How Glass is Made

A to Z Glazing faq
  • How do I decide what type of glass to use? When buying glass you should tell your supplier the exact position of installation, the use and any known history, for example has it been vandalised regularly? A good professional organisation will be able to advise you.
  • A replacement is needed for my broken double glazed unit, do I need to contact a FENSA Member? No. FENSA deal with frame & glass replacement, not the glass alone.
  • Can I use self-cleaning glass for my shower screen? There would be no advantage to this because that product is designed for exterior use and needs water plus sunlight to activate the cleaning process.
  • I have a broken down double glazed unit, do I need to replace it with another with up to date U values? No, Document L only applies when the whole window, including the frame is replaced. However, Regulations linked to safety will apply.
  • I would like to put a mirror on the wall which houses a plug socket, will I need to have the socked moved first? No. We are able to measure and make cut outs in the mirror to enable sockets to still be used. However, the wiring will need to be long enough to allow for the extra spacing.
  • What is 'U-value'? The U-Value is an indication of how good your windows are at keeping heat in. The lower the U-Value the better the thermal performance, expressed as W/M2 (watts per Metre Square Kelvin)
  • Can we open an account for future use? We are happy to open Accounts for new Commercial Customers, subject to the normal checks. Unfortunately, we do not open accounts for the domestic market, with the exception of 'Landlord's'.
  • Will installing Double Glazing instead of the single glazing I have at present cure condensation problems inside my windows? Condensation is a ventilation issue and will not be cured purely by installing double glazing. However, it will be reduced. Heating & ventilation play a large part.
  • Can I obtain samples of products? Yes. We can supply samples of all products, Mirrors - Painted Panels - Units etc. However Non-Account customers are charged a small Fee of £8.25+ VAT per sample to cover our costs, which are refundable against any order placed. Make your request to or use our contact page.
  • Where can I find a glass supplier near me? We cover a wide area of Kent and London. Contact us to find out if we supply and fit glass in your area. Make your request to or use our contact page.
