Provide natural ventilation whenever possible. Air changes within rooms and dwellings are important when combining with ventilation, i.e. opening of a bathroom window vent after showering or a bedroom window first thing in the morning. In both scenarios the period of time may only have to last 10-15 minutes 


Water vapour will easily drift on convection currents far from where it originated, try keeping internal doors to kitchen and bathroom closed when possible to prevent the excessively moist air in these rooms being transferred to other areas of the house.


Unfortunately, condensation is a fact of life and wherever there is moisture in the atmosphere and substantially differing temperatures on either side of the glass surface, certain degrees of condensation will occur. The effect will be directly proportional not only to this temperature variation, but also to the amount of water vapour present. You can generally expect windows in kitchens, bedrooms & lounges to be most affected. Double glazing, in most cases reduces condensation, but it cannot be claimed to cure the problem. One certainty is double glazing will not create condensation providing air is allowed to circulate within the property.


Maintain some permanent heat in the house during cold weather. Where possible marginally increase the temperature in areas where condensation maybe a potential problem, this may be achievable by the use of thermostatic control valves. (If new radiators are being fitted locate under windows to maintain the temperature of the inside pane of your double / triple glazing).



The window handles incorporate a push button, when this is depressed the handle will turn to the horizontal position enabling the opening of the sash. The handle is also fitted with a key locking barrel which can be used for a higher level of security. When the handle has been locked it is advisable to place the key ‘out of sight’, although it should be placed nearby in case of any emergency. Ventilation is provided by the gearing within the sash engaging into the ‘keeps’ fitted within the outer frame rebate, this function is carried out by the sash being opened & moved outward approximately 12mm then returning to the closed position.

Whilst partially open a flow of fresh air will be able to enter your home. Please note that with this position, the window is not as secure as when fully closed. The standard fitted side-hung fire hinges allow the sash to open at a right angle to the window as means of emergency exit. The Easy Clean Egress hinge has a duel function, it initially performs the same role as the Fire Hinge and then can be moved from either left or right (depending on which side it is hung on) to create a gap for cleaning purposes. To activate this open the sash fully, then place a hand onto the outside face at the bottom of the sash, apply pressure and push / slide across approx. 75mm, repeat this with your hand now to the same area at the top of the sash.

You can now hold the sash with your hands (top & bottom) and continue to slide in the same direction until slightly off centre. The external glass surface can now be reached for cleaning etc. To return the sash to its original position complete the operation in reverse, making sure the opening function works smoothly and the lock mechanism engages correctly. The final location may require exerting slightly more pressure so as to secure the pivot point. 


The handle will incorporate a key locking barrel, when closed the handle will be vertical and pointed downward, to open, first unlock the handle via the key, rotate the handle horizontally. The sash will then tilt inward from the top while pivoting from the bottom until it reaches its rest position approximately 75mm > 100mm this provides ventilation into the home. Reverse to close. With large openers it may be necessary to assist the opposite side with a hand so as to gently push forward until vertical against the main frame. To engage the 'Turn' facility, for cleaning & access, the sash will open inward (pivoting at side) from the closed position with handle vertical and pointed downward, rotate until upright and vertical, then gently pull the sash inward as required. Reverse the operation to close.


To slide & open, disengage the central catch on the top of the horizontal meeting rail between the sashes and slide either up or down. Reverse to close and secure. For the cleaning and tilt facility disengage the central latch & slide bottom sash upwards slightly, then disengage both push knobs on either side of the meeting rail. Pull the top of the sash gently inwards, slide the upper sash down at same time gently pull the sash inwards. Reverse to close the catches will automatically re-engage. This procedure allows for cleaning but the bottom sash will need to be in the tilt position first – in some foiled colour options only one sash is operable to do this.


There are two types of handle for single opening door the most commonly used type is the Lever/Lever style (both handles are the same inside & out). To lock from outside or inside lift the handle upwards to its maximum position, insert the key and turn clockwise. Reverse the operation to unlock depressing the handle downwards. If a thumb turn cylinder is fitted the procedure is the same but when inside, instead of inserting the key simply turn the thumb turn clockwise. To unlock turn it anti-clockwise then depress the handle. 

The other type of handle is the Pad/Lever, this works similar to a traditional door lock. When the door is closed it can only be opened from the outside with a key which releases the latch. This means the door can be pulled closed whilst providing easy exit for day-to-day use, this does not benefit from the high security lock & weathering performance as the main gearing has not been engaged and it is recommended that the lock is fully operated. To unlock the pad handle externally, insert the key & turn anti-clockwise, push the pad down which will release the high security locking system but not the latch. Turn the key once more anti-clockwise to retract the latch the door can now open. The internal operation of locking and unlocking with a key cylinder or with a thumbwheel cylinder remains the same as described above.


Double Lever/Lever style handles are fitted on all French doors, the main opening door leaf is known as the ‘Master’ the other leaf is termed the ‘Slave’. Both door leafs will open fully when unlocked. If only the Master is to be opened then repeat the procedure described above, if the Slave is to be then opened repeat same operation. Both doors can be opened in unison by turning both keys and depressing both handles simultaneously. When closing from a fully opened position the Slave leaf must be engaged first then the Master to follow (both keys to the door cylinders are paired – and thumb turn cylinders can also be specified).


To unlock – insert key into barrel, turn anti-clockwise and push lever upwards. Pull handle to slide door open. To lock the door simply close door shut, push the lever downwards and turn the key clockwise.


It is essential that your door is not slammed with the handle in the up or locked position as this may damage the lock or related hardware. Any aggressive use may eventually warrant adjustment or a lock repair. Similarly, do not slam the door closed again this may result in subsequent damage as before or in severe cases cause the rollers to `jump` off the track. 

Please note: All doors should always have the locking system fully engaged when closed this is to ensure maximum performance for integrity, security and maintain an airtight seal.
