AlphaGuard PUMA Warm Roof System (25 Year Warranty)

Guidance for specification option:

AlphaGuard PUMA systems possess a variety of independently assessed accreditations for performance such as British Board of Agrément, European Technical Assessment and a Broof(t4) fire rating under BS EN 13501-5:2016 fire classification of construction products and building elements.

AlphaGuard PUMA systems comply with the performance guidelines set out in relevant UK Building Regulations, BS 6229:2018 Flat roofs with continuously supported flexible waterproof coverings, and LRWA codes of practice.

AlphaGuard PUMA membranes also offer exceptional elongation and crack bridging properties that ensure long term durability.

TremStik spray-on primer.

Guidance for specification option:

A solvent based synthetic rubber primer specially developed for the effective adhesion of self-adhesive or torch applied membranes to compatible substrates.

Once spray applied with the specific applicator gun, TremStik Spray-on Primer should be touch dry within 2—3 minutes achieving a coverage rate of approximately 12 m²/L dependent on substrate porosity. Spray applied application should be undertaken 10—20 cm away from the designated substrate and with a single pass ensuring an even spread of product. Please refer to the Tremco technical data sheet for further details.

As horizontal work.

TremVap.

Guidance for specification option:

Bituminous self-adhesive air and vapour control layer (AVCL) / carrier membrane that is reinforced with composite aluminium foil and glass fibre mat. TremVap has an extremely high vapour resistance and can provide an effective barrier against warm moisture laden air rising through the system.

The upper foil facing is polyester coated and provides an ideal substrate for TremStik polyurethane adhesives when adhering TremTherm insulation boards.

Membrane laps should be minimum 80 mm with overlaps facing down the roof slope to avoid negative laps. Rolls should be laid out perpendicular to the specified falls on the roof."

TremStik PU adhesive.

Guidance for specification option:

Insulation boards should be laid out in break bond pattern, fully supported, and with all edges closely butted together to ensure thermally continuity. When laid on metal decks with partial support, the long edges of the boards should be laid perpendicular to the crowns of the metal deck with all board joints fully supported.

Insulation boards are typically adhered using TremStik PU adhesive but in certain circumstances the boards can be mechanically secured with appropriate fasteners and pressure plates. Mechanical fixing patterns are subject to project specific wind uplift calculations.

TremVap.

Guidance for specification option:

Bituminous self-adhesive air and vapour control layer (AVCL)/ carrier membrane that is reinforced with composite aluminium foil and glass fibre mat. TremVap will provide an ideal base layer to carry and retain the specified liquid system.

Membrane laps should be minimum 80 mm. Rolls should be laid out perpendicular to the specified falls on the roof. TremVap should be dressed 50 mm above the line of the thermal insulation or to the height of any vertical thermal breaks.

Self-adhesive.

Guidance for specification option:

TremVap is applied to TremTherm insulation by means of the self-adhesive backing. The insulation surface must be suitably primed with TremStik Spray-on Primer prior to application.

AlphaGuard PUMA WP.

Guidance for specification option:

A highly elastic, fully reinforced, polyurethane modified, methyl methacrylate liquid applied membrane that cures in minutes with an advanced catalyst activation. AlphaGuard PUMA WP has exceptional elongation and crack bridging properties offering a robust waterproofing layer that can easily cope with normal levels of structural or thermal movement.

AlphaGuard PUMA WP is hand-applied in two separate coats with AlphaGuard PUMA 165g Reinforcement Fabric installed between each coat. Each coat should be applied at a rate 1.4kg/m² achieving a final waterproofing layer of 2.8 kg/m² (minimum 2 mm dry film thickness). Catalyst mixing is typically 2% by weight (20°C or below) but can be adjusted for lower ambient temperatures.

AlphaGuard PUMA 165 g reinforcement fabric.

Guidance for specification option:

A strong, stitch bonded, polyester reinforcing fabric that provides enhanced strength to liquid applied membrane systems.

AlphaGuard PUMA 165g Reinforcement Fabric is applied between separate coats of AlphaGuard PUMA membrane. AlphaGuard PUMA 165g Reinforcement Fabric should be carefully embedded into the base coat, lapped by minimum of 50 mm, and laid flat without creases, air pockets or prominent fibres.

AlphaGuard PUMA coloured top coat.

Guidance for specification option:

A polyurethane modified methyl methacrylate liquid coating that cures in minutes with an advanced catalyst activation. AlphaGuard PUMA Coloured Top Coat will provides a durable and long lasting finish.

AlphaGuard PUMA Coloured Top Coat is hand-applied with an application rate of 0.3-0.5 kg/m² in a single coat. Catalyst mixing is typically 2% by weight (20°C or below) but can be adjusted for lower ambient temperatures.
