Why TOTAL70
5-chamber baseline, 6-chamber Edge upgrade
TOTAL70 ships with 5 thermal chambers as standard — already two more than most budget UK uPVC systems. Where extra performance is wanted at the seal (north-facing elevations, exposed sites, Future Homes Standard-aware refurb), TOTAL70 Edge adds a sixth chamber on the same 70mm depth and the same colour/woodgrain compatibility, so visually it's identical and the upgrade is invisible from outside.
Steel-reinforced frames, internally-beaded glazing
Every opening sash has a galvanised steel reinforcement core through the profile to keep the frame straight over decades of seasonal expansion. Glazing beads sit on the inside of the frame, so the glass cannot be removed from outside — a foundational requirement of PAS 24:2022 and a hard prerequisite for Secured by Design specification.
A+ BFRC, comfortably exceeds Approved Document L
Whole-window U-values of 1.2 W/m²K with a standard double-glazed Low-E unit, dropping to 0.9 W/m²K with triple glazing. The Approved Document L (Building Regs) maximum for replacement windows is 1.4 W/m²K — TOTAL70 clears that comfortably with the standard double-glazed spec, so you have headroom for darker or coloured frames (which sometimes degrade the U-value slightly) without ever falling below regulation.
Full Rehau colour and woodgrain range
Rehau's foiled finish range is the deepest in mainstream UK uPVC — Anthracite Grey, Chartwell Green, Black, White, Cream, plus Turner Oak, Light Oak and a number of other woodgrains. Foils are fused to the profile so they don't peel; warranted against fade on south-facing installations for 10 years, where most budget uPVC will visibly fade within 7-10 years.
PAS 24:2022 + Secured by Design compatible
All TOTAL70 opening profiles are PAS 24:2022 certified with multi-point shootbolt locking, internally-beaded glazing and laminated inner glass options on opening sashes. SBD-compatible configurations available where insurance or new-build specifications require it.

TOTAL70 — Frequently Asked Questions
What is Rehau TOTAL70?
TOTAL70 is Rehau's standard residential uPVC casement profile system — 70mm frame depth, 5-chamber multi-cavity construction, A+ BFRC energy rating, U-values from 1.2 W/m²K. It's the workhorse profile for Rehau casement windows, French doors, single doors and bay/bow window configurations across most UK installer ranges.
What is the difference between TOTAL70 and TOTAL70 Edge?
TOTAL70 is the 5-chamber baseline. TOTAL70 Edge is a thermal-upgrade variant on the same 70mm profile, adding a sixth internal air chamber for further insulation at the seal. Same frame depth, same colour/woodgrain compatibility, visually identical from inside or outside. Specified where extra thermal performance matters most without moving up to the cost of a triple-glazed unit.
What U-value can I expect from a TOTAL70 window?
Whole-window U-values from 1.2 W/m²K with a standard double-glazed Low-E unit and warm-edge spacer, dropping to about 0.9 W/m²K with triple glazing. For context, Approved Document L (the Building Regulations document for energy efficiency) sets a maximum of 1.4 W/m²K for replacement windows — TOTAL70 clears that comfortably with double glazing, so the system is fully compliant before any upgrades.
What products use the TOTAL70 profile?
TOTAL70 underpins our uPVC casement windows, French doors, single residential doors and bay/bow window configurations. Sliding sash windows are made by Victorian Sliders on Rehau profile (the truer period-correct sash); inline sliding patio doors use the Rehau AGILA system; flush casement windows use the Rio profile. Each profile is the right choice for its specific opening type — TOTAL70 is the casement workhorse.
Can TOTAL70 be specified in conservation areas?
Sometimes — it depends on the local planning authority and whether your property is listed. TOTAL70 is a flush-glazed casement profile rather than the deep-rebated heritage Rio profile, so for conservation properties where flush sash detail or a sash-window appearance is the planning expectation, the Rio (flush casement) or Victorian Sliders (sliding sash on Rehau profile) systems are usually the better fit. Listed buildings normally require timber. We handle the planning consultation and supporting paperwork as part of every quote.
How long does TOTAL70 last?
Rehau warrant the profile for 10 years against fading, warping and structural failure. In practice, Rehau TOTAL70 installations typically reach 25-30 years before replacement is needed — the foiled finish stays colour-stable, the steel-reinforced frames don't sag, and the multi-chamber profile keeps its thermal performance. Budget 3-chamber uPVC tends to need replacement at 15-20 years.
