50-70mm Unilin TR/BGM Torch-on Tapered Insulation, a rigid foam polyisocyanurate board with a mineral-coated glass fibre facing on one side and a composite bitumen/glassfibre facing on the other.
Unilin TR/BGM boards are not reversible, they are suitable for use below most bitumen based partially bonded built up roofing systems and partially bonded torched-on systems.
The TR/BGM boards are suitable for use with most bitumen based waterproofing systems including those using a BS EN 13707: 2013 type 3G perforated base layer.
The roof should be laid in accordance with BS 8217 (Reinforced bitumen membranes for roofing. Code of practice).
During the construction process, the construction should be protected from rain penetration during breaks in the process.
The fall on a flat roof should be designed to ensure that rainfall does not pond.
These boards provide a practical solution to water ponding with insulation and drainage in a single system.
Built up roofing systems should be finished with a suitable reflective layer such as chippings.

Unilin TR/BGM Installation Guidelines:
· Roof Loading - These 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 sitework is to be carried out.
· Roof Finish - Built up roofing systems should be finished with a suitable reflective layer such as chippings.
· Advice should be sought from system manufacturers.
· Fire Performance - 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.
· Vapour Control Layer - Decks should be primed before the application of the hot bitumen used to bond the vapour control layer.
· Reference should be made to BS8217 when applying the vapour control layer.
· Carry the VCL past the insulation and seal with the parapet wall.
· Laying (Metal Deck) - On metal decks, Unilin TR/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 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 TR/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 (Plywood Deck) - On plywood decks, Unilin TR/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 glassfibre facer (MG) can be adhered with other suitable adhesive.
· Fixing heads should be sealed with bitumen.
· Daily Working Practice - The facing of these boards should not be considered as temporary waterproofing, when work is interrupted or at the end of each day, a night joint must be made to prevent water penetration.
· Unilin tapered boards should be waterproofed as soon as possible after fixing.
· Fixing - The specification for fixing of Unilin roof boards will vary with the location, roof height/width and topographical data, architectural specification should be consulted.
· Generally with 1200mm x 1200mm boards, a minimum of 4 fixings per board, located between 50mm and 150mm from all edges, additional fixings may be placed along the centre line.
· Countersunk washers, 5mm 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 the contained instructions.
· It is recommended to seek advice from the fixing manufacturer for specific guidance.
· 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 roof system.
· Fire - Each project 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 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 insulations materials are combustible, and will be vulnerable to 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.

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.
