Replacing Your Asbestos Roofing with Insulated Panels
The use of asbestos in the building industry grew rapidly in the 19th century. This was because of its full-scale mining at the time. Also, asbestos has excellent fire and heat resistance, factors that may have promoted its use as well.
If you have an asbestos roof, it is a high time you planned to remove it because of the dangers it poses to your respiratory system and the risk of cancer and other diseases.
The removal of asbestos especially when the shingles are severely weathered, require professional abatement. There are specific regulations guiding the removal and disposal of asbestos that you must follow to the letter.
Insulated roof panels are best alternatives for asbestos. They are optimized for strength, water drainage, and walkability. Normally, when replacing asbestos with insulated panels, the contractor must ensure the panels are third-party validated for:
- Thermal performance
- Acoustic performance
- Fire safety
- Water penetration
- Environmental credentials
Insulated panels come in various thicknesses starting from as low as 40 mm all the way to 135 mm. The choice depends on your pre-assessed roofing needs.
When installing the panels, the contractor must check for the accuracy and squareness of the steelwork. Normally, manufacturers clearly state their guidelines on steelwork tolerances that contractors must follow.
For the smooth installation of the panels, the rafters and purlins must be accurately positioned. This is especially the case where more than one panel is used on a slope. The panels should butt up to each other and adequately supported. This ensures your roofing structure doesn’t have cold spots and achieves structural integrity.
The choice of fasteners is equally important in the installation. For one, they need to be backed up by a meaningful warranty and during installation, they must be drilled through the panel’s external skin.
One other aspect with fasteners is that the number used must withstand the wind loads for both the site and the building.
