Roof and Wall System.Twin Therm Roof Assembly.Twin Therm is a site assembled built up roof and wall cladding system that has proven itself to offer a consistently reliable building envelope since 1.LDcQpxP' alt='How To Install Roof Cladding Material' title='How To Install Roof Cladding Material' />I am about to construct a three storey building with a basement and I am considering using Solar for the electric energy.Is it possible to install solar panels on.VaproShield designs and manufactures high performance, vapor permeable water resistive barriers WRB and air barrier AB membranes and accessories, creating a total.When installed the system is both non fragile and fully walkable for the duration of its guaranteed life.Twin Therm delivers U values as low as 0.WmK, by increasing the depth of construction without the need for additional components.Air permeability tests on buildings featuring the system have measured as low as 0.Twin Therm comes with a full system guarantee of up to 2.How To Install Roof Cladding Material' title='How To Install Roof Cladding Material' />The entire system and not only its constituent parts, has been independently verified and carries Agrment certification and the Loss Prevention Certification Board LPCB accreditation.No Leaks. The Twin Therm roof system does not allow roof fasteners to penetrate from the outside to the inside of the building, eliminating a major source of leaks.Metal built up roof systems, such as Twin Therm, ensure that any risk from mis drilled or under driven external sheet fasteners do not impact on the weather tightness of the system.If any of the external fasteners were to fail allowing water ingress, water would simply pass through the insulation and onto the liner panel where it would either dissipate or drain out of the cavity into the external gutter.It is common practice to put a flat flashing below the liner panel at the apex and rely on fillers to provide the protection, but at CA Group, whether we are installing a pitched or curved design, we do not believe in compromising the exceptional air and water barrier created by the liner panel.When delivering a pitched roof design, all systems from CA Building Products will utilise a cranked ridge liner panel, installed over the adjacent sheets, to ensure continuity.This common type of cladding consists of a metal liner, a layer of insulation material, a spacer system and an outer metal sheet, as illustrated below.Cladding Coatings are applicators of protective decorative coatings to cladding, roofs, doors windows.Experts in restoration, refurbishment spraying.To deliver the same effect on a curved roof design, the metal and GRP liner panels are taken across the apex.Twin Therm Ridge Detail.Pitched Roof. The main function of profiled roofing and cladding is to create a weather tight envelope, keep the heat in and brace the frame.In order to make a building weathertight, the actual pitch at the end laps must be considered.Since the use of steel profiled sheeting was introduced as a waterproof layer, the industry has limited end laps to a minimum of 4 after deflection.However, in recent years profile manufacturers have developed roof systems which take into account all components used in the tested assembly and, in some cases, it is possible to design a roof with a pitch lower than this recommendation.All roof systems from CA Building Products have been designed and tested to be installed at roof pitches lower than 4.For further information on the design parameters of the systems offered please refer to Technical Information available in the technical section of the website.Curved Roofs. A common misconception about curved roofs is that they cost more than a traditional pitched design.Whilst this may be true of very large radius roofs, where the only option is to use a standing seam or secret fix system complete with barrel vault roof lights, Twin Therm Quantum or Twin Therm Griffon designs are delivered at no extra cost.Most steelwork roofs, even when curved, will use a portal design with faceted rafters, therefore the only cost difference over a standard pitch design is in the extra height required for some of the cleats to achieve the curve this has minimal impact on project cost.The reduction in perimeter detailing through the removal of the ridge components outweighs any additional costs associated with the hoisting and distribution of the longer length sheets.The Twin Therm external and liner profiles have exceptional self curving capabilities with a convex design radius as low as 4.See the Twin Therm Quantum and Twin Therm Griffon sections for more information on enhancements to the Twin Therm design to facilitate lower apex heights.Non Fragility Walkablility.Fully walkable liner.The CA LT 1. 7 1.S 0. 4mm thick steel liner panel is classed as non fragile but it is not walkable.In most applications this is the ideal solution as the thickness provides extreme flexibility to pick up where the secondary steel has settled.This can be enhanced with a CA 3.RL 0. 7 mm thick steel liner panel which is both non fragile and walkable.These two solutions provide superior air permeability results in comparison with the ever increasing thicker sandwich panel options, which due to their rigidity are unable to pick up on the settled steel.The complete system assembly has been extensively tested for non fragility in accordance with ACRM0.Test for Non Fragility of Profiled Sheeted and Large Element Roofing Assemblies Fourth Edition achieving a Class B certification.The relevant Technical Information Paper can be downloaded from the technical section of the website.Health and Safety.Fully walkable systems.With many roofing products and components being well in excess of 2.The Twin Therm system is simple to install, with no heavy individual components, eliminating these risks, both on the ground and at height.All of the roof system assemblies delivered by CA Building Products have been tested for non fragility in accordance with ACRM0.Test for Non Fragility of Profiled Sheeted and Large Element Roofing Assemblies Fourth Edition achieving Class B certification.Today, many Horizontal Life Line HLL system manufacturers and installers are suggesting that their systems are approved or fit for purpose in conjunction with CA Building Products roof cladding systems, this can only be claimed if the systems, in their entirety, have been subject to the relevant tests.For further information refer to ACRCP0.The use of Horizontal Safety Lines in Roofwork.CA Building Products have worked closely with a select few HLL manufacturers to ensure that the safety systems they produce meet the required standards of CA Groups guarantee.Contact CA Group Technical Department for a current up to date list of recommended partners.Thermal Performance.The Matrix Spacer System which is used in all CA Building Products roof and wall cladding systems allows for deeper insulation and flexibility in design, with achievable U values a low as 0.WmK without the need for additional components.All systems available are site assembled and as such allow for specialist components to be added, i.All our systems have been comprehensively tested to prove their structural performance at CERAM.The spacing of the brackets used on the Matrix Spacer System allows the insulation to be installed below the bar without the need for cutting and tucking.U values and system build up information is available from the technical section of the website.Based on current building regulations to meet the minimum backstop U values, the build up depths for the Twin Therm systems areas follows Twin Therm roof CA LT1.S 0. 2. 3WmK 1. Twin Therm roof CA 3.RL 0. 2. 5WmK 1. Twin Therm Wall CA LT1.S 0. 3. 5WmK 1. Good detailing or robust detailing, as it is known, can deliver significant reductions in lost heat and therefore cost.Previous tests have proven that one of the primary causes of heat loss from buildings is due to poor detailing.Poor detailing allows heat to travel from the inside of a building to the outside often via poorly designed flashings, gutters, junctions and interfaces.To put this into context, some details such as drip flashings, which run around the entire perimeter of the building at the base of the walls can, if they are not designed and installed with care, act as huge heat conductors, drawing heat from the warm interior and allowing it to be wasted by passing to the exterior of the building envelope.By insisting on robust detailing the heat sink effect of detailing which allows a direct connection between the inside the warm side and the outside the cold side of a building can be minimised and in some cases, completely eradicated.A thermal performance increase of 7.Attention to detailing like this makes the difference between a good Energy Performance Certificate rating and a poor one.CA Group Technical Department have compiled an extensive library of robust details all of which are offered as standard and delivered at no extra cost, these are available from the technical download section.Material Choices.
