What kind of cover and seals is the Oman Maxi attic ladder equipped with?
The Oman Maxi has a 56 mm thick cover with 50 mm insulation. The manufacturer specifies Ud 0.7 W/m²K and two peripheral seals. The cover is white on both sides. The combination is specific to the Maxi: it differs from the Extra with a 46 mm cover and from the Polar with an 86 mm cover, so technical values should be compared by the exact model.
What external box sizes are available as options for the Oman Maxi?
Shopify options for the Oman Maxi are 120 x 55, 120 x 60, 120 x 70, 130 x 55, 130 x 60, and 130 x 70 cm. OMAN defines these as external box dimensions, and the installation opening must be 2 cm larger. So for a 130 x 70 cm box, the required opening is 132 x 72 cm. Always measure the finished construction opening before choosing.
What opening space should be allowed for the Oman Maxi?
For the Oman Maxi, the official diagram indicates a maximum floor space of 151 cm and an opening distance of 168 cm. The maximum room height is 280 cm. These three values describe different parts of the geometry and must be checked simultaneously. Having a suitable attic opening alone is not enough if furniture, walls, or other structures fall within the unfolding area.
What is the construction of the Oman Maxi wooden ladder?
The Oman Maxi uses a three-section wooden ladder with a total width of 400 mm. The steps are 358 mm wide and 80 mm deep, and the wooden box is 170 mm high. The handrail can be mounted on the left or right side, and there are anti-slip caps at the bottom end. The construction must be sized to the exact height to rest properly on the finished floor when fully extended.
What is the allowable load for the Oman Maxi?
The maximum allowable load for the Oman Maxi is 160 kg according to OMAN. This value applies to the ladder when the box is properly secured, sections correctly adjusted, and the caps have stable contact with the floor. It is not a reason to skip checking the supporting structure around the opening. If there is doubt about beams, sheathing, or insufficient support, the installation should be evaluated before using the ladder.
When are the technical parameters of the Oman Maxi more suitable than those of the Oman Polar?
Maxi and Polar have the same maximum height of 280 cm and similar three-section wooden ladders, but their thermal parameters differ. Maxi has a 56 mm cover, 50 mm insulation, and Ud 0.7 W/m²K. Polar has an 86 mm cover, 80 mm insulation, and Ud 0.36 W/m²K. The choice is made based on the required insulation and available box sizes, not just the series name.
