![]() Infrared non-contact surface temperature measurements at walls can be carried out quickly and easily the dew point temperature is automatically determined at the same time. ![]() ![]() Used for private purposes or commercially – the high-quality pyrometer dew point scanner BP25 provides you with the opportunity to check surfaces such as interior walls and facades for cold spots with a high mould growth potential. If condensate forms frequently at the same spot, it usually doesn't take long until mould grows as well.

It has been proven conclusively that CI is the most effective way to insulate a building. In this way, any moisture that gets into the wall during construction, or by leakage, now has a pathway to dryness. Using CI also allows the temperature in the wall cavity to rise, which promotes drying towards the interior-the humidity controlled side of the wall. This can help the exterior wall assembly and building be more thermally efficient than with the 2圆 method and keep moisture out of the wall assembly. When the sheathing is enhanced or replaced by rigid foam continuous insulation (CI), the interior wall cavity is kept at a more consistent, warmer temperature in cold climates that can effectively reduce the threat of condensation.īy adjusting the amount of foam on an exterior wall, the builder can move the dew point to occur inside the foam, where condensation cannot take place. Continuous InsulationĪ continuous layer of insulation, usually installed outboard of a building, eliminates the issue of the insulation shifting and settling, while helping manage potential issues with condensation. There has to be a wall assembly form that can prevent moisture intrusion without sacrificing thermal performance. It can still prove costly to heat and cool the house. It can shift and settle over time, creating uneven (and thus ineffective) insulation. Builders today know that old method can create insulation issues since the batt insulation used in this type of wall assembly is often not installed correctly. To increase thermal efficiency, 2圆 wall construction has been used off and on for years. This phenomenon also occurs in hotter climates when warm, humid air comes in contact with cooler, interior surfaces.Ĭontrolling the interior wall cavity and exterior sheathing temperature can effectively manage condensation in wall assemblies. If the sheathing is below the dew point, determined by humidity levels and air temperature, condensation will occur on the inside, putting the sheathing, studs, and the wall insulation at risk of water damage. In cold climates, the inside surface of wall sheathing (which has very little insulating value) comes into contact with warm, moist air from inside a building. A Common WetĬondensation occurs when the temperature of a surface falls below the dew point. Once that is known, the choice must then be made to select the most effective form of wall insulation. The best way to prepare is to have an understanding of how moisture can develop in a wall assembly. Without a method to dry out, it’s only a matter of time before this can lead to mold, mildew, peeling paint, or worse.īecause we don’t live in an ideal world, we have to take time to provide dry conditions before a project begins, while making plans to manage moisture in the future. Walls can get wet, from the inside and the outside, and in some cases, they start out wet. However, in the real world this is rarely the case and installation can sometimes open the door to moisture entering. The materials would have minimal moisture and the weather would be perfect with low humidity during construction. In an ideal world, every wall assembly would be dry from the day it is built. Whether it’s new construction or a renovation, managing moisture content of the building materials from which the building is made must take high priority. The damage can be minor if caught early, but can also be so severe as to require completely gutting a building's interior.Įxpensive property damage and hazardous health conditions are two serious reasons to ensure all exterior wall assemblies are constructed in a way that will prevent or manage any moisture intrusion. ![]() If moisture is allowed to enter the spaces between the exterior and interior walls, every element, all the contents, and even occupants, are put at risk. It is extremely essential to manage moisture in an exterior wall assembly to protect your building from possible damage.
