Carmika Air Vent - Ventilated Spacer System

Smart Ventilated Spacer System for Metal Roofs and Wall Insulation.

Carmika Air Vent, under the Carmika brand by Shish SmartBuild, is a ventilated spacer strip designed to improve the thermal performance of insulated metal roofing and wall systems -- particularly for PEB structures, industrial sheds, and agricultural sheds.

In conventional installation, insulation sheets are laid directly under metal roof sheets, causing direct heat conduction from the metal surface into the insulation, reducing its efficiency.

Carmika Air Vent solves this problem by:

  • Creating a 1-inch air gap between insulation and metal sheet.
  • Allowing hot air to rise and escape naturally upward.
  • Allowing cool air to enter from bottom openings.
  • Enhancing thermal barrier performance of insulation.

Result:

  • Lower internal temperatures.
  • Improved energy savings.
  • Longer lifespan for insulation systems.

At Shish SmartBuild, we design smarter roofing systems that breathe, ventilate, and insulate better.

Key Features and Custom Options

Creates Ventilated Air Gap

Maintains 1-inch separation between insulation and outer metal sheet for better performance.

Improves Insulation Efficiency

Prevents direct heat conduction into insulation materials.

Promotes Passive Air Circulation

Hot air rises upward naturally; fresh cool air enters from lower sides.

Durable Polyolefin Hollow Core

Lightweight, rigid, UV-resistant, moisture-resistant, and impact-resistant.

Simple Installation

Fastened easily over insulation before roof sheeting is installed.

Flexible Usage

Can be used independently or combined with Carmika Ridge Vent for full passive ventilation.

Maintenance-Free

No moving parts; once installed, provides lifetime passive performance.

Self-tapping screws

Foil tape (optional)

Installation Instructions:

1. After Laying Insulation Sheet

  • Lay insulation sheets over purlins.

2. Fix Carmika Strip Vent

  • Place Strip Vents over insulation aligned horizontally or vertically.
  • Maintain approx. 1 to 1.5 feet spacing between strips.
  • Fix using self-tapping screws directly into purlins.

3. Install Metal Roofing Sheets

  • Fix outer metal sheets directly over the strips.
  • Ensure tight fit and correct alignment of metal sheets.

4. Installation Tips

  • Avoid crushing Strip Vent while fastening.
  • Maintain consistent spacing across the roof.
  • For best results, use with Carmika Ridge Vent for full bottom-to-top ventilation.
