- What Is polyurethane?
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 in-cludes the mixing of two chemicals and then the foam or elastomer can be spray applied or inject-ed to suit many needs.

- What is Spray Foam Insulation?
spray foam insulation is a cellular plastic and the 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.
- Why is polyurethane insulation better than traditional types of insulation?
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, basically anything, com-promising performance. However polyurethane fits perfectly around all detailing to provide a com-plete air seal.
- Can polyurethane foam help control moisture build up?
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 envelope that is needed to minimise the potential for moisture, con-densation and mould.
- Can polyurethane foam help address other issues?
Noise Reduction – It can also help reduce the transfer of noise. thanks to the sound dampening qualities of polyurethane foam insulation, problems and annoyances related to “thin walls” can be easily turned into greater privacy.
Access/Repair – Polyurethane foam insulation can be easily cut away and removed to access plumbing and electrical wiring.
- Is there an odour?
During the application of polyurethane foam the chemical reaction does give off a slight odour however given ventilation it will take minimal time to dissipate. Once the foam has finished reacting it becomes inert and has no off gassing or odours present.
- Has Polyurethane foam been tested for fire safety?
Yes. Polyurethane foam has been accredited to meet building standards and we supply the infor-mation available on request stating polyurethane foams fire properties as well as other relevant in-formation on the product requested.
- How long will the foam last?
Polyurethane foam will last up to the lifetime of your home. unlike other materials polyurethane foam does not sag or deteriorate over time. It may change colour over time due to UV light howev-er if the foam is protected it will last for decades.
- What is the difference between open cell and closed cell polyurethane foams?
Open cell foam is a soft flexible, water blown foam with a high expansion. Once sprayed, low den-sity open cell foam can be easily trimmed, permits bi-directional drying and has low ODP.
Closed cell foam is a hard rigid foam with a more controlled expansion and typically a little more difficult to trim. Closed cell provides a larger R-value per 25mm, can add structural integrity and can provide a barrier to vapour and bulk water.
- Which foam is better, open cell or closed cell foam?
Unfortunately this is not a simple as choosing “one or the other”. If you contact Tate’s Coating Ser-vice and explain the details of your intended insulation needs we will be able to provide you with the best options. 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.
- Is there any return on investment data related to polyurethane foam to traditional insulating products?
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 percent reduction in energy costs. It also out performs products like solar panels as it works 24hours/day.
- What are the environmental effects of polyurethane foam?
Polyurethane foam enables efficient heating and cooling to reduce greenhouse gas emissions. 100% water blown options available offer the lowest global warming potential. polyurethane also improves indoor air quality with no off-gassing.
- How does polyurethane foam perform against insects?
Polyurethane foam can help by keeping insects out by sealing 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 to use foam as a shel-ter and standard pest control methods should be followed.
- Does polyurethane contain volatile organic compounds (VOC’s) content?
- In the 1980’s, urea-formaldehyde foam insulation (UFFI) was used extensively. It was later found to off-gas formaldehyde gas. Is there any concern that the same could occur with this insulation?
No. Polyurethane insulation is NOT urea-formaldehyde foam insulation. There is no added formaldehyde in the polyurethane foam insulation used today.
- How are Polyurethane foams applied?
Our systems are spray-applied, two-component products that include an isocyanate (A-Side Com-ponent) and a resin (B-Side Component). It is not a wet application – no water is used. During appli-cation, there is a chemical reaction between the two components that creates a bond to the sub-strate as it foams up. It dries, cures and hardens as quick as 3-5 seconds depending on materials used and job scope. This product should always be installed by a experienced applicator.
