Airtight protection for west coast of Scotland self-build

The threefold combination of the Wraptite®, Wraptherm® and Reflectatherm® airtightness and vapour barrier systems from A. Proctor Group has been chosen to provide enhanced thermal performance and protection for a sea-facing SIPS construction self- build property on the west coast of Scotland.

The self-build project managed by Phil and Lynn Dickinson is designed by architects Allan Corfield Architects, and is located in Craobh Haven, a unique location that combines the beauty of an Atlantic Rainforest with stunning sea views. Craobh Haven is a small purpose-built village and sailing port on the west coast of Argyll and Bute, Scotland.The main contractor for the project is Rochead Irvine Construction.

The key requirements for the project included a Fabric First design, SIPS construction, and breathability, plus protection from the Argyll coast exposed site. In addition, the client design sought to achieve excellent insulation values, and highly efficient thermal airtight performance.

Wraptite is installed as an external air barrier and alternative to a traditional standard breather membrane. Wraptite is the only self-adhering vapour-permeable air barrier certified by the BBA and combines the essential properties of vapour permeability and airtightness in one self-adhering membrane.The self-adhered nature of Wraptite and its high level of water resistance and simplified detailing made it an ideal choice.

The self-adhering nature of the Wraptite allows a simple and fast installation process. It also has excellent weather protection and water-tightness properties.The membrane can be installed directly to walls and openings with speed and efficiency, enabling internal fit-out to begin more rapidly than in traditional forms of construction.

Alongside the Wraptite membrane, the thermal and airtightness performance of Wraptherm is included in the build. Wraptherm is a high-performance membrane composite that is self-adhesive and consists of a 10mm Spacetherm aerogel insulation blanket bonded to the face of Wraptite.

The final part of the airtightness and vapour barrier system is provided by Reflectatherm Plus, a reflective, high-resistance vapour barrier for internal walls, ceilings and floors that will significantly reduce the risks of condensation by providing the highest levels of moisture resistance.

Reflectatherm Plus is an industry-leading reflective vapour barrier.

It combines the highest thermal performance in its class with a high vapour resistance to prevent interstitial condensation and is suitable for use in walls, ceilings, and floors on the warm side of the insulation.

The clients were supported throughout the project by the A. Proctor Group Technical team. Expert advice is available at all stages of the building process, from design work to on-site support.
