GB DIY Store 5 x uPVC Window Trickle Slot Vent White 400mm White - Reduces Condensation, Damp & Steam (5 Pack)

Received well packaged and in forecast. Vents were packed individually as complete units. Plastic was clean and no need to trim edges or drill out screw holes. Measurements accurate. Nice and unobtrusive, most important, do cut down on condensation

Great value, slightly to big on the vents even though it’s the correct measurements.

I bought these to replace the inner vents that had all been broken due to poor design. These replacements are great for the price and were easy to install. These replacements vents are much stronger than the existing ones. The open and closing mechanism is much easier to operate.

The product was as described, works well, easy to order and quickly dispathed.

My advice to anyone installing these to replace an existing 4 inch hole wall vent Is to drill no more than 3 holes with a 13mm drill bit unless you want arse froze off you. They are a bit cheap and flimsy but look OK and do the job. I had to seal up most of the holes I made due to the draft effect but everyone's situation is different due to wind direction and climate etc. So start small and see how it goes. Ventilation by itself doesnt solve condensation problems but helps. I've had huge condensation problems before and vents didn't work so if you have that problem trust me its not the way to go. I installed these because my old existing vents were the drafty. Ive now sealed most of the holes to suit my needs and happy

very simple to fit, even though l had to drill pilot holes for screws in the plastic windows as not quite the same centres. reason i only put 4 stars is the internal vent cover seems a little thin and flimsy, but used with care should be o.k. I'm happy with the product.

Good value looks good fittings

Althoytheyre decent one out of the 5 was broken and I didn't realise until after I had fit it!Easy to install though and everything you need.
