The Stira trapdoor is now insulated and features a draught seal, this ensures the trapdoor is airtight preventing any unwanted draughts getting in and stops heat from escaping through the Stira trapdoor. The wraparound overcomes this problem by wrapping around the side stringer of the ladder and being screwed in place on all 3 sides spreading that pressure across a wider area. The hinge on the first fold of the ladder is under the most pressure, over time the hinge can slowly be pulled out of the timber by the weight that is put through it. This hinge on the bottom fold on the ladder.
As we don’t attach the ladder directly to the trapdoor this allows the standard lid of the Stira to be replaced with an alternative lid of the customers choice. The inner frame of the Stira that attaches the ladder to the outer frame is unique to Stira, this rigid frame allows us to vary the opening size of the Stira making it much bigger or smaller without affecting the mechanics of the stairs. The outer frames importance is often overlooked but it is essential as this frame will be carrying the weight of the stairs through the hinges and linkage arms, which are the main load baring parts of any folding stairs or loft ladder. The Stira folding attic stairs features a substantial outer frame which is 108mm x 32mm, this deep frame gives the Stira a solid attachment to the joists in the attic. This item can be added at a reduced rate with your loft ladder purchase. This gives you added security when getting towards the top of the loft ladder. The deluxe loft handrail for the Stira Loft Ladder sits in the loft and is secured to the loft floor. It has unique design features that allow the stairs to be highly flexible so it can be custom built either for extra high ceilings, extra large trapdoor openings or for tight spaces where walls obstruct the normal use of a folding attic stairs or loft ladder. The Stira Semi Automatic Electric Timber Loft Ladder is designed to be a strong domestic attic stairs that will last a lifetime. This means if anyone was to accidentally get a finger or hand stuck in the trapdoor whiles its closing the Stira will know this and perform an emergency stop.
