Knowledge of building insulation needs is crucial to improving energy efficiency and making energy consumption more intelligent. Therefore, the best strategy is to design a shell with optimal thickness of insulation to get the most benefit at the lowest cost.

SPF: The Perfect Protective Layer

Polyurethane foam has over 35 years of history as a conservable roofing agent. Polyurethane foam provides excellent insulation for the structure, and utility bills can reflect the difference. 

Spray polyurethane foam (SPF) is used as insulation for 

  • building walls, 
  • temperature-controlled transport equipment, 
  • roofs, tanks, portable or temporary structures,
  • sealing of the walls of rooms, attics and roofs,
  • an air barrier in commercial, industrial and residential construction,
  • a multi-component, high-performance protective coating system and many other applications. 

Sprayed polyurethane foam (SPF) is a thick (usually 1-2 ”) coating that is applied with multi-component sprayers. The two liquids chemically crosslink and react immediately.

Foam expansion begins immediately – even before it reaches the surface. It only takes a few seconds to fully expand, with the expansion being 20 to 30 times greater than the volume of primary liquids. 

With external roofs and other exposed applications, SPF is ready in a few minutes for a protective/reflective top layer (acrylic, polyurea, polyaspartate, polyurethane, silicone). 

Spray polyurethane foam is an excellent component for roofing if it is covered with acrylic, polyurethane or silicone polymer topcoats. 

Often, one of these coating systems is covered with gravel to increase its durability. SPF not only provides excellent insulation but also creates a solid, seamless, fully sealed moisture and air barrier. 

Smaller HVAC systems (or existing ones that are used less frequently) can be used, which significantly reduces pollution, pollen and other environmental impacts.

  • 75% less expansion / contraction due to temperature fluctuations compared to conventional standard products. 
  • Air bubbles make SPF extremely energy-efficient – studies have shown that foam roofs often lead to energy savings of 30% or more compared to other roof systems. 
  • Another study by Oakridge National Laboratories found 50% lower cooling and heating costs. That’s 58% less in energy costs. 
  • Spray foam insulation achieved energy savings of 50% or more on average, unlike other types of insulation with an average saving rate of around 30%. 
  • Studies have shown that SPF walls made of OSB, plywood, light metal, vinyl sidewalls or plasterboard can stabilise by 75 to 200%. 
  • It should also be remembered that, despite the impressive dielectric properties of many specially made electrical strips, very few materials are always 100% non-conductive in the right circumstances. 
  • Heat losses from an uninsulated attic are about 20% of the energy needed to heat a typical home. In an average home, the floor area can be an important source of heat, which accounts for up to 10% of total energy loss. 
  • It is available in many formats, including 2-meter unlit pipes, long bundles, sheets, as well as a pre-crevice, self-sealing pipe that reduces installation time by up to 30%.
