VIP+ Datasheet

VIP+ consists of micro-pourous fumed silica material (silicon carbide, hydrophilic silica, and polyester fibres), contained within a vacuum sealed envelope (multi-layer aluminium foil wrapper), manufactured in accordance with prEN 17140.

These panels are specially designed to be utilized where space is a premium as the vacuum properties offer a very low thermal conductance which means a much thinner insulation can be used in comparison with other conventional insulation products.

Supply & Installation

VIP+ can be successfully installed in floor, wall and roof applications.

Sizes / Thicknesses Available

Board sizes range up to 900 x600 and are available in the following thicknesses: 25mm, 30mm, 40mm, 50mm.

Thermal Performance

The product has an aged thermal conductivity of 0.007 W/mK

Fire Performance

For further details on a full system performance please contact your waterproofing system supplier / membrane manufacturer. The performance to DD CEN/TS 1187: 2012 will be reliant on the full system tested. In isolation the product is classified as European Classification F in accordance with BS EN 13501-1

Restrictions:

The metallized, multilayer plastic film of the VIP+ must not be damaged by drilling, cutting, milling, nailing, otherwise the internal pressure of the panel will rise, and the special properties of the panel will be lost.

Additional Infomation

Xtratherm FR/BGM is 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. Advice should be sought from system manufacturer.

The fire rating when tested to EN 13501-5 and BS 476 Part 3 ‘External Fire Exposure Roof Test’ will be dependent upon waterproofing system specified.

Xtratherm FR/BGM is suitable for use with most bitumen based, partially bonded water proofing systems typically including a BS 747 type 3G perforated base layer or proprietary system.

Xtratherm 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 (Reinforced bitumen membranes for roofing.

* 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.

Decks should be primed before the application of the hot bitumen used to bond the vapour control layer. Reference should be made to BS 8217:1994 when applying the vapour control layer. Carry the VCL past the insulation and seal with the parapet wall.

On metal decks, Xtratherm FR/BGM should be laid break bonded into hot bitumen (max temperature 240°C) mopped or poured over the vapour control layer. The board can also be mechanically fixed or adhered with other suitable adhesive. Ensure all edges of the boards are supported.

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 Xtratherm 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 adhered with other suitable adhesive.

On plywood decks, Xtratherm 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 adhered with other suitable adhesive. Fixing heads should be sealed with bitumen.

The specification for fixing Xtratherm roof boards will vary with the location, roof height/width and topographical data. Architectural specification 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. Counter sunk washers, 50mm in diameter should be used with each fixing. However, BS 6399: Part 2 should always be consulted. In two layer systems, all layers should be fixed in accordance with fixing manufacturers instructions.

Technical guidance from the appropriate bitumen waterproofing manufacturer should be sought as to assure proper installation of the bonded built up roofing system.

Each contract 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 insulation materials are combustible, and will be vulnerable to a 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.
