44mm solid core composite doors with an ultra-thick layer of GRP
An iteration of the successful Solidor composite door system, Residor composites crafted by Listers Central Ltd are supplied to emphasis security over anything else. Document Q ready and PAS24: 2016 approved, Ultion cylinder locking is integrated as standard into every 44mm thick Residor to provide the ultimate defence. Residor’s defining trait is its extra thick layer of Glass Reinforced Plastic or ‘GRP’, with the unnoticeable weather-resistant plastic coming in at 3.6mm as which is more than double the typical layer of just 1.6mm.
All this is accomplished while retaining the inherently classical woodgrain aesthetic composite doors are known for, delivering ‘A’-rated levels of energy efficiency that simply was not previously possible with original timber entrance units. All come handcrafted by the Listers Central Ltd team in-house, fitted in an outer PVCu frame that’s either sculptured or chamfered.
