Market knowledge

Construction Foam

If your business operates within the construction industry, you’ll know that foam parts and products are essential for structural integrity, safety, and site efficiency.

The foam materials and products that Polyformes offer are widely used in the construction industry. For example, we supply Evazote closed-cell EVA foam for expansion joints in bridges and stadia, providing a durable water barrier and movement control. We also offer EF400 Ethafoam as a lightweight, impact-resistant alternative to sand under crane spreader plates, alongside LD15 and LD24 Plastazote for conservatory eaves fillers that seal against draughts. For more specialist environments, our LD24 FR and LD45 FR grades are tested to DIN 4102 (B1/B2) for flammability compliance, while our Evazote sheets serve as critical shock-absorbing layers in sports flooring systems designed to BS EN 14904 standards.

We also have extensive experience working with contractors, civil engineers, and building product manufacturers. Our design expertise, deep material knowledge, and in-house conversion equipment allow us to supply the optimal materials, products, or parts for your specific requirements.

Applications

Construction foam uses

The use of foam materials is surprisingly widespread in the construction industry.

While many are more typically used for protective packaging, their unique physical properties – such as moisture resistance, thermal insulation, acoustic dampening, and chemical inertness – make them highly valuable for specific construction applications.

Please note that this list is not exhaustive. If you cannot see your specific application listed, please contact us to see how we can assist.

Material type

Key benefits and properties

Primary construction applications

Plastazote®

Closed-cell, cross-linked polyethylene (PE)

Completely pure and odour-free (nitrogen blown); lightweight; chemically inert; excellent UV and moisture resistance; available in flame-retardant grades.

Expansion joint fillers
Thermal insulation barriers
Waterproof seals and gaskets
Eaves fillers and roofing profiles

ARPLANK

Isotropic expanded polyethylene (EPE) or expanded polypropylene (EPP)

Highly sustainable with high recycled content; 100% recyclable; excellent structural stability; exceptional energy absorption and multi-directional impact resistance.

Structural void fillers
Heavy-duty protective floor coverings during construction
Shock-absorption layers beneath artificial turf or sports flooring

Ethafoam

Closed-cell, non-cross-linked expanded polyethylene (EPE)

High load-bearing capacity; impervious to water, mildew, and rot; outstanding dimensional stability; available in flame-retardant variations.

Impact sound insulation underlays (acoustic flooring)
Concrete curing blankets
Foundation protection boards
Expansion joints in heavy masonry and concrete structures

Evazote

Closed-cell, cross-linked ethylene vinyl acetate (EVA) copolymer

Highly resilient and elastic with a “rubbery” feel; superior resistance to repeated impacts and dynamic loading; excellent chemical and weather resistance.

High-movement expansion joints for bridges and highways
Structural waterproofing membranes
Heavy-duty vibration isolation pads

Microlen

Closed-cell microcellular foam

Exceptionally fine cell structure; superb thermal insulation and acoustic dampening properties; low water vapour permeability.

HVAC duct insulation lining
Acoustic wall and ceiling insulation panels
Under-slab thermal insulation
Piper wrapping and thermal insulation profiles

Stratocell

Laminated closed-cell polyethylene (PE)

Extremely high strength-to-weight ratio; cost-effective; excellent water and moisture resistance; flexible yet structurally stable.

Thermal barrier breaks in metal-framed buildings
Temporary protection boards for glazing and delicate surfaces
Acoustic cavity wall insulation dampeners

Supazote

Ultra-soft, closed-cell, cross-linked polyethylene (PE)

“Super soft” touch and highly flexible; premium comfort and conforming qualities; good sealing capabilities under low compression.

Low-pressure acoustic gap seals
Comfort-backed wall padding and interior trim seals
Highly flexible gap fillers for irregular architectural joints

ZOTEK

High-performance closed-cell fluoropolymer (ZOTEK F) or nylon (ZOTEK N) foams

Extreme high-temperature tolerance; exceptional fire, smoke, and toxicity (FST) ratings; outstanding chemical resistance (especially to hydrocarbons/fuels).

High-temperature pipe and duct insulation
Fire-retardant seals and smoke barriers in commercial high-rises
Chemical-resistant gaskets for industrial facility construction
