Toughened Glass – it’s the LAW!

Toughened Glass VS Standard Glass

Irish Building Standards LAW

Safety glazing should be provided to any glass in a “critical area”. Glass panels less then 250mm wide can be fitted with laminated glass. Whereas, glass panels wider then 250mm have to be fitted with toughened glass.

Below is an overview of critical areas that require safety glazing:

Any glazed area within a window below 800mm from floor level

Any glazed area within a window that is 300mm or less from a door and up to 1500mm from floor level

Within any glazed door up to 1500mm from floor level

For further info please refer to Document D “Materials and Workmanship (2013)” of the latest “Building Regulations”.


The red areas in illustration below show critical locations in terms of safety. Glazing areas numbered 2, 4, 5, 6, 7, 8 and
10 should be in accordance with the recommendations of BS 6262, Part 4.

Toughened Glass Areas

Here’s what you need to know about glazing for your log cabin.

Wondering what kind of glazing you need for your log cabin? Confused about window thickness, double or single glazing etc.? Don’t want to be sold something you don’t really need?

If you don’t want the wool pulled over your eyes, then rest easy. Here is a clear and concise guide to make sure you get what you need and more importantly, you don’t pay over the odds.

Here at, we like to give all the information you need so you can make an informed decision. You can use this information to shop around, to compare us with the rest of the market. If and when you are ready to go and want to do it right, come and talk to us.

Things to consider

  1. Is the cabin just for storage? If it is just for storage, standard 24mm cavity double glazing is just the job. All of our garden rooms come with these as standard.
  2. What about day use only? If just using for occasional day use, particularly during the summer, then our standard 24mm windows would again be sufficient for your needs. We would recommend in this case that you insulate the roof at this point. It will keep the cabin cool in the summer and not overheat like an uninsulated shed.
  3. Year-round day use? If you are going to use your cabin for day use all year round, you should seriously consider upgrading to Premium windows and doors. Our Premium range are 24mm cavity double glazing. They provide fantastic insulating properties. Roof insulation is required if you are using the cabin in the winter. You don’t want to be cold or have to endure higher than necessary heating bills, so installing Premium standard windows are recommended. At this specification, you will retain your heat for far longer, meaning lower heating bills throughout the lifetime of your cabin.
  4. How about residential use? Have you ever lived in a cold house? Resented spending a fortune on heating the sky due to poor insulation? For year-round residential use, you really need to go with roof, wall and floor insulation and Premium windows and doors. Whilst this may increase the initial outlay, the reductions you make in heating bills over the lifetime of your home will save you thousands of euro. In effect, you are future-proofing your monthly outgoings.

Don’t be oversold:

Nobody likes being sold something they don’t need. Here at, we will be the first to tell you what you don’t need. If you don’t need it, we won’t sell it to you.

By law, all glazing below 800mm from floor level and within 300mm of a door and up to 1500mm from the floor, must be of toughened glass. Regardless of their position, ALL our windows and doors use toughened glass.

With an increase in suppliers of log cabins in Ireland, how do you know who is genuine and who is not? Well here is a handy way to spot those who are not;

Ask them if their glazing uses toughened glass.

Toughened glass must have a seal etched into a corner of the glass. If they say it’s toughened glass, check their display models. If the etched seal is not visible, it is not toughened glass and the supplier is just telling you what you want to hear, not what you need to know. At this stage, you should walk away.
