FR vs FR-LSH vs Finolex Ultra: Which House Wire Should You Choose?

Finolex house wires come in a few grades, and the names can be confusing. Here's what FR, FR-LSH and Finolex Ultra actually mean — and where each one fits in a home.

FR — Flame Retardant

The standard, most widely used house wire. FR insulation resists catching fire and slows flame spread. It's a solid, value-for-money choice for general home wiring.

FR-LSH — Flame Retardant Low Smoke & Halogen

Everything FR does, plus it releases less smoke and fewer toxic halogen gases if exposed to fire. In a house fire, smoke and gas are often more dangerous than flames — so FR-LSH (Finolex's Flamegard range) is a smart upgrade for bedrooms, children's rooms, and enclosed or poorly-ventilated areas.

Finolex Ultra — E-Beam, Low Smoke Zero Halogen

Finolex's premium wire, using electron-beam (E-Beam) irradiated insulation for superior heat resistance and the lowest smoke and halogen emission. It's the safest choice for premium homes and anyone who wants maximum fire safety.

Which should you choose?

• Budget-conscious, general wiring → Finolex FR.
• Better fire safety for living spaces → Finolex FR-LSH.
• Premium home, maximum safety → Finolex Ultra.
