Fibreglass insulation | Advantages - Choose type and ...

Fibreglass insulation (glass wool)

Fibreglass insulation is one of the most frequently used insulation materials in the house. It is made of recycled glass fragments and pure sand. It is available in the shape of blankets or sheets. Thanks to the soft structure of glass fibre insulation, irregularities can easily be removed.

Contact us to discuss your requirements of formaldehyde-free glass wool. Our experienced sales team can help you identify the options that best suit your needs.

 

Applications

Glass wool is especially used as an indoor thermal and acoustic insulation material. They are most commonly applied underneath pitched roofs, wooden floors or on internal walls. Glass wool primarily appears inside the house as it quickly loses its insulation value when it comes into contact with damp.

Advantages and disadvantages of glass wool

Disadvantages of fibreglass insulation

When processing and installing fibreglass insulation, mineral fibres are released. These may cause irritation and inflammations of the eyes, skin and airways. It is therefore advisable to wear a mask, dust goggles and gloves.

 

Advantages

  • Easy to install, even for do-it-yourselfers
  • Fireproof material
  • Perfectly suited to seal uneven surfaces, thanks to its compressibility
  • Quite cheap insulation
  • Recyclable insulation that is recovered from residues

 

Choose the right material for every job

Fibreglass insulation is available in different variations, shapes and thicknesses. Always check which type you need in order to avoid unnecessary costs and bad insulation values. Below, you can find an overview of the different options:

 

Available thicknesses of fibreglass insulation

The thickness of glass wool insulation has a big impact on the acoustic and thermal insulation value. Thicknesses of fibreglass insulation start from 60mm and increase by 20 mm (80, 120, 140, 160, 180,&#;). A minimal thickness of 160mm is recommended in order to insulate a pitched roof. To make sure there are no seams, you may as well work with two alternating layers.

Available finishes and shapes of fibreglass wool

Glass wool is available in the shape of supple sheets, blankets or in bulk. Sometimes, a finish layer is already provided on the outside. This can make it easier to work (in the case of paper) or it can either be used as a vapour barrier (in the case of aluminium). One can use the overlapping finish to seal seams or to staple it onto wooden constructions.

 

 

Install glass wool insulation &#; always provide a vapour barrier!

To prevent the fibreglass insulation from absorbing damp from the rooms, you must always provide a vapour barrier on the inside of every room. Use, for example, insulation blankets with an aluminium coating and seal the seams with matching tape.

Glass wool is an insulation material made from glass fibers and arranged into a wool-like texture using a binder. The process traps many small pockets of air within the glass and these small air pockets result in high thermal insulation properties. Glass wool is produced in rolls or slabs with different thermal and mechanical properties. The mineral raw material melts at about to °C. An aqueous binder is sprayed onto the fibers during the spinning process. The fibers cool quickly and harden like glass. For more&#;
