{"product_id":"heavy-duty-aluminium-concertina-loft-ladder-insulated-hatch","title":"Heavy-Duty Aluminium Concertina Loft Ladder with Insulated Hatch – 200kg Treads, 4 Opening Sizes","description":"\u003cp\u003eMost loft ladders are built for an occasional trip up to fetch the Christmas decorations. A loft used as real storage — or a roof void that a tradesperson has to get into with tools every few months — needs something closer to a staircase: wide, flat treads, a high load rating and a mechanism that will still work smoothly after years of use. This heavy-duty aluminium concertina loft ladder is that product. It retracts vertically into a highly insulated, airtight hatch box so it takes almost no space in the loft, and it opens with a spring-assisted action that makes a 200kg-rated ladder feel light in the hand.\u003c\/p\u003e\n\n\u003cp\u003eIt is supplied as a complete, made-to-measure unit: pressure die-cast aluminium ladder, insulated hatch box and door, and the operating hardware, built for your opening size and standard floor-to-ceiling range.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cp\u003eLoad capacity of 200kg per step — well above the typical 150kg of standard timber loft ladders, so it suits carrying tools or boxes up and down. A concertina (scissor) action that retracts straight up into the hatch box, so no swing space is needed below the opening and nothing intrudes into the loft. A highly insulated and draught-sealed hatch with a U-value of 0.58 W\/m²K, closing one of the most common heat-loss gaps in an insulated roof. Four opening sizes, with a standard 2200–2790mm floor-to-ceiling range that covers most UK homes.\u003c\/p\u003e\n\n\u003ch3\u003eSuitable applications\u003c\/h3\u003e\n\u003cp\u003eHomes where the loft is used for regular storage; landlords and housing providers who want a ladder that stands up to heavy use; lofts holding plant such as water tanks, MVHR units or solar inverters that need routine access; and any ceiling opening where a fold-down timber ladder would need more swing room than the landing allows.

The hatch box is fixed through its frame into the trimming joists and the ladder is then adjusted so its feet sit flat on the floor when fully extended. Because the ladder retracts vertically, check there is clear headroom directly above the opening in the loft for the folded stack.
