Why This System

Cascadia windows regularly achieve window energy ratings that exceed most other Canadian manufacturers. The fibreglass frame, combined with triple or quad glazing and warm-edge spacer bars, produces a system that loses very little heat through the frame itself. Because fibreglass and glass have the same thermal expansion rate, sill drainage on Cascadia windows experiences less movement-induced cracking than in uPVC systems. However, BC rainfall is heavy - drainage channel clearing is still essential at every visit in the Lower Mainland. The factory finish on Cascadia fibreglass frames is applied as a paint or gel coat. This surface responds differently from powder-coat on aluminium - it is more chemically sensitive to solvents but more resistant to abrasion than uPVC. Passive House airtightness detailing at the frame-to-wall junction uses vapour membranes and specialist tapes that are part of the certified building envelope. No water application at this zone during cleaning.

Official Care Guidance

No official guide published. The steps below are based on Justin Orloff's 25 years hands-on experience with this system.

Step 2 of 2: The Orloffs Protocol

The Orloffs Protocol

Since 1999 I've cleaned hundreds, if not thousands, of different window brands and systems. The physics of clean glass don't change from one brand to the next. Follow the steps below and you'll clean your Cascadia Windows & Doors windows to a professional standard โ€” guaranteed.

Pro Tools

My daily tool list. This is what I carry to every job.

1Microfiber T-bar applicator, kept clean and rinsed regularly to prevent grit
2Professional squeegee with a fresh rubber blade
3Extension pole for glass above arm height
4Bucket with at least 10 litres of water and enough soap for cleaning power without excess foam
5100% cotton towelling rags for edge detailing
6Vacuum for sill tracks and base profiles

Follow these steps in order. Each one builds on the last. This is the same sequence I use on every Cascadia Windows & Doors installation.

  1. 1

    Preparation -- before any water touches the glass

    Fill the bucket with at least 10 litres of water. Add soap for cleaning power -- enough to cut through environmental deposits, not so much you are fighting foam.

    Before touching the glass, brush down the surface to remove loose dust, spiderwebs, and debris. Any grit left on the glass during the wash phase risks scratching during agitation.

    Check the fibreglass frame condition before you start. Confirm which cleaning product is safe for that surface before opening any bottle.

    Cover anything below the windows that cannot be moved.

  2. 2

    Agitation -- apply and work the solution

    Dip the microfiber T-bar completely into the soap water, both sides. Remove excess water with your hand so it does not drip. Apply the solution across the entire glass surface with overlapping passes.

    The goal is to fully dissolve and release every deposit from the glass surface. Anything not released during agitation gets transported across the glass by the squeegee as a smear.

    For stubborn spots -- insect marks, salt residue, environmental deposits -- re-apply soap water and allow it to soak for a full minute before agitating again. Use more soap water, not more pressure.

    For panels above arm reach: attach the T-bar to an extension pole. Work in sections -- top first, then middle, then bottom -- keeping each section wet until you squeegee it.

    Rinse the T-bar cover regularly during the job. A dirty applicator causes microscopic scratches that accumulate over time.

  3. 3

    Detail the frame edge before squeegeeing

    Use your 100% cotton towelling rag, finger pressed into the fabric, to work into every junction and remove pooled soap water before the squeegee pass.

    This prevents drips running down onto already-cleaned areas during squeegeeing and keeps soap water out of drainage channels.

    On Cascadia Windows fibreglass frames, pay particular attention to the bottom edge where glass meets the frame sill -- water pooled here runs into drainage openings and leaves residue over time.

  4. 4

    The squeegee

    Tilt the squeegee at a slight angle so soap water spills from one side of the channel only -- not both. If the rubber is jumping or squeaking, either the rubber is not lubricated enough or the glass surface has warmed.

    Cutting in: start with the rubber blade making first contact on a dry edge of the glass.

    Side to side: horizontal passes across the panel. Works well on wide sections. Top to bottom: vertical passes down the panel. Works well on tall narrow sections.

    The J tune: one smooth unbroken motion top to bottom, wrist rotating at each end to reverse without lifting the rubber. The most efficient method on larger panels -- but it requires training before applying it to premium glass.

    Wipe the rubber dry after every pass. Overlap each stroke by 2-3 cm.

  5. 5

    Final edge detailing

    After squeegeeing, there is always a residual line of water along the bottom edge and at the panel sides. Take a dry cotton rag, fold to a clean corner, and detail these edges in one smooth pass.

    On Cascadia Windows frames, the bottom edge where glass meets the sill requires the most careful attention. Water left here runs into drainage and leaves residue that affects the next clean.

    Rotate the rag to a clean section after every pass. If the rag picks up grit at any point, replace it immediately.

  6. 6

    Frame wipe and hardware check

    On Cascadia Windows fibreglass frames: pH-neutral cleaner, soft cloth only. Fibreglass is scratch-resistant but coatings are not -- never use abrasive materials.

    Check that all drainage openings are clear and unobstructed. Water must be able to flow freely -- a blocked channel leads to accumulation that affects seal performance over time.

    Operate every opening window through its full range. Stiff handles or resistance at locking points indicate hardware that needs lubrication. Flag it to the owner rather than forcing it.

Pro Tips

  • On BC north-facing elevations, rinse the frame with the pure water pole before applying cleaning solution - you will remove most of the organic matter in the rinse and the cleaning step becomes much faster
  • On Passive House projects, confirm at the start of the job whether the building has been certified or is pre-certification - the airtightness membrane detailing at the frame perimeter may not yet be complete on pre-certification builds, and your water application rules differ
  • Cascadia lift-and-slide doors are heavy. Test the slide mechanism before cleaning the glass - a stiff mechanism before the clean means the hardware needs attention, and testing it after the clean associates the problem with your visit

What NOT To Do

  • Do not use solvent-based, acetone, or citrus-oil cleaners on fibreglass gel coat or painted surfaces
  • Do not use razor blades on glass without confirming that no inner-face Low-E coatings are present - Passive House glazing almost always has multiple coatings
  • Do not pressure-wash Cascadia windows - Passive House airtightness membranes at the frame-to-wall junction must not be disturbed
  • Do not use hard brushes on organic staining on north-facing fibreglass frames - soft cloth with dwell time is the correct approach
  • Do not skip sill drainage clearing in BC - 1,600mm of annual rainfall makes drainage capacity a maintenance issue, not a seasonal one

Field Notes

โ€œCascadia windows are specified by architects who care deeply about building performance. The clients on these projects have high expectations. A cleaning visit that leaves any residue on the fibreglass frame or disturbs any of the airtightness detailing is a professional failure. North-facing Cascadia frames in the Lower Mainland develop green algae staining between visits during the wet season. This is a predictable maintenance issue, not a product defect. Include it in the service description and price accordingly. The BC Interior market has different conditions from the Lower Mainland. If you have Cascadia clients in Kelowna or Kamloops, the freeze-thaw cycle check at spring visits is as important as the drainage clearing is in Vancouver.โ€
