The Merlin door is a doorset that comprises of a pre-finished, engineered timber door leaf and frame, complete with hardware and glazing, which is supplied as a ready-to-install unit. Independent tests have shown it to provide the solution to the problems encountered by most residential doors. Thanks to its revolutionary design, the door-set is weather resistant and forms and effective barrier against intruders.
The Merlin door is easy to maintain and repair and is made-to-measure in a wide range of styles and colours. Our supplier has in excess of 80,000 doors in current use and has over 24 years of experience in the entrance door market.
The Merlin door SR has a PVCu frame. The multi-chamber hollow extrusion is produced from the same materials and to the same standards a PVCu window sections. The dimensional stability, surface finish and colour fastness are identical to window profiles. Aluminium reinforcement is situated in the centre section of the profile.
PVCu sections are welded to form the jambs and head of the frame. The threshold is mechanically jointed to the bottom of the frame. Q-lon gaskets are applied to the double rebate, having a continuous weather seal around the inner rebate and along the threshold.
The Merlin door SP is an aluminium composite frame. Facings of either hardwood or PVCu are screwed to the aluminium core. This means that the facings of the frame can be repaired or replaced in the event of them becoming damaged.
The PVCu facings are available in white or mahogany woodgrain. Optional hardwood facings are available in any British Standard colour
The Merlin door SP is also available as a 30 minute fire door. Intumescent materials are applied to the frame, locks and letter plate to stem the flow of flames and hot gasses. PVCu facings may be used on the non-risk side of the door, but hardwood facings must be used on the risk side of the door. The Merlin door meets the requirements of BS476 pt 22. Independent test reports are available on request.
The Merlin door can be supplied with either integral or coupled fanlights, sidescreens or flag windows in a range of framing materials. There are a number of coupling mullions which enable frames of differing dimensions to be jointed with confidence. A range of structural mullions are also available for use in ribbon wall assemblies.
The fibreglass doors have a core which is made from expanded foam with internal and external skins made from glass fibre. Fibreglass is a very stable material for door skins because it has a very low expansion rate. This means that if it is painted a dark colour it will not expand and contract as much as other materials used for door skins.
