TYPES OF SPRAY FOAM INSULATION
The best thing you could do for your family and your home is getting your house insulated. From lowering the energy usage to enhancing the structural integrity of your walls and roofs, insulation will make your home energy-efficient, comfortable and a healthy space conducive to your wellbeing.
When it comes to SPF or spray foam insulation, there are essentially two types- Open Cell Foam and Closed Cell Foam. Understanding the difference between the two will help you understand which type of SPF will suit your needs better.
How long does External Wall Insulation (EWI) last?
Spray foam insulation of external walls is known to last for decades, typically from 30 years to longer.
Does EWI prevent dampness?
Yes the effects of condensation can be diminished with an efficient EWI system. This is because the masonry bricks are kept warm by the external insulation, preventing condensation.
Does EWI prevent dampness and mold?
EWI ensures that condensation is mitigated. This also prevents the dampening of internal walls and the formation of mold. However, care should be taken to check if the walls are thoroughly dry, prior to installation.
Can EWI improve the U-value of my property?
Since efficient EWI systems significantly reduce the energy consumption through increased thermal efficiency or energy conservation, a well installed EWI system converts to an improvement in a property’s U-value.
Can I install an exterior wall insulation myself?
Yes, you could and installing EWI yourself might help you save the money you might otherwise spend on hiring a firm for the job. However, it is not recommended since a poorly done job might result in major problems and more expenses down the line. To ensure an efficient installation, it is worth hiring the services of an experienced firm or insulation contractor.
Will I feel the effects of the EWI instantly?
Yes- the effects are almost immediate. You will no longer feel the need to heat up your home frequently or for as long as would prior to the insulation. You will also get the benefits of sound insulation since an effective EWI blocks the sound of the outdoors and keeps it from coming indoors.
Is there an ideal time to get an EWI done?
While there is no good time or bad time to insulate the exterior walls, it will be convenient for you to do it while undertaking other major exterior home repairs and renovations.
