MAINTENANCE GUIDE
Glass Cleaning
- Float glass, used in most double glazed units, is easily scratched and it is therefore recommended that hand jewellery is removed prior to cleaning
- Any proprietary household cleaner may be used with a soft cloth and it is recommended that heavy external grime be initially removed with a solution of soap and water
- Laminated glass, or glass containing Georgian bars, is cleaned in exactly the same manner
Leaded Glass Cleaning
- In this type of double glazing, lead strips are bonded to the inside of the unit in diamond or square patterns
- Take care when cleaning leaded lights as excessive pressure might dislodge the lead from the glass surface
- The use of warm soapy water and a soft cloth, moderately applied will prove an adequate cleaning method
- Note: External lead will oxidise. This is a natural phenomena and cannot be avoided.
Scratched Glass
If scratches occur, most can be removed with jewellers rouge, or an equivalent rubbing compound.
Glass Defects
All double glazed units are susceptible to a degree of surface damage during the manufacturing process. Certain imperfections in the glass cannot be avoided, even in the most carefully controlled production environment.
Such blemishes and imperfections are inherent in all double glazing and therefore beyond our control, but are considered acceptable by the most rigorous industry standards.
We wish to draw your attention to the following extract from an industry accepted standard, relating to glass generally.
- Transparent Glass, used in the manufacturing of double glazed units is identical to that used in traditional single glazing and will therefore have a similar level of quality
- Both panes of the double glazed unit shall be viewed from the room side, standing at a distance of two meters (6.5’) in natural daylight and not in direct sunlight. The area to be viewed is the normal vision area, with the exception of a 50mm (2”) wide band around the perimeter of the unit
- Flat transparent glass shall be deemed acceptable if the following phenomena
are neither obtrusive or bunched;
a. Totally enclosed seeds
b. Bubbles or Blisters
c. Hairlines or blobs
d. Fine scratches not more than 25mm (1”) long
e. Minute embedded particles - Obtrusiveness of blemishes shall be judged by looking through the glass
and not at it, under normal light conditions as described in point 2.

PVC-U Frame Cleaning
- Avoid all solvent based or abrasive cleaning
- Wash frames with a soap and water solution every four months to remove any grime and atmospheric deposits
- If required, clean with a non-abrasive proprietary cleaner to remove any stubborn blemishes
- Take care not to disturb sealants.
Conservatory and Porch Roof Cleaning
- Avoid all solvent based or abrasive cleaning
- Polycarbonate roofing panels fitted to these structures must be cleaned in a similar manner to PVC-U frames
- Clear gutters of leaves and debris as required avoiding overflow of rain water and ensuring unobstructed drainage
- Wash roof panels with soap and water solution every four months to remove grime and atmospheric deposits
- Do not walk on conservatory roofs.
Drainage
- Your double glazed products are designed with an in-built drainage system, comprising slots within the thresholds that allow any water ingress to flow to the outside. To ensure an efficient system these slots must remain unblocked
- Periodically, remove dirt, clear drain holes and check drainage operation by flushing through with water.
Weatherseals
- During cleaning and general maintenance ensure that the weatherseals fitted to your products do not become dislodged from their groves. Should this occur, slide back into position immediately to avoid damage when the product is closed.
Condensation
Water vapour is continually present in the atmosphere
In the home, this natural water content is increased by normal day to day living. For example, activity that generates steam such as cooking, bathing, laundering, boiling a kettle or even breathing.
The water vapour remains undetectable while floating in warm air but upon contact with cold surfaces: windows, mirrors, tiles etc, condensation occurs and the vapour turns to water droplets.
Traditional house construction allowed the escape of this water vapour through natural ventilation – open flues of coal fires, air bricks and ill fitting windows and doors.
The drive to conserve energy and reduce heating costs has led to the sealing of homes, resulting in trapped water vapour and increased problems of condensation.
- Provide natural ventilation whenever possible by opening a window or fitting wall vents to provide air flow
- Maintain some permanent heat in the house during cold weather. Marginally increase the temperature in areas where condensation is a particular problem
- If possible, fit radiators under windows to maintain temperature of the inside of your double glazing
- Keep internal doors to kitchen and bathroom areas closed and draught sealed, where possible, to prevent the excessively moist air in these rooms being transferred to other areas of the house
- Bedroom windows should have a night ventilation facility to provide
air movement.
