An effective combination of three active ingredients, together with our proven immersion-treatment method, helps ensure strong protection on every exterior wood surface of our window and patio doors.

11. What are the Key differences between EnduraGuard and JELD-WEN’s AuraLast?
Treatment Method: Pella uses an immersion process; JELD-WEN uses a pressure-treat process
Moulding and Tenoning: Pella moulds and tenons parts before they are immersed; JELD-WEN moulds and tenons after parts are treated, which could result in weaker protection on cut surfaces.
Active Fungicides: Pella has three active fungicides for a broader base of protection against stain and decay caused by mold and mildew; JELD-WEN uses one active ingredient which is known to have gaps in protection, specifically against stain fungi.
Woods Treated: EnduraGuard is used on all wood types sold by Pella; AuraLast is only used on pine, an immersion process is used on their other wood types.
