Story

Watertight Homes Ltd specialises in the planning, design and installation of all types of structural waterproofing projects. The company holds Triton Approved Contractor status and has a long track record of providing a high quality service to commercial and domestic customers. The company was recently appointed to install primary and secondary waterproofing systems to a new extension built into the hill from an existing school building in Cheshire.

Primary waterproofing protection to all the retaining wall block work was achieved by the installation of Triton’s TWS EX-100 self-adhesive membrane and this was protected by Platon Double Drain and a French drain to the kicker floor. TWS EX-100 is constructed from cross-laminated HDPE sheeting and a bitumen-polymer adhesive compound. The tough, durable membrane is water and vapour resistant and its primary use is for internal and external tanking to prevent the ingress of water and waterborne aggressive salts such as chlorides and sulphates penetrating concrete structures. A unique feature is its selvedge that enables a fast and secure seal on all side edge laps. Before installation of the membrane, TWS-EX Primer was brush applied to the surface to consolidate the substrate and to ensure complete bond development.

Platon Double Drain is a cavity drain membrane designed for external use. It is designed to improve drainage and to protect the underlying waterproofing from backfill damage as its filter fabric layer ensures soil cannot enter the membrane cavities.

A secondary waterproofing layer was achieved by lining the inside face of the retaining wall with Platon P8 – a BBA certified cavity drain membrane manufactured from HDPE. Because of the suspended concrete block and beam floor construction, the P8 was taken down to the foundation without the need for any additional drainage channels. The internal application of Platon P8 membrane enabled a Grade 3 dryness level to be achieved.

Lead flashing work normally requires a specialist roofer and can be hazardous to the installer if strict health and safety procedures aren’t adhered to.The price of lead can also be prohibitive for basic upstand work.

This has prompted introduction of a large number of lead-free flashings, though Klober Wakaflex® stands apart as one of the longest established and highest performing. BBA-certified and with a 20-year guarantee, it is ideal for all roofing types including clay, concrete, slate, metal and polycarbonate. Available in, light grey, anthracite, brown and terracotta (the latter two to special order), it has an aluminium ‘honeycomb‘ mesh embedded into UV-resistant butyl rubber which gives the product similar malleability to lead but with no scrap value. Unlike lead, it can be stretched by up to 50% in length and 15% in width and with no susceptibility to thermal movement it can be laid in long lengths without fixing clips. With no need for forming or other specialist tools Wakaflex provides lasting performance regardless of detailing complexity and can be shaped around deeply profiled tiles or used to seal the top saddle and roof penetrations.

Wakaflex has a high-strength, self-adhesive Butylon® backing which provides immediate weatherproofing and on laps chemically bonds to the facing to provide a virtually unbreakable seal. It is environmentally safe, presents no  contamination problem with water run-off and can therefore  be used with rainwater harvesting systems.No heat, solvents, adhesives or other additional means of fixing are needed and installation can take place in temperatures from minus 40 – 100⁰C, normally without priming.

Story

Architects and consultants can now enjoy a freehand with air curtain design thanks to the Zen from JS Air Curtains. Fascia panels can be custom made in many different materials, screen printed to carry logos or images, and manufactured to incorporate elements such as clocks and LED displays.

Materials designers have specified on custom Zen fascias range from stainless steel, wood, PU leather, high impact polystyrene and PET, each chosen to perfectly match the architecture of the entrance. As the fascias can also be provided with vinyl graphics, fire exit signs and illuminated 3D lettering, the possibilities are limited only by the designer´s imagination.

A “visual installation service”, by JS Air Curtains, allows a designer to preview their creations with a realistic digital mock-up of the air curtain in-situ using an image of the entrance supplied by the client.

The Zen air curtain is supplied as standard with anodized aluminium fascia panels and a galvanised steel central structure finished in black forge; other RAL colours available on request. The unit can be mounted on brackets or drop rods horizontally above doorways up to 4.2m high to seal the entrance with an invisible barrier of air. This helps prevent cold air entering in the winter and cool conditioned air escaping in the summer.

The air curtain is easy to install and available in 0.5m lengths from 1 to 2.5m with the option to join units to cover very wide entrances, making it ideal for use in shops, restaurants, hotels and public buildings.

Heating can be via LPHW, electric or heat pump or alternatively the Zen is available as an air only, non-heated air curtain. Low noise, double-inlet centrifugal fans provide up to 2,700m³/h of airflow per metre of air curtain, with an option for an energy saving EC model. The discharge grille and air intake are in the same plane on the air outlets, so that the air flows through the unit in a straight line, creating a more powerful throw and a tighter seal across an entrance.

The Zen air curtain is supplied, as standard, with a manual controller with five fan speeds with three heater stages on electrically heated models. Seven metres of control cable and an infrared hand-held remote are included. The unit can also be connected to a BMS using protocol Modbus RTU.

A variety of different sensor and switch options can be combined with the Zen’s controllers, including door switches, so the unit only operates when the door is open, time switches, so the units activate during certain hours, and room thermostats, so a constant internal temperature can be maintained.

JS Air Curtains, the UK’s leading air curtain specialist, supply an extensive range of air curtains for all commercial and industrial applications.
