Secondary Glazing is popular both as a genuine alternative to Double Glazing and because it can deliver unique benefits of its own. In this section we have picked out the major benefits in order to provide more detail on them, all of which can be accessed from the image links down the left of this page. These particular benefits are Heat Retention, Noise Reduction, Condensation Reduction, and Low Cost in relation to the alternatives. For good measure we have added a Gallery of pictures from our customers that show off the Easyfix Secondary Glazing products doing the job for which they were designed.

Less Obvious Benefits

Longevity - it sounds paradoxical that a DIY Secondary Glazed panel will outlast a purpose built Double Glazed panel, but this often is the case. Sealed Double Glazed units, once the seal has broken, lose their effectiveness as insulators and will fog internally with condensation. On the other hand, Secondary Glazed panels do not have a seal that will eventually break, so will last just as long as they are required. This will enable you to prolong the life of your original windows, that can literally last for centuries if looked after properly.

Reversible - if you fit Secondary Glazing it is a relatively simple matter to take it down and return the outer windows to their previous condition. Contrast this to ripping out old frames for new replacements, and the finality this entails.

Repairable - once a Double Glazed unit is damaged, it is a major job to fix this, and often, repair is out of the question, you must instead completely replace the glass or frame as required. Secondary Glazing however is easier to refresh, be it renewing the edging strip or changing the glazing sheet. Tubeway have many customers who repair Secondary Glazed units that are decades old, simply by taking them down and changing the flexible edging, re-using the glazing sheets.

Local Authority Approved - in general, Secondary Glazing is much more likely to get approval, as it is much more sympathetic to listed and historical buildings, mainly because it can be fitted so it is not seen from outside. This enables you to retain the essential character of your home. Add to this the ability to take it down with minimal damage, and it balances the householder's need for energy saving with the general need to preserve beautiful and important buildings. Please note that you should still check with your relevant authority before purchase and installation.

Carbon Footprint - if you consider the resources involved in removing and destroying your old windows, manufacturing PVC frames and sealed glazed units, the removal and replacement of these units when they fail (typically within 10-15 years, but sometimes sooner), and subsequent disposal of non-recyclable waste, it adds up to a lot of energy and resources. Contrast that with Secondary Glazed units, with lighter frames, simple no-nonsense glazing and no disposal and you will see why the Carbon footprint compares very favourably.

Retrofitting - not only can you put up and take down your Secondary Glazing systems each autumn and spring, but you can change them more easily and retrofit them to most windows far more easily than a fixed window system. This places your glazing within the realm of a competent DIYer rather than needing a team of professional tradesmen to make any changes.

Compromises With Any Glazing System

Secondary Glazing is no different to any insulation or draught proofing method in that it can deliver many benefits, but some of these benefits can conflict. The most immediate example is regarding condensation vs heat retention, because reduction in condensation generally requires warm moist air to be removed from your living space, which will usually mean replacing it with cooler, dryer air. This will result in a choice for each householder, but we hope that the information we have included on the other pages in this section will explain how to get the best result in every case.
