Insulation for Agricultural Buildings

•  Weathershield meets all local and federal Canadian building code requirements.

•  It doesn’t break down over time; fibreglass has been shown to gradually lose its structure.

•  Due to being blown into place, it fills in the irregular cavities of a building and prevents air infiltration and convection.

•  Its relative density makes it better than all other insulators at soundproofing a home from outdoor noise.

•  It is vermin-proof, treated to resist mice, rats and insects.

•  Properly installed, it will prevent ice damming.

Dependability

•  Weathershield is fully effective in temperatures as low as -60ºC and keeps buildings cool in the summer.

•  It has presented no health risk in its four decades on the market.

•  The Weathershield formula is proven to resist and contain the growth of mould and mildew.

•  It thermally and acoustically outperforms fibreglass and spray-foam insulation.

•  It maintains a higher R-value (value of insulating quality) than the same volume of any other insulation.

•  Its fire-resistant properties mean that a building will burn slower than if no insulation were installed.

Guidelines

Weathershield is to be installed in accordance with the General Installation Guidelines for Weathershield Insulation. Weathershield requires no specific maintenance. For attic installations, it is recommended that the building owner periodically inspect the attic to ensure that access traffic has not displaced insulation, disturbed ventilation or permitted insulation to contact heat sources. We warrant Weathershield to meet published specifications provided it is properly installed. The applicator must warrant the particular installation. When installing, you have two typical options: installing it yourself or hiring a contractor. For advice on both, please visit the Contact Us page.

Read the Guidelines

If you would like a head start in knowing how much attic insulation you will need to achieve our recommended R-value of 40, feel free to use the reference below.

Easy steps for Attic Insulation

Weathershield is relatively light and easy to handle — it can simply be added over top of existing insulation. You can do it yourself or employ the services of a professional. It is best applied with a blowing machine but can be hand-poured with a rake in small applications. Machine application is usually recommended for maximum efficiency.

How to measure blown in insulation

Measure the thickness of your present insulation and use the R-value chart below to determine how much insulation you must add in order to have R-40.

Example

If your attic has 3″ of wood shavings, your present R-value is only about 6.9. To achieve R-40, you would need about R-33 (about 9″ of Weathershield) to be added.
