Product Installation - Kingspan TR24

Falls

The fall on a flat roof, constructed using Kingspan Thermaroof® TR24, is normally provided by the supporting structure being directed towards the rainwater outlets. The fall should be smooth and steep enough to prevent the formation of rainwater pools. In order to ensure adequate drainage, BS 6229: 2003 (Flat roofs with continuously supported coverings. Code of practice) recommends uniform gradients of not less than 1 in 80. However, because of building settlement, it is advisable to design in even greater falls. These can be provided by a Kingspan Thermataper® tapered roofing system).

Tapered Roofing

Kingspan Thermaroof® TR24 is also available in a tapered version, Kingspan Thermataper® TT44, comprising a high performance rigid thermoset insulation core, manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP), faced on the underside with a mineralised glass tissue autohesively bonded to the insulation core during manufacture.

The top surface is finished with a bitumen coated glass tissue finished with a thermofusible polypropylene fleece. Kingspan Thermataper® TT44 comes with a supporting design service. This ensures that the most cost−effective solution for a roof is identified and that the end result is a tapered system design which meets a roof's rainwater run−off and insulation requirements. Further details of Kingspan Thermataper® TT44 are available from the Kingspan Insulation Tapered Roofing Department (see rear cover), which should be consulted as early as possible in the process of designing a roof.

Roof Waterproofing

Kingspan Thermaroof® TR24 is designed for use in conjunction with most partially bonded torch applied multi-layer bituminous waterproofing. When applying waterproofing, torch with minimum heat at all times. Torch the roll of waterproofing felt using flame/edge guards at all times. Do not directly apply the torch to the insulation facing. The waterproofing membrane should be installed in accordance with the membrane manufacturer’s instruction. For further advice please contact the Kingspan Insulation Technical Service Department

Water Vapour Control

Kingspan Thermaroof® TR24 should be installed over a separate vapour control layer, in new build roofs, unless it is being used in conjunction with a sealed metal deck. Regardless of the deck type it is recommended that a condensation risk analysis is carried out for every project. For refurbishment projects, involving the addition of insulation to existing insulated flat roofs, or roofs constructed of insulated steel faced composite panels, it is imperative that a U–value calculation and condensation risk analysis is carried out for every project, in order to ensure that the correct thickness of insulation is installed to achieve the required thermal performance, whilst avoiding interstitial condensation.

Installing over Metal Decks

Metal decks should be clean, dry, without large projections, steps or gaps, and should be graded to allow correct falls to all rainwater outlets.
If the metal deck is not sealed, and the insulation boards are to be bonded down, in order to ensure an adequate bond between the metal deck and the vapour control layer, the metal deck should be suitably primed, in accordance with the primer manufacturer’s instructions, prior to the application of the hot bitumen, or suitable alternative proprietary adhesive system, used to bond the vapour control layer to the deck.
If the metal deck is not sealed, and the insulation boards are to be mechanically fixed, the vapour control layer should be loose–laid.
Where one run of the specified vapour control layer laps another, there should be minimum 150 mm side and end overlaps, which should be adequately sealed.
Turn up the vapour control layer at the edge of the roof to a height appropriate to the specified waterproofing membrane.
Boards of Kingspan Thermaroof® TR24 should be secured to the deck using mechanical fixings e.g. telescopic tube fasteners (see ‘Mechanical Fixings’).
Alternatively, the insulation boards should be bonded down by laying into hot bitumen (max. temperature 240°C) mopped or poured over the vapour control layer / sealed metal deck, or with the use of a suitable alternative proprietary adhesive system.
Insulation boards should always be laid break–bonded, either with their long edges at right angles to the trough openings, or diagonally across the corrugation line, and with joints lightly butted. There should be no gaps at abutments.
A 25mm upstand should be used around the perimeter of the roof on theinternal façade of parapets.
A minimum distance of 300 mm should be maintained between the top of the insulation upstand and the bottom of the horizontal roof insulation.
The waterproofing membrane is installed in accordance with the membrane manufacturer’s instructions, over the whole insulated area including any insulation upstands, as soon as possible after laying the insulation boards.

Installing over Concrete Decks

Concrete decks should be clean, dry, without large projections, steps or gaps, and should be graded to allow correct falls to all rainwater outlets.
If the insulation boards are to be bonded down, in order to ensure an adequate bond between the vapour control layer and the concrete deck, the concrete or screeded surface should be suitably primed, in accordance with the primer manufacturer’s instructions, prior to the application of the hot bitumen, or suitable alternative proprietary adhesive system, used to bond the vapour control layer to the deck. ● If the insulation boards are to be mechanically fixed, the vapour control layer should be loose–laid. ● Where one run of the specified vapour control layer laps another, there should be minimum 150 mm side and end overlaps, which should be adequately sealed. ● Turn up the vapour control layer at the edge of the roof to a height appropriate to the specified waterproofing membrane ● Boards of Kingspan Thermaroof® TR24 should be bonded down by laying into hot bitumen (max. temperature 240°C) mopped or poured over the vapour control layer, or with the use of a suitable alternative proprietary adhesive system. ● Alternatively, the insulation boards should be secured to the deck using mechanical fixings e.g. telescopic tube fasteners (see ‘Mechanical Fixings’). ● Insulation boards should always be laid break–bonded, either with their long edges at right angles to the edge of, or diagonally across the roof, and with joints lightly butted. There should be no gaps at abutments. ● Roof–light or ventilator kerbs etc. should always be insulated with the same thickness of Kingspan Thermaroof® TR24 a the general roof area
A 25mm upstand should be used around the perimeter of the roof on theinternal façade of parapets.
● A minimum distance of 300 mm should be maintained between the top of the insulation upstand and the bottom of the horizontal roof insulation. ● The waterproofing membrane is installed in accordance with the membrane manufacturer’s instructions, over the whole insulated area including any insulation upstands, as soon as possible after laying the insulation boards.

Installing over Existing Flat Roofs

● The existing waterproofing membrane surface should be clean, dry, without large projections, steps or gaps, and should be graded to allow correct falls to all rainwater outlets. ● Where the existing waterproofing membrane is not fit for purpose as a vapour control layer, and the new insulation boards are to be bonded down, a separate vapour control layer should be bonded to it with hot bitumen, or suitable alternative proprietary adhesive system. If the insulation boards are to be mechanically fixed, the vapour control layer should be loose–laid. ● Where one run of the specified vapour control layer laps another, there should be minimum 150 mm side and end overlaps, which should be adequately sealed. ● Turn up the vapour control layer at the edge of the roof to a height appropriate to the specified new waterproofing membrane. ● Alternatively, the insulation boards should be secured to the deck using mechanical fixings e.g. telescopic tube fasteners (see ‘Mechanical Fixings’). ● Insulation boards should always be laid break–bonded, either with their long edges at right angles to the edge of, or diagonally across the roof, and with joints lightly butted.
