The 25mm Unilin Thin-R FR/BGM Flat Roof Insulation Board is faced with a polypropylene fleece finished bitumen glass-fibre working surface and a mineral glass facing to the underside.
FR/BGM boards are suitable for use with most bitumen based, partially bonded waterproofing systems typically including a BS EN 13707: 2013 (Flexible sheets for waterproofing).
Reinforced bitumen sheets for roof waterproofing type 3G perforated base layer or proprietary system.
Unilin Thin-R FR/BGM (Fleece side upper most) may also be fully bonded.
During the construction process, the construction should be protected from rain penetration during breaks in the process.
With fully bonded applications additional care is required to ensure that the construction remains free from moisture.
Failure to protect will result in blistering of the waterproof layer.
Unilin FR/BGM can be used as a cheaper alternative to Celotex, EcoTherm, Recticel and Kingspan TR24 Therma Roof insulation boards.

Unilin FR/BGM Roof Design (Roofing Systems Installation):
· FR/BGM is suitable for use with most bitumen based, partially bonded waterproofing systems typically including a BS 747 type 3G perforated base layer or proprietary system.
· FR/BGM, (Fleece side upper most) may also be fully bonded.
· Guidance in regard to moisture and condensation should be in accordance with BS 8217.
· During the construction process, the construction should be protected from rain penetration during breaks in the process.
· With fully bonded applications additional care is required to ensure that the construction remains free from moisture.
· Failure to protect will result in blistering of the waterproof layer.
· The fall on a flat roof should be designed to ensure that rainfall does not pond.
· The boards are suitable for use on roof decks that are subject to limited maintenance foot traffic.
· Walkways should be provided on roofs requiring regular pedestrian access.
· When the roof is complete, protective boarding should be laid if additional site work is to be carried out.
· Built up roofing systems should be finished with a suitable reflective layer such as chippings.
· The fire rating, when tested to EN 13501-5 and BS 476 Part 3 ‘External Fire Exposure Roof Test’, will be dependent upon the waterproofing system specified.
· Decks should be primed before the application of the hot bitumen used to bond the vapour control layer.
· Reference should be made to BS 8217 when applying the vapour control layer.
· Carry the VCL past the insulation and seal with the parapet wall.
· On metal decks, Unilin FR/BGM should be laid break bonded into hot bitumen (max temperature 240°C) mopped or poured over the vapour control layer.
· The boards can also be mechanically fixed or the mineral coated glass fibre facer (MG) can be adhered with other suitable adhesive.
· Fixing heads should be sealed with bitumen.
· Laying (Concrete Deck) Ensure concrete decks are laid to provide correct falls to outlets and are clean, dry, without projections.
· Primer should be laid in accordance with the manufacturer’s instructions.
· The vapour control layer should be fully bonded to the deck and the Unilin FR/BGM should be laid into hot bitumen on the vapour control layer in a break bonded pattern.
· The boards can also be mechanically fixed or the mineral coated glass fibre facer (MG) can be adhered with other suitable adhesive.
· Fixing heads should be sealed with bitumen.
· Laying (Timber Deck) On plywood decks, Unilin FR/BGM should be fully bedded in hot bitumen over a continuous vapour control layer which has been nailed or bonded to the deck.
· The boards can also be mechanically fixed or the mineral coated glass fibre facer (MG) can be adhered with other suitable adhesive.
· Fixing heads should be sealed with bitumen.
· 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 1200mm x 600mm boards, a minimum of 4 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 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.
· 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.

INSTALLERS
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.
4 TIPS FOR CHOOSING THE BEST INSULATION INSTALLER
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.
