CA Building Products Twin-Therm® is a site assembled roof and wall cladding system that provides a Non-Fragile assembly, guaranteed U-values complying with current and proposed Building Regulations and up to a 40 year full system guarantee.
The system offers developers, specifiers and architects a cost effective reliable cladding solution, while allowing the building designer the freedom to choose from a number of trapezoidal, arc and sinusoidal wall profiles, ensuring Twin-Therm® caters for every architectural need.
The system’s design and installation method allows for the insulation to be installed continuously, prior to fixing of the spacer system, minimising thermal bridging. The Therma-bar is then installed on top of the insulation eliminating the need to cut and tuck. The sealed liner panel acts as the vapour control layer, so there is no need to install a separate vapour control layer or breather membrane unless a Class 5 humidity construction is required.
The system can be specified and supplied in conjunction with our ‘sequential sheeting’ packing system, which provides the liner panels and external profiled sheets packed in the order in which they will be installed onto the roof, reducing build times considerably.
All materials within the Twin-Therm® system are fully recyclable to enable low ‘cradle to cradle’ carbon footprint, with a net commercial benefit on scrap values at end of life. The Therma-quilt non-combustible insulation is supplied with zero Global Warming Potential and zero Ozone Depletion Potential. The system has a minimal environmental impact of material delivery; this is due to its flexibility which enables it to cover a high service area when being transported to site.
The Twin-Therm® system is now available with the Corus Confidex Sustain® Guarantee, ensuring all of the unavoidable carbon emissions created throughout the entire life of the Twin-Therm® cladding system, cradle to cradle, is offset by investing in environmental projects worldwide.
The Twin-Therm® system is supported by a comprehensive training regime from CA Building Products Technical Department, offering in-house training, onsite inductions and detailed design for installers.
The system is available in Corus Colorcoat HPS200® Ultra and Prisma®.
Twin-Therm® Guarantees
Unlike most suppliers of twin skin cladding, CA offer full system guarantees for up to 40 years. The Complete Assurance guarantees cover the manufacture and design of the whole system including all components within the system, supplied by CA, such as, screws, sealants, insulation, spacers, etc. There are three Twin-Therm® guarantees available from CA Building Products.
Twin-Therm® 40
Twin-Therm® 40 consists of the normal Twin-Therm® 25 build up; however the external sealants are of a higher grade, which contribute towards the 40 year system life. The only other variations are the internal and external rooflights which are of a different composition and thickness. This is a more expensive rooflight assembly than the Twin-Therm® 25 year option. This delivery complements the Corus Confidex® Guarantee 40 year system and maintenance free coating introduced in 2008 and allows the client/specifier to have comfort that the entire roof or wall is covered for up to 40 years depending upon colour and building location.
Twin-Therm® 25
Twin-Therm® 25 roof and wall cladding system comprises a standard construction in terms of durability and Non-Fragility for a 25 year period, including stainless steel fasteners and incorporating standard rooflights. This system has been widely adopted throughout the specification market for many years culminating in almost 1,000,000m² being installed year on year. This delivery is offered alongside the Corus Confidex® Guarantee for Colorcoat HPS200® Ultra and Colorcoat Prisma®.
Twin-Therm® 12
When 25 year guarantees are not required, we offer the Twin-Therm® roof and wall cladding system with a 12 year Complete Assurance guarantee. It is effectively the same as is offered with Twin-Therm® 25, but with carbon steel fasteners in place of stainless steel (with exception to rooflights). Again, the Corus Confidex® Guarantee for Colorcoat HPS200® Ultra and Colorcoat Prisma® still applies.
