Can Oman Long Extra from LATIVA be used at a height of 330 cm?
The Oman Long Extra options in Shopify are explicitly marked H330, and the official OMAN catalog from 2017 also specifies 330 cm for this generation. The current product page now describes a generation up to 310 cm. Therefore, when ordering for a height over 310 cm, it must be confirmed that the delivered item is indeed the H330 version of the chosen SKU, not the current shorter configuration.
What thermal insulation does the Oman Long Extra cover have?
The Long Extra has a 46 mm cover, of which 40 mm is insulation, with a Ud coefficient of 0.85 W/m²K according to OMAN. The cover is white on both sides, and the system has a single seal. This configuration is better insulated than the Long Termo PS with a 26 mm cover and Ud 1.22 W/m²K. The actual result also depends on a tight, properly insulated installation around the box.
How is the wooden ladder of the Oman Long Extra constructed?
The model uses a four-section wooden ladder with a maximum load of 160 kg. Official data indicate a ladder width of 400 mm and steps measuring 358 × 80 mm. Anti-slip end caps and a sturdy handrail, which can be mounted on the left or right, are provided. The load capacity refers to a properly installed and adjusted product and does not replace the inspection of the supporting structure around the opening.
What unfolding space should I leave for the Oman Long Extra?
The official technical table gives 165 cm of occupied space when unfolded and a 167 cm opening radius. These values should be marked on the plan from the edge of the attic opening to avoid furniture, doors, or communication lines. The wooden box is 170 mm high. The box size alone is not sufficient to judge whether the ladder will unfold freely in the room.
What opening sizes are available for the Oman Long Extra H330?
LATIVA offers nine H330 variants: lengths of 120, 130, or 140 cm combined with widths of 55, 60, or 70 cm. These sizes match the official standard table for Long Extra. OMAN specifies that the installation opening should be 2 cm larger than the external size of the box. Choose a variant after measuring the finished opening in both directions.
What is the practical difference between Oman Long Extra and Long Termo PS?
Long Extra has a thicker cover and insulation: 46/40 mm and Ud 0.85 W/m²K, while Long Termo PS is 26/20 mm and Ud 1.22 W/m²K. Both models use a four-section wooden ladder and are for high rooms, but Long Extra is more suitable when heat loss through the attic opening is more critical. The comparison of H330 variants is made by the exact SKU and generation.
