Render

There has been a notable increase to the diversity of render systems and facade finishes over recent years. These changes have responded to the increase in demand for more durable products that have the versatility to be applied to a host of different substrates and thereby improve the environmental standing of any building. At the same time, the advances in design and technology now provide architects and designers with an array of options to realise the most diverse of creative aspirations.

“We excel at applying modern materials that have the qualities to meet even surpass the demands of today’s building requirements.”

Render Systems

Whilst HR Plastering have the capacity to work with all types of conventional renders we excel at applying modern materials that have the qualities to meet even surpass the demands of todays building requirements. We use Sto products who offer three key types, Acrylic resin render, Silicone resin render and Lotus-Effect render. Each one provides the technical characteristics that far exceeds conventional renders such as Lime, cement and silicate; these are all breathable but fail in terms of cracking and weather resistance.

• Acrylic resin renders

  Acrylic resin renders are highly elastic making them resistant to cracking. They have the best adhesion co-efficient and are easy to apply and texture. Acrylic renders offer the widest choice of colour and the best colour stability.

• Silicone resin renders

  Silicone resin renders combine the benefits of mineral binders with synthetic binder types. They have excellent water repellency, vapour permeability and good dirt resistance, but a limited colour choice.

• Lotus-Effect render

  An innovation unique to Sto. StoLotusan is the only render on the market with the patented Lotus-Effect. It demonstrates unbeatable water and dirt repellence, and provides the best natural protection against algae growth.

Sto-Brick Slips

Sto-Brick Slips are manufactured from synthetic render, providing the same durable weatherproof properties as Stolit, but with a simulated brick appearance. Compatible with all Sto facade systems, you can match the design of nearby buildings without compromising on external wall insulation. Sto-Brick Slips are available in six standard brick colours, or can be custom-made in any colour or size as required.

Rainscreen Cladding

A ventilated rainscreen cladding system with a seamless render finish - and no limit on the lightness value. The StoVentec R system is fixed to the exterior wall with an adjustable aluminium sub-construction. This creates a cavity between the facade and the render carrier board which is part-filled with mineral fibre insulation for effective external wall insulation. The system protects the wall, keeping it dry while also allowing it to breathe. And because the cavity is ventilated, there is no limit to the lightness value of the render finish. Even the darkest colour values can be used.

Colours

Colour can transform a building and Sto offer 800. However as well as the aesthetic considerations there are practical implications to be conscious of. There are only a few pigments that keep their colour under the influence of sunlight long term. Sto renders feature a number of binders (acrylic, silicate and silicone resin). These binders each have different pigment carrying capacities and need to be cross referenced if a specific colour is required. Finally, in practice it is not advisable to have a dark intense colour render with an external wall insulation system. The walls will heat up too much through thermal gain.

Textures

From natural stone appearance to ultra-fine grain the choice of textures are vast. We have the skill to apply heavy textures, good for very even surfaces to the less forgiving finer textures, that without skill and care are susceptible to imperfections such as, bumps, depressions and trowel marks.
