Technolog hollow-chamber PVC trims - profiles with air chambers, white and wrapped in Renolit foil

PVC hollow-chamber trims - 5 (VARIO), 7 and 15 mm

Rigid PVC profiles with a rectangular section and internal air chambers. With and without a lip, with and without foam tape, white and foil-wrapped - Continental (Hornschuch), Renolit, LG, Cova. Length 6 m.

The chambered construction gives stiffness at low weight - the trim does not sag over a long run, yet still cuts with an ordinary saw. The version with a lip has a turned-up edge that hides small irregularities in the plaster beside the window.

The basic thicknesses are 7 mm (the most popular) and 15 mm. On top of that come the adjustable VARIO trims, 5 mm thick, and the 16 x 40 mm angled trim.

A different way of fitting - the trim clips on instead of being glued

A 15 mm trim with a lip that is fitted differently from the others: it is not stuck on with tape but clipped onto mushroom-head screws fixed into the substrate beforehand. This means the trim can be taken off and put back, for example when the roller shutter is serviced.

Hollow-chamber PVC trims - construction, thicknesses and choosing a profile

Plastic hollow-chamber trims are made of rigid PVC with a rectangular section. Air chambers run inside, stiffening the profile at low weight - which is why even a wide trim does not ripple over a long run. The basic thicknesses are 7 and 15 mm, and VARIO trims are 5 mm.

There are versions with a lip (a turned-up edge) and without. Trims with a lip work well around windows, because the lip hides small irregularities in the plaster where it meets the frame - so the edge does not have to be filled.

Most profiles are available with foam adhesive tape, which lets the trim be fitted without drilling and without wet work. Degrease the surface before bonding and leave expansion gaps at both ends of the run - PVC expands in summer and contracts in winter.

We wrap hollow-chamber trims with Continental (Hornschuch), Renolit, LG and Cova foils, the same ones used on window profiles, so the trim colour matches the joinery. The standard length is 6 metres.

PVC hollow-chamber trims - construction and thicknesses

Hollow-chamber trims are made of rigid PVC with a rectangular section and air chambers running inside the profile. The chambers stiffen the trim at low weight, so even a wide profile does not ripple over a long run, yet it can still be cut with an ordinary saw. The basic thicknesses are 7 mm (the most popular) and 15 mm, and the adjustable VARIO trims are 5 mm. The range is completed by the 16 x 40 mm angled trim. The standard length is 6 metres.

With a lip or without

A trim with a lip has a turned edge that covers the junction with the plaster. It works well when finishing windows, because it conceals small irregularities in the masonry and lets you skip filling the edge. A trim without a lip is a flat chambered profile, used where the edge is meant to stay visible or where the trim meets another finishing component. Both versions are available with self-adhesive foam tape and without.

VARIO trims - one trim instead of several sizes

VARIO is a 5 mm hollow-chamber trim with a row of notches on the underside. The profile snaps along the chosen notch and the width is matched to the particular reveal, instead of picking a ready size from the catalogue. Four items cover the range from 20 to 120 mm: 1001 (20-50 mm), 1002 (40-80 mm), 1006 (50-100 mm) and 1003 (60-120 mm). Accessories complete the system: angle connector 1004, corner connector 1005, U-profile end 509 and the trim-to-window connector 8826 for a 3-7 mm groove.

Fitting and colours

Most profiles have self-adhesive foam tape, so fitting needs no drilling and no wet trades. Before bonding, the surface must be degreased, and expansion gaps must be left at both ends of the run - PVC expands in summer and contracts in winter. We wrap the trims in Renolit and Continental (Hornschuch) foils, the same ones used on window profiles, so the colour of the trim matches the joinery.

Collection at the weekend too

We hand goods over during the week, but the collection time is agreed individually - including on a Saturday and, if need be, a Sunday, arranged by phone beforehand. The option is used above all by customers living and working in Germany, who collect their material when they come back to Poland. Orders for weekend collection should be placed by Friday 12:00 at the latest. We ship throughout Poland.

Frequently asked questions

What is a hollow-chamber trim?▼

A rigid PVC profile with a rectangular section and air chambers inside. The chambers stiffen the trim at low weight, so a wide profile does not ripple over a long run.

What does the lip on the edge of a trim do?▼

The lip is a turned edge that covers the junction between trim and plaster and conceals small irregularities in the masonry at the window. It lets you skip filling the edge.

What thicknesses of hollow-chamber trim are available?▼

The basic ones are 7 mm and 15 mm, with and without a lip. VARIO trims are 5 mm thick and the angled trim is 16 x 40 mm. The standard length of every profile is 6 metres.

What is a VARIO trim?▼

VARIO has a row of notches on the underside. The trim snaps along the chosen notch and the width is matched to the particular reveal, so one item replaces several ready sizes.

What widths do the VARIO trims cover?▼

Item 1001 covers the 20-50 mm range, 1002 the 40-80 mm range, 1006 the 50-100 mm range and 1003 the 60-120 mm range.

What is different about the angled 16 x 40 mm hollow-chamber trim?▼

It has one shorter leg - 40 and 35 mm with a 1.2 mm wall. The angle helps water run off and gives a softer transition at the window board.

Are hollow-chamber trims self-adhesive?▼

Most profiles come with self-adhesive foam tape, but we also carry versions without foam, for fixing with screws or adhesive.

What colours are hollow-chamber trims available in?▼

In white and foil wrapped with Renolit and Continental (Hornschuch), in a decor matched to the colour of the joinery.

How do I connect a hollow-chamber trim to the window frame?▼

The 8826 connector for a 3-7 mm groove is made for this. It takes any trim between 3 and 7 mm thick, VARIO profiles included.

What is a clip-on hollow-chamber trim?▼

A 15 mm trim with a lip that is not stuck on with tape but clipped onto mushroom-head screws fixed into the substrate. It can be taken off and put back, for example when the roller shutter is serviced.
