Different Types of Spray Foam

No! It's a misconception that all spray foam must be the same. There are a close cell and open cell spray insulation. At first, they may seem extremely similar but the differences are quite vast. Let's talk about some of them.

Open-cell spray foam is considerably less dense and spongier compared to the closed-cell. Due to its open cell, it will absorb moisture because of which it cannot give significant strength to the structure and cannot act as an air barrier material. They are prone to moisture absorption and is vapour permeable. Mostly it may require an additional vapour retarder and is not recommended for use below grade or flood-prone sites. 

On the other hand, closed-cell spray foam can be used in all climatic conditions and is the preferred choice for many air sealing and insulating tasks. This includes severe weather and air barrier systems. The closed-cell spray can add to structural virtue for enhanced performance during harsh weather times. It's widely used as a moisture control layer. Closed-cell spray foam is resistant to water and is considered a type two vapour retarder. It can meet for different barrier conditions namely thermal, moisture, vapour, and air. 

This allows significant design flexibility and is quite cost-efficient compared to the additional details and products required for an open-cell spray.  

The FEMA (federal emergency management agency) considers CC SPF to be flood damage-resistant – construction and insulating material and has approved it. 

So, know what glass wool heat insulation suits your purpose the best before purchasing it. 

Common Reasons of Roofing Problems

These are the common reasons for roofing problems.

  • Bad Weather Conditions – During weather conditions that are different, roofing systems undergo a few changes. Punctures that created by flying object along with high-speed winds, heavy snow loads, hailstorms lead to many problems to the roof. However, the most common and constant threat to the roof is the UV rays of the sun. UV rays of the sun cause more damage compared to weather changes and it becomes highly expensive during the time of repair.
  • Poor Insulation – When it comes to poor insulation, it takes time to show the causes. If there is a faulty insulation it leads to a ton of leaks. The leaks happen when proper work isn’t done which later causes interference during the use of the structure. Not only is the roof under stress but even the structural integrity of the building becomes at risk.
  • Lack of Maintenance and Inspections – 30years is the period a commercial roof can last. And during these 30years, if you ignore to maintain, deteriorations starts to take place. Therefore, it is important to constantly inspect the roofing problems because it is important. Not only will you increase the lifespan of the roof but also result in less cost.
  • Foot Traffic – Too much of foot traffic cause the roof to get damaged. Moreover, vent, skylight installations, HVAC units also get damaged if proper care isn’t taken. After a while, tears and rips start occurring leading to problems to the roofing system.

These are some of the causes of roofing problems. You can also follow similar reasons when it comes to installing glass wool wall insulation.
