BUILDING FUNCTION
Hospitals, public conveniences and airport WCs can all create hostile environments for material longevity by virtue of powerful cleaning agents being present.
Swimming pools provide a unique challenge in that the humidity and potential chlorine present in the atmosphere condenses onto fixtures during cooler periods, for example, at night and when the pool is not in use. In addition, modern methods of recirculating pool air (to reduce energy costs) can accelerate the corrosive processes. If not cleaned regularly the result is a build up of layers of highly corrosive chloric acid which can be exceptionally detrimental to inappropriately specified finishes and base materials.
Most door and frame timbers are acidic to some degree. Oak, Chestnut and Douglas fir are the worst due to the presence of volatile acetic acid which will attack metals and electro-plating in contact with the wood or in certain atmospheres. Please contact RT for advice and assistance wherever concerns arise with regards potential corrosive environments.
Hinges – Generic
Generally, single axis hinges are either:
1 Fixed pin; the door is fixed onto the frame and can only be removed by unscrewing the hinge
or
2 Lift-off; where the hinge door leaf can be lifted off the hinge frame leaf so that the door can be easily installed and removed (when the door is open). Lift off hinges are handed left or right.
N.B. There are various methods of handing hinges/doors – Royde & Tucker’s are shown right.
