Some applications are listed below:
- Swimming pools
- Commercial kitchens
- Pharmaceutical and biotech facilities
- Veterinary surgeries,
- Theme and water parks
- Dog kennels
- Zoos and aquariums
- Breweries and bottling plants
- Hydrotherapy rooms
- Meat processing factories
- Chemical processing plants
- Paper pulping facilities
- Wet markets
Dortek Waterproof GRP doors will not rust, rot or warp in wet conditions unlike steel or timber laminate doors.
Dortek waterproof GRP doors have a moulded one piece construction with no joints, seams or crevices. The door is not made up of individual sheets and lippings but instead is pressure moulded for a smooth seamless fully encapsulated finish which is easy to clean, waterproof and resistant to harsh cleaning regimes.
Whilst materials such as hard plastic laminate are undoubtedly waterproof a very important consideration is how you then make this flat sheet material into a door. The answer is by using adhesives and lippings all of which are weak points in the doors construction and over time the combination of water / cleaning agents and wear through traffic using the door will break down the door construction. This is elevated to an even greater problem if the core material used is timber as this absorbs moisture, swells and both stops the door from functioning and supports fungal / bacterial growth.
Steel is a sheet material and must be formed into a door which again leaves folds, joints and welds which are weaknesses. Coated steel can be waterproof but again traffic wear will breakdown the coating leaving the core material to corrode. Steel is also a much heavier material than GRP and so doors manufactured from steel are harder to operate, less user friendly and have higher lifecycle costs due to wear on hinges and closing devices.
Dortek waterproof GRP doors have been tested to various international standards and therefore offer the unique combination of proven water and fire resistance.
Dorteks patented intumescent strip which seals the door under fire conditions is concealed beneath the frame and door surface and therefore is not open to attack by moisture.
In contrast doors with exposed intumescent are open to moisture and the intumescent will degrade and affect the performance of the fire door. Open ends to the intumescent strip at the top and bottom plus hinge and lock locations mean the intumescent material can fall out contaminating the area around the door. Lastly the cut out in the door and frame which houses the intumescent strip is both a dirt trap and potential structural weakness particularly at the leading edges of the doorblade.
