Frequently asked questions and answers
- What does a complete thermo roof consist of?
For a complete thermo roof you have to use following::
- Corrugated sheets
- Side profiles (typically two pcs. in total)
- Collection profiles (Amount of corrugated sheets minus one)
- Profile endings (one pcs. pr. Collection and side profile)
- Top tape for the corrugated sheets top end
- Ventilating bottom tape
- Water noses (one pcs. pr. corrugated sheet)
You might need a wall profile on the spot where the thermo roof meets the house wall. A wall profile must be used if you want the thermo roof to be tight against the wall it is installed on. Often it is not necessary since there very often is an overhang above, where the thermo roof is installed, which means the overhang ensure there is no water entering the wall where the thermo roof is installed.

- Are acrylic sheets, Perspex® and PLEXIGLAS® the same?
No not quite. PLEXIGLAS® is an acrylic product and a registered trademark owned by German Evonik and it has some unique properties that not necessarily all acrylic based products have. We also sell Perspex® and Crylon® acrylic products from the world's largest acrylic manufacturers, which produce the highest quality of acrylic. Acrylic is actually called polymetamethyl acrylate, typically abbreviated PMMA, and is available in two variants. One is an extruded variant (XT) and the other is cast (CAST).

No, acrylic is not completely impact-proof. Do you need an impact-proof sheet then you can use polycarbonate – which by the way also is known as Lexan and Makrolon by other manufactures.
- Can you drill in acrylic?
- How unbreakable /impact-proof is polycarbonate?
Polycarbonate is a type of plastic sheet which almost cannot break. See this video to see the difference between acrylic and polycarbonate's breaking strength.
Polycarbonate is therefore especially useful as glass for the greenhouse which cannot break.See prices on break-proof greenhouse glass
- How do I adjust plastic sheets, like acrylic and polycarbonate?
It is easy. Use a fine toothed circular saw, jigsaw, hand saw or similar. See the video how to trim plastic sheets.

From the help of a bellows you can easily shape your plastic sheets in acrylic and Polycarbonate. See this video how you do it.
