Correctly installed insulation or composite panel insulated sheets will help to reduce heat gain in the summer and retain heat in the winter months, which will in turn reduce the running costs of the building. Having the correct insulation at the right thickness is crucial to obtaining the desired level of insulation or U-value.
Trisomet Composite Panel Insulated Sheet
Trisomet insulated composite panel sheeting is the most efficient way to create an energy efficient, low carbon roof. It is manufactured to stringent quality standards compiling with the requirements of ISO 9001, insurance industry standard of ‘Factory Mutual’ fire regulations and ‘Loss Prevention Council Board Certification’ of insulation performance. The finished product is also subjected to performance testing in accordance with the European Quality Standard BS EN 14509.
Trisomet composite panel insulated sheeting is supplied in 40, 60, 80, 100 and 120mm core thickness (depending on what level of insulation or ‘U’ value you want to achieve). This is made up of a rigid PIR urethane insulation core sandwiched between a 32/1000 box profile top sheet and a metal white liner sheet on the reverse. This gives 1 metre width cover when lapped and can be made up to 10 metre lengths (longer by arrangement, depending on transportation). The sandwich construction of this sheet gives it added strength, making it the strongest sheet we supply requiring less purlin supports, it can be used on roofs with a minimum pitch of 4º and is suitable for both roof and wall cladding. It is fixed through the lower part of the profile to the purling using longer self drilling TEK screws to suit the core thickness of the sheet.
Alternatively, cheaper methods of creating an insulated roof can be achieved by either laying rigid insulation board above the roof purlins, then laying sheeting on the insulation and using extra long TEK screws to fix through both sheet and insulation into purlins, or insert rigid or quilted insulation between purlins after a single skin roof has been laid. This method will require cutting the insulation to fit between purlins and will require board under the purlins to give a finished appearance and hold the insulation in place.
