Polyurethane spray is a modern insulation system. This type of modern foam insulation technology has been steadily expanding into the residential, industrial, & commercial sectors in Vancouver, surpassing the use of more conventional materials like cellulose in terms of popularity, reliability, and cost.
You might be surprised to learn how many sectors have benefited from this technology. Besides its useful application in the construction industry, polyurethane spray foam has secured its use in sectors such as maritime, aerospace, mining, transportation, etc.
Polyurethane spray in the Attic
Polyurethane spray is a popular choice for insulating attics due to its excellent thermal properties and ease of application. When used in the attic, polyurethane spray forms a continuous insulation layer that fills gaps, cracks, and crevices, providing an effective barrier against heat transfer.
By filling in the crevices & gaps with polyurethane spray foam, you can better regulate the temperature in the attic. Keep in mind that the walls and ceilings are the primary foci for foam insulation in the attic. Once these spots are sealed, look for missing places where air could be leaking in.
The “R” value
Polyurethane spray also offers other benefits for attic insulation. Its high R-value (thermal resistance) ensures superior insulation performance, even in thin layers. It can adhere to various surfaces, including wood, concrete, and metal, making it versatile for different attic structures.
A poorly insulated attic will be just as hot as the scorching sun in the summer, and in the winter, it will be cold enough to safely store frozen goods. The foam's expansion properties allow it to fill irregular shapes and hard-to-reach areas, ensuring comprehensive coverage and minimizing potential thermal bridging.
The ability to block sound
Polyurethane spray insulation helps to block sound by creating a dense and continuous foam barrier. The foam's composition and application method result in airtight and solid insulation, reducing sound transmission through walls, ceilings, and other surfaces.
The material absorbs and dissipates sound waves, reducing noise infiltration and improving acoustic insulation within the space. Polyurethane spray foam also acts as a barrier against moisture, preventing condensation and potential mold growth, which can be particularly important in attic spaces.
It is also useful in the basement
Polyurethane spray foam can be highly effective in basements as an insulation solution. It creates an airtight seal, reducing air leakage and preventing moisture infiltration, which is a common concern in basements. The high levels of moisture and mildew in the basement contribute to the worsening of respiratory conditions like asthma.
Because of its expanding nature, the foam may fill crannies and crevices, ensuring complete insulation. The risk of mold growth and moisture-related difficulties is reduced, energy efficiency is increased, and the indoor temperature is maintained.
The application of polyurethane spray foam
When applying polyurethane spray foam, the following steps are typically followed –
- Surface Preparation
The surface to be sprayed is thoroughly cleaned and prepared. This involves removing any dirt, dust, or loose debris that may interfere with adhesion.
- Mixing
The two components of the polyurethane spray, the A-side and B-side, are properly mixed. This is usually done using specialized equipment, ensuring the components are thoroughly blended.
- Spraying
The mixed foam is sprayed onto the target surface using a spray gun or applicator. The foam expands upon contact, quickly filling gaps and conforming to the shape of the surface.
- Application
The foam is applied in even layers, ensuring consistent thickness and coverage. The spray gun is moved in a systematic manner to ensure uniform application.
- Curing
The polyurethane spray undergoes a curing process, typically within a few minutes. During this time, it expands, hardens, and forms a solid, durable layer.
- Trimming & Shaping
Once the foam has cured, excess material is trimmed and shaped to achieve the desired final appearance and thickness. This may involve using cutting tools or sanding equipment.
- Finishing
After trimming, the surface in question may be further treated and/or coated as needed to enhance durability and appearance.
