About Duct Insulator Spacers

Duct Spacers shall be made from ABS Acrylonitrile Butadiene Styrene (ABS). (1.04 specific gravity

has been chosen by TECAFINE for the manufacture of all interlocking module spacers

because of its flexibility, strength, and resiliency.

(A) Under compressive stress

(B) The spacer modules can be freely handled on the job site without breakage.

Since many utilities install underground systems year-round, and most large projects carry through more than one year, it is important to use a formulaon of ABS for spacers that will not be adversely by the extremes of summer or winter temperares. Finally, Rib wall construction makes it possible to design a spacer which will hold safely the vertical

loads normally encountered when men work atop large duct banks.

Spacers shall consist of interlocking modules. The interlocking modules shall include an

internal vertical channel on both side edges of the spacers. When the duct bank is

assembled.

Engineered for Lasting HVAC Performance

Our Duct Insulator Spacers offer robust support for insulation in ducting systems, thanks to their durable HDPE construction and certified ASTM D1248 material grade. They are rated to carry up to 120 kg and endure demanding thermal ranges from -20C to +80C, making them suitable for various climates and environments.

Seamless Installation and Environmental Compliance

These spacers are manually placed using a simple push-fit connection, requiring no special tools or adhesives. They are fully RoHS compliant and 100% recyclable, reflecting a strong commitment to environmental responsibility and operational safety in every installation.

FAQ's of Duct Insulator Spacers:

Q: How are Duct Insulator Spacers installed in duct support systems?

A: Duct Insulator Spacers are installed manually using a straightforward push-fit method. No special tools or adhesives are needed; simply align and securely place the spacer between the duct and the support structure for quick and effective installation.

Q: What benefits do these insulator spacers provide for HVAC ducting applications?

A: These spacers improve thermal insulation by maintaining a consistent gap between duct and insulation material, prevent thermal bridging, and provide structural stability with their 120 kg load-bearing capacity. Their HDPE construction ensures excellent UV, chemical, and corrosion resistance, promoting durable HVAC system performance.

Q: When should I consider choosing fire retardant versions of these spacers?

A: Fire retardant variants are recommended when installing ducts in areas with higher safety requirements or where additional fire protection is mandated by local building codes or project specifications.

Q: Where can these spacers be used, and what insulation materials are they compatible with?

A: The spacers are suitable for use in HVAC ducting systems up to 100 mm diameter and are compatible with both foam and glasswool insulation, making them versatile for commercial, industrial, and residential installations.

Q: What is the process for maintaining or replacing these spacers?

A: No maintenance is required due to their robust material and resistant properties. In the rare case of replacement, the manual push-fit design allows for simple removal and substitution without disrupting the ducting system.

Q: How does the environmental compliance of these spacers benefit my project?

A: Being RoHS compliant and fully recyclable, the spacers contribute to greener building practices and facilitate easier certification for environmentally conscious construction standards.
