There are many issues to consider with glass installation or repair including safety and security. This diagram shows the areas on doors, adjacent side panels, low level glazing and windows which are defined under current Building Regulations as critical areas, and where safety glazing must be used. These regulations apply to single, double and the new triple glazing.

Toughened or Laminated Safety Glass?

Safety glazing is achieved by using either toughened or laminated glass. All standard clear and obscure glass can be toughened but this takes a few days to manufacture. Both clear and obscure laminated glass doesn’t need to be processed, and can be fitted immediately, once cut to size.

Toughened Glass Explained

We have all seen the aftermath of a damaged phone box or bus shelter with little bits of ‘sugar’ everywhere. This is toughened glass in action. Without going all technical, the glass is processed using both a heating and cooling process. This gives the glass its strength making it much stronger on its surface. The only downside to using this in your home is that when it does get broken, all the bits tend to fall away and you are now left with a big hole where your window used to be. Great, if you tripped and you are not now going to hospital with life-threatening injuries, not so great at keeping unwelcome visitors out! However, if the toughened glass is in a double-glazing application, unless you have been very unlucky, you will have a second piece of glass to maintain security. But in single glazed applications, particularly on doors and low-level windows, laminated glass might be a better option.

Laminated Glass

Laminated glass will break like a car windscreen. Remember the TV films where someone head butts the windscreen and leaves a tell-tale ‘football’ impression? That is laminated glass. It will stay together as it’s bonded to a clear membrane. Although you still end up with damage, the ‘spiders web’ pattern means that your glass will stay in its frame and intruders stay outside! Laminated glass is standard glazing in shops and other business premises, but it is quite acceptable in door panels and other glazing applications in domestic properties too.  If you occupy a commercial property and you are unsure if the glass you have is the older plate glass or modern laminated safety glass, we offer what is termed a ‘Regulation 14 survey’. This will tell you which type of glass you have. But don’t worry! Even if we find some of the older glass (there’s still a lot of it around) you don’t have to have it replaced immediately. By simply having a clear safety film applied, your non-standard plate glass can be brought up to reasonable safety level and satisfy your obligations under current Health & Safety legislation. When it does eventually get broken, your new glass will be the laminated safety glass. Ring for details, and to book your Regulation 14 survey.

Manifestation Regulations

The manifestation of glass (visible marking) is a legal requirement in areas where there is a risk of human impact. – Workplace Health and Safety Welfare Approved Code of Practice L24 Regulation 14.The requirements are also incorporated in the Building Regulations BS6262 Part 4 Safety.

For a complete guide, please refer to the downladable leaflet in the Documents tab. We can supply and fit a wide range of manifestation to your glass. Even if we didn’t fit it. From simple dots to more complex corporate designs. Ring for details.

VELUX Windowsvelux window repairs by Acorn Glazing

If you have a misted-up unit or cracked VELUX unit, we can replace double glazed units throughout the entire VELUX range. Simply open your window and make a note of the identification number on the label. This is (usually) located on the front right hand side when the window is in the open position. Either give us a call or send this information via the ‘Contact Us’ form. We’ll give you a very competitive price for the work by return. Some of the replacement units are made up of standard glass. There are others that are made with toughened safety glass and this can take a few days to manufacturer, but we will tell you which, as well as a guide to how long they will take. Fitting can be done any time to suite you. Even at weekends.

We also supply and fit a wide range of replacement parts such as handles, keeps and locks.
