retrofit roof/attic insulation

why is it so important?

To help you make considerable savings on your energy bills, our team at JSJ can install one of the market leading open cell spray foam insulations.

As we all know heat rises. Your home loses up to 50% of air leakage through your roof. Even though you may already have loft insulation at ceiling level, due to it being air permeable, it will only retain a fraction of the heat generated compared to Icynene Spray Foam Insulation.

Insulating your loft thoroughly offers many benefits. It can increase the EPC efficiency of your home, make your home warmer in the winter and cooler in the summer, as well as significantly reducing your energy bills.

But first, let us explain how it works and why your current setup is not as efficient as it could be.

As warm air rises through your home, it escapes through your roof. This air needs to be replaced so cold air is pulled through your floor.

The reason why there are vents in your roof is to allow for air flow because without air flow, when the warm air in your house rises into the roof area and meets cold air, condensation would otherwise form. Any condensation is of course bad news, as overtime it will shorten the life span of your roof.

Letting warm air escape is a waste of energy and money but up until now, because air vents are paramount for ventilation, there was no other way of stopping your home from continually losing heat through these vents and your roof.

Fortunately, there is now a solution, and it’s the key to helping you significantly reduce your energy bills.

By applying Icynene Spray Foam Insulation to your loft space at rafter level, it super insulates your roof space so that what was previously cold air space will instead now be a similar temperature to the rest of your home, reducing the risk of condensation or mould.

Icynene Spray Foam Insulation is 100% open cell and breathable, which means that whilst it prevents a direct flow of air through it, it still allows any residual moisture in the air to pass through – just like a Gore-tex jacket – which further helps ensure there is never any build up of dampness.

The benefits don’t stop there either, as it virtually eliminates noise from Tvs, music systems and outside traffic. Icynene spray foam can reduce outside noise by up to 13db.

When sprayed in place Icynene expands completely filling all cavities and voids creating a sealed building envelope which eliminates air leakage/infiltration. Air leakage/infiltration accounts for up to 50% of heat loss from a building. Unlike other foams, Icynene’s unique polyicynene formulation is 100% water blown and therefore contains no harmful agents, volatile organic chemicals, HCFCs, HFAs, HFCs or formaldehyde. It has a Global Warming Potential (GWP) of 1 and an Ozone Depletion (ODP) of 0.

Icynene spray foam insulation

Icynene is the only foam on the market to have achieved BBA, ETA and BDA certifications and has been successfully tested and certified for applications directly to the underside of breathable and non-breathable roof membranes and felts. It has received BBA certification for this application. Icynene absorbs the lowest amount of moisture and has the highest level of vapour resistivity of any soft foam on the market.

Just as with any home improvement project, it is essential that the installer carrying out the work has been fully trained to do so, and they are fully accredited to give you the peace of mind that the job will be done correctly.

In addition, you also need to be sure that you have someone to turn to if, in the unlikely situation, a problem does arise. JSJ Foam Insulation are an approved Icynene installer and an accredited member of HICS Consumer Protection for the home improvement industry. We offer a 25 year warranty on our products and a two year guarantee on our install.

If you’d like to make significant savings on your energy bills and reduce noise levels, letting JSJ install Icynene Spray Foam Insulation could be the greatest money saving investment you make all year. At the same time, you’ll be doing your bit for the environment by helping reduce the CO2 emissions through using less energy for many years to come.
