Spray foam insulation will stop the movement of conditioned air and warm air from escaping from your home or any building whether is a commercial or industrial property. Spray foam in a way acts like a wind breaker, where as fiberglass insulation works more like a sweater that you might wear. It will allow the passage of air but slows this movement of air down. This creates pockets of air that warm up and in turn by the time the air has passed through the fiberglass insulation it is no longer cold. This slowing down of the passage of air is call the Thermal Resistance of a product. The higher the thermal resistance the better the product will perform with maintaining a healthier temperature balance.<P>Spray foam insulation is constantly evolving to meet new and indeed future demands on building codes thus future proofing your home against the hot and cold climates. Whereby with current glasswool insulation and indeed Cellulose insulation it is more difficult for these products to keep up with the future demands of our building codes. The day will eventually come whereby the demand on glasswool will become less and less and there will be shift to more modern insulation products such as polyisocyanurate (PIR) and Spray Foam insulation's, as these products are capable of meeting the new demands from building code while also requiring less material thickness to do so.<P>One great advantage of using spray foam type insulation's is that it can expand to 100 times its original thickness. This is especially helpful in difficult to reach locations such as tight cavities, wall sockets and switches etc. When the insulation expands to its full capacity it is easy to cut away leaving a nice smooth finish for your drywall to go over. In some cases fitting fiberglass into these tight spaces can cause air leakage and also the compression of the insulation which will decrease its r-value considerably.<P>Its also worth noting that some spray foam insulation is completely waterproof and will repel water not allowing it to pass through whilst other spray foam insulation will allow moisture pass through it. Both insulation types have a positive and a negative so its important that you choose wisely for your job. Traditional fiberglass insulation will absorb moisture and this will damage the performance of the insulation considerably, so its important that if you do use fiberglass insulation that the area will always remain dry and moisture free. Mineral wool will not absorb moisture unlike fiberglass so if you have a high moisture area mineral wool is also a useful option.<P>Spray foam insulation once installed will never settle in the cavity or wall space unlike glass wool which can sag if not installed correctly. Its always a good idea if possible to check the condition of your glasswool insulation every 12 months and the best place to check is of course the top of your wall where the ceiling and wall junction meet. If your insulation has sagged in the cavity this will be the area where you will notice first as their will be a gap in this location. Generally a simple test of putting your hand onto the wall in this location and feel the temperature. In a cold climate if the insulation has sagged here you will instantly feel a cooling in temperature of the wall here vs 3 ft below. In a hot climate you will feel this area is much warmer than 3 ft below. Unfortunately if this is the case with your property its time to upgrade your insulation.<P>Traditional type insulation can when being installed cause alot of dust to go airborne during installation. This will settle down after a few days but can during the life of the insulation give off certain dust particles at a much lower level than during installation. In some case this can carry allergens and pollutants to enter the home. Where spray foam insulation will not give off any dust after installation and will create an airtight seal with your walls increasing the effectiveness of the insulation and also the quality of air within the building.<P>In many case alot of glasswool insulation will harbor rodents and insects for nesting and can be difficult to get rid off whereby spray foam insulation will not harbor such insects or rodents as the insulation is very strong and cannot be pushed out of the way by these insects and rodents to make room to move around. Spray foam will also not be a source a food for such pest and therefore is not an attractive place to live for them. Mineral wool is of the same make up while not providing a source of food nor a convenience place to nest.
