_Why Insulation is Important for Your Basement
_
When insulating a strong concrete basement customers in the past had less positive experiences. There were some complaints about cracking due to thermal bridges. According to experts, shrinkage cracks are caused by stress due to temperature differences and drying of the concrete.
To have a strong concrete basement is one of the reasons to isolate the basement and finding a better solution for it is very important. The solution was found in a special coating with insulation for the walls and for the floor.
How useful is basement isolation?
To answer this question we must first be clear to what the basement wall framing will be used.
Is it for basement storage?
Basements naturally have an average temperature between 10 and 15 degrees (depending on groundwater, etc.). This is because the soil and groundwater to the basement is a fairly constant temperature. This means that the basement does not have to be kept frost free and a good cool room for storing food, paint, etc.
Isolating it works just the opposite. Chances are that the basement heats the heat of the space above the basement or by any existing electrical devices, making the cold storage functionality lost.
To fully take advantage of the cool basement space, this course is placed outside the thermal envelope of the house.
Basement Utilization
An application of the basement to user space is generally the same as living in the rest of the house. The basement will be heated and then is also useful to isolate the basement. Otherwise, costly energy is wasted!
The basement is fully within the thermal envelope and placed no need to be closed by a hatch or door.
Considerations for application of insulation:
Provide individually controlled heating. In summer, the house often requires no heat, but the basement does.
The risk of condensation is smaller, but it can still occur. At a high humidity outside, the walls and / or damp floor is affected so we need to take this into account when ventilating. They could be absorbed by an electric dehumidifier to post.
Make a traditional suspension for the foundation beams to be well insulated. This prevents cold toe bridge and possible temperature differences in the basement wall (probability of cracking increases).
Application in the basement with a star connection, the dimensions of the space between the foundation beams is accurately followed as part of the space is taken up by adjusting the applied insulation. To isolate will enable the sides of the connection bar basement foundation insulation a thickness of 50 mm.
The XPS insulation boards can be slightly influenced by the temperature during application shrink. This has no significant adverse effects on the insulation and this is partly due to the design of the plates.
When a basement included in a building application is unnamed space utilization is instead used as a result of the building will not only be requirements on the insulation, but also for other issues such as accessibility, daylighting and ceiling height. Attention here is on the building permit.
As for execution, strong concrete has chosen a very solid structure of insulating high quality range materials.
Isolation is done with a standard 80 mm thick XPS / polystyrene plates. These boards have a very low water absorption and high compressive strength (300KN / m) and good insulation (λ = 0.035). Other thicknesses of insulation in consultation are of course possible.
Basements with Star Link cannot be fully provided with 80mm XPS associated with the maximum distance between the foundation and the basement bar. Two walls are then fitted with 50 mm thickness.
Strong basement wall framing gives 10 years guarantee of its waterproof insulation. As a result of stress and dehydration, it is possible that it cracks. This is unavoidable in traditional reinforced concrete. Cracking can occur without leakage and is not within the warranty.
