OptiLineAD PVC Insulation Frame

The OptiFusion MD Triple Gasket Window (76mm, STC 47 / OITC 38 — certified) features a triple central gasket system independently tested to passive house thermal and acoustic standards. The OptiPro MD (82mm) is the highest thermal performer in the Optimedia PVC range — seven-chamber profile, and the most demanding specification in the lineup. Contact Optimedia for certified Uw/U-factor and air-permeability class values.

The OptiFusion MD (76mm, STC 47 / OITC 38) meets passive house thermal thresholds and carries certified US acoustic ratings — making it one of the most complete European PVC specifications for PHIUS-certified projects. The OptiPro MD (82mm) delivers the highest thermal performance in the range. Both are CE-certified under EN 14351-1. Contact Optimedia for complete technical documentation, certified Uw/U-factor values, and test reports.

PVC in white or light-neutral colors performs reliably in most conditions. Dark-colored PVC profiles — anthracite, charcoal, black — absorb solar radiation significantly in Texas, Florida, and Arizona's sustained heat, which can cause irreversible frame deformation. When the frame warps, gaskets stop sealing under compression and the thermal and acoustic performance you purchased is no longer being delivered — and cannot be restored. For dark-color specifications or large-format openings in hot climates, thermally-broken aluminium is the correct engineering choice.

The OptiFusion PVC Triple Gasket Window family is independently certified at STC 47 / OITC 38 — the US-standard values architects and contractors specify directly. Note: acoustic performance is determined primarily by the glass package (laminated glass composition, gap width, gas fill), not the frame material. A quality PVC and a quality thermal-break aluminium window with identical glass engineering deliver similar STC/OITC ratings.

All Optimedia windows are manufactured 100% custom-to-order — no standard sizes are imposed. Production lead time from confirmed order is 3–4 weeks. Every order includes a pre-production technical validation at no additional cost, eliminating specification errors before manufacturing begins. A confirmed order for the US market adds approximately 4-6 weeks for transoceanic logistics, for a total order-to-delivery window of 7-10 weeks. Optimedia products reach the US market exclusively through authorized dealers and distributor partners, ensuring all our customers receive the utmost care and the best possible support from order placement to installation.
