Throughout its lifetime, the building has been under the influence of thermal and structural displacements, and it is also influenced by wind and water, all within a wide temperature range and various climatic conditions. Due to these stresses and movement, waterproofing insulation must meet certain requirements: it must be durable, flexible, waterproof and tear-resistant.

VI-PRO® EPDM membranes are ideal for sealing window joinery assembly from the inside and outside of the window. They are intended for both large and smaller areas, so they are perfect as damp insulation for larger industrial buildings or single-family houses.

CORRECT INSTALLATION OF EPDM MEMBRANES

In accordance with the provisions of the Technical Conditions to be met by buildings, as well as the current state of technical knowledge, it is known that the joints of windows with jambs should be made in a tight manner. The basic rule is “tighter inside than outside.” The need to use a highly airtight membrane results from the need to limit the flow of moisture from the building to the thermal insulation around the window, while any moisture present in this place should be able to “escape” to the outside. Due to this, there are two basic types of membranes for indoor and outdoor use.

From this point of view, the most important parameter of EPDM membranes is the diffusion resistance factor µ – also known as the water vapor transmission coefficient. Often the parameter Sd = (equivalent) diffusion air thickness is used to compare EPDM membranes. It determines the vapor permeability of a material by comparing its diffusive properties to that of a layer – the thicker it is, the more difficult water vapor passes through the air. Thus, the Sd coefficient determines the diffusion properties of a layer of building material of a given thickness by comparing them to the thickness of an air layer of the same diffusion resistance – therefore the dimension of this coefficient is a meter.

From this factor we are able to calculate the parameter Sd for any membrane thickness, Sd = µ x d.

Example 1. An EXT outer membrane with a thickness of 0.75 mm and µ = 32,000 will have an Sd = 32,000 * 0.00075 = 24m coefficient.

Example 2. An INT Super inner membrane with a thickness of 0.75 mm and µ = 300,000 will have an Sd = 300,000 * 0,00075 = 225 m.

As can be seen from the examples above, the water vapor permeability of the outer and inner membrane can be over 9 times higher for the same membrane thickness!

STRENGTH VI-PRO ® EPDM MEMBRANES

The strength and flexibility of the membranes remain unchanged for decades without any signs of shrinkage, melting, hardening or cracking. The membrane remains flexible at the temperature from –40 to + 120˚C. The service life of EPDM, defined as a minimum of 150% elongation at break, is over 50 years in exposed (outdoor) installations. EPDM and Butyl are also highly resistant to chemicals, attacks by rodents, fungi, bacteria and microorganisms. EPDM does not absorb water. EPDM and Butyl have the ability to compensate for thermal and structural movements of the substrate thanks to the linear elongation in the product plane, reaching 300% and over 100% in other directions and at all temperatures. Unlike many thermoplastic materials, EPDM does not have a clear yield point, deformed to the extreme, it will always return to its original shape, size and thickness.

ADVANTAGES OF VI-PRO® EPDM SYSTEM

• Resistance to weather conditions, pollution, UV radiation. The expected service life exceeds 50 years.
