Insulation and draught-proofing can protect your home against the cold in winter and the excess heat in summer.
It can even reduce noise pollution too! It is also important to understand that on a cold day, heat can escape your property in many different ways.
Here’s how you can resolve this issue dramatically.
When completing a loft conversion project, there are three ways in which you can insulate your home.
These methods are rigid insulation, flexible insulation and thermal lining boards.
Rigid insulation boards are available in various thicknesses, a factor that needs to be taken into consideration, specifically when converting a roof space.
Whilst cheaper products tend to be thicker, and consequently more effective, they can result in reduced headroom, which is often already lacking within a sloping roof room.
Therefore flexible insulation and thermal lining boards can be a useful and a good compromise in difficult to insulate areas and is therefore often used by our site staff.
The actual process of insulating a roofing structure itself usually uses either a ‘cold roof’ or ‘warm roof’ method.
The ‘cold roof’ method requires filling in the space between the rafters with a thick slab foam insulation material such as Celotex. The ‘warm roof’ method uses Celotex insulation over the rafters, as opposed to in between, to cover the capping.
This is then followed by the tile battens and tile work. This particular method is often used within dormer loft conversion projects, especially if a flat roof is present between the stud work.
Underfloor heating is also a popular choice for many of our customers, and mineral wool insulation is often considered to be a good choice of material. Laid between the floor joists at a depth of 250mm, not only does it provide excellent thermal and acoustic insulation, it is flame retardant properties will resist fire for at least 30 minutes!
An important part of loft insulation is choosing the right materials. Some of the most commonly used materials include:
- Metal roofing
Metal roofing usually comes in vertical slats that look like stone. While metal is a durable material, making it long-lasting and worth investment.
It may not be the best material to choose as it does not have insulating qualities and can be quite noisy in the rain.
Rubber is becoming a more and more common roofing material as it is both durable and reduces the amount of cold air being trapped in your loft.
- Stone-coated steel
This kind of roofing can be used as they are metal tiles covered in a stone layer, making them durable, avoiding damage, thus avoiding insulation risks caused by damage.
- SlateSlate is the most commonly used roofing material as it has been used for centuries in housing.
While slate can be expensive, it is waterproof and is moss resistant, meaning it is not susceptible to damage caused by bad weather.
Insulation right from the start
Site activity is co-ordinated by our national network of branches, staffed by informed, skilled professionals.
As the preferred choice of many of the national and regional housebuilders, you should hire a company who has built a good reputation over a number of years.
This will ensure that your project receives the right product at the right price at the right time.
The majority of roof insulations are installed using a traditional high-quality mineral fibre quilt.
However, initiatives such as The Code for Sustainable Homes have led many contractors to utilise innovative, high-performance products from such suppliers as Knauf, Rockwool, Kingspan and Celotex.
These boards and slabs offer premium thermal performance without compromising crucial ventilation to sloping areas and general warm roof constructions.
