Cladding Solutions

Hal Mann Vella is a ‘dream come true’ for any designer, as HMV has the ability to work natural marbles and granites
or agglomerated marbles and then manufacture terrazzo tiles, pre-cast terrazzo elements or reconstituted stone
flooring and accessories to match or blend with the natural stones or to a designer’s palette.
Whether you are working on a granite-clad office tower, a marble hotel lobby, or a simple vanity, table or kitchen
top, Hal Mann Vella has the materials and expertise to put things together on schedule and within specified budgets.
HMV holds a sizable stock of over 60 colours and types of natural marbles and granite.

RAINSCREEN CLADDING SYSTEM

The essentials of a Rainscreen system are to allow the ingress of air at the base of the system and the egress of air at the top of the system. This ventilated cavity allows any water which penetrates the panel joints to be partly removed by the ‘stack effect’ and partly removed by running down the rear face of the panels and out of the base.

ADVANTAGES

Installation is simple – allowing external cladding and internal works to proceed speedily, early and consecutively
Problems of deterioration are halted with minimal additional load being applied to the existing structure
Aesthetic colour, flexibility and shape of external facade may be dramatically altered
Energy saving – lower running costs due to greatly improved thermal insulation
Easily removed panels for monitoring of structure
Reduction of the risk of condensation due tothe elimination of cold bridges

APPLICATIONS

Wall cladding and facade finishes
Fascias and soffits
Column covers
Balcony and canopy cladding
Stairways and lifts
Roof edgings and parapet wall copings

PRINCIPLES

A Rainscreen system consists of an outer panel, a ventilated cavity and an inner leaf
In driving rain conditions moisture forms a membrane across the baffled vertical and horizontal joints
The majority of water is deflected off the outside face – any penetrating water is disposed of through drainage
Rainscreen systems differ from wall sealed construction as the beneficial effects to air movement are utilised
A Rainscreen system is pressure equalised – the joints are open or lightly baffled, allowing pressure equalisation in driving rain conditions to be instantaneous. Pressure inside the cavity is equal to pressure. outside

FACADE ENGINEERING

As part of a comprehensive technical support service, Hal Mann Vella can provide assistance for the safe and
optimised setting out of the grid system through the preparation of ‘project specific’ static calculations. These
calculations determine the engineering requirements of the façade, through the most practical and economical use
of the system components.
On most projects appearance, suitability, availability and cost are likely to be the determining factors. Ideally the stone or
Engineered materials selected will be the most appropriate for the application, readily available, produced to the required
tolerances and within budget. In all instances detailed research should be underken to establish the technical
competency of the stone at an early stage.

RAINSCREEN CLADDING

Rainscreen cladding is generally defined as panels that are individually supported and restrained allowing construction to
take place with open joints. Differential movement is accommodated in each joint, which negates the need for larger
compression and expansion joints. Open jointed systems provide a ventilated cavity and require waterproof rainscreen
insulation systems. Ventilated cavities assist in achieving the demands of the new European energy saving requirements.

NATURAL STONE TESTING

To meet the latest requirements and to confirm the stones suitability for use in a specific application, tests should be
undertaken in accordance with the appropriate standards as set out in BS EN 1469.

MATERIALS

GRANITE

An igneous rock formed from volcanic magma, producing the hardest and most durable of all natural stones, making it suitable for all Construction, landscaping And interior applications. Massive worldwide availability of literally hundreds of different Granites gives Designers the confidence to specify the product of their choice with guaranteed delivery.
Finishes: polished, honed, flamed, brushed / antique.

Applications: cladding, masonry, flooring, paving, worksurfaces.

MARBLE

A hard crystalline metamorphic rock composed primarily of calcite which has been used as a building and flooring material for centuries. The recognisable and characteristic veining in marbles are due to various mineral deposits like clay, sand and iron oxide which were originally present in the sedimentary Limestone.

Finishes: polished, honed

Applications: cladding, flooring, bathrooms and vanity tops.

TERRACOTTA/CERAMICS

Through the years, terracotta and ceramics have been used successfully as a building material. Contemporary architecture and manufacturing techniques have produced a vast new selection of products for cladding purposes.

Finishes: smooth, glazed and sand blasted
Applications: cladding, sunscreens and acoustic panels

TERRAZZO

Engendered terrazzo cladding panels specially developed to meet the performance requirements of the ventilated facade cladding. Panels with maximum format of 120cm x 120cm.

Finishes: polished, brushed, homed, ribbed and 3D surface.

Applications: cladding & paving.

HARDSTONE

A sedimentary rock composed of calcium carbonate which has formed on the sea bed millions of years ago from the remains of seashells and marine organisms.
