-groove principle achieving a thermal transmittance Ug <of 1.0 Wm2K. In the case of arched skylights, it is also possible to use sandwich glazing made of two polycarbonate panels where the thermal transmittance Ug 1.06 Wm2K is achieved.
Due to the fact that the materials used (polycarbonate, aluminium) are substantially lighter than conventional glazing made of steel and wire glass respectively. Glass. Which implies that the load roof construction is lower and therefore the cost of roof construction is also reduced. Combination aluminium construction and polycarbonate is also less costly than the combination of aluminium and glass.
Once the skylight is installed, the light transmission into the space is improved. When using a milky colouring called. the opal polycarbonate optimally diffuses light, prevents glare and reduces overheating of the interior space due to sunlight.
As the supporting structure of the skylight is made of aluminium profiles, the operation is almost maintenance-free. For arched skylights with polycarbonate panels, maintenance is self-cleaning, as dirt is washed away by rain.
CIPI s.r.o. also specializes in the reconstruction of older halls and their roofs, which cause large heat losses and leakage into the interior of the building through old roof sheets and skylights. We can support this entire process with thermo-technical and light-technical calculations of heating and lighting savings.
As a glazing material in the 80s. used wire glass resp. glass, which, however, currently does not meet the requirements for heat loss (difference in heat transfer coefficient U e.g. for wire glass thickness 6-7mm U=7,0Wm2k and for polycarbonate e.g. AKYVER thickness 20/7 U= 1,55Wm2k), light requirements and also safety guidelines. Conventional glass shatters into small fragments which, if they fall, pose a safety hazard in the workplace. Therefore, nowadays polycarbonate sheets or safety glasses are used to meet these requirements. Due to their light weight, excellent insulating properties and unbreakability, they are suitable for the reconstruction of older skylights.
The reconstruction of roof skylights includes the following variants:
The reconstruction also includes:
Our company has a clearly defined quality path, which is the basis for our warranty periods that we provide to our customers. For all skylights that are glazed with cavity polycarbonate we provide warranty periods of 5 to 7 years for delivery and installation and up to 10 years for polycarbonate glazing.
With this commitment, we want to make it clear to our customers that the investment they have entrusted to us has a clear foundation and lifetime. We provide regular service on an annual basis according to customer requirements, as well as warranty service within 48 hours of reporting a fault.
