Application of the SPR-SKY Skylight<\/strong><\/h2>\n\n\n\n

The application of the SPR-SKY<\/strong> rooflight is an effective solution for providing natural daylight inside a building. With roof coverage in the range of 7\u201315%, it can replace electric lighting. The multi-chamber structure of the rooflight limits excessive temperature increases caused by solar radiation while minimizing heat losses inside the building. Rooflights can be used in industrial facilities with pitched roofs (with a slope of more than 10%) in the form of warm covering with sandwich panels. The SPR-SKY<\/strong> rooflight can be installed as a point source of light or as a continuous skylight strip covering the roof from ridge to eaves, in the middle of the roof slope, near the ridge, or from the middle to the eaves. SPR-SKY<\/strong> rooflights connect to sandwich panels via side joints (on ridges) and end joints (overlaps), but the rooflight\u2019s outer skin is 3\u20134 times thicker than the outer skin of the sandwich panel. This means that at overlap joints the claddings do not fit perfectly, so special attention must be paid to sealing during design and installation. It should also be remembered that rooflights are not as strong as the adjacent sandwich panel covering. Therefore, to ensure strength and tightness, installation must follow guidelines and good construction practice.

Application of the SPR-SKY ECO Skylight<\/strong><\/h2>\n\n\n\n

The application of the SPR-SKY ECO<\/strong> rooflight is an effective solution for providing natural daylight inside a building. With roof coverage in the range of 7\u201315%, it can replace electric lighting. The multi-chamber structure of the rooflight limits excessive temperature increases caused by solar radiation while minimizing heat losses inside the building. Rooflights can be used in industrial facilities with pitched roofs, with the minimum roof slope being identical to that required for SPR CORE<\/strong> roof panels (not joined in length and without technological passages), i.e. 5%, in the form of warm covering with sandwich panels. The SPR-SKY ECO<\/strong> rooflight can be installed as a continuous skylight strip covering the roof from ridge to eaves. It should also be remembered that rooflights are not as strong as the adjacent sandwich panel covering. Therefore, to ensure strength and tightness, installation must follow guidelines and good construction practice.
