MedO D80 Aggregate Infill

DESCRIPTION
Radmat D80 Infill consists of rock fragments that are used in their natural state, or are used after mechanical processing such as crushing, washing, and sizing. Crushed stone and sand and gravel are the two primary sources of natural aggregate, which are used directly in construction or as a raw material for construction products such as concrete and bituminous road materials.

APPLICATION
Pour into Radmat D80 drainage/retention board. Fill to top and level.

MedO-Wildflower-Plug

MedO Wildflower Plug

DESCRIPTION
Radmat Wildflower Plugs are ready to install plug plants grown in the UK to suit the environment climate.  The range of species provides the opportunity to select plant mixes to achieve a variety of objectives including: extending the flowering season, managing degrees of shade or exposure, orientation and/or indigenous planting requirements.

The range of species provides the opportunity to select plant mixes to achieve a variety of objectives including: extending the flowering season, managing degrees of shade or exposure, orientation and/or indigenous planting requirements.

APPLICATION
Install by hand into a suitably prepared and irrigated Radmat growing medium at the specified rate per m². Insert so root ball is below the finished growing medium surface.  Once installed irrigate for the prescribed period based on season.

FIRE PERFORMANCE
Approved Document B Fire Safety points to the DCLG document Fire Performance of Green Roofs and Walls for best practice guidance in achieving Regulation 7(2) fire compliance with a green roof. DCLG Fire Performance of Green Roofs and Walls states that the compliance requirements for achieving Broof(t4) are a growing medium layer of a minimum 80mm and an organic content of not more than 50% (https://www.gov.uk/government/publications/fire-performance-of-green-roofs-and-walls). In addition, The Green Roof Organisation (GRO) Code of Best Practice, also recommends fire breaks consisting of 50mm deep 20/40mm rounded ballast are used at perimeters and penetrations. Gravel fire/vegetation breaks should be 500mm wide where they abut habitable space but can be reduced to 300mm in some circumstances. Key to ensuring ongoing fire performance of a green roof, and the plant performance, is maintenance as some plants will die back, others will shed leaves naturally during their lifecycle and invasive species will try to take hold. These factors all create additional organic matter that could poses a fire spread risk on the roof therefore unwanted organic matter should be removed as part of the maintenance program.

MedO-Wildflower-Mat-400

MedO Wildflower Mat

DESCRIPTION
Developed through collaboration with the University of Sheffield’s Professor Nigel Dunnett and the Green Roof Centre, Radmat Wildflower Mat is attractive to pollinators and provides a biodiverse, colourful and drought tolerant range of wildflowers, herbs and flowering perennials that will flourish in the conditions created on many types of green roof.

An alternative to SedumPlus it contains a vibrant mixture of wildflowers, herbs and perennials designed to flourish in dry conditions and produce a biodiverse and colourful visual spectacle. The mix contains a range of wildflowers and herbs including Oxeye Daisy, Lady’s Bedstraw, Cat’s Ear, Yellow Chamomile, Wild Marjoram, Thyme and Chives. In addition pink flowering dianthus is included to provide a vivid splash of colour. The result is a vibrant and dynamic display. The flower seeds mix is carefully chosen to produce a wildflower meadow that will flower over a prolonged period, usually from early spring through to autumn, and to create visual interest.

The plants in flower will vary through the flowering season and may vary from year to year as the mixture adapts to the soil type, rainfall and temperature. Wildflowers and other flowering perennials provide a food source for birds and  favourable habitat for butterflies and other insects.

APPLICATION
Unroll over a suitably prepared and irrigated Radmat GM30 Wildflower Substrate installed to a depth of 120mm. Installing a thinner substrate will compromise plant performance and may prevent compliance with the requirements of Building Regulation Approved Document B Fire Safety. Loosely butt sides and ends. Once installed irrigate for the prescribed period based on season.

Esha-Primer

EshaPrimer

DESCRIPTION
EshaPrimer is a quick drying black bitumen priming solution designed to penetrate and seal a variety of porous surfaces including masonry, concrete, cementitious screed/renders, existing bituminous waterproofing and structural steelwork. EshaPrimer creates a base seal and improves the adhesion of bituminous waterproofing solutions.

EshaPrimer is a mixture consisting high quality bitumen’s and hydrocarbon solvents.

APPLICATION
The substrate must be clean and dry, structurally sound and free from laitance, oils, dirt, moss, lichen and loose materials. If applied to an existing roofing membrane the surface must be quite smooth.

Apply by brush or roller ensuring the primer is well applied into the surface. Apply a thin coat and avoid pooling. Allow to dry thoroughly before over coating. Ensure ventilation is sufficient.

EshaPrimer requires between 1 and 4 hours to completely dry. EshaPrimer must be completely dry before applying the bitumen membrane. For additional protection two layers can be used.

Apply as stated only when atmospheric and substrate temperatures are greater than 5 °C. Below this temperature ensure the primer has cured and dried before applying PermaQuik Hot Melt or EshaFlex RBM waterproofing, and if needed heat the surface prior to applying the waterproofing.

MedO Green Roof System

Green Roof System

Radmat-Product-logos-MedO

MedO is a green roof system that utilises established green roofing technologies in a simple and straightforward way. A variety of green roof solutions can be created – from low maintenance sedum matting and wildflower meadows, to landscaped roof gardens with lawns, shrubs and water features.

MedO green roofing systems can transform both new and existing roofs into lush, vibrant, biodiverse environments that protect your roof membrane. The decline of many species of wildflower and insects has accelerated with the decrease of natural habitats – the recent reduction in the bee population is said to be one such casualty. Installing a green roof is an ideal opportunity to create conditions for natural wild flower plants and increase biodiversity, as well as protecting and prolonging the life of your roof membrane. Radmat provide pre-grown sedum matting, wildflower seed mixes and more conventional plug plants varieties.

MedO GS EdgeGuard

DESCRIPTION
MedO GS EdgeGuard provides a fast and simple to install edge restraint system for gravel ballast retention on green roofs. They can also be used to create a hard break between gravel ballast and green roof growing mediums, maintaining gravel fire breaks and helping reduce vegetation transfer into the gravel margin. The slotted vertical face allows for water drainage whilst wide base leg provides restraint without requiring penetration of the waterproofing. Manufactured from aluminium each 2.4m length of MedO GS EdgeGuard is designed so that the folded end of the length can received the ‘tongue’ of another length of MedO GS EdgeGuard, eliminating the need for jointing pieces when used as a complete length. Each length also features a pre-relieved mitre section at the mid length point, enable quick and simple formation of corners and angles without the need for pre-made sections. MedO GS EdgeGuard is supplied self-finished as standard but can be supplied powder coated in any colour, contact Radmat Building Products for lead time. Curved lengths are also available. These require a separate jointing piece for each length

APPLICATION
Loose lay over a suitable Radmat waterproofing membrane, ProTherm inverted roof insulation WFRL or MedO drainage/retention board. Connect each length by slotting the tongue into the folded end of the next piece. Where MedO GS Edge Guard needs to be cut to length ensure the correct end is cut to enable location in to the lengths on either side. Jointing pieces are available should they be required.
