GRP dormers: pre-tiled, light weight and safe.
For use on roofs of domestic buildings with pitches ranging from 25° to 70°.
The Stormking Dormer is an all-in-one solution that cuts costs without compromising quality. Extra specialist engineering goes into each dormer’s inner structural support, so you can rely on a safe and sound product that still boasts a refined profile.
Stormking WARMADORMA© prefabricated dormers consist of a structural timber framing which is supplied either fully-bonded to a preformed fire-retardant GRP outer shell, or as a trussed roof to be tiled on site. The dormers are built around a timber framework and, where specified, a preformed GRP moulded outer shell is added and trimmed prior to finishing.
