The Stira Timber Loft Ladders are designed and manufactured to be one of the safest and strongest domestic attic stairs on the market today. These timber loft ladders have unique design features to meet almost every requirement. This allows 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 deluxe loft handrail for the Stira Loft Ladder sits in the loft and is secured to the loft floor. This gives you added security when getting towards the top of the loft ladder. This item can be added at a reduced rate with your loft ladder purchase.
The Stira folding attic stairs features a substantial outer frame which is 108mm x 32mm. This extra deep frame gives the Stira part of its structural integrity and a solid connection to joists in the attic. This extra-strong frame keeps the unit square and makes it much easier to install.
The inner frame of the Stira that attaches the loft ladder to the outer frame is unique to Stira. Where most loft ladders are attached directly to the trapdoor, this product is attached directly to a separate inner frame for extra strength. 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. 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 your choice.
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. In blower tests the Stira trapdoor had a leakage rate of 0.39M3. That's almost half the requirement for a passive house.
The Stira ladder is made from southern yellow pine sourced from managed forests in North America, this is the same timber used in the construction of timber frame houses. We use SAPS grade timber which is a hard wearing timber which features minimal knots or defects. Using a strong timber has many benefits over a metal ladder. While the timber is very strong it remains flexible, and unlike with metal ladders when the timber steps bend under weight they will return to their natural state. The metal step will gradually distort more and more over time which will go on to affect other joints in the ladder.
The inner and outer frame of the Stira stairs is made from White Deal sourced from managed forests in Northern Europe. This is another strong reliable construction grade timber.
The deluxe loft grabrail for the Stira Loft Ladders sits inside the loft and is secured to the loft floor. This gives you added security when getting towards the top of the ladder. This grab rail can be added at a lower cost with the purchase of your ladder.
