AlphaGuard BIO Warm Roof System (20 Year Warranty)

Guidance for specification option:

AlphaGuard BIO 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 BIO 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 BIO membranes offer exceptional low odour application with an enhanced environmental profile.

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 dependant on substrate porosity. Spray applied application should be undertaken 10-20 cm away from the designated substate 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 BIO.

Guidance for specification option:

A fully reinforced, two-component, polyurethane liquid applied membrane with catalyst technology. AlphaGuard BIO has exceptional low odour properties and provides a robust waterproofing layer that can easily cope with normal levels of structural or thermal movement.

AlphaGuard BIO Basecoat is hand-applied in two separate coats with AlphaGuard 225g Reinforcement installed between each coat. AlphaGuard BIO Basecoat should be applied at a rate 0.8 kg/m² achieving a final coverage of 1.6 kg/m². To complete the membrane system, AlphaGuard BIO Top Coat is hand-applied in a single coat at 0.8 kg/m².

AlphaGuard 225g Reinforcement.

Guidance for specification option:

A strong, chopped strand matting, glass fibre reinforcement that provides enhanced strength to liquid applied membrane systems.

AlphaGuard 225g Reinforcement is applied between separate coats of AlphaGuard BIO Basecoat. AlphaGuard 225g Reinforcement should be carefully embedded into the base coat, lapped by minimum of 50 mm, and laid flat without creases, air pockets or prominent fibres.

TremDome.

Guidance for specification option:

A traditional domed style rooflight that includes a thermally broken insulated kerb with excellent natural light transmittance properties. TremDome rooflights come with a variety of ventilation accessories and can be operated manually or electronically. Design is subject to survey or client requirements.

TremDrain.

Guidance for specification option:

Gravity drainage outlets that have an integral membrane flange for sealing flat roof membranes. TremDrain outlets are manufactured from aluminium, are suitable for all roof types and offer excellent flow rate. Type, size, and design is subject to survey or client requirements.

TremClip.

Guidance for specification option:

Lightning protection systems are frequently installed to buildings to avoid damaging and costly lightning strikes. TremClip has a threaded securement base that includes a separate retaining clip to secure lightning conductor tape at predefined centres across the roof.

TremFlash.

Guidance for specification option:

A1 non-combustible secondary cover flashing manufactured from soft and workable zinc alloy. Primarily used as lead substitute in flat roof details such as wall chases or abutment flashing.

TremTrim.

Guidance for specification option:

TremTrim is a prefabricated GRP edge trim that is specifically designed for multiple flat roof waterproofing types. Compatible with various Tremco reinforced bitumen membrane and liquid applied membrane systems, TremTrim provides an effective termination of the specified waterproofing systems at the perimeter edge.

Ilbruck SP510.

Guidance for specification option:

General purpose low modulus sealant that is silicone free and cures to form a tack free surface. TremSeal mastic can be used to enhance the waterproofing integrity of a wide variety of detailing situations.
