What is Spray Foam Insulation?

Spray foam is an insulation product that comprises of two compounds. These compounds are blown through hoses that meet at the spray gun combining the compounds into a single composite as they are sprayed onto the underside of the roof lining, felt, paper, boards etc, between the rafters.

After the reaction has completed the spray foam insulation cures and sets creating an air tight barrier Attachments area.

Frequent Asked Questions!


Why Is Spray Foam Insulation Better than Traditional Insulation?

Spray foam insulation is the perfect alternative to traditional insulation methods such as fibreglass. Lapolla spray foam insulation stops conditioned air escaping your home, and stops air passing through your home, whereas fibreglass allows the air to pass through, and only slows down heat loss.

Spray foam insulation expands up to 100 times its original size to fill every crack and corner of your home for superior thermal insulation and air sealing compared to fibreglass which cannot fill all the spaces and gaps, that results in enough air leakage every day.

Spray foam insulation lasts the lifetime of your home and comes with a 25-year manufacturers warranty, whereas fibreglass needs an upgrade every 5 - 10 years.

Will Spray Foam Insulation Rot My Timbers?

No. Our open celled foam is breathable, when applied to any surface it allows any moisture present to dry out through evaporation, this is important as timber and masonry surfaces need to breathe to ensure that no damp or rot problems are caused. Whereas a lot of the horror stories come from polyurethane closed cell foam, which is more suitable when moisture breathe-ability is not a requirement such as on metal. However, if your timbers are already damp or have some form of rot or woodworm they should be treated and dried first.

Lapolla insulation does not have food or organic value; therefore it isn't a suitable environment for pests and bacteria. Lapolla is a superior insulation system against mould, with an excellent protection factor compared to fibreglass and cellulose. Rodents and pests will stay away from it as well.


Open Cell

Open cell spray foam insulation is a soft breathable low density (Approximately 100mm thick) insulation prominently used when timber is involved and allows timbers to breathe, ideal for lofts, underfloor, walls, crawlspaces, and commercial however it can also be used on non-breathable surfaces such as metal.

Closed Cell

Where as closed-cell spray foam insulation is a rigid medium density (Approximately 50mm thick) insulation ideal for continuous insulation solutions and prominently used for metal, ships, containers, marines, shipping containers, industrial, and basements however it can also be used in properties as it adds wall racking strength, and structural integrity to the building.


More Facts about Spray Foam

Spray foams air sealing qualities help reduce the amount of dust, allergens and pollutants entering your home, in cofab fa-teamspeakmparison to fibreglass which allows allergens and pollutants to enter your home, these can trigger allergies as well as respiratory issues.

Lapolla

spray foam insulation contains no harmful chemicals, whereas most fibreglass contains formaldehyde and may emit formaldehyde fumes into your home.
