There have been several fairly recent developments in dry lining boards for internal walls. Not to be confused with Planning consent (which is more to do with whether you can put up the building in the first place).

Take for example a traditional cavity wall which gets insulated using expanded polystyrene sheets and imagine that the sheets fit closely but have slight gaps because they were not cut perfectly or mortar snots hold them away from the inner leaf. If there is a solid ground floor with a DPMdamp proof membrane - a sheet of (usually) plastic used to prevent dampness rising up through a floor or in through an underground wall.

Sleeper wall. chemical treatment. The original reason for cavity walls was to prevent rain driving in through joints in the masonry (not to give insulation – they give hardly any). Bedrooms: For a family house where the possibility of additions exists, remember it is simpler to add a room during initial construction than to remodel or build an addition later. In other words, how draughty it might be. Partition walls can usually be removed or have doorways cut into them without effecting the stability of the house. ), they can form a protective finish against impact where there is no such surface behind they can give a decorative appearance they can cover external services such as wiring, timber (note that there are some quite complicated, vertical board on board, board on batten, batten on board, to provide a coating which was impermeable to driving rain, to provide a visual contrast with other areas of the wall surface such as brickwork, to improve the appearance of areas of cheap or poor walling such as low quality brickwork or blockwork, the mixture of the material was too strong in cement: render needs to have a weak mixture, the base wall structure would tend to move very slightly, often due to changing temperatures and this would cause the render to craze and let in water, impervious renders can prevent moisture from diffusing out of the wall and trap it inside. Plasterboard is low in thermal mass (and not so good for sound insulation unless it is filled with acoustic mineral fibre). Additionally, cavity wall insulation material can be injected/placed into the cavity. See Passivhaus for the UK branch of the organisation. Contact the local planning department at the council. a waterproof layer in a roof which acts as backup protection in case the main layer fails. Below is one way to avoid this problem by returning the insulation about a metre back up the internal wall.

Internal walls which connect with external ones will also need insulating on both sides for about a metre back from the external one. I have a 60s house with solid wall and plasterboard dry lining on wood battens. Another way is to cut a vertical gap (of say 20 to 30 cm) between the internal and external walls where they meet.

There are now standard fan pressure tests to check how air tight a house is and the Building Regulations have minimum standards for all new houses (L1A – Conservation of fuel and power in new dwellings (England)). solid concrete floors which rest on the ground, inserting a physical barrier such as a polythene DPC or lead sheet. Plasterboard can achieve high fire resistance if extra layers are added. C – Site preparation and resistance to contaminants and moisture, G – Sanitation, hot water safety and water efficiency, J – Combustion appliances and fuel storage systems, K – Protection from falling, collision and impact, L1A – Conservation of fuel and power in new dwellings, L1B – Conservation of fuel and power in existing dwellings, M – access to and use of buildings (England), R – Physical infrastructure for high speed electronic communications networks (England), Timber frame kit house to Passivhaus standard, A measure of how leaky a building is to air.

BecoWallform – Insulated Concrete Formwork. Party walls are covered in the Building Regulations. Also known as a cold bridge. While some outer surfaces are designed to be totally water resistant (such as roof coverings) many other areas can absorb water quite readily e.g.-. It can be useful for levelling out the peaks and troughs of temperature within a house. Cavity wall construction was introduced as early as 1900 in some areas but predominates from 1935 to the present day. Concrete is an ideal material to support these loads.

The beams go directly into the concrete foundation. Solid External Masonry Wall. Rodents spend a lot of time gnawing in order to keep their teeth in good condition.They may destroy polythene vapour barriers (which can then cause condensation and damp) and may gnaw through plastic plumbing pipes if they encounter them. Prefabs (prefabricated houses) were a major part of the delivery plan to address the United Kingdom's post–Second World War housing shortage.

This kind of wall will often be perpendicular to floor joists or ridge. In this type of construction, the floors, roofs and the beams are supported by the load-bearing walls. Cavity Wall Construction. When an exterior wall ignites, the fire can spread to the roof, windows, doors, and other building components resulting in substantial damage or total loss of the structure.The resistance of exterior walls to burning and decay is directly related to the material used and the amount of fire ignition components in the surrounding areas.

This kind of detailing takes quite a bit of thinking through because of the changing courses of brickwork and how the flashings relate to the roof tiles or slates etc. Made in Germany. Thermal massthis is about how much heat something can absorb - so it involves its specific heat capacity and its volume. See also: Headwall. External wall insulation is not straight forward. Rain screens can be quite thin and this is an advantage if the thickness of a wall is becoming a problem due to the large amount of insulation being used. See below.

Cavity walls in general offer much better insulation as water cannot so easily seep through and the air pocket acts as an additional insulation layer. The reverse also happens so these materials will effectively have a higher thermal mass than normal and can be used to store heat as they are warming up and release it as they cool down, This keeps them at a more stable temperature. In the UK we are generally used to masonry walls with very few penetrations. There is a picture of such a junction at Under the Sun. This usually works quite well on plain brick walling but may not be effective in stone walls, particularly those which are thick, randomly coursed or have rubble infill because the chemical doesn’t reach the places it needs to.
