Foil Faced Ductwrap & Netting
Services shall be insulated with Paroc IceRock / Paroc Hvac flexible mineral fibre wrap, foil faced, joints sealed with self adhesive aluminium foil tape, secured with 50mm mesh galvanised wire netting.
components:
Wire Netting
Chicken wire is
manufactured of thin, flexible galvanized steel wire, or stainless steel with hexagonal gaps.
Self-Adhesive Aluminium Foil Tape
Bostik T74 High Tack Foil Tape has been developed to deliver instant adhesion, mouldability, durability and reliability even when applying at temperatures as low as -5°C.
Designed for use in the heating, ventilation and air conditioning sector, it is ideal for lap sealing foil faced insulation materials, both rigid and flexible.
It is manufactured to the highest specifications and is coated with a high tack pressure sensitive acrylic adhesive, which is protected by a removable release paper.
PAROC Hvac Ductwrap
PAROC Hvac Mat AluCoat is a non-combustible stone wool mat. It is used for thermal and condensation insulation of circular and rectangular ventilation ducts. It has a reinforced aluminium facing.
Icerock Ductwrap
Icerock Ductwrap is a light density stonewool mat covered with a reinforced Aluminium foil on one side.
recommended insulation thickness in mm (particular project specifications may differ):
Chilled and dual-purpose ducts
BS5422:2009 (table 14) - Control Heat Transfer
Whilst it is impossible to account for all scenarios, the following act as general guides:
50mm thick
These thicknesses may not satisfy all criteria and design requirements.
Warm air ducts
BS5422:2009 (table 13) - Control Heat Loss
Whilst it is impossible to account for all scenarios, the following act as general guides:
Within Building 40mm thick, Plant rooms & external locations 50mm thick
These thicknesses may not satisfy all criteria and design requirements.
Chilled air in ambient conditions
BS5422:2009 (table 12) - Condensation Control
Whilst it is impossible to account for all scenarios, the following act as general guides:
Within Building 40mm thick, Plant rooms & external locations 50mm thick
(min air inside duct 15 degC)
These thicknesses may not satisfy all criteria and design requirements.
