For most houses install time usually takes one to two days, for larger projects this may be extended depending on the size of the area.
Spray foam insulation generally costs something similar to that of installed rigid board insulation. Consideration needs to be made though that spray foam insulation actually air-seals the building and helps eliminate energy robbing air leakage and the associated problems with moisture, mold and mildew and condensation.. When calculating the actual cost you need to consider the cost of heating your building over time, the ability to eliminate some building wraps, and eliminate a significant portion of the material and labor costs associated with an air-sealing approach.
Calculations based on in-situ performance and comfort value in addition to long-term savings in energy savings will keep on saving you money every year thereafter.
Spray foam insulation’s air sealing properties are the primary reason for its superior performance. Other traditional insulations, no matter how well installed, can allow the leakage of air. This leakage not only steals your heat but can create potential condensation issues resulting in mould and mildew.
Spray foam insulation allows a certain amount of flex. As the building expands and contracts it can maintain the seal throughout the lifetime of the building. This seal helps control moisture, heat loss, air movement and air quality.
It simplifies the construction process for the builder, and allows the design of unique shapes and structures. Soundproofing is another benefit that is quickly appreciated by absorbing or blocking outside noise and also internal noise such as TV’s, Stereos and little (or big) humans.
Breathability in construction refers to the movement of moisture and should not be confused with air movement. Products like timber and open cell spray foam will not allow air to pass through them but will allow moisture movement and are typically described as vapour open.
Breathability matters as it affects greatly your Indoor Air Quality and in turn human health. As we create more structures with airtight design in mind the issue becomes critical
Airtight design about ensuring that no unwanted air leakage occurs through the fabric of the building. The level of insulation you install is pointless without proper air tight controls.
Airtightness is not only about heat loss, it is also about the migration of moisture into the fabric of buildings, the potential for heat loss and issues with condensation.
Open-cell and closed-cell foam are both great insulators as they each provide an excellent thermal barrier and air barrier. How they differ is that closed-cell foam is waterproof and will not let water move through it. Open-cell foam will allow water to move through it and dry which is important if a roof leak occurs or if new timber is not fully dried.
Stud walls, roof pitch, attic floor, slab insulation, crawl spaces, corrugated steel and many more.
In new construction, it is installed after the windows, external doors and roof are in, the electrical and plumbing inspections are completed, and after any other electrical or mechanical system is installed. It is the last installation to take place before plasterboard is installed
In existing structures it is typically installed to any area that is humanly accessible.
Excellent results are achieved in using open cell spray foam insulation in the attic slowing or stopping the “chimney effect” – hot air rising creating air movement within a building.
