Why you should consider spray foam insulation.

  • Cut energy costs
  • Longer lifespan
  • Advanced heat retention
  • Eco-friendly

Residential, commercial, and industrial design professionals recognise spray foam insulation to be the most energy efficient, eco-friendly, and innovative technology available today, significantly better than traditional insulation methods such as mineral wool.

Our spray foam insulation is designed and tested to ensure that it endures and performs for the building’s lifespan.

Are you a homeowner looking for some advice?

We have more than 30 years’ experience in spray foam insulation. So, we can help homeowners navigate finding a mortgage, provide guidance on regulations and will help you find the lender that meets your needs. 

We have also recently participated in creating an Inspection Protocol guide for building professionals. 

  • Should I be worried about having Spray Foam insulation installed in my property?

    While we know that some customers have experienced challenges, there are thousands of installations taking place each year without issue, and homeowners are successfully selling or refinancing their properties. Benefit from the expertise of a trusted network of authorised installers for a professional installation and peace of mind.

  • How do I know that Spray Foam is installed to a high standard?

    Your spray foam may not have been installed to a high standard if you can see that your spray foam is uneven, sagging or there is damp or mould forming around the area of installation. If any of these instances occur, you should get in touch with us for assistance.

    All Huntsman spray foam is guaranteed to be installed to a high standard as we only work with authorised contractors, furthermore we offer a standard 25-year warranty on all our products for added peace of mind.

  • I already have Spray Foam insulation. Should I be worried about selling or getting a mortgage in future?

    Homeowners shouldn’t have any trouble selling, purchasing or refinancing their homes as long as their spray foam installations have been carried out by an authorised installer, adhering to installation best practice and providing full paperwork as required by the Spray Foam Insulation Inspection Protocol. If you can, we recommend that you check the paperwork which should have been provided with the installation to make sure that the installer was authorised. 

    This documentation can be very useful in providing peace of mind and should a problem arise at point of sale or refinancing to share with surveyors and/or lenders.

  • I'm selling my home - how do I know my surveyor knows about spray foam?

    Together with the professional bodies in our industry, we have developed an Inspection Protocol to educate surveyors on assessing a home with spray foam insulation. 

    Through a five-stage framework, the Inspection Protocol supports professionals to confidently assess pitched roof elements and determine an overall recommendation for the suitability of spray foam insulation as well as a methodology for surveyors to ensure proper installation of spray foam. This includes undertaking and recording observations of the roof structure, the spray foam insulation which is present and the loft space.

  • How do I know my surveyor is using the Inspection Protocol

    You can download the protocol below which can be passed onto your surveyor if they don't already have it. Part of the protocol also includes a homeowner pack, which we have always supplied to homeowners when HBS spray foam insulation is installed. This documents key evaluation measures prior to installation, including the condition of the roof and a hygrothermal evaluation, alongside details of the material installed and of the installer.

  • How long does spray foam insulation last?

    Spray foam insulation lasts anywhere between 80-100 years, which means that once you have it installed it will last a lifetime. The long lifespan of spray foam puts it way ahead of traditional insulation like fiberglass and cellulose, which have a lifespan of around 15-30 years.
