Polynor Premium Mega Pro 70 expanding foam with gun, 12 pcs.

Polynor Premium Mega Pro 70 - high-yield expanding foam

A set of twelve cans of one-component PUR polyurethane foam together with an application gun, intended for installing windows and doors and for sealing gaps and joints. Each 850 ml can yields up to 70 liters of foam, which allows efficient work on larger construction projects.

Use

The foam bonds materials such as concrete, wood, PVC or aluminum, and works both for installing window and door joinery and for filling voids and gaps in walls. The formula can be used over a wide temperature range from -10°C to +35°C, which makes it an all-season product.

Technical properties

The uniform foam structure prevents splattering during continuous application, and the absence of secondary expansion eliminates the risk of deforming the installed elements. Low thermal conductivity (lambda 0.034 W/m*K) provides good thermal and acoustic insulation for many years of use.
