What is single ply waterproofing?

Single Ply is a complete roof system. It is created from strong and flexible membranes composed predominantly of synthetic polymer. Membranes are sealed at joints to form continuous waterproofing. When combined with insulation and continuous support, they form complete, durable roof systems.

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 single ply membrane made of?

synthetic polymer
Essentially, a single ply membrane roof is comprised of flexible sheets of synthetic polymer that can be divided into two main groups, thermoplastics and synthetic rubber.

What is mechanically fixed?

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 most common problem associated with a single ply membrane roof?

The most common problems include: Seam failure. Over time, single-ply membranes can shrink, become brittle, and lose elasticity. As a result, stress increases on the membrane’s seams, resulting in failure.

What is ply membrane?

Single-Ply Membranes are sheets of rubber and other synthetics that can be ballasted or chemically adhered to insulation to create a layer of protection for your commercial facility.

What is single membrane roofing?

The Basics. EPDM Roofing System. Single-Ply Membranes are sheets of rubber and other synthetics that can be ballasted or chemically adhered to insulation to create a layer of protection for your commercial facility.

Do ridge tiles have to be mechanically fixed?

All ridges and hips must be mechanically fixed if bedded with mortar or dry-fixed systems used. It is no longer sufficient to use mortar as the only means of fixing tiles and fittings to roofs.

Can you walk on single ply roofing?

Flat Roof Surfaces You Can Walk On Whether its BUR (Built-up Roofing), TPO (Thermoplastic polyolefin), Modified Bitumen, or Single Ply Roofing, your roofing professional can apply the right waterproofing membrane to make it possible to walk on.

What does single-ply membrane mean?

single-ply membrane (Noun) Roofing membranes that are field applied using just one layer of membrane material (either homogeneous or composite rather than multiple layers.

Is single ply more pure than multi?

Raw is not more pure than single ply and single ply is not more pure than multi ply. they are all just different. People are now benching more in single ply than double ply so this is no longer a fact.

What is PVC roofing membrane?

What Is PVC Roofing Membrane? This type of roofing material is made out of polyvinyl chloride, which is a type of plastic. The plasticizers in the roofing material make it flexible. PVC roofing comes as a single-ply roofing membrane, which means it rolls out to cover the roof in a sheet to create a skin-like coating. 1. Durable, Waterproof Construction
