The Quadro DD wooden loft ladder is the solution when ‘standard’ is simply not good enough. It is supplied as an easy to fit, made-to-measure unit. It also features an upper loft hatch that provides improved thermal insulation. In addition, the upper cover can be closed immediately after entering the loft, therefore preventing the flow of air. This not only helps to lock the warmth in the home or building, but also prevents moist air from flowing into the loft and condensing in the cold areas. Furthermore, the Quadro DD is suitable for ceiling heights of up to 3.44 m.

Case Studies

Quadro wooden pull-down loft ladder for small ceiling opening. Premier Loft Ladders

Wooden pull-down loft ladder for a small opening

After over 30 years of regular use, Callan Cessford’s pull-down loft ladder was in need of replacement. He needed a new loft ladder that would fit within the existing opening and was easy to use. Furthermore, Callan preferred the loft ladder to be made from wood, like his current one. The made-to-measure Quadro offered the ideal solution for Callan’s needs.

“The person who helped me has been a carpenter for over 50 yrs. He was impressed with it.”
