Self-Adhering Vapour Permeable Membrane Is Mold Resistant

The self-adhering vapour permeable membrane can be applied to common substrates such as gypsum, oriented strand board (OSB), block, concrete, concrete masonry unit (CMU) and plywood.

IKO AquaBarrier VP Self-Adhering Vapour Permeable Membrane provides a primerless vapour permeable membrane solution with mold resistance for a variety of building envelope applications.

Self-Adhering, Versatile Applications
A self-adhering, primerless membrane, AquaBarrier VP, provides superior performance in wall assemblies where a vapour permeable, weather-resistive air barrier is required.

Thanks to the vapour permeable matrix of AquaBarrier VP, it is compatible and can be applied to common substrates such as gypsum, oriented strand board (OSB), block, concrete, concrete masonry unit (CMU) and plywood. The membrane is also designed for various applications, including masonry cavity walls, metal cladding systems, renovations and retrofits, siding, curtain walls and parapets.

The design of the AquaBarrier VP membrane allows for installation ease, with no mechanical attachments or primer required for standard application. Coated with a proprietary acrylic adhesive on the back surface, AquaBarrier VP offers performance for common wall applications and features a polypropylene release film to aid in removing the membrane.

AquaBarrier VP is an effective vapour permeable membrane when installed according to IKO specifications.

AquaBarrier VP is constructed of a polyolefin synthetic polymer (fibre) membrane with low water retention capacity and is therefore mold and mildew resistant.

The IKO AquaBarrier line includes a full range of membrane and accessory products that provide protection in wall assemblies with air and vapour barrier systems. Engineered to meet or exceed industry standards, the line includes self-adhering and torch-on wall membranes, through-wall flashing membrane, foundation protection and flashing tapes.

Roof Coating Reduces Energy and Maintenance Costs

Crystal roof coating helps reduce energy costs.

Crystal roof coating helps reduce energy costs.

Using white colored roofs is a way to help reduce heat gain into a building or home in the southern climates where it stays hot most of the time. Just as wearing white or light colored clothes can help you stay cooler on a sunny day, a white roof can help keep a building cooler and lower the load on the air conditioning unit, reducing cooling costs.

Using the cool roof calculator on Oak Ridge National Laboratory’s website, it shows that if you live in Miami, Florida a white “cool” roof can save you approximately 0.185 USD per square foot per year as compared to a black roof. That’s roughly $647.50 per year for a 3500-square-foot home or $9,250 per year for a 50,000-square-foot office building or warehouse.

But what happens when a white roof turns grey?

When doing energy saving calculations, one of the overlooked errors is not factoring in the loss of insulating performance when white roofs get dirty or moldy. When that happens, the “cool roof” impact is less effective because the roof has gone from a reflective white to a grey or green.

For concrete roof tiles, especially, another factor that impacts energy efficiency is moisture. When a roof is wet, it conducts more heat than when it’s dry, making it less energy efficient.  

That’s why Crystal clear insulating and mold resistant roof coating benefits all types of roofs, including white roofs. It not only has its own insulating benefit (in all seasons and climates), it also helps the roof stay clean and resists the growth of mold. Another benefit it provides is a moisture resistant surface, so rain beads up and rolls off (taking dirt along with it) rather than soaking in.

If you tally the stay clean/maintenance benefits (not the energy saving ones), you can estimate saving approximately 25 cents per square feet to have a roof power washed. For a 5,000-square-foot roof that is $1250 per washing, which is usually done every one to two years by most. Product for that same amount of roof, would be approximately $3,000, so with incorporating maintenance savings, payback would be approximately 2.4 years, and your total maintenance savings over the 10-year warranty period would be approximately $12,500 if you previously had to clean the roof each year.

A School Used Crystal Roof Coating to Keep their White Roof Clean & Efficient

A Florida school had a costly issue, their white metal roof grew mold and collected dirt, meaning not only constant maintenance costs to clean it, but also a loss of energy efficiency. They looked to Crystal roof coating to solve the issue and ran a 60-day trial to see how it would help them.

Crystal roof coating applied to a section of the school roof remained clean.

Crystal roof coating applied to a section of the school roof remained clean.

The roof was cleaned and a section of the roof was painted with a coat of white paint and then over-coated with two coats of Crystal clear insulating and mold and UV resistant roof coating.

The photo above was taken 60-days after application. The spots where Crystal was applied stayed clean and white, while the unprotected areas became dingy and less energy efficient once again.

Additionally, the coating provided thermal insulation to lower cooling costs, even when the sun wasn’t shining.
