Construction Foam by Oodles of Noodles

Construction Foam shelf at the Oodles of Noodles lido

This lane is trade stock, the working cousin of the pool noodles next door. Backer rod goes into a joint before the sealant so the bead bonds to two sides instead of three, which is what stops it tearing when the joint moves.

Sizes here cover 1/4 inch to 4 inch rod, soft and standard types, in short packs and in rope coils up to 4000 ft. Pipe covers from the Foam King line slip over 1/2 inch and 3/4 inch copper, and roll bar padding is sold pre-slit and fire retardant.

Rule of thumb: pick a rod about 25 per cent wider than the gap, roll it in with a blunt tool so the skin stays whole, then tool the sealant over the top.

Construction Foam in use

Before you order

Closed-cell rod will not soak up water, which is why it suits outdoor joints. Open-cell soft type compresses further and suits irregular cracks — check the listing for which type you are ordering.

Rope coils are sold by length, not by weight, so a 4000 ft reel of 1/4 inch rod and a 600 ft reel of 1 inch rod cost about the same. Work out the run first, then the diameter.

Trade stock, same material

Backer rod, foam rope and pipe covers are close relatives of the Oodles of Noodles pool noodles on the other shelves — the same premium closed-cell foam tube, extruded to a trade diameter. The quality questions are identical: even cells, an intact skin and a rod that measures what the label says.

Sizes run from a 1/4 inch standard rod up to 4 inch, with white and grey the usual colours and coils reaching 4000 ft.

Check before you order

Check the joint width in inch, then pick a rod about a quarter wider so it compresses and stays put. Measure the whole run before you choose a diameter — ordering twice costs more in freight than the approx. value of the foam.

Fast jobs fail at the rod more often than at the sealant, which is why a favorite trick on site is to roll a test length into a spare inch of joint first. The experience is quick and the saving is incredible compared with cutting out a torn bead next spring. A long coil of Oodles of Noodles rod is the cheapest foam in the range by the foot, which is why it turns up in workshop crafts as often as in expansion joints.

Questions about construction foam

What size backer rod do I need?

Roughly 25 per cent wider than the gap, so it compresses into place and stays. A 1/2 inch joint takes 5/8 inch rod.

Soft type or standard?

Soft type squashes further and suits irregular cracks. Standard closed-cell rod is firmer and sheds water, which suits outdoor expansion joints.

Does the rod go in before the sealant?

Yes. It sets the depth of the bead and stops the sealant bonding to the back of the joint, which is what lets the joint move without tearing.
