70-90mm TR/MG Unilin Thin-R Tapered Roof is a rigid foam PIR insulation board with mineral coated glass facers used below single ply waterproofing systems and partially bonded built-up felt roofing systems.

Unilin TR/MG tapered roof insulation boards are embedded in a layer of bitumen on a 3G type felt to BS EN 13707: 2013 (Reinforced bitumen sheets for roof waterproofing that has been adhered to the deck).

TR/MG board is a practical solution to water ponding with insulation and drainage in a single system or mechanically fixed roof membrane systems and most partially bonded built-up felt systems.

Unilin TR/MG, a rigid thermoset PIR mineral-coated glass-fibre faced board used as a thermal insulation and to create or improve falls on limited access concrete, timber or metal decks.

These tapered roof insulation 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 or adhered using other suitable adhesive.

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

Tapered Roof TR/MG is suitable for use on roof decks that are subject to maintenance traffic.

Unilin TR/MG Tapered Flat Roof Board Installation Guide:

 · Decks should be dry and clean of debris with tapered components laid to achieve the designed falls.

 · The boards can be secured using approved mechanical fixings and washers, with boards laid with a break bonded pattern or can be adhered using other suitable adhesive.

 · Joints should be closely butted.

 · The tapered boards should be laid over the vapour control layer in a break bonded pattern.

 · The boards are generally secured by approved mechanical fixings.

 · The waterproofing is also mechanically fixed in accordance with the specific manufacturer’s instructions.

 · Laying (Concrete Deck) - Decks should be dry and clean of debris.

 · The boards can be secured using approved mechanical fixings and washers, with boards laid with a break-bonded pattern.

 · Joints should be closely butted.

 · Alternatively the boards can be adhered to the decking with approved adhesive systems.

 · Partially bonded built–up felt waterproofing should be laid, where in accordance with BS 8217 (Reinforced bitumen membranes for roofing code of practice).

 · Fully Adhered Systems - The boards are suitable for use with most fully adhered single-ply waterproofing membranes.

 · Board joints and abutments should be taped subject to the approved adhesive system being used.

 · A fleece backed membrane might be required with the system being used, check with the system manufacturer.

 · 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 TR/MG tapered boards should be waterproofed as soon as possible after fixing.

 · Fixings - Depending on the fixings specification chosen, quantity and pattern of fixings will vary with the location, roof height/width and topographical data.

 · Architectural specifications should be consulted.

 · Generally with 1200mm x 1200mm boards, a minimum of 4 fixings per board are adequate, located between 50mm and 150mm from all edges.

 · If more than one layer of insulation is being used, the flat board packers should be mechanically fixed with a minimum of one fixing before fixing profiled boards.

 · Additional fixings around the roof perimeter of the roof may be required.

 · 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.

 · It is recommended to seek advice from the fixing manufacturer for specific guidance.

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