Unilin Xtroliner XtroDeck XO/XD Installation Guidelines:

 · Primer should be laid in accordance with the manufacturer’s instructions.

 · The vapour control layer should be fully bonded to the deck and the XtroDeck should be laid into PU adhesive on the vapour control layer in a break bonded pattern.

 · The boards can also be mechanically fixed or adhered with other suitable adhesive approved by the system provider.

 · Fixing heads should be sealed.

 · Laying (Timber Deck) – On plywood decks, XtroDeck should be fully bedded in PU Adhesive over a continuous vapour control layer which has been bonded to the deck.

 · The boards can also be mechanically fixed or adhered with adhesive approved by the system provider.

 · Fixing heads should be sealed.

 · Mechanical Fixing – The specification for fixing Unilin roof boards will vary with the location, roof height/width and topographical data.

 · Architectural specifications should be consulted.

 · Generally with 2400x1200mm boards, a minimum of 6 fixings per board are adequate, located between 50mm and 150mm from all edges, additional fixings may be placed along the centre line.

 · Countersunk washers, 50mm in diameter, should be used with each fixing. However, BS 6399: Part 2 should always be consulted.

 · In two layer systems, all layers should be fixed in accordance with fixing manufacturers instructions.

 · Bitumen Based Built Up Roofing Systems - Technical guidance from the appropriate bitumen waterproofing manufacturer should be sought as to assure proper installation of the bonded built up roofing system.

 · Not suitable for use with a torch on underlays.

 · Fire – Each contract should be assessed for suitability of torch on applications.

 · The suitability of materials, substrates and specifications should be assessed before commencement.

 · Application of the torch on the system should be undertaken only by fully trained personnel with appropriate fire precautions and fire extinguishing equipment available at hand.

 · All timber roof components, and most insulation materials are combustible, and will be vulnerable to a naked flame.

 · These materials may be hidden from view.

 · Due attention should be given and all precautions taken.

 · This is the responsibility of the operatives.

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.


1. Thermal inspection picture in portfolio

It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.

2. Reviews

Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.

3. Compare prices

Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 

4. Word of Mouth

The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.


Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
