2 Pro Steps for Insulating Your Gas Lines


– Step 1: Insulate the gas line thermally

– Step 2: Insulate the gas line system (pipes) acoustically

Insulating your gas lines (pipes) has a double advantage: limiting heat loss and noise in your pipes. We distinguish between:

– The thermal insulation of a pipe consists in wrapping the pipe in an insulating sleeve.

– The sound insulation of your pipes consists, for example, in changing the fixing collars for anti-vibration foam collars.

1. Insulate the pipe thermally

Gas Lines

Insulating your gas lines can significantly impact your energy costs, especially if they run through unheated areas such as the cellar, garage or attic. It avoids heat loss and, in extreme cases, freezing of pipes.

To insulate your pipes thermally:

– Measure the length of your pipes and cut the insulation sleeves to the desired size using a cutter.

– Put them in place:

◦ either by clipping them around the pipe;

◦ or by rolling them up if they are pre-slit.

– For pre-slit sleeves:

◦ Close the edges of the sleeve with suitable glue for better efficiency and a good hold.

◦ If you need to make sleeve connections, use the glue to make pooled connections to avoid thermal bridges.

Tip: also, wrap the clamps with the sleeves.

For elbows

– In the case of polyethylene sleeves:

◦ Make a bevelled cover with a cutter, and secure the fitting with tape.

– In the case of rubber sleeves: their flexibility allows without cutting to pass the corners.

For T-fittings

– Make a V-shaped opening in one of the sleeves with a cutter, and a point in the other, so that the interlocking is maximum.

– Then, tape the two elements together.

For delicate areas (faucet or floor penetrations…)

When the installation of a sleeve is delicate, or even impossible, use a heat tape, thinner and more flexible:

– Wrap the heat tape around the pipe.

– Tape it with adhesive tape.

2. Soundproofing the pipe

Gas Lines

Soundproofing the pipework can help to combat certain pipe noises, depending on the nature of the pipe.

Reduce the water pressure

Reduce the water pressure of the circuit (it may be too high); you will reduce the noise pollution caused by your pipes.

Unless you know where and how to change it, call a professional.

Change the clamps

Change your clamps to foam-filled clamps that are specifically designed to be anti-vibration.

Removal is simple:

– Use a screwdriver to unscrew it.

– Then, place the new clamp in place of the old one and screw it on.

Note: you can also insert small rubber pieces between the existing collars and the pipe; this rubber will absorb the vibrations.

Fill in the ducts

If your pipe is inside a duct, fill it with mineral wool.

Bleed your radiators

A lack of bleeding can also cause noise in the pipes. Remember to bleed your circuit at the beginning of winter!
