The promotion of modern gypsum-based plasters has led to the almost complete demise of lime plastering, and of many of the traditional skills associated with the craft. This has been exacerbated by the plastering trade being divided into flat and decorative work, with new ‘fibrous plasterwork’ being made in workshops.

Plasters are traditional surface finish materials in timber buildings. Today, the lack of fire performance data and design guidelines place such ecological materials at a disadvantage since plaster is not considered as a fire protection material for timber.

Do disused chimneys need venting?
Regulations tend to go for broad applicability and fail-safe options, so ventilating disused chimneys is the standard practice. One option is to install a ventilation brick in the outside wall of the house, so that the chimney is ventilated but with less of an obvious draught/heat loss issue.
Should I block up my chimney?
Plain and simple, DO NOT seal off a chimney or fireplace because you will get a flue full of condensation problems! Even when your fireplace is blocked off airtight you’ll still end up with “hidden” water issues. But these problems are only hidden for so long!
How do you stop a chimney draft?
Draught proofing chimneys with chimney balloons You can use a chimney balloon. A chimney balloon is essentially a balloon that you inflate in your chimney that creates a snug fit, thereby preventing hot air escaping up out of the chimney or cold air dropping down it, helping to prevent draughts in your home.
Why is cold air coming out of my fireplace?
Keep cold air out If your damper is warped, rusted or otherwise damaged, cold air in the upper flue is going to get past it. These devices are placed above the throat damper and inflated to completely block air from coming down into your fireplace. Balloons are designed to be used only when a fire isn’t burning.
Do fireplaces make house colder?
The standard fireplace is among the most inefficient heating devices you can operate. In fact, it can be so inefficient that in some cases it actually makes your house colder. And although many modern fireplaces use renewable fuel, they’re not considered completely “green,” because they can add to air pollution.
How do I stop the cold air coming in my fireplace?
Using a Fireplace Draft Stopper A fireplace is a huge source of drafts from the cold outdoors. A chimney can act as a wind tunnel even when the damper is closed, sucking cold air down into your home through the fireplace opening. A fireplace draft stopper is an efficient way to prevent this from happening.
Is damper open or closed?
A fireplace damper should always be kept open while the fire is burning. By leaving the damper open, heat is being lost as warm air is being pulled through a hole in your living room (the chimney) all the way up and through the roof. Pay close attention to the damper position, it’s very important.
Why is air blowing down my chimney?
Chimney Issues Obstructions in the chimney that restrict the flow of air can prevent an updraft from forming, and the result is that the fire smolders and belches smoke into the room. You may also get a backdraft if your chimney is too low — a larger flue size requires a taller chimney to produce a good updraft.
How do I stop my fireplace Backdraft?
Try opening a window near the fireplace to increase airflow into the home before opening the fireplace door. The area will be exposed to more air, allowing for less to be immediately taken through the chimney. Also, consider using a fan or turning on exhaust fans to troubleshoot this problem.
How can Backdraft be prevented?
Most of the time, this is accomplished by cutting an opening in the roof and refraining from opening any windows or doors on or below the fire floor until conditions have changed. This means that no search and rescue can occur and no water is being put on the fire until the vertical ventilation can be completed.
