FAQ
Will these really deter a determined burglar?
While no security product is foolproof, the plastic construction makes it significantly harder for an intruder to manipulate locks or break windows. The visual deterrent of added security measures can also be a factor in preventing attempted entry.
Are they easy to install on uPVC frames?
Most products are designed for straightforward installation with minimal tools – typically just a screwdriver. However, we recommend carefully reviewing the manufacturer’s instructions for specific fitting guidelines tailored to your door or window type.
Do these work with all wood frame types?
The plastic strips are generally compatible with most common wood frames, including softwood and hardwood. However, extremely old or warped wooden frames might require careful consideration of the fit and possible adjustments.
What’s the plastic material like – is it durable?
These products utilise a robust polypropylene plastic known for its weather resistance and strength. It's designed to withstand outdoor conditions and offer long-lasting protection against impact and weathering.
How do these compare in price to metal security options?
This range offers significant cost savings compared to traditional metal security products, providing a comparable level of protection at a much lower price point. You're getting effective security without the premium cost.
Do I need any special tools to fit them?
Generally, you’ll only need a Phillips head screwdriver for installation. Some products may benefit from a small file or trimming tool if there are minor adjustments required – always check the included instructions.
What size range do these covers come in?
The sizes vary depending on the product type and window/door dimensions, typically ranging from 30mm to 100mm. Please carefully review the product specifications for accurate measurements before ordering.
Will these affect my home’s insulation?
The plastic covers are designed to minimise any impact on thermal performance. However, it's always advisable to maintain a small air gap around windows and doors to optimise insulation values – consult with an energy advisor if needed.
What is the warranty like for these products?
Warranty terms are provided by the manufacturer of each individual product listed. Please check the product details on Amazon UK for specific coverage information, which generally covers manufacturing defects.
Can I use these on both internal and external doors/windows?
Yes, these plastic security strips and covers are suitable for both internal and external applications. The weatherproof material is designed to withstand varying environmental conditions and provide consistent protection regardless of the location.
