Preventing Moisture Accumulation
There are three types of moisture that can damage walls. If you plan on building quality walls, then Ballytherm insulation is an ideal product. Ballytherm insulation is able to be used in most wall constructions, including internally lined solid walls and masonry cavity walls.
Ballytherm is committed to producing effective wall insulation products. One of the main concerns in building walls is preventing damage to the structure and preventing water from penetrating through the walls causing mould, which is a hazard to the occupants.
- Ground moisture
- Rain driven into the wall, which saturates the form.
- Water vapor that forms between the wall and insulation, as warm air moves out to the colder air.
In order to prohibit ground water from rising into the walls, they must have an efficient DPC, which should be attached to any DPM. By using pre-formed cavity trays and securing them to the Radon barrier in the cavity, a Radon barrier is secured – if laws require Radon proof buildings. A DPC and Radon barrier should not be set within the same mortar joint as there is a risk of creating a slip plane between the two.
The surface of the walls can be affected by the wind blowing rain, which penetrates into the building. Be aware of the surface finish, joint treatment and the position of the installation.
Thermal bridging can occur at meeting points (between walls and ceilings), at the location of penetrating fixings and at openings.
Address this as follows:
- Ballytherm insulation may be extended up between the rafters from the wall head to the lowest point of the roof insulation.
- At windows and doors, achieve better seals by locating openings behind reveals, meaning the insulation can come right up to frames.
- Use fixings made from stainless steel or plastic, with minimal sectional thickness to reduce the impact on the thermal properties of the insulation layer.
- With heating flues, use a pipe sleeve or combined-type flue to achieve the required 25mm spacing between flue and cavity wall insulation.
Where flues from boilers and other heating appliances penetrate the walls precautions must be taken to avoid the hot pipe coming into contact with the insulation. There should either be a 25mm gap between the insulation and the flue – provided by a pipe sleeve – or a combination flue should be specified.
