What box sizes are available for Oman Mini Polar and what opening should be prepared?
Oman Mini Polar is listed in LATIVA with lengths of 90, 100, and 110 cm and widths of 50, 55, 60, or 70 cm. These are the external dimensions of the box. The official chart requires the installation opening to be 2 cm larger in both directions. For the 50 cm width options, the manufacturer explicitly states that a railing cannot be installed.
What thermal insulation does the attic ladder cover Oman Mini Polar provide?
Mini Polar uses a cover with a total thickness of 86 mm and 80 mm of thermal insulation. OMAN specifies a Ud coefficient of 0.36 W/m²K, two peripheral seals, and white color on both sides of the cover. These parameters apply to the specific Mini Polar model. They should not be attributed to Mini Extra or Mini Termo, as their covers, insulation, and Ud values differ.
How is the four-section ladder of Oman Mini Polar constructed?
The Oman Mini Polar ladder is four-section, with wooden and metal elements, and folds into a wooden box 170 mm high. The ladder width is 365 mm, and each step is 324 mm wide and 80 mm deep. The compact geometry is designed for small openings, but the exact variant should be chosen according to the available space for the box and unfolding.
How much free space is needed to unfold the Oman Mini Polar?
The maximum room height for Mini Polar is 265 cm. Depending on the specific size, the required floor space is 142 or 149 cm, and the opening distance is 132 or 133 cm. These are separate dimensions from the technical diagram and should not be confused with the box size. Before installation, height, free floor area, and opening direction must be checked simultaneously.
What is the maximum load of Oman Mini Polar and what supports does it have?
The manufacturer specifies a maximum load of 160 kg for Oman Mini Polar. The ladder is equipped with anti-slip tips, and for widths over 50 cm, a railing can be used; for 50 cm boxes, the railing is excluded in the official chart. The load applies to a properly installed and fully unfolded ladder, so the box, sections, and floor support must be checked before use.
How does Oman Mini Polar differ from the compact Mini Extra model?
Mini Polar is the version with a thicker cover and lower Ud value. Its cover is 86 mm thick, insulation 80 mm, with two seals and Ud of 0.36 W/m²K. Mini Extra has a 46 mm cover, 40 mm insulation, one seal, and Ud of 0.85 W/m²K. The size ranges also differ, so the choice is made based on both the opening and the required thermal parameters.
