NVELOPE® Thermal Solutions

Optimised solutions, superior performance

To create the ideal thermal design for your project, you need to consider a number of key areas including: fire safety, thermal performance and heat loss, type and sustainability of materials, physical constraints, location and budget.

To get the ideal thermal solution for your project that balances all these key areas can be tricky. However, SFS Thermal Solutions makes this process much easier, operating across the wide range of NVELOPE® rainscreen subframe systems and utilises the proven technology of Project Builder Thermal to enable any project to be optimised for performance and budget. Whether a lower or a higher thermal performance is required our Thermal Solutions has the ability to fine tune your project requirements.
New call-to-action

Bridging the thermal performance gap

Utilising its UK Patent Pending technology SFS have been able to create a high performing solution that guards against thermal degradation due to compression of the thermal pad, ensuring no loss in thermal performance. This combined with the bracket material choice of Aluminium or Stainless Steel ensures that a full range of tailored solutions can be created for any project.

Features & Benefits

  • Assembly
    All systems from the Thermal Solutions range come pre-assembled to reduce the risk of incorrect installation helping to save you time on re-work or assembly on site.
  • Overlay and optimised cutting service
    NVELOPE Thermal Solutions further improves efficiencies through the overlay and optimised cutting service - reducing time and material waste on site by cutting rails to the specific lengths you need.
  • Full technical support
    As with all NVELOPE products we offer full technical support.
  • Warranty
    As with all NVELOPE products we offer an industry leading warranty.  
  • Project Builder solutions
    Project Builder is the leading software of its kind on the market today and is free to use. The software provides optimised system specifications and budget costing for your project, often within 24hrs. Project Builder makes specifying the right solution simple, providing a free project-specific PDF complete with: List pricing per M2, static calculations, NBS specification and thermal values.
  • Reduced performance gap
    Non-compressible insulation pad on the NVELOPE VB+Thermal, NVELOPE HB+Thermal and the NVELOPE NVS+Thermal products reduces the effects from thermal degradation due to compression of the insulating pad. This helps to reduce the performance gap from design to real world installation.

Finding the right solution for your project

Our solutions offer a range of thermal performances from good to exceptional, balanced against budget requirements. Supported by our Project Builder calculator, careful selection from the range can effectively reduce the thickness of insulation thereby reducing overall costs.

NVELOPE® VB & HB range fitted with plastic isolators

Aluminium brackets are supplied with a green plastic ‘isolator’. The isolator offers a degree of thermal benefit, but its principal function is to eliminate any potential galvanic corrosion between masonry and aluminium substrates.

NVELOPE® VB & HB + Thermal range

The thermal conductivity of aluminium means point thermal bridging heat losses through aluminium brackets are significant. The thermal pad not only works to counteract those heat losses, it is also utilises SFS’ unique technology that means the insulation is not compressed during installation of the bracket.


Made from 316 grade stainless steel, these brackets offer corrosion resistance in addition to a lower thermal conductivity. As a result, no isolator is required to separate the bracket from the substrate.

NVELOPE® NVS + Thermal range

The ‘ultimate’ solution for optimised thermal performance, the lower thermal conductivity
of stainless steel is combined with the non-compressible thermal pad to achieve lower external wall U-values.

Try Thermal Builder to find your thermal solution

U-values are the starting point when specifying thermal effects of the building envelope. Rainscreen subframe brackets are a potential  source for 'Thermal Bridging' or more accurately termed 'Thermal Point Loss' within a façade. 

To help identify the optimised solution, SFS have Project Builder and Thermal Builder which can support and offer guidance with regards to reducing the thermal impact by taking your project details and create specific ther­mal calculations. Based on your project’s unique wall build-up configuration, we can dynamically calculate the required subframe build up to achieve your target U-value. Try it here!
