How is spray foam different from traditional insulation?
Spray foam insulation provides higher R value in addition to better air sealing. Certain types of foam, such as closed cell foam, serves as a vapor barrier and adds structural stability as well. Unlike traditional insulation, foam will never settle causing your insulation to be less effective.
What is the difference between "closed" cell and "open" cell?
Open cell foam is a softer, less dense foam which typically provides an R value of R4 for every inch thick. It is a great air barrier but is not a vapor barrier, therefore should not be used in areas with high moisture, such as below grade (crawlspace). It also should not be applied to concrete or masonry. Closed cell is more dense, provides an air and vapor barrier, while also providing structural stability. Closed cell foam typically has an R7 value for every inch thick it is sprayed.
What type of spray foam is best for my home and what if I have a roof leak?
The climate zone you're located in and the construction of your home would dictate which foam is best for you to use. If a roof leak occurs, the water will still find a way through the insulation, typically through wooden structural members, and once you see that, you should contact your roofing contractor for any necessary repairs. Spray foam will not be damaged from a water leak like traditional insulation. It will dry out and continue insulating as it did before, whereas traditional insulation would need to be replaced.
Should I have the attic floor or roof decking spray foamed?
The location of your HVAC unit and your duct work will determine which option is best.
Is spray foam insulation safe?
Spray foam is extremely safe and environmentally friendly. However, homeowners should not be present when it's being applied. That's why you'll see insulation crews always wearing proper PPE equipment while working. Homeowners should allow the foam to completelY cure after being sprayed and allow the home to vent for several hours before returning.
What about the "problems" with spray foam?
There are virtually no problems with spray foam. Some contractors believe that spray foam seals the house too much and doesn't allow the house to breath properly, however, we do not believe that. We believe in building it tight and venting is right. If more air circulation is needed, there are better ways to allow that than to purposely allow air see page with poor insulation and air sealing.
How long does it take to lift a concrete slab?
There are many variables involved in concrete lifting. The size of the slab, size of the void underneath the slab, what the initial issue was causing the collapse or sinking. Concrete lifts can take anywhere from 2 hours to 2 days depending on the job.
Will my landscaping be disturbed when my concrete is lifted?
landscaping should not be effected. Our employees are mindful of their surroundings and if they find themselves near landscaping, they take extra care not to disturb it. If there is a situation where this is a possibility, the customer will be made aware of this in advance.
Is the concrete lifting process noisy?
The only part of the concrete lifting process that may produce excessive noise is if concrete drilling is necessary. There will also be a generator running throughout the course of the job but that typically doesn't disturb neighbors.
