60mm FR/ALU Unilin Thin-R is a gas-tight aluminium foil faced PIR rigid foam flat roof insulation board used for mechanically fixed single ply waterproofing roofing systems.

Flat Roof Board FR/ALU is used as a thermal insulation and to create or improve falls on limited access concrete, timber or metal flat roof decks, in new and existing buildings.

Unilin FR/ALU Insulation Board is designed for use in conjunction with a vapour control layer and a single-ply mechanically fixed roof waterproofing membrane.

FR/ALU flat roof boards should be laid over the vapour control layer in a break bonded pattern.

Unilin Thin-R flat roof insulation boards should be secured by approved mechanical fixings.

The requirement for a separate vapour control layer should be assessed in accordance with BS 6229.

Typically, a 1000 gauge polythene should be used with all joints lapped and sealed.

Any fixings that penetrate it must be of the self sealing type that fuse to the vapour control layer during application.

Flat Roof FR/ALU foil faced insulation boards are suitable for use on roof decks that are subject to maintenance traffic.

The completed roof should not be used for storage of heavy materials or an air conditioning plant.

Unilin Thin-R FR/ALU Flat Roof Board Installation Guide:

 · The water vapour control layer should be laid with 150mm laps, which are turned up at any vertical upstand.

 · When the insulation boards have been positioned, the laps are turned over and sealed prior to the roof finish being completed.

 · The Flat Roof ALU foil faced boards should be laid over the vapour control layer in a break bonded pattern.

 · The long edges of the boards should be laid at right angles to the corrugations and all board joints must be fully supported by the deck.

 · The boards are generally secured by approved mechanical fixings.

 · The Flat Roof ALU boards are laid over the vapour control layer in a break bonded pattern and secured with approved mechanical fixings, or secured under a ballasted system.

 · Care should be taken to ensure that the concrete deck is graded to the correct falls, dry, clean and free from any projections or gaps.

 · The specification for fixing Unilin roof boards will vary with the location, roof height, area and topographical data.

 · Architectural specification should be consulted.

 · Generally, with 2400mm x 1200mm boards, a minimum of 6 fixings are adequate, located between 50mm and 150mm from all edges, additional fixings may be placed along the centre line.

 · Additional fixings around roof perimeter may be required.

 · 11 fixings per 2400mm x 1200mm sheet is recommended.

 · Counter sunk washers, 50mm in diameter, should be used with each fixing.

 · However, BS 6399 Part 2 or BS EN 1991-1.4: 2005 + A1: 2010 (National Annex to Eurocode 1.Actions on structures. General Actions. Wind Actions) should always be consulted.

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.
