What are the dimensions of Oman Flex Polar and how large should the installation opening be?
Oman Flex Polar is available with external box dimensions of 120 x 60 and 120 x 70 cm. For installation, OMAN requires the opening to be 2 cm larger in both directions, that is, respectively 122 x 62 or 122 x 72 cm. Before ordering, the room height and free unfolding area must also be checked, as they are not determined solely by the size of the opening.
What is the insulation and Ud value of the cover on the Oman Flex Polar attic ladder?
The Flex Polar cover has a total thickness of 86 mm and contains 80 mm of thermal insulation. The manufacturer specifies Ud 0.36 W/m²K, two peripheral seals, and white coating on both sides. The model is also rated class 4 for airtightness according to EN 14975. These parameters apply to the Flex Polar version and should not be transferred to the Flex Termo, despite the similar type of folding ladder.
How is the metal accordion-type ladder of the Oman Flex Polar constructed?
Flex Polar uses a metal accordion-type ladder with 10 steps, folded inside a wooden box with a height of 170 mm. The ladder is 390 mm wide, the usable step width is 345 mm, and the depth is 80 mm. This construction unfolds downward, so when sizing, the entire trajectory must be considered, not just the space directly under the attic opening.
How much space is needed to open and step on the Oman Flex Polar?
The technical diagram of Oman Flex Polar specifies a maximum floor space of 210 cm and an opening distance of 245 cm. The maximum room height is 290 cm. These three values describe different constraints and must be checked separately on site. There must be no wall, door, furniture, or other permanent element in the unfolding trajectory that would obstruct full opening.
What load does the Flex Polar support and is there an additional step?
The maximum load specified for Flex Polar is 160 kg. The product table includes the additional step, and the cover is sealed with two peripheral strips. The load applies when the box is properly secured and the metal ladder is fully unfolded. Before use, it must be checked that all hinge sections are fully open and that the lower support rests firmly on the finished floor.
What is the technical difference between Oman Flex Polar and Flex Termo?
Both models have 10 steps, a maximum height of 290 cm, and the same floor area requirements, but their covers and boxes differ. Flex Polar has an 86 mm cover, 80 mm insulation, two seals, Ud 0.36 W/m²K, and a 170 mm box. Flex Termo has a 26 mm cover, 20 mm insulation, one seal, Ud 1.22 W/m²K, and a 135 mm wooden box.
