What is single ply construction?
What is single ply construction?
Single-ply Roofing Systems for Commercial Applications. Specifying a roofing material for low-sloped roofs traditionally meant built-up roofing (BUR) and using asphalt or coal tar. Recently though, variations on single-ply roofing membranes have dominated the market.
What is a mechanically fastened roof?
Mechanically fastened roofs attach primarily with screws and metal plates rather than glue. Offered in standard roll goods, mechanically fastened roofing systems work well in places where a high wind uplift performance is required.
What is single ply waterproofing?
Single ply is a flat, synthetic polymer based roofing material that, as the name suggests, provides a waterproofing layer in a single sheet. Usually supplied in rolls, the material is either entirely homogeneous or contains a reinforcement layer.
What is thermoplastic single ply roofing?
Single-ply roofing systems utilize flexible sheets of thermoset or thermoplastic membranes. Both membranes offer unique advantages and disadvantages. For example, thermoplastics are highly reusable as they can undergo melting numerous times, while thermosets remain in a solid state after curing.
How thick is a single ply membrane?
The thickness of single ply membrane is in the range 1.1mm to +2mm. Some products are homogenous, others are reinforced with glass fibre or polyester, depending on the application. Membranes are sealed at joints to form continuous waterproofing.
What does mechanically fixed mean?
Well, as simple as it sounds, a mechanically fixed single ply roof system is a roof system that is held in place using mechanical fastenings. These secure the single ply membrane, over the top of the insulation and vapour control layer, and are fastened in place to the roof deck.
What is the life expectancy of a TPO roof?
15 to 20 years
A TPO roof membrane can last anywhere from 15 to 20 years. It is a single ply reflective roofing option, and it is typically adhered or mechanically attached. This membrane can be left exposed throughout its life.
What types of single ply roofing membranes are available?
The three main types of compounds used in single-ply membrane systems are:
- Ethylene propylene diene terpolymer (EPDM): a thermoset.
- Polyvinyl chloride or polymerized vinyl chloride (PVC): a thermoplastic.
- Thermoplastic polyolefin (TPO): a thermoplastic.
What is a mechanically fixed single ply roof system?
Well, as simple as it sounds, a mechanically fixed single ply roof system is a roof system that is held in place using mechanical fastenings. These secure the single ply membrane, over the top of the insulation and vapour control layer, and are fastened in place to the roof deck.
Can a single ply roof membrane be replaced?
Easy to replace- If in the unlikely event, the single ply membrane ever does rip or break, because it is only held in place with fasteners, it can be easily removed and replaced by swapping like for like. This can be more complicated for a green or sedum roof, or a fully adhered roof.
Are single ply membranes recyclable?
Recyclable- Because the single ply membrane doesn’t come into contact with any chemicals, or adhesive, at the end of it’s life span it can be recycled. As a business or company, this can help you achieve your own company targets, and those from the Government, in terms of green credentials, and environmentally friendly construction.
