Frequently Asked Questions
- What is Secondary Double Glazing?
Answer - Secondary glazing is another window fitted on the inside of you existing window, our system is aluminium with a hardwood sub-frame, it is some times called secondary windows.
Question - How do I get a quotation?
- In order to obtain a
quotation we will need to email widths x heights x style (two panel vertical
slider, three panel horizontal slider, hinged unit etc)
Question - Will it eliminate draughts?
Answer - Yes, but we recommend that you draught proof the existing window as well
Question - Will it reduce noise?
Answer - Yes, considerably, for extra sound proofing consider a different thickness of glass to the existing glass, different thicknesses cut out different wave lengths giving improved noise reduction.
Also consider laminated glass for improved sound reduction, apart from ordinary laminated glass there is now a new generation of acoustic laminated glasses.
For additional reduction of noise pollution leave a 4" (104mm) cavity, line the reveals with acoustic tiles leaving a 3mm gap between the tiles and the prime window. Once again draught proofing the existing window is vitally important, you would be amazed that people/firms do not carry out this basic requirement
Question - Will it reduce heat loss?
Answer - Yes, the cavity formed between the prime and secondary windows is an effective thermal insulator, if the cavity is more than 4" (104mm) then you can get thermal currents within it that will decrease the insulation value.
Question - Will I need to re-decorate?
