HFC-245fa is the best replacement for HCFC 141b for blowing agents

6/4/2016

2 Comments

 
  • Enovate 245fa is a 0 ODP blowing agent
  • Compared to 141b, it has similar thermal conductivity and better mechanical properties
  • Unlike Cyclopentane, HFC-245fa is a NON flammable
  • Enovate 245fa foam has better thermal conductivity and improved dimensional stability compared to waterblown system.
  • This system is suitable for demanding spray applications

Benefits of Polyurethane Insulation

6/1/2016

0 Comments

 
Polyurethane insulation
  • keeps building cool. insulating the roof will make building interiors cooler and therefore more comfortable.
  • this will lessen the need for cooling and lower energy used for air-conditioning. This will help reduce climate change in the long run.
Polyurethane vs other insulation (R value per inch) 
  • Polyethylene foam                        3
  • Rock wool roll                                3 - 3.85
  • Polyurethane foam (sprayed)     5.5 - 6.5
Advantages of using PU
  • 1 inch of PU = 2 inches of other materials. Insulation will be thinner and therefore lightweight. This means that for roof applications, structural load will be less.
  • There are different applications like spray (on top of roof ), boards, or sandwich panels.
  • Rigid, closed cell PU is not affected by water vapor, and it maintains its form.
Disadvantages of using PU
  • PU foam is combustible but contains fire retardant and fire rated B2, which means it will self extinguish.
