Suspended timber floors appeared in the UK in the early 18th century. Air flow was maintained between the ground and the timbers above by vents in the external walls, to ensure that the air did not become too damp. If you choose to create a modern floor with a slab cast over conventional insulation bats, it is important to choose the

The ground floor timbers are in a relatively poor condition. There are various previous repairs that have been carried out, with some sections of timber repair replaced. Some cut back and repaired and others treated. However, further softening and decay is evident throughout the construction.
I am about to embark on insulating under the suspended timber floor of my 1907 home. wires and bits of wood sticking out to get a good fit with celotex/kingspan . You need to work out the Perimeter/Area ratio of the ground floor to be able to evidence what the projected U-value will be.
Suspended ground floors Early forms. As mentioned above, the basic design principle for the early suspended floors was for timber joists to be raised above the ground normally being supported in some way by the external walls together with a series of sleeper walls or intermediate supports.
A suspended Floor is a specialist construction made of a solid concrete Floor, a system of sleeper walls and timber joists, upon which sits a supported timber floor. This type of floor allows home owners to run electrical wires and other such elements under the floor boards. Because the Floor is suspended above the ground, it should absorb less
Beam and Block Ground Floors The Most Popular Option. 1. Concrete block; 2. Outside wall; 3. Concrete block/ inner wall; 4. Sleeper wall; 5. Concrete beam The main dback with beam and block floors is that they are uneconomic below about 50m 2 so they are not a solution for small extensions.
Suspended concrete floors. In certain conditions the use of a ground bearing slab is not suitable. In these situations it is common to find a suspended concrete floor. In fact, nowadays, many developers prefer to use suspended concrete floors in all situations because of the perceived risks of ground bearing floors.
Many buildings with suspended timber floor suffer from rot and insect attack in the ground floor timbers due to poor sub floor ventilation. We look at this more thoroughly in our air bricks and air vents project , but quite simply if air bricks become blocked with debris or ground levels are raised this cuts off the air flow and water leaks may also occur.

Suspended slab subfloor. Tags: Floors. but can also be sat on top of pre-constructed walls to form a ground floor. What are suspended slabs made of? Suspended slabs are made of concrete and steel mesh, the same as a ground slab. They are normally pre-fabricated offsite, and transported by truck.
Suspended ground floors are also called hollow ground floors. A disadvantage of suspended timber floors used to be the decay caused by damp penetration. Modern construction methods ensure that the floor remains damp free and stable.
Purpose: Millions of properties have suspended timber ground floors globally, with around 10 million in the UK alone. However, it is unknown what the floor void conditions are, nor the effect of insulating such floors. Upgrading floors changes the void conditions, which might increase or decrease moisture build-up and mould and fungal growth.
Sub-floor ventilation. Many traditional properties are built with a suspended wooden floor which sits above a void air space between the perimeter walls and ground.If this space is not ventilated, the air in it becomes stagnant and humid, and the moisture within it begins to condense on the brickwork and flooring.
Concrete slab. In high rise buildings and skyscrapers, thinner, pre-cast concrete slabs are slung between the steel frames to form the floors and ceilings on each level. Cast in-situ slabs are used in high rise buildings and huge shopping complexes as well as houses. These in-situ slabs are cast on site using shutters and reinforced steel.
What's the difference between suspended and concrete floors, and how can you insulate them? Suspended floors vs solid floors June 6, 2017 We often get asked whether you should insulate floors between levels, as well as the ground floor. The answer to this is that it really depends on the reason for insulating.
Suspended concrete floors. There are occasions where due to the ground conditions that a suspended floor is needed rather than a ground bearing slab. These include soil with a low bearing capacity, sloping sites, soils containing aggressive chemicals and those with high water levels Marshall and Worthing, 2000 .
Different types of ground floor suspended flooring. Air bricks through the outer walls, facilitate air movement. In old properties 1910 to 1980 ish , air bricks were often fitted just in the outer brick skin with a brick left out in the inner skin, thus the air brick vented both under the floor and the wall cavity,
