Eight different materials are commonly used in the insulation of commercial and industrial buildings: Calcium silicate, mineral fibre, cellular glass, expanded silica, elastomeric foam, foamed plastic, refractory fibre, and insulating cement. These materials all have different mechanical and chemical properties for insulation, and come in the form of rigid boards, blocks, pre-formed shapes, flexible sheets, flexible blankets, cements, and foams for application.

Insulation systems are intended to facilitate temperature control, conserving energy by reducing heat loss or gain, increasing operating efficiency of HVAC systems, and reducing emissions of pollutants to the atmosphere. However, one important factor is often overlooked in building insulation – the accessories, leading to reduced efficiency.

Accessories important to effective insulationWhen insulation accessories are not given much attention, the dependability and performance of the entire insulation system could be at risk, according to Rubber World Industries. This is why many insulation contractors and suppliers, especially in HVAC systems, take the “total system” approach to include all accessories necessary.

Accessories play different roles in ensuring insulation is optimal. One of the most critical is securing primary insulation and jacketing. Most insulation is not a structural material, so it needs to be supported, secured, fastened, or bonded in place. The most common accessories used for this purpose are studs and pins, staples, rivets, screws, clips, straps, tapes, and adhesives.

Another critical role of insulation accessories is in the reinforcing of cements and mastics. This is to provide mechanical strength, which accessories like fibre fabrics, expanded metal lath, metal meshes, and wire netting offer.

Insulation accessories are also useful for flashing and stiffening. Flashing directs the flow of liquids away from the insulation, which can be constructed out of metal, plastic, or mastic. Stiffening is applied on high temperature surfaces before heavy density insulation is installed, providing added strength. Metal lath and wire netting can be used for stiffening.

Other insulation accessories include sealers, caulking, and tapes to seal vapour and weather-barrier jackets, joints, as well as protrusions, designed to have a range of temperature and vapour permeability properties. Accessories like slip joints, bedding compounds, and flexible sealers serve as compensation for expansion or contraction in primary insulation.
