Questions buyers actually ask.

Are fibreglass doors better than composite or uPVC?

Fibreglass (GRP) resists warping, rot and rust and holds its shape across temperature swings better than timber and many uPVC doors. GemRock engineers the full construction in-house. Verified comparative figures will be supplied by the client.

How long do GemRock fibreglass doors last?

Engineered for a long service life — placeholder for the client's verified guarantee terms and expected lifespan figure.

Do they need repainting?

No. Finishes are colour-stable and wipe-clean — no repainting cycle like timber.

What finishes and glazing options are available?

A range of colour finishes plus glazing and hardware options — see Finishes & options. The live count is editable in the CMS.
