FREQUENTLY ASKED QUESTIONS

Do you have questions about what we do or how we do it? The products we use? How we will operate on the day of install? We have tried to answer as many questions as we can below. If there is anything more that you would like to know that has not been answered within this frequently asked questions page then feel free to contact us by phone or email and will be happy to answer any other questions.

Why do I need foam insulation?

There are a number of benefits to installing foam insulation in your home. The primary benefits are that it can; improve EPC rating, save on energy costs, reduce airborne noise pollution, improve air quality and moisture management and reduce cold air crossing to the inside living space. All of these come together to improve living or working conditions.

How long will the process take to complete? Can I use the property while the process is taking place?

The process can take 1-2 days depending on the complexity of the job. If you are visited by one of our surveyors they will give you an estimate based on the area that needs to be covered.

The property can be used while the process is underway, there will be traces of chemical fumes due to the products being used. However we endeavour to ventilate the work area as best as possible and keep the process as non intrusive as it can be.

How much will it cost to install foam insulation?

We cant give a fixed price, we do offer a service where a surveyor would visit the property take measurements and provide a personalised quote to you on the day. Our surveyors are also happy to take you through any details you would like to confirm while they are there with you.

Does the foam insulation pose a fire hazard?

The foam insulation is graded to class 1 fire rating when tested to BS 476 Part 7.

Once the foam insulation is installed can alterations be made to the roof/structure?

Yes alterations can be made. Open cell products are very easily modified and removed, it is a lighter consistency than closed cell. Closed cell can often be used as a bonding agent and can be more difficult to alter and remove but it is still possible. You should always ask for help when attempting to alter or remove foam insulation if you are unsure.

The process that we use does not involve bonding directly to the roof tiles as many installers have done in the past, we will always install a layer between the tiles and the foam so as roof repairs and alterations can be undertaken as normal.

I am concerned about moisture being trapped and causing damp, mould or rot in my timbers. Will this happen and how can it be avoided?

No, both open and closed cell products provided by FoamInstall are breathable. We also will install a layer to allow for the roof to breath properly.

How does the application process work? 

Foam insulation is projected from our high tech foam applicators releasing a combination of two substances that blend together at the nozzle and immediately begin an exothermic reaction, settling on the surface and expanding after a few seconds to create the foamy substance. The foam fills the space and creates an air-tight seal, it then hardens over a period of 2-5 minutes and after 1 hour the substance will have cured and have a hardened outer layer.

What is the foam insulation made of? Is it environmentally safe?

The foam insulation is made up of two components that are mixed together to create an exothermic reaction. These components can differ between suppliers of the compounds. Generally the compounds consist of a bonding agent and a resin.

Yes the compounds are environmentally safe. The products are tested and rated by suppliers and show an extremely low Global Warming Potential and no Ozone Depletion Potential.

What is the difference between open and closed cell foam insulation?

Open cell is a lighter foam, with an R-Value of 3-3.5 per inch. Closed cell is a denser foam, with an R-value of 6-7 per inch.
