Core Timber’s non-compromising Lift & Slide low threshold door system is for achieving the maximum amount of light ingress. With the unique fittings system by Siegenia, we are able to produce lift and slide doors with a width of up to 8 meters and a maximum height of 2.8 meters with maximum number of 4 leafs.
