G410-EL Adhered Roof System - Sarnavap 1000E

PVC-P single-ply roofing system for adhered warm roofs.

System includes:

  • Sarnafil G410-EL waterproof membrane.
  • SarnaTherm G insulation.
  • Sarnavap 1000E vapour control layer.

- Waterproof membrane:

Sarnafil G membranes are manufactured using a state of the art extrusion coating process that eliminates shrinkage and plastic memory and produces a dynamically stable membrane. In the coating process, a glass fibre carrier is coated on both sides with liquid Plastisol, prior to the application of a lacquer coating on the upper surface and laser marking of the membrane surface for identification. The unique lacquer coating eliminates the need for biocides, provides the membrane with an easy to clean surface and prolongs the life of the membrane by reducing plasticiser loss.

The process enables between 2% and 5% of recycled material to be used in the production of new membranes.

- Insulation:

Rigid polyisocyanurate foam insulation boards to BS 13166; with mineral tissue facing. Available in uniform thickness or tapered.

- Vapour control layer:

A 0.20 mm thick, polyethylene based, vapour control layer. Sarnavap 1000E is manufactured from low density polyethylene, blended to produce a vapour control layer that is flexible when cold, resistant to chemicals and ageing and rot proof. It is suitable for use in most mechanically fastened systems using both Sarnafil PVC and FPO membranes. Not suitable for high humidity applications or under green roofs.

Performance:

Certified by BBA, in their opinion, to have a "life expectancy in excess of 40 years" for exposed applications, with periodic maintenance as stated below.

"A planned maintenance cycle, including inspections by the Certificate holder at minimum intervals of five years, should be introduced if an extended service life is required. The Certificate holder can advise on methods of extending the service life. This could include the use of thicker membranes, specific maintenance requirements or localised replacement and repair."

Should the maintenance cycle not be followed Sarnafil G/S membranes have been given, by the BBA in their opinion, a life expectancy of "in excess of 35 years".

Installation:

- Waterproof membrane:

In adhered applications Sarnafil G410-EL is adhered directly to the substrate or a suitable thermal insulation board with Sarnacol 2170 or Sarnacol 2172 spray adhesive. Laps are then hot air welded to form seams which are stronger than the membrane itself.

Installation is carried out by Sarnafil trained contractors.

- Insulation:

SarnaTherm G can be attached to the substrate (deck or suitable vapour control layer) by mechanically fastening with SBT tubes and SBIW-70x70 pressure plates.

A vapour control layer will be required when SarnaTherm G is used.

- Vapour control layer:

Loose laid over any smooth surface with all side and end laps overlapped a minimum 80 mm, then sealed with Sarnavap jointing tape. At parapets and upstands, Sarnavap must be carried up to the upper edge of the thermal insulation and sealed to the upstand/ penetration with SarnaVap jointing tape, to form an airtight seal. When installed vertically, Sarnavap must be mechanically fastened along its top edge.

If the surface is rough, a layer of Sarnafil Type T should be used as cushioning layer.

The Certificate holder can advise on methods of extending the service life. This could include the use of thicker membranes, specific maintenance requirements or localised replacement and repair."

Should the maintenance cycle not be followed Sarnafil G/S membranes have been given, by the BBA in their opinion, a life expectancy of "in excess of 35 years".

Installation:

- Waterproof membrane:

Sarnafil G410-ELF is adhered directly to the substrate or a suitable thermal insulation board with either Sarnacol 2170, Sarnacol 2172 spray adhesive or Sarnacol 2142S. Laps are then hot air welded to form seams which are stronger than the membrane itself. Installation is carried out by Sarnafil trained contractors.

- Insulation:

SarnaTherm G can be attached to the substrate (deck or suitable vapour control layer) by mechanically fastening with SBT tubes and SBIW-70x70 pressure plates. A vapour control layer will be required when SarnaTherm G is used.

- Vapour control layer:

Loose laid over any smooth surface with all side and end laps overlapped a minimum 80 mm, then sealed with Sarnavap jointing tape. At parapets and upstands, Sarnavap must be carried up to the upper edge of the thermal insulation and sealed to the upstand/ penetration with SarnaVap jointing tape, to form an airtight seal. When installed vertically, Sarnavap must be mechanically fastened along its top edge.

If the surface is rough, a layer of Sarnafil Type T fleece should be used as cushioning layer.

G410-ELF Adhered Roof System - Sarnavap 5000E SA

PVC-P single-ply roofing system for adhered warm roofs.

System includes:

  • Sarnafil G410-ELF waterproof covering.
  • SarnaTherm G insulation.
  • Sarnavap 5000E SA vapour control layer.

- Waterproof membrane:

Sarnafil G membranes are manufactured using a state of the art extrusion coating process that eliminates shrinkage and plastic memory and produces a dynamically stable membrane. In the coating process, a glass fibre carrier is coated on both sides with liquid Plastisol, prior to the application of a lacquer coating on the upper surface and laser marking of the membrane surface for identification. The unique lacquer coating eliminates the need for biocides, provides the membrane with an easy to clean surface and prolongs the life of the membrane by reducing plasticiser loss.

The process enables between 2% and 5% of recycled material to be used in the production of new membranes.

- Insulation:

Rigid polyisocyanurate foam insulation boards to BS EN 13166; with mineral tissue facing. Available in uniform thickness or tapered.

- Vapour control layer:

A 0.60 mm thick, high-performance, self-adhesive vapour control layer, manufactured from polymer modified bitumen, with glass fibre reinforcement and aluminium foil top layer. Suitable for use in high humidity environments, green roofing systems, loose-laid ballasted warm roof systems and all adhered and mechanically fastened systems. Can be used as a temporary waterproof layer for up to 4 weeks, in strict accordance with the product data sheet.

Should the maintenance cycle not be followed Sarnafil G/S membranes have been given, by the BBA in their opinion, a life expectancy of "in excess of 35 years".

Installation:

- Waterproof membrane:

In adhered applications Sarnafil G410-EL is adhered directly to the substrate or a suitable thermal insulation board with Sarnacol 2170, Sarnacol 2172 spray adhesive or Sarnacol 2142s. Laps are then hot air welded to form seams which are stronger than the membrane itself.

Installation is carried out by Sarnafil trained contractors.

- Insulation:

SarnaTherm G can be attached to the substrate (deck or suitable vapour control layer) by mechanically fastening with SBT tubes and SBIW-70x70 pressure plates, or by bonding to the Sarnavap 5000E SA using Sarnacol 2162 cold bonding adhesive or Sika C250 spray applied adhesive.

A vapour control layer will be required when SarnaTherm G is used.

- Vapour control layer:

Sarnavap® 5000E SA is self-adhered to the substrate. Include Sarnafil Primer 600 or Spray Primer 610 to the substrate, and in addition metal deck may need de-greasing using Sarnafil T Prep.
