Common Questions About NT

What is Twinsulator?

Twinsulator is NT's thermally broken aluminum system. A thermal barrier separates the interior and exterior aluminum to reduce heat transfer while keeping a slim profile.

When should I choose Twinsulator?

Twinsulator is a good match when you want aluminum aesthetics, slim frames, and modern thermal performance. Contemporary homes and larger window openings are often a great fit.

Is Twinsulator comparable to vinyl for efficiency?

Twinsulator is dramatically better than older aluminum systems and is designed to meet modern efficiency requirements. Premium vinyl can still be slightly more efficient, but Twinsulator closes most of the gap.

What finishes are available?

Aluminum systems can support a wide range of durable powder coat finishes. If you want darker exterior colors, aluminum often handles it better than vinyl.

Do you install NT vinyl?

Yes, when it matches the project goals. We will compare the vinyl options available and recommend what fits the style, performance needs, and layout.
