Fire protection for an exterior environment

A good fire protection must work in all environments, especially exteriors where the stress is greatest. The challenge with exterior fire protection is that the fire class must be maintained over time, and not affect the visuals. Therefore, at NTL, we always recommend topcoating to achieve local requirements for long-term durability.

Maintenance schedules

Fire impregnation provides fire protection with deep penetration through the wood. This means topcoat maintenance schedules are provided to maintain fire protection over time, giving you peace of mind as a retailer.

Minimal visual impact on wood

We use a transparent liquid with minimal impact on the original appearance of the wood.

Fire protection in an interior environment

The increasing trend of visible wood used in interior environments places higher demands on fire protection. To avoid covering wood with, for example, gypsum boards, fire impregnation can be a great alternative. Unlike exterior protection, however, the interior environment places high demands on smoke development and its toxicity levels (VOC).

Interior wooden panel, fireproof


Fire impregnation that achieves B-s1, d0 enables visible wood for interior use without any covering materials like gypsum boards.

Environmentally friendly

Our product enables re-use and recycling of timber products after achieved life span and has low emission values (TVOC)


In contrast to a surface fire treatment, fire impregnation enables sawing, cutting and wear & tear of the wood without affecting the fire protection.

Painting or laquer after fire impregnation

A valid fire classification must also include the painted or laquered surface layer. Therefore, fire tests of the final product, including treatment, are always required.

Fire classification with color and laquer

Thanks to fire tests performed on painted, fire-impregnated wood, we have fire classifications for painting or laquering with most paint manufacturers.

Painted durability

Since the combination of the fire protected wood and paint is classified, the fire class will be maintained over time by just following the maintenance scheme for the paint.

Easy to paint

Our fire impregnation allows for painting afterwards. This is due to the natural surface of the wood not changing.

The fire test SP Fire 105 ensures that BBR:s requirements for facades on buildings over two floors are followed. It's a construction-specific fire test, which means it's not black or white.

It's always up to each and every fire consultant if the documentation for SP Fire 105 is applicable for the specific project.

Yes, we offer CE-certified painting via our industrial painting partners.

Fire impregnation creates increased flexibility because the fire protection penetrates straight through the wood. This creates the opportunity to cut and saw the wood after impregnation and maintain the fire class, something that is not possible with surface treatments.
