System performance | Warm roof system. |
Preparation | |
Horizontal work | Bauder SA Bonding Primer.Guidance for specification option: Only for concrete decks. Used to seal substrate and improve adhesion. Bauder Activator Primer.Guidance for specification option: A synthetic rubber resin-based material using a non-flammable solvent and propellant system. Bauder Activator-Primer has been specifically developed to provide the necessary preparation of substrates, insulations and underlayers prior to the installation of Self-Adhesive membranes. |
Skirtings and vertical work | Relevant LiquiTOP Primer.Guidance for specification option: Upstands and details to be primed first.
Purpose: Relevant Bauder LiquiTOP Primer substrate primer to seal and prepare dry surfaces of a variety of common substrate material prior to the application of receiving the new Bauder Cold Applied Liquid Waterproofing System to upstands and details only. The following primers must be used as required:
Application: Refer to the current relevant Bauder LiquiTOP Primer product datasheet. Note: For other substrates, consult the Bauder Technical Department for required preparation methods and priming. |
Air and vapour control layer | TEC DBR 06.Guidance for specification option: Suitable substrates: Metal, plywood and oriented strand board (OSB). Not suitable for concrete decks. Self-adhesive elastomeric bitumen air and vapour control layer (AVCL), with an aluminium foil facing for vapour impermeability. The bottom is a peel off release film, covering self-adhesive bitumen. The product is thinner than other Bauder air and vapour control layers and is therefore lightweight. For mechanically fixed insulation only.
KSD FBS.Guidance for specification option: Suitable substrate: Concrete. Robust, self-adhesive elastomeric bitumen air and vapour control layer (AVCL), with a mica finished upper surface to allow easy bonding of insulation using appropriate Bauder Insulation Adhesive. One side lap features an 80 mm wide glass fleece along the underside, and a 100 mm strip of aluminium foil above. The other side lap has a thermofusible film on the top surface. This arrangement ensures that laps are heat sealed using hot air or gas torch as appropriate to extrude a bitumen bead, thus ensuring waterproofing integrity.
Manufacturer guidancePlease consult Bauder for any other deck types not listed and their suitability. |
Insulation | |
Type | PIR FA-TE Flatboard Insulation.Guidance for specification option: Insert required thickness.
BauderPIR FA G16 foil-faced tapered insulation.Guidance for specification option: Insert required thickness.
Manufacturer guidanceU-Values vary depending on thickness and product, consult literature for details. |
Carrier membrane | |
Type | DBR 06 Carrier membrane. |
Liquid-applied waterproofing | |
Type | Bauder LiquiTOP PU, two coats.Guidance for specification option: First/ embedment coat and top coat to be applied with a roller or brush at a minimum rate of 1 L/m². |
Reinforcement | Bauder LiquiTOP Glass Fibre Mat. |
System accessories | Bauder GRP Water Check Trim.Guidance for specification option: GRP roof edge trim for use with Bauder Cold Applied Liquid Waterproofing systems where the system is terminated at perimeter details, such as watercheck kerbs or parapets.
Internal jointing sleeves and 90° pre-formed angles also available. Note: Bauder GRP Water Check Trim to be used on parapets and perimeter kerbs wider than 200 mm – must not be used on its own as a check kerb. Bauder 100/60 GRP Trim Angle.Guidance for specification option: GRP roof edge trim for use with Bauder Cold Applied Liquid Waterproofing systems where the system is terminated at perimeter details, such as drip edges, watercheck kerbs or parapets.
Note: The trim may be used either way round as required.
- The trims must be bedded in Bauder Sealant and mechanically fixed with corrosion resistant flush headed screws. - Fixings centres must be no greater than 300mm with fixings within 50mm of the ends. In high wind risk areas or above 10m high, fixing centres are to be at no more than 150mm. - The new trim must cover any open joint, which may exist between the kerb and the top of the wall by a distance of minimum 20mm. - The reinforced Bauder LiquiTOP System is to be dressed over the trim to its full extent and past the edge of the downward facing edge. Once the system has cured, the excess is to be trimmed off to a neat finish. BauderPVC ABL-R 75, vertical outlets.Guidance for specification option: Flow rate 4.6 L/s (including leaf guard). Suitable for installation into a downpipe size of 75mm.
