Frequently Asked Questions

Polyurethane is a plastic material which exists in various forms. It can be tailored to be either rigid or flexible. Tate’s Coating Services focuses on using polyurethane foams and elastomers. This includes the mixing of two chemicals and then the foam or elastomer can be spray applied or injected to suit many needs. For further information –

Spray foam insulation is a cellular plastic form of insulation. It is a method of insulating and air sealing using a spray applied application. The foam sprays on as a liquid directly from the gun and quickly begins to expand to fill and seal the cavity or surface.

At Tate’s Coating Services our polyurethane foam insulation systems are spray-applied using two-component products. The A-side component is an isocyanate and the B-side component is a resin. It is not a wet application, so no water is used. During the application, a chemical reaction takes place between the two components, creating a bond to the substrate as it foams up. It dries, cures and hardens within 3 to 5 seconds depending on the materials used and the job scope. This product should always be installed by an experienced applicator.

Polyurethane foam insulates and air seals in one step, which traditional insulating products do not do. Traditional insulations can also leave gaps around trusses, light fixtures, and any other building details which compromises performance. Polyurethane on the other hand fits perfectly around all detailing to provide a complete air seal.

Most of the damaging moisture within a building envelope is the result of air movement through the cavities. When warm air meets a cold surface within a cavity, it condenses and if not found in time, it can lead to mould and rot. Polyurethane foam creates continuously insulated walls and ceilings – exactly the leak-free building environment that is needed to minimise the potential for moisture, condensation and mould.

Yes. Polyurethane foam can also help with:

  • Noise reduction – Thanks to the sound-dampening qualities of polyurethane foam insulation, problems and annoyances related to “thin walls” can be easily be eliminated.
  • Access and repair – Unlike traditional insulation types, polyurethane foam insulation can be easily cut away and removed to access plumbing and electrical wiring for repairs.

During the application of polyurethane spray foam, the chemical reaction does give off a slight odour however given ventilation, this dissipates in a short time. Once the foam has finished reacting it becomes inert and no off-gassing, odours or smells are present.

Yes, polyurethane foam has been accredited to meet building standards. At Tate’s Coating Services, we have information available on request stating the fire properties of polyurethane foams as well as any other relevant information on the product requested.

Polyurethane spray foam insulation will last up to the lifetime of your home, generally 30 to 50 years. Unlike other materials and traditional insulation types, polyurethane foam does not sag or deteriorate over time. It may change colour during its lifetime due to UV light however if the foam is protected it will last for decades.

Open-cell foam is a soft flexible, water-blown foam with a high expansion. Once sprayed, low-density open-cell foam can be easily trimmed. It also permits bi-directional drying and has low ozone depletion potential (ODP) making it an environmentally friendly and sustainable insulation option.

Closed-cell foam is a hard rigid foam with more controlled expansion and typically a little more difficult to trim. Closed-cell provides a higher R-value per 25mm, meaning it has greater insulating power. Closed-cell foam can add structural integrity to a building while also providing an effective barrier to vapour and bulk water.

Both open-cell and closed-cell foam have different advantages so it’s not as simple as choosing “one or the other”. The best foam to be used in each situation is dependent on several factors such as design objectives, application, available space, needed R-value and costs.

Return on investment varies from region to region. However typically, homeowners who upgrade from traditional insulating products to polyurethane foam experience a 30 to 50% reduction in energy costs.

Polyurethane foam insulation enables efficient heating and cooling of a building which in turn reduces greenhouse gas emissions. 100% water-blown options such as open-cell polyurethane spray foam offer the lowest global warming potential and ozone depletion potential (ODP). Polyurethane also improves indoor air quality with no off-gassing.

Polyurethane foam insulation can help by keeping insects as it seals all the cracks into your home. It does not repel or keep burrowing insects such as termites tunnelling to get to food sources; however, the foam is not a food source itself. In heavily infested areas insects can tunnel and use the foam as a shelter. In these cases, standard pest control methods should be followed.

No. Polyurethane insulation is NOT urea-formaldehyde foam insulation. There is no added formaldehyde in the polyurethane foam insulation used today.
