6.3.2 Door Glazing Packer Positions A - Bridge Packer Use on lower horizontal rails, min.2 per rail. Position must not interfere with drain slots. Additional packers are required for lengths greater than 1500mm. B - Glazing Packers Use to pack the glass into the apertures. C – Additional Glazing Packers Positioned adjacent to locking points in sashes and frames, and to space the glass on longer frames. D - Door Multipoint Lock E - Door Hinge F - Run up block G - Anti-lift blocks 6.4 Final Inspection The VEKA UK Group promotes best practice with regard to glazing. It is essential that site glazing is completed as per the recommendations set out. For more detailed instructions, we recommend that the installer familiarises themselves and works in accordance with the latest issue British Standard, BS 6262 Glazing for Buildings. On completion of glazing, and the attachment of any special fittings, check the correct functioning of all windows and doors installed making adjustments where necessary. The protective tape on the framing can then be removed. Apply a good quality low modulus silicone sealant to the joint gap between frame and structure on the outside. Care should be taken not to seal the drainage path for such as metal lintels. The ‘Robust Detailing’ methods referred to in the Building Regulations stipulate that an additional seal line is also placed to the inside gap between frame and structure on new build applications. The use of backing strips for gaps between 6mm - 15mm should be adopted, and the sealant manufacturer’s guidelines followed. Once installation is complete, a final inspection should be carried out, preferably with the purchaser to ensure that the installation is fully in accordance with the surveyor and manufacturer instructions. A final check list can be written and checked. Please ensure that the purchaser is aware of the operating methods regarding locking, unlocking and fire egress. If possible, it is good practice to ask the purchaser to sign off the installation after the inspection has been passed. 7.0 Cleaning, Maintenance and Safety in Use. Your new PVC-U windows and doors are designed, manufactured and installed to the highest standards improving not only your home’s appearance but making it more secure, warmer and more comfortable. New PVC-U windows are extremely durable and long lasting and as a result will only require occasional cleaning and basic maintenance. By following these simple guidelines, they will give you years of trouble free use. • Opening windows. • Ensuring trickle vents remain permanently in the open position. • Use exhaust fans whilst showering and cooking. • Close doors to other rooms so that the moisture does not migrate. • Reduce the amount of house plants in the room. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY INVALIDATE YOUR GUARANTEE • Do not dry damp clothes in a room when it is not ventilated. 7.1 Vents and Ventilation 7.3 External Condensation Your new windows will be much more efficient and draught proof than your old ones and as a result will prevent heat as well as moisture from escaping. Where glazed-in or trickle vents are present in the window, they should remain open at all times even where they may be closeable via a shutter or pull cord. This will help prevent mould and condensation forming in the room and on the windows. Occasionally you may get condensation forming on the external pane of glass. This is usually visible on cold, clear mornings for instance in frosty weather. This phenomenon occurs because modern glass coatings and gas filled cavities have become so efficient at keeping the heat inside the room that warmth is not able transfer to the external pane to heat it up. This is not a product fault and as the daytime temperature rises the external condensation will disappear. WARNING - It is imperative that vents remain open at all times in rooms where there are combustible appliances as to close them or block them up could lead to serious health and safety implications where carbon monoxide could be present. 7.2 Internal Condensation Condensation is caused by a number of factors and is affected by complex interrelationships between heat, moisture, air movement and building layout. The requirement for more efficient use of energy has led to increased levels of thermal insulation and airtightness in both new and refurbished buildings which in-turn can lead to an increase of condensation. This can be a particular problem in rooms where high humidity and water vapour is present such as kitchens and bathrooms. Additional items such as house plants, clothes drying and storage of fire wood can also have an effect. The VEKA UK Group does not guarantee that its products will be free from condensation and does not accept liability for any loss or damage as a result. Condensation is caused by poor ventilation and not by double glazing but because of its superior insulating properties, can contribute to preventing it from escaping. Taking steps to control the amount of moisture created in a room is the most effective solution. Therefore ensure rooms are well ventilated by; 12 Handling, Installation, Maintenance and Care Guide – V2 – 09/14 13
