Main purpose

Passivhaus certified internal airtight, vapour barrier (vapour impermeable) racking board for timber frame walls and ceilings.

Use it on

Timber studs and rafters on the interior side of timber frame walls, stud partitions and roofs.

Overview

SuperPan VapourStop is a structural high-density chipboard with an airtight vapour control coating applied to both sides. It has achieved a Class A Passivhaus component certification. It is intended for internal use and is specially designed to be more airtight and resistant to water vapour compared to conventional plywood or OSB3. It also provides the superior bending strength and racking strength compared OSB3 with much high level of stability in humid conditions.

Where to use it

SuperPan VapourStop can be fixed to the internal side of timber frame walls, stud partitions and rafters.

What it does

The board provides extremely high levels of airtightness and is vapour impermeable, acting as an effective vapour barrier. It is moisture resistant and frequently used in Passivhaus or any low energy project, as a superior alternative to conventional OSB3. 

The special film applied on both sides of the board act as effective airtightness and vapour control layer. 

How it works

The board has a transparent airtight vapour control coating on both sides. This makes the product fully airtight over its entire surface turning it into a much more reliable airtight and vapour control layer, compared to conventional OSB3. The board must be airtight sealed to adjacent boards, ceilings and floors with suitable airtightness tapes and seals such as Pro Clima Tescon Vana.

Why we love it

SuperPan VapourStop is sourced from sustainably managed forests with full EPD certification. It provides Passive House levels of airtightness and controls moisture vapour while maintaining the breathability of a building especially when used in conjunction with diffusion open/breathable materials outside such as Gutex woodfibre or Elka Strong Board. It is easy to install, fix screws through and saw.

Its unique make up, composing of a high performance P5 chipboard sandwiched between 2 layers of high density woodfibre also offer unique structural and practical benefits including high strength, stability and less swelling, with less breakout when cutting. The board guarantees continuous vapour control over the whole surface of the board thanks to the integrated air and vapour barrier film which is pre-applied on both sides of the boards.

Installation Guide

How to Install

An expansion gap of at least 3mm is required between each board. For large walls 5-12m wide, the expansion gap in corners should be calculated as 2mm per linear metre of wall. For walls that are longer than 12m wide, the corner expansion gap should be calculated as 3mm per linear metre of wall.

SuperPan VapourStop does not have an inner or outer face so it can be installed facing in either direction.  

Screws, nails or staples should be used for installation. The screws or nails should be galvanised, stainless steel or have similar durable properties. Nails should have a minimum diameter of 2.8mm and a minimum length of 50mm. Nails or fixings around the edge of the board should be applied every 150mm (or closer) and the nails on intermediate studs (in the middle of the board) can be up to 300mm apart. Nails, screws or staples should be fixed at least 8mm away from the edges of the board.

SuperPan VapourStop can be used on studs that are at least 38mm wide and no more than 610mm apart. After the boards have been installed, all joints between boards, adjacent walls and ceilings should be taped using Pro Clima's Tescon Vana, Tescon No.1 or Uni Tape, for the best results.

Hints and Tips

SuperPan VapourStop should be stored flat and installed in dry conditions.
